我刚遇到这种情况.

我想为我的反应堆添加一个失败的测试.反应堆永远不会完工. (它必须首先失败).但是我不希望测试永远运行.

I wanted to add a failing test for my reactor. The reactor never finishes. (it has to fail first). But I don't want the test to run forever.

我跟踪了您的链接，但仍然不满意.因此，我决定使用某些C ++ 14功能，并使它相对简单.

I followed your link but still not joy there. So I decided to use some of the C++14 features and it makes it relatively simple.

但是我实现了这样的超时:

But I implemented the timeout like this:

TEST(Init, run)
{
    // Step 1 Set up my code to run.
    ThorsAnvil::Async::Reactor                      reactor;
    std::unique_ptr<ThorsAnvil::Async::Handler>     handler(new TestHandler("test/data/input"));
    ThorsAnvil::Async::HandlerId                    id = reactor.registerHandler(std::move(handler));

    // Step 2
    // Run the code async.
    auto asyncFuture = std::async(
        std::launch::async, [&reactor]() {
                               reactor.run();   // The TestHandler
                                                // should call reactor.shutDown()
                                                // when it is finished.
                                                // if it does not then 
                                                // the test failed.
                            });

    // Step 3
    // DO your timeout test.
    EXPECT_TRUE(asyncFuture.wait_for(std::chrono::milliseconds(5000)) != std::future_status::timeout);

    // Step 4
    // Clean up your resources.
    reactor.shutDown();             // this will allow run() to exit.
                                    // and the thread to die.
}

现在我的测试失败了，我可以编写修复测试的代码了.

Now that I have my failing test I can write the code that fixes the test.
