 # current-test-applier
 
-# current-test-handler
+The test applier - what we do with non-skipped tests. Takes the same signature as `test-run`, should be responsible for evaluating the thunks, determining the status of the test, and passing this information to `current-test-reporter`.
 
 # current-test-skipper
 
+The test skipper - what we do with non-skipped tests. This should not evaluate the thunks and simply pass off to `current-test-reporter`.
+
 # current-test-group-reporter
 
+Takes one argument, a test group, and prints a summary of the test results for that group.
+
 # test-failure-count
 
+A running count of all test failures and errors across all groups (and threads). Used by `test-exit`.
+
 # current-test-epsilon
 
+The epsilon used for floating point comparisons.
+
 # current-test-comparator
 
+The underlying comparator used in testing, defaults to `test-equal?`.
