1. Set up a separate test project referencing TUnit and TUnit.Assertions.
2. Create test classes matching the classes being tested.
3. Use the `[Test]` attribute for test methods and follow the Arrange-Act-Assert (AAA) pattern.
4. Implement standard tests using TUnit's fluent assertion syntax.
5. Implement data-driven tests using `[Arguments]`, `[MethodData]`, or `[ClassData]` attributes.
6. Utilize lifecycle hooks like `[Before(Test)]` and `[After(Test)]` for setup and teardown.
7. Run tests using `dotnet test` and analyze the results.
8. Refactor tests based on feedback and maintainability.
