`TestableMock` is still under heavy development, the following version plans may be adjusted during the iteration
|
||||
|
||||
- `v0.4` it's the current version, refer to the [issue](https://github.com/alibaba/testable-mock/issues) list for the work in progress
|
||||
- `v0.5` implementation mock class inherit mechanism, so that the same mock method can be reused between test classes conveniently
|
||||
- `v0.6` narrows the default effective scope of mock methods to the class under test, to avoid interaction of mocking cross classes
|
||||
- `v0.6` it's the current version, refer to the [issue](https://github.com/alibaba/testable-mock/issues) list for the work in progress
|
||||
- `v0.7` better anti-refactor support of mocking, allow quick mock all method in specified class
|
||||
- `v1.0` all functions are stable, a brand-new start

|
||||
|
||||
The main disadvantage of the current `TestableMock` is that the IDE cannot promptly prompt whether the method parameters are matched correctly when writing the mock method. If the mocking effect does not meet expectation, it has to be verified during runtime through the method provided in the [self-help troubleshooting](en-us/doc/troubleshooting.md) document. This feature needs to be provided by extending IDE plugins in the future.
|
||||
|
||||
In addition, because `TestableMock` uses the mock mechanism based on a single method in a unique way, it decouples the mock method definition from the unit test cases. Thus, the mock methods are by default reusable, and the unit test cases become cleaner and purer. On the other hand, the mock methods become fragmented, and life cycle management is relatively difficult. Therefore, it may take some time for developers get used to it.

How Mock Works
|
||||
---
|
||||
|
||||
This document mainly introduces the design and implementation principles of the mock function in `TestableMock`.
|
||||
|
||||
Unlike common mock-tools which write mock definitions in each test case, `TestableMock` allows each business class to provide its own set of mock methods, describing what should be mocked during testing, and define the corresponding replacement logic (that is, each business class has its own independent "Test class" and independent "Mock class"). By adopting "convention is better than configuration" principle, `TestableMock` not only reduce redundant codes but also reduce the cost of mock learning.
|
||||
|
||||
This design is based on two basic assumptions:

||||
|
||||
1. In any business class, methods that need to be mocked in one test case are usually required to be mocked in other test cases. For these mocked methods usually requiring external dependencies that are not easy to test.
|
||||
2. Each unit test only focuses on the logic inside the unit under test, and irrelevant calls outside the unit should be replaced with mocks. That is, the invocations that need to be mocked should all be in the code of the class under test.
|
||||
|
||||
Accordingly, the unit test scenarios that meet the above assumptions are simplified through conventions, and the remaining more complex use scenarios are supported through configuration.
|
||||
|
||||
The mechanism of `TestableMock` can be summarized in one sentence: <u>Using java agent to dynamically modify the bytecode, before the unit test is about to run, replace all invocations in the business class under test which match the mock method definition with invocations to the mock method itself.</u>.
|
||||
|
||||
The final effect is that no matter what service framework or object-container the code uses, no matter whether the object of mock target is injected by a framework, created by new operation, and whether the target method of mock is private or external, defined as global, local, static, inherited or overloaded, all can be mocked in a same and simple way, which make unit testing much easier.
|
||||
|
||||
> Notice: Mock's goal is the method invocation in the class under test. The code inside the test case will not be mocked, and the method definition itself has not changed, but the invocation code to those methods will be replaced.
|
||||
|
||||
Specifically, when the unit test is started, `TestableMock` will preprocess the classes loaded into memory and establish the association relationship between the "class under test", the "test class", and the "mock container class" respectively (can be one-to-one or many-to-one). On the one hand, this association is to correctly match the mock call and replace it before the test case is executed, and on the other hand, it is used to control the effective scope of the mock method.
|
||||
|
||||
For the class under test, replace the matched call with a call to the mock container method.
|
||||
|
||||
For the test class, insert the mock context initialization code at the beginning of each test case.
|
||||
|
||||
For the mock container class, add the `testableIns()` method to make the class become a singleton class, and insert codes to record the call at the beginning of each Mock method.
|
||||
|
||||
The above is the core logic of the entire mocking logic. For more implementation details, please refer to the source code. If you have any questions, suggestions, or improvement proposals, you are welcome to participate in the discussion and contribute through Github Issue and Pull Request 😃

|

|
||||
The `String` type in Kotlin language is actually `kotlin.String` instead of `java.lang.String`. However, when this type is built from bytecode, it will be replaced with Java's `java.lang.String` class, so no matter if the mock target is written as `kotlin.String` or `java.lang.String`, it cannot match the original called method.
|
||||
|
||||
In actual scenarios, there are very few scenarios where methods in the `String` class need to be mocked, so `TestableMock` has not dealt with this situation specifically.

