We re really rolling now. The test_edit case is straightforward, and test_update is almost the same as test_create, so we ll jump straight to test_destroy.

First, we test that we can find the event in question, knowing full well that find will raise an exception if the event doesn t exist. Then we formulate a POST request to the destroy action, passing in the id of the event to destroy. We assert that the response is a redirect to the list action, and finally, we ensure that the event has in fact been deleted by asserting that Active Record raises a RecordNotFound exception.

Make sure your test file looks like the one in Listing 9-16 and run it using the Rake
test:functionals command, which will run our entire suite of functional tests. $ rake test:functionals
Loaded suite /usr/local/rake/rake_test_loader Started ......... Finished in 0.099709 seconds. 9 tests, 26 assertions, 0 failures, 0 errors
CHAPTER 9 TESTING YOUR APPLICATION
Not bad 26 assertions all in less than one second! You ve got to admit, this is a lot more efficient than manually clicking through your application to test it. Moreover, since this uses the test database, you don t risk polluting your production database with bogus data while you test. Whenever you make a change to your events controller, you can run this test to see if you ve broken any of your expectations. Now that we have unit and functional tests for events in place, let s run the entire test suite, which will run both our unit and functional tests. To do this, we use the built-in Rake task, test.
$ rake test
Loaded suite /usr/local/rake/rake_test_loader Started ........ Finished in 0.07121 seconds. 9 tests, 13 assertions, 0 failures, 0 errors Loaded suite /usr/local/rake/rake_test_loader Started ......... Finished in 0.099508 seconds. 9 tests, 26 assertions, 0 failures, 0 errors
Note We ve omitted some of the output here to cut down on the clutter. Your actual output will look
slightly different, but the summary (tests, assertions, failures, and errors) should be the same.
It may interest you to know that the default Rake task is to run all tests. That means running rake with no arguments is the same as running rake test.
Integration Testing
Rails defines one more type of test, and it s the highest level of the bunch. Integration tests go a little further than their functional equivalents. Unlike functional tests, which test a specific controller, integration tests can span multiple controllers and actions with

full session support. They re the closest we can get to simulating actual interaction with a web application.
