java - junit5中的TestWatcher

我找不到像TestWatcher一样可以替代/工作的任何注释。

我的目标:
有2个功能取决于测试结果。

成功吗？做些

失败？做其他事情

最佳答案

此处介绍了TestWatcher API:

https://github.com/junit-team/junit5/pull/1393

https://junit.org/junit5/docs/5.4.0/release-notes/

如下使用它:

实现TestWatcher类(org.junit.jupiter.api.extension.TestWatcher)

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)

TestWatcher为您提供以下方法来对测试中止，失败，成功和禁用执行某些操作:

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

示例TestWatcher实现:

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，将其放在测试中:

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