Gain a deeper knowledge of the test automation pyramid so you can keep a check on every test level and the return on investment at each of them. When you are well-informed, you’ll craft a strategy that benefits the ROI.
Automated tests were once considered way too expensive to write and afford every month. But that’s history now. Moreover, experts found that the reason why automation wasn’t working because developers were automating all the wrong levels.
A smooth and successful automation strategy considers three different levels, namely unit, service and UI. The test automation pyramid comprises of the same components. The pyramid was introduced by Mike Cohn.
On the base of this pyramid is unit testing, which should be the foundation of every test strategy. These tests provide information about bugs and other flaws to the developer. Then comes the service level.
Without service-level testing to fill the gap between unit and user interface testing, all other testing ends up being performed through the user interface, resulting in tests that are expensive to run, expensive to write, and brittle.
Every organization is made up of a bunch of services. Service is the response of an app to some input. Service level tests help in determining whether the process is running smoothly or not. On the top of this pyramid is user interface testing. This is placed at the top because we need to know what effects are occurring on the user level while using the software/app. Automated UI testing can inform you about your current standing and provides room for improvement.
Based upon the automation pyramid and agile testing methodologies, we have a few suggestions of testing software that you can use at your organization:
