Statistical analysis or simulation to investigate complex systems.

Random interaction with the system.

Question 2

Answer 2

Perform some task and check output

Question 3

Automated Testing

Answer 3

Automated tests are programmed to reduce effort.

Question 4

Define Refactoring

Answer 4

Change code that improves its structure but does not affect its behaviour.

Question 5

Give examples of bad coding practices.

Answer 5

• Duplicated Code
• Long Methods
• Poor Names (Make Parameter names descriptive!)

Question 6

Answer 6

• Setup method run and tear down method run after each execution of a test method.

Question 7

What does TDD provide?

Answer 7

• Simple easy to follow process
