Now you can use `before` `before_each` `after` and `after_each`. Each of
the hooks will run in the context of the test file.
`before` This will run once before all the tests
`before_each` This will run before each of the test functions
`after` Will run once after all the test functions
`after_each` Will run after each one of the test functions
Multiple functions can be defined for each hook by calling the
respective function again.
