* only validating that we populate the DB correctly and that we make a call
* to the function Grader::grade(), without executing the contents.
*
* Solution: We create a phpunit mock of the Grader class. We create a fake
* object Grader with the function grade() which will always return true
* and expects to be excecuted once.
