Support for very specific tests

[fogus]

Problem

The input into the test-runner test execution pipeline is limited to namespaces defined in clj source files only. However, it will only run tests on the CLASSPATH with the latest timestamp.

Background

When trying to run tests defined in AOT compiled files, test-runner is unable to find them because it favors nses defined in source files only. The reason for this is that the possible test namespaces set is built using the clojure.tools.namespace.find/find-namespaces-in-dir function. This function only locates namespaces in a subtree defined in source files.

However, test-runner will run compiled tests as long as their timestamps are more recent than those of the source files. The reason for this is that test-runner uses require which will load from the most recent source. I would find it more intuitive if I had a way to be more explicit about which tests I want to run.

Approach

From a high-level perspective, the input to the pipeline should be more explicit.
