Automated Acceptance Testing (and tool choice)...
Automated Acceptance Testing (and tool choice)
Automated acceptance testing has many names: acceptance-test driven development (ATDD), story-test driven development (STDD), agile acceptance testing and, most recently, specification by example. At the heart of all these approaches is to produce business-facing tests which are system tests running end-to-end, picking up regression issues and improving confidence that the code works as required.
In this talk, I will contextualise how each of these approaches share in common a three-tier layering strategy: acceptance criteria, test implementation layer and application driver layer. This is important because applying this approach requires a tool choice and each tool tends to have its own sweet (and blind) spot that is best understood through these layers.
I will first deep dive into sample code across a few tools (Cucumber, Fitnesse, Concordion) to illustrate this layering. I use an example that shows how to decouple the GUI from tests (window driver pattern).
Finally, I will look at some typical client scenarios to examine which tools might best suited because tool choice is not simply a host operating system question (.Net, Java, Ruby).
