Flaky Windows test: clone remote git repository is too slow

[Brend-Smits]

Issue Report

Oftentimes, testing on a windows machine will fail because the test runs repolinter on a remote git repository is too slow. This test checks out the todogroup/repolinter repository fully and checks with default ruleset.

Proposed solution

Create a dummy-test repository that is used for these kinds of tests. As an example I created https://github.com/Brend-Smits/repolinter-tests

Windows tests never works for me :(

+1 to having a dedicated test repo.
