usage: git-test [<range>] [-t <command>] [-n] [-k] [-f] [-c <path>]
Run automated tests against each commit of a range of commits in a Git
repository.
When no <range> is given, master..HEAD is assumed.
OPTIONS
-b <base>, --base=<base>
-t <command>, --test=<command>
Run <command> against each commit. It is run on a shell, with the
current working directory at the top of the working tree. This may
be used multiple times.
When this option is not specified, the value(s) of the
configuration 'git-test.test' is used.
-n, --dry-run
Do everything except actually check out the tree and run the test
commands.
-k, --keep-going
Continue as much as possible after a test failure.
-f, --force
Ignore the cached test result.
-c <path>, --checkout=<path>
Checkout a tree at <path> (relative to the top of the current
working tree) instead of $GIT_DIR/git-test/current.
This can be also configured by 'git-test.checkout'.
