 # Unit and integration tests for code under the /app directory
+####
 
 To run these tests, karma, node.js etc needs to be installed in the
 build environment.
 
-[Details to follow]
+From the karma installation directory, execute the following:
 
+    $ karma start {_path_to_}/src/main/webapp/tests/karma.conf.js
+
+This will launch and capture a browser, install and run the unit tests.
+
+The configuration is currently set to re-run the tests every time a
+file change is detected, (i.e. each time a source file is saved).
