@oliver.marks the error message says could not find: cljs.example.test_runner which means it was looking in paths for cljs/example/test_runner.cljs. so the full path would have one of the paths from paths prepended. so for example, test/cljs/ + cljs/example/test_runner.cljs. so that probably was a problem. glad you got it working.

@oliver.marks you can name test files something else if you want. no need to name them the same as what they're testing + -test. it's just a convention.
