`toBeFalsy()` returns true if the object or primitive evaluates to false
`wasNotCalledWith()` returns true if the object is a spy and was called with the passed arguments
`toContain()` returns true if an array or string contains the passed variable.
`toNotContain()` returns true if an array or string does not contain the passed variable.
