junit5中的TestWatcher

问题描述

我找不到像TestWatcher一样能替代/工作的任何注释.

I can't find any annotation which replace/working the same like TestWatcher.

我的目标:有2个函数会根据测试结果执行某些操作.

My goal:Have 2 functions which do something depend on test result.

• 成功吗?做点事
• 失败?做其他事情

推荐答案

几天前，TestWatcher被引入Junit 5.4.0:

TestWatcher was introduced to Junit 5.4.0 some days ago:

• https://github.com/junit-team/junit5/pull/1393
• https://junit.org/junit5/docs/5.4.0 /release-notes/
• https://junit. org/junit5/docs/current/api/org/junit/jupiter/api/extension/TestWatcher.html

• https://github.com/junit-team/junit5/pull/1393
• https://junit.org/junit5/docs/5.4.0/release-notes/
• https://junit.org/junit5/docs/current/api/org/junit/jupiter/api/extension/TestWatcher.html

要使用它，您必须:

1. 实施TestWatcher类(org.junit.jupiter.api.extension.TestWatcher)
2. 将@ExtendWith(<Your class>.class)添加到您的测试类中(我个人使用在每个测试中都扩展的基本测试类)( https://junit.org/junit5/docs/current/user-guide/#extensions )

1. Implement TestWatcher class (org.junit.jupiter.api.extension.TestWatcher)
2. Add @ExtendWith(<Your class>.class) to your tests classes (I personally use a base test class which I extend in every test) (https://junit.org/junit5/docs/current/user-guide/#extensions)

TestWatcher为您提供4种方法，用于在测试中止，失败，成功和禁用时做某事:

TestWatcher provides you with 4 methods to do something on test abort, failed, success and disabled:

• testAborted​(ExtensionContext context, Throwable cause)
• testDisabled​(ExtensionContext context, Optional<String> reason)
• testFailed​(ExtensionContext context, Throwable cause)
• testSuccessful​(ExtensionContext context)

• testAborted​(ExtensionContext context, Throwable cause)
• testDisabled​(ExtensionContext context, Optional<String> reason)
• testFailed​(ExtensionContext context, Throwable cause)
• testSuccessful​(ExtensionContext context)

https://junit. org/junit5/docs/current/api/org/junit/jupiter/api/extension/TestWatcher.html

TestWatcher实施示例:

Sample TestWatcher implementation:

import java.util.Optional;

import org.junit.jupiter.api.extension.ExtensionContext;
import org.junit.jupiter.api.extension.TestWatcher;

public class MyTestWatcher implements TestWatcher {
    @Override
    public void testAborted(ExtensionContext extensionContext, Throwable throwable) {
        // do something
    }

    @Override
    public void testDisabled(ExtensionContext extensionContext, Optional<String> optional) {
        // do something
    }

    @Override
    public void testFailed(ExtensionContext extensionContext, Throwable throwable) {
        // do something
    }

    @Override
    public void testSuccessful(ExtensionContext extensionContext) {
        // do something
    }
}

然后您将其放在测试中:

Then you just put this on your tests:

@ExtendWith(MyTestWatcher.class)
public class TestSomethingSomething {
...
