unit-testing - TestNG 可以看到我的 Spock (JUnit) 测试结果吗？

Question

需要让 TestNG 运行我的 Spock 测试，因为 TestNG 用于整个系统的其余部分。
由于 TestNG 支持运行 JUnit 测试，我尝试了这个:

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="suiteTestName" verbose="1" junit="true">
    <test name="myTestName">
        <classes>
            <class name="mypackage.artifact.SomeArtifactSpecification" />
        </classes>
    </test>
</suite>

所以这实际上完美地运行了 Groovy 'SomeArtifactSpecification' Spock 单元测试。我可以从测试中看到一些 I/O，但是由于我是在 Eclipse 中运行的，所以我使用调试器来验证所有测试是否都在正确执行。我的类路径上有 TestNG-6.8.7 和 JUnit-4.10。问题是 TestNG 似乎不知道它做到了!这是最终输出:

===============================================
myTestName
Total tests run: 0, Failures: 0, Skips: 0
===============================================

有谁知道是否有可能让 TestNG 识别这些测试？

其他详细信息 - 为赏金添加

在下面的评论之一中，Peter 指出这取决于 TestNG 正在做什么。我尽可能地对此进行了调查。看起来 Junit 和 TestNG 都调用了 Spock 的 Sputnik 类第 63 行的“run”方法。但是，当直接从 JUnit 调用时，Sputnik 是从 JUnit4TestClassReference 调用的。从 TestNG 调用时，从 JUnitCore 调用 Sputnik。

所以问题仍然存在:如何让 TestNG 识别来自 Spock 的测试输出？如果我要长寿和繁荣，我真的需要知道!!!似乎答案可能是让 TestNG 与 JUnit4TestClassReference 一起运行，或者使用某种巧妙的包装器让 TestNG 做到这一点......

对于血腥的细节，我在下面发布了两个堆栈跟踪。第一个来自TestNG运行，它不起作用，第二个来自没有TestNG直接运行Spock。

来自 TestNG 的第一个堆栈跟踪:

直接运行 Spock 的第二个堆栈跟踪(有效)

Answer 1

我进一步调查了这一点，至少我找到了原因。

在下面的 org.testng.junit.JUnit4TestMethod 中，无法正确解析 Spock 测试名称。我在猜测，但我认为 Spock 使用了一种名称修饰来支持它允许的漂亮的文本方法名称。因此，即使下面的 TestNG 代码获得了“这是我的测试”这样的方法名称，它也无法通过所示方法解决该问题。我相信真正的方法名称类似于:$spock_feature_0_0

private static Method getMethod(Description desc) {
    Class<?> c = desc.getTestClass();
    String method = desc.getMethodName();
    try {
        return c.getMethod(method);
    } catch (Throwable t) {
        Utils.log("JUnit4TestMethod", 2,
                "Method '" + method + "' not found in class '" + c.getName() + "': " + t.getMessage());
        return null;
    }
}

因此，这会在调用 c.getMethod(method) 时引发异常 - 它无法将 Spock 方法名称解析为类上的实际方法。

似乎真正“搞砸了情况”的是，Junit (org.junit.runner.notification.RunNotifier) 在此代码中调用了上面的代码:

private abstract class SafeNotifier {
    void run() {
        synchronized (fListeners) {
            for (Iterator<RunListener> all= fListeners.iterator(); all.hasNext();)
                try {
                    notifyListener(all.next());
                } catch (Exception e) {
                    all.remove(); // Remove the offending listener first to avoid an infinite loop
                    fireTestFailure(new Failure(Description.TEST_MECHANISM, e));
                }
        }
    }

这段代码最好不要悄悄地删除监听器，而是记录它......
