Unit testing the Controllers

As you develop the action methods in a Controller, it is highly recommended that you write the unit test for this code. To run the whole test suite:

> grails test-app

To run all tests for a single controller:

>grails test-app MyController

You can even run a single test

>grails test-app MyController testValidData

The results can be seen here:
./test/reports/html/all-tests.html
