transformAndAppend

Finishes the transformation process by carrying the transformation out and appending the assertions the given assertionCreator creates for the subject of type SubjectAfterTransformationT resulting from the transformation as single assertion.

I.e. the assertions the given assertionCreator creates are first collected and then appended which has the effect that we append a failing assertion in case assertionCreator does not create any assertion.

Return

The newly created Expect for the subject of type SubjectAfterTransformationT resulting from the transformation.
