Steps

1. Identify the Unit Test Scope:
   Identify the types of unit tests to be written. Positive unit tests exercise the code as intended and check for the right result. Negative unit tests intentionally misuse the code and check for robustness and appropriate error handling. Fault injection unit tests expose error-handling anomalies.

2. Write or Update the Unit Test:
   Identify unit tests for the development task covering as much of the functionality as possible. Perform write unit test, validate that the unit test fails, write or refactor code, and perform unit test until all of the identified tests for the task are completed.
   
   Write or update a single unit test at a time.
   
   Use scaffolding and mock objects to maximize the code surface area tested.
   
   If the code has already been written, generate unit tests from the working code.

3. Validate the Unit Test:
   Run the test, making sure the test fails for any element not completed and passes if the element is working as expected.
   
   Correct portions of the unit test that yield incorrect or ambiguous results.
