What You Should Know Before Shifting to Testing Automation

You are here

automationRapid development of new technologies creates for IT companies both substantial benefits they can use and significant challenges they must fight off swiftly and efficiently to keep up with the pace of changes. Mushrooming number of mobile and web applications, utilizing Agile development instead of Waterfall and more are literally pushing software development companies towards implementing testing automation. If you are among them and you are considering such kind of transition too, here are some helpful tips you should read to do it more fruitfully and less painfully.

Don’t try to automate everything. Mix the strategies in the most efficacious way.


  • Regression testing. Nowadays more and more IT businesses are shifting their focus to agile development. Agile development methodology stimulates on-time or early release and continuous improvement of software. It calls as well for prompt and timely feedback. This substantially reduces the time allocated for regression testing and presents a challenge only automatic testing can successfully accept. In fact, it is virtually impossible to utilize Agile as your development lifecycle sticking only with manual testing. If regression testing is performed manually, the feedback may be significantly delayed. As a result, a team receives bug reports much later than expected. Deferment can last up to 6 months, actually turning Agile sprints into Waterfall phases.
  • Load-testing of web applications. If you have to test what load your web solution can withstand, automation really comes in handy. Such load testing tools as JMeter enable you to simulate thousands of virtual users interacting with your web applications. The task would be almost insurmountable to accomplish if manual testing was used.
  • Test cases which will be run with various test data, conditions, and environments.
  • Tests run with different configurations.
  • Tests which are laborious and susceptible to human error.
  • Testing frequently used functions.


  • Tests that are run once. Automating a test case is 4-8 times longer than a manual test takes. Thus to ensure automated test case is profitable, it needs to be run more than 4-8 times.
  • Usability testing. Testing which takes human touch and perception.
  • Exploratory testing (when you don’t have predictable results).
  • Emergency testing.



  • Reduces time and costs.
  • Makes testing more extensive and exhaustive. Long, tedious tests can be performed accurately and repeatedly. And you can be absolutely sure that no results will be left unrecorded.
  • Improves precision. Automated test cases are standardized and more reliable.
  • Enhances test coverage.
  • Boosts developers’ confidence.


  • Before purchasing and implementing automation tools, make sure you have people, capable of operating them, with appropriate coding knowledge and skills. Don’t forget that automation tools are mere tools. In fact, the success of your testing process relies on how productively you can handle them. To see how you can involve your manual testers in automation process, read this article.
  • In addition to the initial setup cost and maintenance cost you will also have to pay for support, infrastructure and training. So before taking the decision make rigorous cost estimation and calculation to predict if this investment is going to bring you more gains or losses.