The `Dalvik` and `ART` virtual machines of the Android system use a bytecode system different from the standard JVM, which will affect the normal functionality of `TestableMock`. The `Roboelectric` framework can run Android unit tests on a standard JVM virtual machine, which is much faster than running unit tests through the Android virtual machine. Recently, most Android App unit tests are written with the `Roboelectric` framework.

Parameter Constructor
|
||||
---
|
||||
|
||||
In unit testing, the preparation and construction of test data is a necessary and tedious task. Object-oriented layer-by-layer encapsulation becomes an obstacle to initializing the state of the object during testing. Especially when the type structure is complicated, there is no suitable construction method, or some fields need to use private inner classes, etc. Using conventional methods to construct those class often appear to be inadequate.
|
||||
|
||||
For this reason, `TestableMock` provides two minimalist tool classes, `OmniConstructor` and `OmniAccessor`, which makes the construction of any object no longer difficult.
|
||||
|
||||
### 1. Construct any object with one line of code
|
||||
|
||||
No matter how special the target type is, `OmniConstructor` will hand it to you immediately~~ The universal object constructor `OmniConstructor` has two static methods:
|
||||
|
||||
- `newInstance(<AnyClass>)` ➜ Specify any type, and return an object of that type
|
||||
- `newArray(<AnyClass>, <ArraySize>)` ➜ Specify any type, and return an array of that type
|
||||
|
||||
Usage example:
|
||||
|
||||
```java
|
||||
// Construct a object of "WhatEverClass" type
|
||||
WhatEverClass obj = OmniConstructor.newInstance(WhatEverClass.class);
|
||||
// Construct a array of "WhatEverClass[]" type with capability of 5
|
||||
WhatEverClass[] arr = OmniConstructor.newArray(WhatEverClass.class, 5);
|
||||
```
|
||||
|
||||
Beside that, object constructed by `OmniConstructor` is not just a simple empty object with all member values of `null`, but a "fullness" object in which all members and all sub-members of all members have been recursively initialized. Compared with using `new` operation, `OmniConstructor` can ensure the integrity of the object structure and avoid the `NullPointerException` problem caused by partial initialization of test data.
|
||||
|
||||
```java
|
||||
// Construct object using new operation
|
||||
Parent parent = new Parent();
|
||||
// Inner member is not initialized, will cause NullPointerException (❌)
|
||||
parent.getChild().getGrandChild();
|
||||
|
||||
// Construct object using OmniConstructor
|
||||
Parent parent = OmniConstructor.newInstance(Parent.class);
|
||||
// No need to worry, visit any child member safely (✅)
|
||||
parent.getChild().getGrandChild().getContent();
|
||||
```
|
||||
|
||||
> **Note 1**: In the current version, the member fields of type interface or abstract class will still be initialized to `null`, this problem will be fixed in the future.
|
||||
>
|
||||
> **Note 2**: Based on the light-weight principle, in the default mode, `OmniConstructor` will only uses the original constructor of the class to create objects. For POJO and most model layer objects, this mode has been able to meet the needs.
|
||||
> But for more complex situations, such as when certain class have constructors throwing exceptions or contain other statements that hinder the normal execution of the construction, the object construction may fail.
|
||||
> In those situations, you can use the [Testable global configuration](en-us/doc/javaagent-args.md) `omni.constructor.enhance.enable = true` to enable bytecode enhancement mode of `OmniConstructor`, in this mode, any Java class can be constructed.
|
||||
|
||||
In addition to use as input parameters of the method under test, `OmniConstructor` can also be used to quickly construct the return value of the mock method. Compared to using `null` as the return value of the mock method, using a fully initialized object can better guarantee the reliability of the test .
|
||||
|
||||
In the `DemoOmniMethodsTest` test class of the `java-demo` and `kotlin-demo` sample projects, it is shown in detail how `OmniConstructor` could be used when the target type has a multi-layered nested structure, the construction method is throwing exception, and even without public construction method available.
|
||||
|
||||
### 2. Access any inner member with one line of code
|
||||
|
||||
For test data, even with complex structure, it is usually only part of its attributes and states that are related to a specific test case. However, it is sometimes not easy to assign values to these fields deep wrapped in the object structure.
