It seems like addToAssertionCount() must be provided by classes using this trait. How about adding it as abstract method to this trait?

It seems like fail() must be provided by classes using this trait. How about adding it as abstract method to this trait?

It seems like assertSame() must be provided by classes using this trait. How about adding it as abstract method to this trait?

                $expectedValue,
