import-checkers: split tests of the tool from running it on the source
We did such splits for other tools already. The 'test-check-*.t' performs the
check of the source code while the regular tests verifies the tools works.
One of the benefit is that is provides a simple file to reuse in third party
extensions.
#require test-repo
$ . "$TESTDIR/helpers-testrepo.sh"
$ import_checker="$TESTDIR"/../contrib/import-checker.py
$ cd "$TESTDIR"/..
There are a handful of cases here that require renaming a module so it
doesn't overlap with a stdlib module name. There are also some cycles
here that we should still endeavor to fix, and some cycles will be
hidden by deduplication algorithm in the cycle detector, so fixing
these may expose other cycles.
Known-bad files are excluded by -X as some of them would produce unstable
outputs, which should be fixed later.
