* tests: use Git's test frameworkJohn Keeping2013-04-08
| | | | | | | | | | | | This allows tests to run in parallel as well as letting us use "prove" or another TAP harness to run the tests. Git's test framework requires Git to be fully built before letting any tests run, so add a new target to the top-level Makefile which builds all of Git instead of just libgit.a and make the "test" target depend on that.

* tests: "grep -e" is not portable to all platformsJohn Keeping2013-03-04
| | | | | | | | The "-e" option to grep is not needed unless specifying more than one pattern, which we don't do. Remove it to avoid restricting the tests on platforms that do not have a grep that recognises "-e". Signed-off-by: John Keeping <john@keeping.me.uk>
* Create initial testsuiteLars Hjemli2007-11-11
This creates a simple testsuite, heavily inspired by the testsuite in git. Signed-off-by: Lars Hjemli <hjemli@gmail.com>
