How to get console output in Visual Studio 2012 Unit Tests

Question

I have a managed C++ unit test in VS 2012. The test runs fine and I can verify that a loop with multiple cout calls is executed.

However when I look at the test explorer the test is marked as passed but there is no hyper link for the output as I am used to for c# projects.

The code at the end of my test is

for (int i = 0; i < 4; i++)
{
    cout << parameters[i];
    cout << endl;
}

which I can verify runs as I step through it in the debugger. I have also tried with cerr but no difference.

You can use Debug::WriteLine() (in the System::Diagnostics namespace) or Console::WriteLine() to write output to the Visual Studio 2012 console.

Code for the test (note that the System::Diagnostics namespace is declared elsewhere).

After clicking the "Output" link:

It is not using std::cout, but hopefully this will do what you need it to do.
