java - 从 @RunWith 过渡到 @ExtendWith

Question

我需要methodInvoker的JUnit4在JUnit5将测试本身的执行包装在 lambda 中表达。给定的接口(interface)(例如 AfterTestExecutionCallback)将不允许操纵执行本身。请指导我 JUnit 4到5迁移？从 @RunWith 的转变至@ExtendWith 。如何使用 JUnit 5 包装测试本身的执行？

谢谢

您可以通过实现和注册一个InitationInterceptor来实现这一点

public class SwingEdtInterceptor implements InvocationInterceptor {

    @Override
    public void interceptTestMethod(Invocation<Void> invocation,
            ReflectiveInvocationContext<Method> invocationContext,
            ExtensionContext extensionContext) throws Throwable {

        AtomicReference<Throwable> throwable = new AtomicReference<>();

        SwingUtilities.invokeAndWait(() -> {
            try {
                invocation.proceed();
            }
            catch (Throwable t) {
                throwable.set(t);
            }
        });
        Throwable t = throwable.get();
        if (t != null) {
            throw t;
        }
    }
}

看起来您的用例可能是动态测试的候选者，又名测试:https://junit.org/junit5/docs/current/user-guide/#writing-tests-dynamic-tests -- 你尝试过吗？
