I have a code that uses Math.random(). I must test the case when the random value is less that 0.5.

• I can't. Random is random!

• I loop in my test until a value less than 0.5 is returned

• I should not use Math.random() in my application

• I introduce a new service that encapsulates Math.random(), and fake that service in my test

What is the main reason why tests should be fast?

• Because it consumes less resources and energy

• Because it demonstrates that my application is fast

• Because it allows me to run them often while I'm working

• Because I told you they should

• Some code is complicated because we had to solve a performance issue

What is a key to avoid being overwhelmed with technical dept?

• Writing good code from the beginning

• Making technical sprints from time to time

• Having a lot of tests
