The Essential Skills Required For Automation Testing

Automation testing is no longer a "nice-to-have" skill in the modern software development lifecycle (SDLC)—it’s essential. However, for many aspiring automation testers, the path to mastering these skills can seem overwhelming. We tapped into our community of 90,000+ testers to uncover what are the essential skills every test automation tester should have. Here's what they revealed, and we're excited to pass it on to you! 
 

Automation isn’t just about learning tools; it’s about thinking strategically. A contributor to the Katalon community eloquently put it:  

“The difficult part when getting started in the world of test automation is understanding WHY I want to automate something. Then, with the scope clear, I put all my attention on the HOW I can automate.” 

- Gaston Marichal

This statement hits on a critical insight: automation begins with understanding the purpose, not just the process. With that in mind, let’s explore both the thinking and technical skills that will pave your way to success in automation testing. 
 

Technical Foundations: Master the Basics

At its core, automation requires a solid understanding of technical concepts. Here's where to begin: 

1. Basic Programming Knowledge: Even if you're using a no-code tool, understanding programming fundamentals is essential. One of the community members mentioned: "Beginners should start with a basic understanding of languages like Java or JavaScript. They should also get familiar with control structures like loops, conditional statements, and basic object-oriented principles for writing scalable scripts." 

• Start with small coding exercises in languages like Java or JavaScript. Platforms like Codecademy or free resources on GitHub offer simple projects that will introduce you to the logic and structure of these languages. 
   

2. Understanding Locators and Object Identification: In UI automation, creating robust locators is one of the most critical skills. Locators help you interact with the elements on a web page, such as buttons and text fields, which is fundamental in automated testing. 

• A Katalon Academy instructor highlighted: "Knowing how to create robust and efficient locators using XPath, CSS selectors, IDs, and attributes is key. This ensures your scripts can interact with web elements reliably across different builds."
• Spend time practicing how to inspect elements in a browser using developer tools. Write locators manually and test them on different pages to ensure they work reliably. 
   

3. Familiarity with Automation Tools: When it comes to tools, being comfortable with industry standards like Selenium or Tricentis or Katalon Studio will set a strong foundation. Being comfortable with the tool’s interface, functionality, and how it integrates into your team’s workflow is crucial. 

• Katalon Studio, in particular, is often lauded for its beginner-friendly interface while offering advanced features for seasoned testers.
• Start by automating simple test cases in any tool of your choice. Use tutorials and courses to guide you step-by-step through the tool, allowing you to build confidence in automating test cases quickly.

4. Get Comfortable with Version Control: Test automation is a collaborative effort, especially when working with large teams. Understanding how to manage your code and scripts in a team setting is key to long-term success. 

• Version Control Systems (VCS) like Git are non-negotiable for automation testers today. Knowing how to use a VCS is fundamental to managing test automation projects across multiple team members, ensuring everyone works on the latest version of the code and preventing conflicting changes.
• Create a GitHub account and store your automation scripts there. Learn how to commit changes, create branches, and resolve conflicts. This will prepare you for real-world collaboration in agile development environments.

Strategic Thinking Beyond The Tools

Automation isn’t just about technical expertise—it’s about why and how you approach automation in the first place. As a member noted, “Automation is like other testing activities; you need to find and configure some process within your testing lifecycle. Don’t let automation happen only in your free time. Make it an established activity.”  

This advice touches on the need to think strategically, to understand that automation testing is not a one-off task, but an ongoing process that needs clear goals and organization.  

1. Clear Objective Setting: One of the biggest challenges beginners face is knowing what to automate and why. Without clear goals, automation efforts can quickly become overwhelming and ineffective. 

• Gaston Marichal says "Many automation projects have failed due to the lack of clear objectives—such as the number of test cases to automate per cycle or the expected completion date. Automating everything is not feasible, and some test cases are not worth automating."
• The idea is to be selective with what you automate. Automation should save time, not create extra work.
• Apply the SMART goal framework to your automation efforts. Set Specific, Measurable, Achievable, Relevant, and Time-bound objectives. For example, automate 20% of your test cases within the first sprint and track progress over time. 
   

2. Maintaining Modular and Scalable Scripts: It’s easy to get excited about automating everything, but this can lead to unmanageable and redundant test scripts. As Ravikanth Edamakanti, a community member wisely advised: "Automation beginners should focus on building reusable and modular test cases to avoid redundancy."

• Building scripts that are modular not only makes maintenance easier but also ensures that your automation framework can grow with your testing needs.
• Start by organizing your test scripts into smaller, reusable components. For instance, create libraries for frequently used test steps like login procedures. This modular approach makes it easier to maintain scripts as the system under test evolves. 
   

3. Test Data Management and Debugging: A key technical skill that overlaps with strategic thinking is the ability to manage test data and troubleshoot effectively.

• Learning how to generate, manage, and clean up test data for automated tests ensures that scripts run independently and don’t fail due to data issues.
• Additionally, debugging is an essential skill for every automation engineer. Familiarize yourself with debugging tools, like those built into Katalon Studio, and practice running tests with different sets of data to ensure they function independently. 
   

The Bigger Picture: Automation as a Continuous Process 

One of the key takeaways from the community discussion amongst QA professionals is that automation isn’t just a technical process—it’s a strategic one.   

“Test automation should be a formal activity within the Testing Lifecycle. It should not be treated as a task to do in your spare time.”  

This highlights the need for a structured approach to automation. It’s not enough to automate one-off tasks. You must continuously track your progress and refine your processes.  

Regularly review your automation efforts by tracking key metrics, such as how many test cases are automated and how often they need maintenance. This will help you identify bottlenecks early and keep your automation strategy on track.

Conclusion: Building a Roadmap to Automation Success 

Mastering automation testing is about more than learning the latest tool or language—it’s about adopting a strategic mindset, defining clear goals, and developing a technical foundation that allows you to collaborate effectively in your team.  

Start with the basics, build strong programming skills, master locators, and familiarize yourself with test automation tools. Then, think bigger:

• How does automation fit into your testing lifecycle?
• What goals are you trying to achieve?
• How can you make automation work for you?

The key is to think both technically and strategically. Combine that with continuous learning, and automation testing will become not just a skill, but an asset to your career and team.  

So, are you ready to take the plunge into the world of automation? Follow this roadmap, and you’ll be well on your way to mastering the essential skills required for automation testing. This will surely define your success.
