Provide a graphical model of the Test

-Driven Development (TDD) process as it would be

employed in support of agile methods such as Extreme Programming. Your model should

incorporate only the following process activities: (listed in no particular order) (10 marks)

A: Run the test together with other tests that have already been implemented. (

Show

two

possible outcomes of

this activity in your model: pass and fail)

B: Implement the new functionality and refactor.

C: Write and implement a test for the new functionality.

D: Identify the new functionality.

Use ovals (labeled A, B, C, or D to represent the four activities identified above), arrows,

diamonds, etc.
