Add test assertion methods for checking warnings.
Review Request #10494 — Created April 2, 2019 and submitted — Latest diff uploaded
This introduces assertion methods for unit tests that checks if some
code either emits a warning (assertWarns
), or emits no warnings
(assertNoWarnings
). This simplifies the work that's normally needed
(usingwarnings.catch_warnings()
) to make basic warning testing
simple. It's mostly a port of Review Board'sassert_warns
.
Used this in other unit tests, which passed.
