This is "code snippets" for Microsoft Visual Studio 2012 or higher.

If you use these "code snippets", you can save time to coding/typing to create unit test code based on xUnit framework.

1. Download "xUnitTestCodeSnippets... .vsix" (Microsoft Visual Studio Extension) file from "Visual Studio Gallery" site.
   URL: https://visualstudiogallery.msdn.microsoft.com/032cd260-d4cd-4849-adff-648ea9a28265
2. Open (double click on Explorer) the downloaded "xUnitTestCodeSnippets... .vsix" file.
3. Then, "VSIX Installer" was launched. Please click "Install".

On C# source code in Visual Studio, you can insert xUnit Fact method by following key typing.

• xtestm [Tab]
  or
• fact [Tab]

Then, this snippet expanded following C# code.

[Fact]
public void MyTestMethod()
{

  // arrange
  
  // act
  
  // assert

}

And you can also insert xUnit Theory method.
if you type following keys,

theory

Then, this snippet expanded following C# code.

[Theory]
public void MyTheory()
{
  // arrange
  
  // act
  
  // assert
}

And you can also insert xUnit test class.
if you type following keys,

xtestc

Then, this snippet expanded following C# code.

public class MyTestClass
{
    [Fact]
    public void MyTestFact()
    {
        // arrange
        
        // act
        
        // assert
        
    }
}

• afact

[Fact]
public async Task MyTestFact()
{
  // arrange
  
  // act
  
  // assert
}

• atheory

[Theory]
public async Task MyTheory()
{
  // arrange
  
  // act
  
  // assert
}