|
||||
|
||||
As an enhanced version of the `PrivateAccessor` tool, `OmniAccessor` is inspired by the [XPath node selector](https://www.w3schools.com/xml/xpath_syntax.asp) in the `XML` language, It provides two main static methods of `get` and `set`:
|
||||
|
||||
- `get(arbitrary object, "access path")` ➜ returns all member objects searched for based on path-matching
|
||||
- `set(arbitrary object, "access path", new value)` ➜ Assign a value to any objects based on path-matching
|
||||
|
||||
There is also a `getFirst()` method used to directly obtain the unique target object during exact path matching. Its function is equivalent to `OmniAccessor.get(...).get(0)`:
|
||||
|
||||
- `getFirst(arbitrary object, "access path")` ➜ returns the first member object searched based on path-matching
|
||||
|
||||
You only need to write the access path that meets the rules, no matter what type and depth of members, you can directly reach them with one line of code:
|
||||
|
||||
```java
|
||||
// Get all field of the parent object, which named as content and inside type GrandChild
|
||||
OmniAccessor.get(parent, "{GrandChild}/content");
|
||||
// Assign 100 to any fields which named as value and inside any child member that matches the 3rd item of the array named children
|
||||
OmniAccessor.set(parent, "children[2]/*/value", 100);
|
||||
```
|
||||
|
||||
The path rules are as follows:
|
||||
|
||||
**1. Matching member name**
|
||||
|
||||
The path name without additional decoration will match any member object with the same name
|
||||
|
||||
- `child`: match any descendant member whose name is `child`
|
||||
- `child/grandChild`: matches the child member named `grandChild` among the descendants of the name `child`
|
||||
|
||||
**2. Matching member type**
|
||||
|
||||
Use curly braces to match the type name, usually used to obtain or assign multiple member objects of the same type in batches
|
||||
|
||||
- `{Child}`: match all descendants of `Child`
|
||||
- `{Children[]}`: match all descendants of the `Children` array
|
||||
- `{Child}/{GrandChild}`: match all descendant members of `Child`, all types are children of `GrandChild`
|
||||
|
||||
The member name and type can be mixed on the path (currently it is not supported to specify the member name and type at the same time in the same level path)
|
||||
|
||||
- `child/{GrandChild}`: match all descendant members whose name is `child`, all types are child members of `GrandChild`
|
||||
- `{Child}/grandChild/content`: match all descendant members whose type is `Child`, the child members named `grandChild`, and the child members named `content`
|
||||
|
||||
**3. Use subscripts to access array members**
|
||||
|
||||
Use square brackets with numerical values to indicate that the matching position is an array type, and the object with the specified subscript is taken (without subscript, when the matching object is an array type, all objects in the array are matched)
|
||||
|
||||
- `children[1]/content`: match the descendant members of the array type named `children`, and take the child member named `content` in the `2`th object
|
||||
- `parent/children[1]`: match the child member of the array type named `children` among the descendant members named `parent`, and take the `2`th object among them
|
||||
|
||||
**4. Use wildcards**
|
||||
|
||||
Wildcards can be used to match member names or type names
|
||||
|
||||
- `child*`: match all descendant members whose name starts with `child`
|
||||
- `{*Child}`: match all descendant members whose type ends with `Child`
|
||||
- `c*ld/{Grand*ld}`: match the descendant members whose name starts with `c` and ends with `ld`, and the members whose type starts with `Grand` and ends with `ld`
|
||||
- `child/*/content`: At this time, `*` will match any member, that is, the child member of `content` contained in any child member of the `child` object
|
||||
|
||||
For details, see the use cases in the test classes of the `java-demo` and `kotlin-demo` sample projects `DemoOmniMethodsTest`.

||||
|
||||
### 3. Special instructions

||||
> **Do you really need to use `OmniAccessor`? **
|
||||
>
|
||||
> `OmniAccessor` implement the basic anti-refactoring mechanism based on the Fail-Fast principle. When the access path provided by the user cannot match any member, the `OmniAccessor` will immediately throw a `NoSuchMemberError` error, so that the unit test is terminated early. However, compared to the conventional member access method, the support of `OmniAccessor` in IDE refactoring is still weak.
|
||||
>
|
||||
> For content assignment of complex objects, in most cases, we recommend using [Builder Pattern](https://www.geeksforgeeks.org/builder-pattern-in-java/), or exposing Getter/Setter method implementations. Although these conventional methods are slightly clumsy (especially when you need to assign values to many similar members in batches), they are more friendly to the encapsulation and reconstruction of business logic.
|
||||
> Only when the original type is not suitable for transformation, and there is no other way to access the target member, `OmniAccessor` is the last resort.

