This allows us to create a test project and add it to the solution.

Next, let’s type the following command to create the test project:

dotnet new mstest -n bookmarkr.UnitTests

This will create a new directory, named bookmarkr.UnitTests, in which the content of the test project will reside.

Right now, this directory only contains two files:

  • Bookmarkr.UnitTests.csproj, which describes the project, its configuration, and its dependencies
  • UnitTest1.cs, which acts as a sample test class
