+## Running the Tests
+
+To execute the test suite ...
+
+1. Run `lein cljsbuild test`. This will generate a suite of test HTML
+   files in the `public` directory (e.g., `test_no_opt.html`,
+   `test_advanced.html`, etc.). Each file runs `test.cljs` in the context
+   of the DOM, and each file represents a different compiler optimization
+   setting.
+2. Open each of the `public/test_*.html` files in a browser and [verify
+   that all the tests pass](https://skitch.com/jasonrudolph/85fga/domina-test-results).