Compared with `Mockito` and other mock tools where developers have to manually inject mock classes, `TestableMock` uses method name and parameter type matching to automatically find invocations that require mock. While this mechanism brings convenience, it may also cause unexpected mock replacement.
|
||||
|
||||
To troubleshoot mock-related issues, just add the `@MockWith` annotation to the test class, and configure the parameter `diagnose` to `MockDiagnose.ENABLE`, so the detailed mock method replacement process will be printed when the test is run.
|
||||
For this reason, `TestableMock` will automatically save the mock scanning log of the last test run in the project build directory. The default location is `target/testable-agent.log` (Maven project) or `build/testable-agent.log` (Gradle project).
|

|
||||
```java
|

@MockWith(diagnose = MockDiagnose.ENABLE)

- Self troubleshooting:
|
||||
According to the targeted test classes, below are some simple clues for self-troubleshooting. Suppose the class under test is "com.demo.BizService", the test class is "com.demo.BizServiceTest", and the mock container class is "com.demo.BizServiceTest.Mock":
|
||||
|
||||
- If there is no output, please check whether the `pom.xml` or `build.gradle` configuration correctly introduces `TestableMock` dependencies
|
||||
- If only the first line of `Handling test class` is output, please check whether the test class is in the same package of the class under test, and the name is "<ClassUnderTest>+Test" (required for `0.4.x` version)
|
||||
- If `Handling source class` and `Handling method xxx` are output, but there is no mock replacement happen at the expected code line, please check whether the mock method definition matches the target method
|
||||
- If the log file is no generated, please check whether the `pom.xml` or `build.gradle` configuration correctly introduces `TestableMock` dependencies
|
||||
- If only `com/demo/BizServiceTest$Mock` is found in the output, please check whether the mock class is created at correct place
|
||||
- If both the test class and the mock class are found, but the class under test `com/demo/BizService` not appeared, please check whether the test class is in the same package of the class under test, and the name is "<ClassUnderTest>+Test", otherwise `@MockWith` annotation should be used
|
||||
- If all the three classes are found, and `Found method xxx` are output, but there is no mock replacement happen at the expected code line, please check whether the mock method definition matches the target method

Upgrade to version 0.5
|

Upgrade Guide
|

---
|
||||
|
||||
After nearly a month of design and development, the `0.5` version of TestableMock has finally come out. Compared with the `0.4` version, the new version solves the three historical problems left over before:
|
||||
### Upgrade to v0.6
|
||||
|
||||
In version `0.6`,`TestableMock` provided a new [quick complicated class construction](en-us/doc/omni-constructor.md) capability. Meanwhile, it includes a modification that is incompatible with the `0.5` version: class `PrivateAccessor` have been moved from `com.alibaba.testable.core.accessor` package to `com.alibaba.testable.core.tool` package.
|
||||
|
||||
If you are using `PrivateAccessor` and having import statement like this:
|
||||
|
||||
```java
|
||||
import com.alibaba.testable.core.accessor.PrivateAccessor;
|
||||
```
|
||||
|
||||
When upgrade `TestableMock` to `0.6` version, please replace it as:
|
||||
|
||||
```java
|
||||
import com.alibaba.testable.core.tool.PrivateAccessor;
|
||||
```
|
||||
|
||||
### Upgrade to v0.5
|
||||
|
||||
The `0.5` version solves the three historical problems left over before:
|
||||
|
||||
1. <s>**Mock method cannot call other non-static methods**</s>. The mock method in the new version no longer has any difference from the ordinary method, and can access any external method and member variable.
|
||||
2. <s>**Mock method always acts on the entire test life cycle**</s>. From now on, the mock method supports restricting the effective scope to the test cases in the test class of which it belongs, so there is no need to worry about accidentally mocking cross-class test invocations.
|
||||
3. <s>**The MOCK_CONTEXT needs manually cleaned up and only supports class-level parallel testing**</s>. Now each test case has an independent `MOCK_CONTEXT` variable, no need to clean up after used, and you can use unit test with any parallel level.
|
||||
|
||||
In order to better realize the reuse of Mock methods, we have made a clear boundary between the mock class and the test class in the new version. When upgrading from `0.4` to `0.5`, the only change required is to wrap all mock methods in the test class with a `public static class Mock {}`.

Fast Mocking
|

---
|
||||
|

Compared with the class-granularity mocking practices of existing mock tools, `TestableMock` allows developers to directly define a single method and use it for mocking. With the principle of convention over configuration, mock method replacement will automatically happen when the specified method in the test class match an invocation in the class under test.
|
||||
In unit testing, the main role of the mock method is to replace those methods with **need external dependencies**, **with time-consuming**, **has random results**, or other effects that affect the development of the test, but do not affect the key the logic to be tested. Generally speaking, a certain call needs to be mocked, which is usually only related to its own characteristics, and has nothing to do with the source of the invocation.
|
||||
|
||||
Based on the above information, `TestableMock` has designed a minimalist mock mechanism. Unlike the common mock tools that uses **class** as the definition granularity of mocking, and repeats the description of mock behavior in each test case, `TestableMock` allows each business class (class under test) to be associated with a set of reusable collection of mock methods (carried by the mock container class), following the principle of "convention over configuration", and mock method replacement will automatically happen when the specified method in the test class match an invocation in the class under test.

