Looking at the docs (it's even an example given), I should be able to run just the tests in /sapphire/tests with this command:
Likewise for just those tests contained in /mysite/tests (NOTE: most of these tests are in a subdirectory of /mysite/tests):
Neither return any output in the cli. Yet when I run an individual test contained in those directories, it's fine. Also running the above on other directories, such as /cms:
... works as expected.
It's obviously a configuration issue within or related to particular directories. but /sapphire seems strange.
Anyone have any thoughts?
