Improved in some tests the way to create entries.
Instead of defining the tests twice: the "create" method, and the entry
in the array, it is only needed in the array (ActionsTest, SpriteTest
and Texture2DTest)

here is to stip trailing newlines on those platforms, and also
to remove the newlines from the existing log messages.
