如何在Visual Studio 2012单元测试中获取控制台输出 [英] How to get console output in Visual Studio 2012 Unit Tests

问题描述

我在VS 2012中有一个托管的C ++单元测试。该测试运行良好，我可以
验证是否执行了具有多个 cout 调用的循环。 / p>

但是，当我查看测试资源管理器时，测试标记为通过
，但是没有超级链接，因为我习惯了c＃
个项目。

测试结束时的代码为

  for（int i = 0; i< 4; i ++）
 {
 cout<参数[i]; 
 cout<<恩德尔
} 
  

在步入
时，我可以验证其运行调试器。我也尝试了
cerr ，但没有区别。

解决方案

您可以使用Debug :: WriteLine（）（在System :: Diagnostics命名空间中）或Console :: WriteLine（）将输出写入Visual Studio 2012控制台。

测试代码（请注意，System :: Diagnostics命名空间在其他地方声明）。

单击输出链接后：

它未使用std :: cout，但希望这样做会满足您的需要

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.

解决方案

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.
