How to test async function and task using Unit Test Library (Windows Store apps)?


  • Hi,

    I use ppltask library to implement some async function in my WinRT component. And I want to make a unit test for the function using Unit Test Library (Windows Store apps) that VS2012 provides. But I find if I call task::wait() function in a TestMethod, the method will crash!

    A simple demo is here:

    using namespace Microsoft::VisualStudio::CppUnitTestFramework;
    using namespace Sony::VAIO::SonySelect::ImageManager;
    using namespace concurrency;
    using namespace std;
    using namespace Platform;
    namespace UnitTestLibrary
                auto readTask  = create_task([]() -> String^
                    return "Test Async";
                auto str = readTask.get();

    I'm newbie for Unit Test Library (Windows Store apps). If I cannot call task::wait() function in the test method, how can I make an unit test for my async functions in WinRT component?
