The functions are responsible for checking the computer s role in the script. For example this test script states that the user clicks on the Dogs link on the home page. If the Dogs link is missing from the home page or spelled incorrectly the follow_link action stops and indicates that the test script has failed. This approach is called fast fail and makes it easy to write and maintain test scripts. In keeping with the movie script analogy it s like when the director sees computer screwing up its lines and yells cut . Everybody stops. The director corrects what s wrong and the actors start over again. The next section tests the search facility. We should be able to find our dog by searching for corgi CORGI and dogs wales. We aren t particularly interested in Corgis7 rather our goal is to test that the search mechanism is case-insensitive and supports multiple words. And most importantly the list of search results allows the buyer to place found animals in their cart easily. Shoppers should be given an opportunity to buy what they find. Group Multiple Paths . GROUP MULTIPLE PATHS The previous example demonstrated testing multiple paths that is different ways of doing the same thing. In one case we searched for a Female Puppy Corgi hierarchically and then we used the search box to find the same dog using different keywords. Here is another example that demonstrates multiple paths test_setup PetShop home_page follow_link Reptiles follow_link Rattlesnake add_to_cart Rattleless Rattlesnake remove_from_cart Rattleless Rattlesnake search_for Angelfish add_to_cart Large Angelfish update_cart Large Angelfish 0 7 Or other high-energy small dogs.
