Why Automated Testing is important and when not to automate tests

The importance of testing is a renowned fact in the digital ecosystem. However, the fast-paced development environments of the present times often create time and cost constraints. Eventually, testing and QA get pushed to the back seat, and businesses fail to provide value to the users. The bugs that go undetected in the production environment will require a high maintenance cost. What do you do then? You turn to Automation testing and reap its results.

This is where Automated Testing comes into the picture; your team executes more tests in less time with improved overall test coverage. Automated testing is, as the name goes, “automated”. This process differs from manual testing, where you need a human to validate every product functionality single-handedly and ensure that it behaves as desired.  This testing is especially ideal for projects where similar test cases are run repeatedly. Common examples are cross-browser and cross-device testing. 

Benefits of Automation Testing

Automated testing enhances the team’s efficiency by many folds. Key benefits of automation testing include:

  • Seamless accuracy
  • Better test results reporting
  • Improved test case coverage
  • Easy and quick bug detection
  • Test case reusability
  • Less Painful Regression Testing
  • Scheduled testing

Humans are prone to make mistakes; a tester may miss out on a bug, especially when the app under audit has a lot of components/features. Automated Testing eliminates such common application testing mistake sand ensures that every component/feature is tested in the shortest possible time frame.

This testing process saves your staff from sticking to manual tests and focusing on other business priorities. Your QA team can reuse the automated test scripts so that the product is thoroughly tested the same way every time. Additionally, the process of finding bugs becomes spontaneous, which brings down the overall working hours.

When Should You Not Automate Testing?

Despite Automation testing simplifying your overall product verification process, it is not advisable to automate all the test cases.

The reason is plain enough: not everything can be automated.

And that is indeed true! Some test cases will require higher manual intervention than others, and it is necessary for every tester to make that differentiation. Here are some of the scenarios when you should not use automation for testing:

  • Rapidly changing software requirements with small and minute details addition/deletion
  • The testing processes that require definite manual exploration, such as ad-hoc testing and strategic thinking and planning
  • Test cases with low ROI
  • Implementing system installation and setup testing
  • For non-repetitive test cases
  • For exploratory and end-user usability testing
