Automation Testing Tools – How to Choose The Right One


Automation Testing Tools – How to Choose The Right One


Automation testing tools are applications that use automated test scripts to check function and/or non-function requirements.

As the Agile and DevOps manifesto has become the standard for software testing, it is important to set up a clear plan for evaluating automation testing tools. In the end, this plan will have to answer the following questions:

  1. What features are you looking for?
  2. Who’s going to use the tool for testing? Devs or QA teams?
  3. Can it be integrated with CI/CD pipelines or toolchains?
  4. Is it easy to maintain scripts and reuse test assets?
  5. What is your team’s budget?
  6. Where can you get support for technical issues?  

Plus, there isn’t a one-size-fits-all automation tool. It boils down to your team’s specific needs.

Choose the Best Automation Testing Tool for You

It is unnecessary to emphasize the importance of automation testing tools. Don’t choose one based solely on the success of other teams. Instead, choose the best-fit option based on your team’s specific needs, human resources, and future scalability.

If your testing team consists of experienced developers, using Selenium or Appium as an automation framework can be advantageous because it allows you to build and scale from the ground up.

However, if your team consists primarily of manual testers and requires a low-code solution that can also scale with the team’s future scalability, ready-made frameworks such as Katalon Studio can be an excellent choice.

It is simple to create, run, and maintain tests, as well as obtain centralized analytics of test results.
