677e88ef96* start test reorganization * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * move boolean ops * move more tests * Move more tests * more reorganization * more movements * mostly finish up reorganization * Finish reorganization tests in parent dir * try moving interface tests back * Move test_commands over * fix relative path to templates Co-authored-by: Darylgolden <darylgolden@gmail.com> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