TestableMock的设计和原理
|
||||
---
|
||||
|
||||
这篇文档主要介绍`TestableMock`中Mock功能的设计思想和实现原理。
|
||||
|
||||
与常见的Mock工具在每个测试用例里写Mock定义不同,`TestableMock`让每个业务类直接提供自己的Mock方法集合,描述自身在测试时需要被Mock的调用以及相应替代逻辑(即每个业务类有自己的独立Test类和独立Mock类)。采用约定优于配置,降低Mock学习理解成本、减少冗余信息。
|
||||
|
||||
这种设计基于两项基本假设:
|
||||
|
||||
1. 同一个测试类里,一个测试用例里需要Mock掉的方法,在其他测试用例里通常也都需要Mock。因为这些被Mock的方法往往访问了不便于测试的外部依赖。
|
||||
2. 每个单元测试只关注被测单元内部的逻辑,单元外的无关调用应该被替换为Mock。即需要被Mock的调用应该都在被测类的代码中。
|
||||
|
||||
据此通过约定来简化符合以上假设的单元测试场景,通过配置来支持其余更复杂的使用场景。
|
||||
|
||||
`TestableMock`的原理可以用一句话概括:<u>利用JavaAgent动态修改字节码,把被测的业务类中与所有与Mock方法定义匹配的调用在单元测试运行时替换成对Mock方法的调用</u>。
|
||||
|
||||
最终达到的效果则是,不论代码用什么服务框架、什么对象容器,不论要Mock的目标对象是注入的、new出来的、全局的还是局部的,不论要Mock的目标方法是私有的、外部的、静态的、继承来的或者重载过的,全部无差别通吃,让单元测试回归简单。
|
||||
|
||||
> 划重点:Mock的目标是**被测类**中的**方法调用**。测试用例里的代码不会被Mock,方法的定义本身没有变化,只是发起调用的代码被替换了。
|
||||
|
||||
具体来说,在单元测试启动时,`TestableMock`会对加载到内存中的类进行预处理,同时分别建立“被测类”、“测试类”、“Mock容器类”之间的关联关系(可以是一对一,也可以是多对一)。这个关联一方面是为了在测试用例执行时能够正确匹配Mock调用并进行替换,另一方面则是为了能控制Mock方法的生效范围。
|
||||
|
||||
对于被测类,将匹配到的调用换成对Mock容器方法的调用。
|
||||
|
||||
对于测试类,在每个测试用例开头插入Mock上下文初始化代码。
|
||||
|
||||
对于Mock容器类,增加`testableIns()`方法变成单例类,在每个Mock方法开头插入记录调用的代码。
|
||||
|
||||
以上是整个Mock的核心逻辑,更多实现细节,请参考源码。若有任何问题、建议、改进提议,都欢迎通过Github Issue和Pull Request参与讨论、贡献😃

`TestableMock`的许多功能采用了基于JavaAgent的运行时字节码修改实现。在JavaAgent启动时,可以通过两种方式调整`TestableMock`的执行过程。
|
||||
|
||||
## 1.使用全局配置文件
|
||||
|
||||
在项目的`src/test/resources`目录下创建一个名为`testable.properties`的文本文件,其中每行为一条配置项,配置项的名称与值之间用`=`连接。
|
||||
|
||||
对于大多数情况,我们更推荐使用配置文件来调节`TestableMock`的行为,这种方式相比Agent参数更加易读。
|
||||
|
||||

|
||||
| log.file | 指定TestableAgent日志文件位置 | 相对项目根目录的位置,例如:`target/testable/agent.log`,特殊值`null`表示禁用日志文件 |
|
||||
| log.level | 修改全局日志级别 | 可用值为:`mute`(禁止打印警告) / `debug`(打印调试信息) / `verbose`(打印非常详细的调试信息) |
|
||||
| mock.innerClass.name | 修改测试类中的内置Mock容器类名 | 任意符合Java类名的值,默认值为`Mock` |
|
||||
| mock.scope.default | 修改默认的Mock生效范围(详见[Mock生效范围](zh-cn/doc/scope-of-mock)) | 可用值为:`global`(全局生效) / `associated`(只对关联的测试用例生效) |
|
||||
| omni.constructor.enhance.enable | 是否启用`OmniConstructor`的字节码增强模式 | 可用值为:`true` / `false` |
|
||||
| omni.constructor.enhance.pkgPrefix.excludes | 对特定包禁用`OmniConstructor`的字节码增强模式 | 使用`,`分隔的包路径前缀列表,例如:`com.demo.model` |
|
||||
| thread.pool.enhance.enable | 是否启用基于`TransmittableThreadLocal`的Mock上下文存储 | 可用值为:`true` / `false` |
|
||||
|
||||
