+`cb(t)` fires with the new test object `t` once all preceeding tests have
+finished. Tests execute serially.
+
+Available `opts` options are:
+- opts.skip = true/false. See test.skip.
+- opts.timeout = 500. Set a timeout for the test, after which it will fail. 
+  See test.timeoutAfter.
 
 If you forget to `t.plan()` out how many assertions you are going to run and you
 don't call `t.end()` explicitly, your test will hang.
