1. What is automated testing?

Automated testing is the use of software to support or perform test activities. This technique can significantly mitigate human time and effort over repetitive testing.

2. What are the advantages of automated testing over manual testing?

When compared to manual testing, here are the main advantages of automated testing:

  • Faster test execution speed
  • Reducing a lot of time and resources for repetitive tests
  • Higher test coverage
  • Better accuracy of test executions and results

On the other hand, the challenges of automated testing might include time-consuming setup, automation skills, coding, debugging, and maintenance efforts.

3. When should I go for automated testing?

The initial cost and setup of test automation can be huge. So, it’s necessary for you to evaluate whether it’s worth the effort.

That said, below are some of the most ideal cases when test automation could be your best bet:

  • In an Agile environment where continuous testing activity is required

  • At the end of a sprint or a release cycle

  • When there are multiple configuration options available in your software

  • When concurrency, load, and endurance of the software need to be tested

  • Automation of security tests against threats and attacks is needed

4. What should I consider when choosing a test automation tool?

There are tons of options on the market for test automation tools, both open-source and commercial.

When choosing the best-fit one(s) for your team, here are some great questions to take into account:

  • Do you or team members have enough experience and skills to utilize it?
  • What’s your budget?
  • What functionalities are you seeking for your team’s projects?
  • How well can it be integrated into your existing pipelines and toolchains?
  • How difficult is it to reuse and maintain test scripts?
  • How easy is it to get support for technical issues?

Let’s have an example. Your team is smally and has only manual testers without much coding experience. Your projects are mainly web testing. Katalon can be a good choice.

You can use the Record and Playback features for free to immediately start automating simple UI regression tests and working with test objects. As your team members get better at programming, they can start using built-in keywords or scripting in Katalon to create more test cases.

To see how to use Record and Playback, watch this course for the detailed steps.

5. What are the steps to move from manual to automated testing?

To help you know which direction to go and start, we suggest the following steps:

  • Find and decide the tests to automate (regression tests are the number one candidate)
  • Choose the compatible tools or frameworks (low-code tools would be the best if you lack programming skills)
  • Develop a strategy or process for tool usage
  • Start exploring, designing, executing, and maintaining automated tests
  • Monitor the effectiveness and impact of your automation solution
