Assert keeps going after failure, but require immediately fails the tests, making it easier to find the output related to the test failure, rather than having to comb through a bunch of subsequent assertion failures. For equality tests, we may or may not want to continue, but for error checks we almost always want to immediately fail the test. Exceptions can be changed as-needed.
