Question

我正努力将一些测试从使用Nose转换为使用Pytest并扭曲，因为Nose已不再开发。转换测试的最简单方法是编辑每个测试所具有的自定义装饰器。这个装饰器在每个测试中，并定义单个测试的超时。

我已尝试使用@pytest.mark.timeout，但唯一有效的方法是“线程”＃39;方法，但这会停止整个测试运行并且不会继续进行下一个测试。使用方法＆＃39; signal＆＃39;无法停止测试，但我可以看到junitxml文件中存在错误。

def inlineCallbacksTest ( timeout = None ):

    def decorator ( method ):
        @wraps ( method )
        @pytest.mark.timeout(timeout = timeout, method = 'signal' )
        @pytest.inlineCallbacks
        def testMethod ( *args, **kwargs ):
            return method(*args, **kwargs)           
        return testMethod
    return decorator

测试本身使用twisted来启动并向软件发送消息。我不需要测试来取消任何扭曲的进程或锁。我希望pytest在超时后将测试标记为失败，然后进入下一个测试。

以下是使用信号超时方法时在xml文件中看到的错误。

我已经四处寻找类似的解决方案，而我能找到的最接近的是question。任何帮助或建议将不胜感激。

你如何超时使用pytest的扭曲测试？
