As per documentation we can use :test-matcher key to affect the test namespaces. If I use it for example to exclude some test (like #"(?!(app.render.test)).*"), and run lein bat-test cloverage, the test succesfully excluded, BUT cloverage instrument only this excluded namespace app.render.test and ignores all other namespaces.

As you can see in coverage report only one test ns present, though i have more than 10 namespaces
