2022-05-16kunit: tool: misc cleanupsDaniel Latypov1-1/+1
This primarily comes from running pylint over kunit tool code and ignoring some warnings we don't care about. If we ever got a fully clean setup, we could add this to run_checks.py, but we're not there yet. Fix things like * Drop unused imports * check `is None`, not `== None` (see PEP 8) * remove redundant parens around returns * remove redundant `else` / convert `elif` to `if` where appropriate * rename make_arch_qemuconfig() param to base_kunitconfig (this is the name used in the subclass, and it's a better one) * kunit_tool_test: check the exit code for SystemExit (could be 0) Signed-off-by: Daniel Latypov <dlatypov@google.com> Reviewed-by: David Gow <davidgow@google.com> Reviewed-by: Brendan Higgins <brendanhiggins@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
2022-02-02kunit: fix missing f in f-string in run_checks.pyDaniel Latypov1-1/+1
We're missing the `f` prefix to have python do string interpolation, so we'd never end up printing what the actual "unexpected" error is.

2021-12-13kunit: add run_checks.py script to validate kunit changesDaniel Latypov1-0/+81
This formalizes the checks KUnit maintainers have been running (or in other cases: forgetting to run). This script also runs them all in parallel to minimize friction (pytype can be fairly slow, but not slower than running kunit.py). Example output: $ ./tools/testing/kunit/run_checks.py Waiting on 4 checks (kunit_tool_test.py, kunit smoke test, pytype, mypy)... kunit_tool_test.py: PASSED mypy: PASSED pytype: PASSED kunit smoke test: PASSED On failure or timeout (5 minutes), it'll dump out the stdout/stderr. E.g. adding in a type-checking error: mypy: FAILED > kunit.py:54: error: Name 'nonexistent_function' is not defined > Found 1 error in 1 file (checked 8 source files) mypy and pytype are two Python type-checkers and must be installed. This file treats them as optional and will mark them as SKIPPED if not installed. This tool also runs `kunit.py run --kunitconfig=lib/kunit` to run KUnit's own KUnit tests and to verify KUnit kernel code and kunit.py play nicely together. It uses --build_dir=kunit_run_checks so as not to clobber the default build_dir, which helps make it faster by reducing the need to rebuild, esp. if you're been passing in --arch instead of using UML.
