stantonk / run-tests-hook.sh

Last active August 29, 2015 14:23

In a mercurial or git pre-commit or pre-push hook: detect the type of project and invoke the appropriate test runner for various projects. So far Maven and Django projects are supported. Trivial to add others. No-ops on unknown project types.

	#!/usr/bin/env bash
	################################################################################
	# Use as a global mercurial/git pre commit or pre push hook to detect the type
	# of project and run unittests before allowing a commit or push to a remote
	# repository.
	#
	# Handy so that you don't have to remember to add test running hooks to every
	# repo clone/fork you have.

	# ******** MERCURIAL SETUP ***********
