1. Set up a separate test project with the naming convention `[ProjectName].Tests`.
2. Reference the necessary NuGet packages: `Microsoft.NET.Test.Sdk`, `xunit`, and `xunit.runner.visualstudio`.
3. Create test classes that correspond to the classes being tested.
4. Implement standard tests using the `[Fact]` attribute and the Arrange-Act-Assert (AAA) pattern.
5. Implement data-driven tests using `[Theory]` and data source attributes like `[InlineData]`, `[MemberData]`, or `[ClassData]`.
6. Use appropriate assertions to verify the expected behavior.
7. Organize tests by feature or component and use traits for categorization.
8. Run tests using the `dotnet test` command.
