使用 Visual Studio 测试运行器运行的 xUnit 测试的输出未显示在“输出"窗口中 [英] Output from xUnit tests run with Visual Studio test runner not shown in Output window

问题描述

我创建了一个名为 FooBarBaz 的全新 .NET Core 类库项目.然后我使用包管理器控制台运行:

• 安装包 xunit xunit
• 安装包 xunit xunit.runners.visualstudio

这是我添加的唯一代码:

使用Xunit；使用 Xunit.Abstractions;命名空间 FooBarBaz{公开课 Class1{私有只读 ITestOutputHelper 输出；public Class1(ITestOutputHelper 输出){this.output = 输出；output.WriteLine("从我的构造函数输出");}[事实]public void SmokeTest(){output.WriteLine("从我的测试中输出");断言.真(真);}}}

这直接基于

如何配置 xUnit 以在输出窗口中提供输出?

解决方案

在输入问题并摆弄更多之后，突然出现了完全晦涩的解决方案:只测试那些失败strong> 在输出窗口中显示 ITestOutputHelper 输出.

尝试将断言更改为 Assert.True(false);，您将得到:

不确定为什么这是默认设置，或者您将如何更改它.

I created a fresh .NET Core Class Library project named FooBarBaz. I've then used the package manager console to run:

• Install-Package xunit xunit
• Install-Package xunit xunit.runners.visualstudio

This is the only code I have added:

using Xunit;
using Xunit.Abstractions;

namespace FooBarBaz
{
    public class Class1
    {
        private readonly ITestOutputHelper output;

        public Class1(ITestOutputHelper output)
        {
            this.output = output;
            output.WriteLine("OUTPUT FROM MY CONSTRUCTOR");
        }

        [Fact]
        public void SmokeTest()
        {
            output.WriteLine("OUTPUT FROM MY TEST");
            Assert.True(true);
        }
    }
}

This is based straight on the xUnit.net documentation example. I know that the documentation goes on to talk about "Message Sinks" and whatnot, but I could've sworn I saw the message in the Output window of visual studio. In my real project this seems to work only erratically.

I know I can click the "Output" hyperlink after selecting a test and see it, but that's just one step extra, and that output doesn't have a monospace font either (which I'd like to have).

See this:

How do I configure xUnit to provide output in the Output window?

解决方案

After typing the question and fiddling around some more, the completely obscure solution popped up: only tests that fail show ITestOutputHelper output in the Output window.

Try changing the assertion to Assert.True(false); and you'll get this:

Not sure why that's the default, or how you'd change it.
