unify test commands
Running tests in Stork right now is confusing. To tests, the commands are:
rake unittest_backend
rake ng_test
rake system_tests
It should be somewhat similar. How about this:
rake test_unit
rake test_ui
rake test_system
and maybe also add rake test_all
that runs all existing tests? Would be useful for review and sanity checks.
Also, cleaning up the rake names would be useful. Some are something_in_container
and others are something_in_docker
.
