Test Automation So What exactly is Test Automation?

Test Automation is a method in software testing that leverages automation tools to control the execution of tests. Test automation is also called automated testing or automated QA testing.

According to the MarketsAndMarkets report, “the global test automation market size is anticipated to rise from USD 12.6 Billion in 2019 to USD 28.8 Billion by 2024 at a CAGR (Compound Annual Growth Rate) of 18.0 per cent during the prediction period”.

Test Automation Types of Automation Tests Let us look at the types of tests that can be automated and how they help test every aspect of the system enabling users to achieve a frictionless experience. 

Unit Tests: How well does your single unit of code work independently?



Integration and API Tests: How well does your system work when all units are integrated? Does it make or break the system? How well does your system work with external systems?



Regression Tests: How well does your system work when you add a new feature to your existing one? Has your software “regressed” after the new update? Every time you add a new feature or functionality, you need to check if there is any impact on the existing features



Performance Tests: How well do your software handle load and stress? How well is the responsiveness and stability of your software?



Smoke Tests: How well is your software’s stability? How well are your software’s functionalities working? Are there any showstoppers?



Security Tests: How well is your software secure from any vulnerabilities? Criteria to Choose Which Tests to Automate? The more automation you do, the more time you save. But this doesn’t mean you can automate everything! So, how do you choose the type of test cases that can be automated? To get the maximum Return on Investment (ROI), automate the test cases that fall under the following criteria:

  

High Volume and Repetitive tests that need to be run for every build like the smoke test, regression tests Business-Critical Tests Tests that need to run over multiple configurations/browsers/devices/OS/environment/hardware

Test Automation

Implementing a Test Automation Strategy  Quality, Agility and Continuous delivery go hand-in-hand in the software development cycle.  The Test Automation Strategy defines a framework for automated test scripts. It calls for automating tests at different levels.  Unit and Integration testing represents the base and majority of this test automation pyramid. Next comes, service layer, or API testing where the API tests are executed against the service layer.  And finally at the top of the pyramid are the GUI tests that validate the application as a whole at the presentation layer. Top it up with exploratory testing that identifies potential edge cases. Unlike scripted testing, exploratory testing uncovers unique and out-of-scope defects that would have otherwise been missed.
