test.go is a "Go script" for running Vitess tests. It runs each test in its own
Docker container for hermeticity and (potentially) parallelism. If a test fails,
this script will save the output in _test/ and continue with other tests.
Before using it, you should have Docker 1.5+ installed, and have your user in
the group that lets you run the docker command without sudo. The first time you
run against a given flavor, it may take some time for the corresponding
bootstrap image (vitess/bootstrap:<flavor>) to be downloaded.
It is meant to be run from the Vitess root, like so:
$ go run test.go [args]
For a list of options, run:
$ go run test.go --help