示例见`java-demo`和`kotlin-demo`项目中的`testable.properties`文件。
|
||||
|
||||
## 2.使用全局Agent参数
|
||||
|
||||
与其它基于JavaAgent的工具相似,`TestableMock`也支持通过在引入`testable-agent`包时,在末尾加上一个`=`符号,然后连接额外参数来传递用户的自定义参数。

快速构造复杂的参数对象
|
||||
---
|
||||
|
||||
在单元测试中,测试数据的准备和构造是一件既必须又繁琐的任务,面向对象的层层封装,在测试时就成为了初始化对象状态的重重阻碍。尤其遇到类型结构嵌套复杂、没有合适的构造方法、需要使用私有内部类等等状况时,常规手段往往显得力不从心。
|
||||
|
||||
为此`TestableMock`提供了`OmniConstructor`和`OmniAccessor`两个极简的工具类,从此让一切对象构造不再困难。
|
||||
|
||||
### 1. 一行代码构造任何对象
|
||||
|
||||
不论目标类型多么奇葩,呼唤`OmniConstructor`,马上递给您~ 万能的对象构造器`OmniConstructor`有两个静态方法:
|
||||
|
||||
- `newInstance(任意类型)` ➜ 指定任意类型,返回一个该类型的对象
|
||||
- `newArray(任意类型, 数组大小)` ➜ 指定任意类型,返回一个该类型的数组
|
||||
|
||||
用法举例:
|
||||
|
||||
```java
|
||||
// 构造一个WhatEverClass类型的对象
|
||||
WhatEverClass obj = OmniConstructor.newInstance(WhatEverClass.class);
|
||||
// 构造一个WhatEverClass[]类型,容量为5的数组
|
||||
WhatEverClass[] arr = OmniConstructor.newArray(WhatEverClass.class, 5);
|
||||
```
|
||||
|
||||
不仅如此,`OmniConstructor`构造出的绝非是所有成员值为`null`的简单空对象,而是所有成员、以及所有成员的所有子成员,都已经依次递归初始化的"丰满"对象。相比使用`new`进行构造,`OmniConstructor`能够确保对象结构完整,避免测试数据部分初始化导致的`NullPointerException`问题。
|
||||
|
||||
```java
|
||||
// 使用构造函数创建对象
|
||||
Parent parent = new Parent();
|
||||
// 内部成员未初始化,直接访问报NullPointerException异常(❌)
|
||||
parent.getChild().getGrandChild();
|
||||
|
||||
// 使用OmniConstructor创建对象
|
||||
Parent parent = OmniConstructor.newInstance(Parent.class);
|
||||
// 无需顾虑,安心访问任意子成员(✅)
|
||||
parent.getChild().getGrandChild().getContent();
|
||||
```
|
||||
|
||||
> **注意 1** :在当前版本中,类型为接口或抽象类的成员字段依然会被初始化为`null`,此问题将在后续版本修复
|
||||
>
|
||||
> **注意 2** :基于轻量优先原则,默认模式下,`OmniConstructor`仅利用类型原有的构造方法来创建对象,对于绝大多数POJO和`Model`层对象而言这种模式已经能够满足需要。
|
||||
> 但对于更复杂的情形,譬如遇到某些类型的构造方法会抛出异常或包含其他妨碍构造正常执行的语句时,对象构造可能会失败。
|
||||
> 此时可通过[Testable全局配置](zh-cn/doc/javaagent-args.md)`omni.constructor.enhance.enable = true`启用`OmniConstructor`的字节码增强模式,在该模式下,任何Java类型皆可构造。
|
||||
|
||||
除了用于构造方法的入参,`OmniConstructor`也可以用于快速构造Mock方法的返回值,相比将`null`作为Mock方法的返回值,使用完全初始化的对象能够更好保障测试的可靠性。
|
||||
|
||||
在`java-demo`和`kotlin-demo`示例项目的`DemoOmniMethodsTest`测试类中,详细展示了当目标类型有多层嵌套结构、构造方法无法正常使用,甚至没有公开的构造方法时,如何用`OmniConstructor`轻松创建所需对象。
|
||||
|
||||
### 2. 一行代码访问任意深度成员
|
||||
|
||||
对于测试数据而言,即使是结构复杂的参数对象,与特定测试用例有关的通常也只是其中的部分属性和状态,然而要为这些深藏在对象结构内部的字段赋值有时却并非易事。
|
||||
|
||||
