In this book, we will simulate my personal experience of testing e-commerce systems. We will start by writing a very simple and crude test case, and we will refactor it and grow it into a stable and reliable test suite. A web store example might not apply to everyone's job, but the examples provided should be general enough to apply to any situation.
Today is our first day on the job; you and I are the sole members of the newly formed Quality Assurance team for the little start-up that sells Valentine's Day cards. It's a small company and the pay is not the greatest; however, just like any small start up, we get some company stock. This means that we can be very rich and famous if the website becomes popular. The website needs to stay operational and bug free, or our customers will never return and I will not be able to purchase that yacht I always wanted.
We know that we are short-staffed and need some automated tests to keep the quality high. However, first we need to convince the owner of the company that test automation is the right direction, instead of just testing everything by hand. We need to provide a cost-effective way to test the website and get quick results!
In this chapter, we will make an argument for using Selenium as our automation tool of choice and write a simple test to show how fast we can start building new tests. We will discuss the following topics along the way:
Why you should use Selenium over other tools
The Record and Playback pattern
The Selenium IDE
Recording a test with the Selenium IDE
Selenium WebDriver
Writing a test with Ruby
The Test::Unit testing framework
Interactive test debugging
