Library as trait(s) instead of inheritance class

[hotmeteor]

It would be awesome if these tools were provided as traits rather than a class to extend. We have an existing extended TestCase, so I can't use this out of the box and will need to roll my own trait.

Obviously not a big deal, just a suggestion.

Excellent theme you bring here. Well, my first idea was to create a trait, however the code depends on the the assertTrue existing in the TestCase class. It is strange have a code not contained itself. So it is open to discussion and pointing alternatives.

It could be based on an interface that is added to a TestCase class that requires implementation of the trait methods AND assertTrue. Then all requirements are enforced. It’s at least more flexible than an inheritance class.

Could you give an example?
