Java 获取衍生测试以正确报告结果

我已经创建了一个自定义JUnit4运行程序（extends BlockJUnit4Runner），其目的是在运行这些测试之前运行其他测试有效所必需的测试。例如，如果您正在测试某些文件IO，则读/写测试将需要打开/关闭测试才能正常工作

这可以使用任意数量的requires正确地运行测试，对于不需要任何其他内容的测试，它可以很好地返回报告，但是当我运行一个确实需要另一个的测试时，我会得到“Done:1/2”，并且事件日志会显示“tests passed:1 passed”。即使要求的测试（第二次运行）失败，情况也是如此

您的自定义运行程序应该预先定义

org.junit.runners.ParentRunner#getDescription

，然后IDEA将正确显示树

@Override
protected void runChild(FrameworkMethod method, RunNotifier notifier) {
    if (!alreadyRunMethods.containsKey(method.getName())) {
        boolean requiredMethodsPassed = true;
        for (Annotation anno : method.getAnnotations()) {
            if (anno instanceof Requires) {
                requiredMethodsPassed = runRequiredMethods((Requires) anno, notifier, method);
                break;
            }
        }
        if (requiredMethodsPassed) {
            super.runChild(method, notifier);
        }else{
            notifier.fireTestAssumptionFailed(new Failure(describeChild(method), new AssumptionViolatedException("Required methods failed.")));
        }
    }
}

private boolean runRequiredMethods(Requires req, RunNotifier notifier, FrameworkMethod parentMethod) {
    boolean passed = true;
    for (String methodName : req.value()) {
        FrameworkMethod method = methodByName.get(methodName);
        if (method == null) {
            throw new RuntimeException(String.format("Required test method '%s' on test method '%s' does not exist.", methodName, parentMethod.getName()));
        }
        runChild(method, notifier);
        Boolean methodPassed = alreadyRunMethods.get(method.getName());
        methodPassed = methodPassed == null ? false : methodPassed;
        passed &= methodPassed;
    }
    return passed;
}