做为`PrivateAccessor`功能的加加加强版,`OmniAccessor`的灵感来自于`XML`语言中的[XPath节点选择器](https://www.w3school.com.cn/xpath/xpath_syntax.asp),它提供了`get`、`set`两个主要的静态方法:
|
||||
|
||||
- `get(任意对象, "访问路径")` ➜ 返回根据路径匹配搜索到的所有成员对象
|
||||
- `set(任意对象, "访问路径", 新的值)` ➜ 根据路径匹配为指定位置的对象赋值
|
||||
|
||||
还有一个用于精确路径匹配时直接获取唯一目标对象的`getFirst()`辅助方法,其作用等效于`OmniAccessor.get(...).get(0)`:
|
||||
|
||||
- `getFirst(任意对象, "访问路径")` ➜ 返回根据路径匹配搜索到的第一个成员对象
|
||||
|
||||
只需书写符合规则的访问路径,不论什么类型和深度的成员,都可以一键直达:
|
||||
|
||||
```java
|
||||
// 返回parent对象中,所有符合类型是GrandChild的子对象中叫做content的成员对象
|
||||
OmniAccessor.get(parent, "{GrandChild}/content");
|
||||
// 将parent对象中,符合名称为children的数组第3位的任意子成员的value字段赋值为100
|
||||
OmniAccessor.set(parent, "children[2]/*/value", 100);
|
||||
```
|
||||
|
||||
具体路径规则如下:
|
||||
|
||||
**1. 匹配成员名**
|
||||
|
||||
不带额外修饰的路径名将匹配与之同名的任意成员对象
|
||||
|
||||
- `child`: 匹配任意名字为`child`的子孙成员
|
||||
- `child/grandChild`: 匹配名字为`child`的子孙成员里,名为`grandChild`的子成员
|
||||
|
||||
**2. 匹配成员类型**
|
||||
|
||||
使用花括号匹配类型名称,通常用于批量获取或赋值同类的多个成员对象
|
||||
|
||||
- `{Child}`: 匹配所有类型是`Child`的子孙成员
|
||||
- `{Children[]}`: 匹配所有类型是`Children`数组的子孙成员
|
||||
- `{Child}/{GrandChild}`: 匹配所有类型是`Child`的子孙成员里,所有类型是`GrandChild`子成员
|
||||
|
||||
成员名和类型可以在路径上混用(暂不支持在同一级路径同时指定成员名称和类型)
|
||||
|
||||
- `child/{GrandChild}`: 匹配名字为`child`的子孙成员里,所有类型是`GrandChild`的子成员
|
||||
- `{Child}/grandChild/content`: 匹配所有类型是`Child`的子孙成员里,名为`grandChild`子成员里的,名为`content`的子成员
|
||||
|
||||
**3. 使用下标访问数组成员**
|
||||
|
||||
使用带数值的方括号表示匹配该位置为数组类型,且取指定下标的对象(不带下标时,当匹配对象为数组类型,默认匹配数组中的所有对象)
|
||||
|
||||
- `children[1]/content`: 匹配名称为`children`的数组类型子孙成员,取其中第`2`个对象中名为`content`的子成员
|
||||
- `parent/children[1]`: 匹配名称为`parent`的子孙成员里,名为`children`的数组类型子成员,取其中第`2`个对象
|
||||
|
||||
**4. 使用通配符**
|
||||
|
||||
通配符可以用于成员名或类型名的匹配
|
||||
|
||||
- `child*`: 匹配名称以`child`开头的所有子孙成员
|
||||
- `{*Child}`: 匹配类型以`Child`结尾的所有子孙成员
|
||||
- `c*ld/{Grand*ld}`: 匹配名称以`c`开头`ld`结尾的子孙成员里,类型以`Grand`开头`ld`结尾的成员
|
||||

此外,在单元测试中时常会需要对被测对象进行特定的成员字段初始化,但有时由于被测类的构造方法限制,使得无法便捷的对这些字段进行赋值。那么,能否在不破坏被测类型封装的情况下,允许单元测试用例内的代码直接访问被测类的私有方法和成员字段呢?`TestableMock`提供了两种简单的解决方案。
|
||||
|
||||
### 方法一:使用`@EnablePrivateAccess`注解
|
||||
### 1.1 使用`PrivateAccessor`工具类
|
||||
|
||||
只需为测试类添加`@EnablePrivateAccess`注解,即可在测试用例中获得以下增强能力:
|
||||
|
||||
- 调用**被测类**的私有方法(包括静态方法)
|
||||
- 读取**被测类**的私有字段(包括静态字段)
|
||||
- 修改**被测类**的私有字段(包括静态字段)
|
||||
- 修改**被测类**的常量字段(使用final修饰的字段,包括静态字段)
