[Answer]-Django Jenkins Test runner – Slow

To exclude the coverage task, define TEST_TASKS in your project’s settings.py, and leave out the coverage task.

TEST_TASKS = (
    # 'discover_jenkins.tasks.run_pylint.PyLintTask',
    'discover_jenkins.tasks.with_coverage.CoverageTask',
)

I’m not sure why you don’t want to edit settings.py, that’s the documented way to do it.

Check the latest version of original django-jenkins library. It has same unit test discovery method and coverage disabled by default. Coverage could be enabled with --enable-coverage command line option.
