* Use pytest to parametrize tests
Use built-in pytest test case parametrization support over external
'parameterize' package. The latter is not well maintained, and has
known Python 3.8 failures unsolved since November 2019.
Since pytest fixtures are incompatible with unittest-style tests,
rewrite the relevant test case to use pytest-style asserts. This also
makes the resulting code simpler, as we no longer have to pass TestCase
to the helper classes.
* Refactor input cleaning in ReplayingConnection.__readNextRequest()
A few test classes were failing to call tearDown() of the superclass,
which meant the file descriptors of their replydata files were leaking.
Make sure to call it, and switch every other callsite of superclasses by
name to using argument-less super().
Revert an AllTests change that snuck in during release.
* Handle unicode strings when recording responses (#1253)
* Add new test requirements
* Make requirement conditional
* Fix flake8 error
* Compare dict values without worrying about key order
* Improve readability
