42. Best Practices for Test Automation

1. Establish a test automation plan

Put your AUT and testing teams under a scope and dissect them. Teams should define the automation scope and testing priorities while evaluating the available resources and potential risks. After the assessment, the team can determine a course of action with a specific timeframe and division of work.


  • Plan for test automation as soon as possible. Test automation requires various machines and software, which can cause a bottleneck if it needs time and resource allocation.
  • Not all test cases can be automated. Test cases should be automated with clear pass/fail results, time-consuming tests, a high risk of failure, or stable features.

2. Choose a test automation approach

Selecting the right tools is important for smooth test execution and maintenance. Teams can select between 5 kinds of automation frameworks: modular-based, linear, library architecture, data-driven, and hybrid frameworks.


  • Perform risk analysis on the project. Recommended parameters include descriptions of potential risks, affectability, probability, mitigation, and associating costs.
  • Review test artifacts with development. As business priorities change over time, testers should ensure test planning aligns with designed functionality.

3. Acquire a testing tool

The testing team now has various tools available to fit each use case. Teams should develop an automation tool strategy with extensive questions about available resources and requirements.


  • Don’t rush going with the “best” automation testing tool in the industry. See which test automation framework you need to configure, then select a few software that possesses the key functionalities of your application.
  • If you have the expertise, stick to Selenium if you’re doing Web Testing and Appium for Mobile test. They produce the most robust tests and are adaptive to most languages, platforms, and OS.

4. Set up an automation environment

Check your testing environment and acquire the required automation tools for your automation test.


  • To ensure consistency, the development and test environment should be identical to the stage environment, whereas the stage environment should be the same as the production environment.
  • Consider data as part of your test case, like the location to sort data, should the data be masked, and what happens to the data after testing.

5. Design test automation

The test build should be parallel to software development to stay on track with app altercation. When designing test cases, remember to follow the right order of testing modules and cover both the positive flow (normal flow) and negative flow (covers unauthentic attempts to enter into the software or any invalid data to flow across the application).


  • Adopt Behavioral-Driven Development if possible.
  • Data-drive your test for reusability.
  • Before adding any test into a regression suit, make sure to run and verify it multiple times to ensure that specific test’s quality.

6. Execute test automation

You can use pipelines to increase the speed of your release while maintaining quality, such as DevOps and CI/CD. Notice: some testing environments need a prior setup like local, offline, CI/CD, etc.


  • Parallelize the automated test cases that require no interdependency to save time.
  • Use a pipeline orchestrator or a scheduling tool to execute test cases in parallel.
  • Put the application through tests under stable servers and network connections. Avoid unexpected failures and elements that eat time.

7. Result, Analysis, and Reusability

Have a plan to analyze failing test cases and the follow-up actions to fix detected problems. Testers will take a longer time than anticipated to be notified and fix the bugs.


  • Identify slow, failing tests. Add a timer into your test run to single out tests that continuously fail or take time. This practice helps you identify the bottleneck and reconfigure these test activities, maximizing your testing efficiency.
  • Compare test outcomes to validated reports and documentation from previous versions to expand coverage.
  • Incorporate either in-tool or third-party smart test reports function for advanced test reports and better test maintenance. Katalon TestOps is a recommended option for those who want a smart and serverless solution
