In Episode 4 of Testing All The Things we continue to create the driving licence generator we started in the previous two videos. In this video we create a mock random number generator to create random digits to the end of the driving licence number.
In episode 2 of Testing All The Things we start to exploring Test Doubles. Test doubles are used to isolate the code under test from its dependencies. Test doubles imitate the functionality of a dependency.
Creating test doubles do not require the use of a mocking framework. In the following videos we will not use a mocking framework so we can concentrate of the theory.
In the first video we are looking at the simplest form of Test Double, Stubs.
