Angular was built from the ground up with testing in mind.

If people start out testing there, that may be one of the reasons they aren't very happy." It does the job and does it fast. However, having a clean interface and a test suite that's readable and easy to parse is just as important. If the tests can serve as living documentation to mesh with today's BDD style of development, that's ideal.
