example of test running in deps and cli guide not current?

[George Oliver]

hi, the example of test running at https://clojure.org/guides/deps_and_cli#test_runner may not be working (I'm new to Clojure so it's probable I'm doing something wrong too).

As written my terminal output was

lucretius:~/work/living_clojure/serpent-talk$ clj -X:test
No function found on command line or in :exec-fn

But using the example from the test runner repo at https://github.com/cognitect-labs/test-runner (which references the dependency differently) I received the expected output (my test ran).

Can you paste your full deps.edn file that's not working here? Also clojure --version output?

The git dependency format in the test-runner repo is the most current and you should prefer that one, but the older format should still be working too.

Thanks for the reply, here's a paste of a terminal session describing the issue:

In the one that didn't work, you missed the :exec-fn cognitect.test-runner.api/test line. That specifies the function to run and is why you got "No function found on command line or in :exec-fn".

I did sync up the site example to match the one on the test-runner repo so those are in sync now.

Hope that helps!

Thank you! That might have been a copy/paste mistake (I grabbed the old from the commit log) so I'm not sure if that's the error I originally hit. But it definitely works now.
