• random.randint(0 , 10) - this will output a random number between 1 - 10
• random.choice([“dog”, “cat”, “bird, “mouse”]) - will randomly choose from the list
• random.shuffle([mylist]) - randomly shuffles the contents of the given list
• random.randrange(start, stop, step) - selects a random range and step sequence

What is Risk Analysis in Software Development

• This describes the process of identifying risk, assessing the severity, and making decisions to mitigate those risks.
• Certain risks cannot be avoided, such as the time used in tests, customer urgency, and incomplete requirements.
• Risk Magnitude can be assigned to each risk factor: High, Medium, Low
• Cause, Effect, and Likelihood, when applied to each risk factor, will help prioritize the order and need for mitigating solutions.

What is Test Coverage?

• Test coverage is looking for untested parts of code and ….getting it tested!

How Do You Know if You Have Done Enough Testing?

• You rarely get bugs that escape into production, and
• You are rarely hesitant to change some code for fear it will cause production bugs.

• It is certainly possible to test too much.
  • are your tests slowing you down?
  • can you remove tests without affecting coverage?