|
||||
|
||||
访问和修改私有、常量成员时,IDE可能会提示语法有误,但编译器将能够正常运行测试。(使用编译期代码增强,目前仅实现了Java语言的适配)
|
||||
|
||||
效果见`java-demo`示例项目`DemoPrivateAccessTest`测试类中的用例。
|
||||
|
||||
> 此功能默认假设测试类与被测类同包,且名称为`被测类+Test`。当不符合此约定时,可在测试类的`@EnablePrivateAccess`注解上使用`srcClass`参数指定实际的被测类。例如:
|
||||
>
|
||||
> ```java
|
||||
> @EnablePrivateAccess(srcClass = DemoServiceImpl.class)
|
||||
> class DemoServiceTest() { ... }
|
||||
> ```
|
||||
|
||||
### 方法二:使用`PrivateAccessor`工具类
|
||||
|
||||
若不希望看到IDE的语法错误提醒,或是在非Java语言的JVM工程(譬如Kotlin语言)里,可以借助`PrivateAccessor`工具类来直接访问私有成员。
|
||||
|
||||
这个类提供了7个静态方法:

|
||||
### 1.2 防代码重构机制
|
||||
|
||||
### 私有成员编译期校验
|
||||
本质上来说,`PrivateAccessor`只是JVM反射机制的“易用型”封装,因此会存在与JVM反射相同的“对代码重构不友好”问题。当被测类中的私有方法名称、参数进行了修改,由于IDE无法自动订正反射访问的代码,往往相关错误要在单元测试运行时才能被发现。
|
||||
|
||||
上述两种私有成员访问功能的本质都是利用了JVM的反射机制,但JVM编译器不会检查反射目标的存在性,当代码重构时,如果对源类型中的私有方法名称、参数进行了修改,就会导致错误要在单元测试运行时才能被发现。为此,`@EnablePrivateAccess`注解的另一项功能是为**被测类**的私有成员访问进行额外的编译期校验。
|
||||
为此,`TestableMock`对`PrivateAccessor`进行了增强,赋予其编译期私有成员校验能力。这项功能默认关闭,需要通过`@EnablePrivateAccess`注解开启。(实际上是通过该注解的`verifyTargetOnCompile`参数控制,由于此参数默认值为`true`,因此只需在被测类上添加该注解即可启用私有成员校验)
|
||||
|
||||
**注意**:当私有成员校验功能开启时,`PrivateAccessor`工具类将只能用于访问**被测类**的私有成员,这会有助于限制将`PrivateAccessor`工具类用于与当前测试无关的“越权”操作。如果确实需要访问其他类的私有成员,可将`@EnablePrivateAccess`注解移除,或将注解的`verifyTargetOnCompile`参数设为`false`,手工关闭校验功能。
|
||||
**注意 1**:当私有成员校验功能开启时,`PrivateAccessor`工具类将只能用于访问**被测类**的私有成员,从某种角度而言,这也有助于限制将`PrivateAccessor`工具类用于与当前测试无关的“越权”操作。
|
||||
|
||||
**注意 2**:`TestableMock`默认约定测试类与**被测类**的包路径相同,且名称为`被测类+Test`。若测试类名称不符合此约定时,在使用`@EnablePrivateAccess`注解时,需用`srcClass`参数显式指明实际的**被测类**位置。
|
||||
|
||||
**注意 3**: 此机制目前只针对`Java`语言实现,对于`Kotlin`以及其他JVM方言均无效。
|
||||
|
||||
> 将`DemoPrivateAccessorTest`示例代码稍加修改,添加`@EnablePrivateAccess`注解(注意此时测试类名不符合约定,需加`srcClass`参数):
|
||||
>
|
||||
> ```java
|
||||
> @EnablePrivateAccess(srcClass = DemoPrivateAccess.class) // <- 添加此行
|
||||
> class DemoPrivateAccessorTest() { ... }
|
||||
> ```
|
||||
>
|
||||
> 然后将任意一处通过`PrivateAccessor`访问的目标名称改为实际不存在的成员名,再次编译时即可发现该行有编译错误,提示信息为访问目标不存在。
|
||||
|
||||
### 2.1 直接访问私有成员
|
||||
|
||||
第二种方法,除了借助`PrivateAccessor`工具类以外,凡是使用了`@EnablePrivateAccess`注解的测试类还会被自动赋予以下“特殊能力”:
|
||||
|
||||
- 调用**被测类**的私有方法(包括静态方法)
|
||||
- 读取**被测类**的私有字段(包括静态字段)
|
||||
- 修改**被测类**的私有字段(包括静态字段)
|
||||
- 修改**被测类**的常量字段(使用`final`修饰的字段,包括静态常量字段)
