* README.md: refactor "Running the tests"
This organises the section a little better. Previously some tests were
unmentioned; it read as if mypy_test and pytype_test were the only
tests. The section is now organised by test, making it easy to keep
track of the requirements and details of each. This also makes it
easier to add documentation for stubtest.
Also mention turning on Travis CI on your fork, since that is very
useful.
* README.md: document stubtest_test.py
* stubtest_test: add it
* travis: add stubtest_test to CI
* stubtest_test: add whitelists
This runs mypy both with Python 3.7 and 3.8. In Python 3.8,
mypy switched from using typed-ast to using Python's built-in ast.
This patch ensures that both are tested.
With today's release, pytype is able to fully load
stdlib/3/collections/__init__.pyi, so the test no longer needs the
ability to partially parse stubs using the pytd tool. Removing this
functionality allows the test code to be simplified considerably.
* Moves the pytype installation to requirements-tests-py3.txt, now
that pytype can run under Python 3.5+.
* Changes tests/pytype_test.py to not require a --python{version}-exe
argument when it can automatically find the Python interpreter, and
cleans up a few typos and out-of-date things.
* Updates the appropriate documentation.
* Updates .travis.yml.
This was already the configuration in Travis and it's been working fine. It's
confusing that Travis was using a different configuration than the default
when you run tests/mypy_test.py yourself.
This simplifies running flake8 tests and reduces the amount of F821 errors
reported (flake8-pyi enables support for forward references in *.pyi files).
The error code is left disabled until I clean up the remaining issues.
Ran both by Travis and locally. There's some setup required, README updated.
A few important Flake8 checks are still disabled, we're going to enable them as
soon as the stubs are fixed and we can reliably run Flake8 locally with Python
3.6.
