How to Become a Successful QA Automation Tester?

The job responsibilities of an Automation Tester aren’t just limited to deducting errors while executing automation test scripts. It’s a lot more than that. 

When you are an Automation Tester, you have to write test scripts, design automation tests, choose the appropriate test automation tool, perform software testing to deduct defects and produce a result report. Let us see how to become one!

1. Master the Fundamentals of Manual Testing

Before diving into automation, it’s crucial to have a solid understanding of manual testing. This helps you grasp fundamental testing concepts, including test cases, test scenarios, and defect management.

Why is manual testing important? Because even the best automation scripts won’t be useful if you don’t know what to test! Manual testing experience will provide a foundation for designing effective test automation strategies.

Where to Start?

• Learn Software Testing Life Cycle (STLC) and Software Development Life Cycle (SDLC)
• Understand different types of testing like functional, regression, unit, and integration testing
• Practice using bug-tracking tools like JIRA, Bugzilla, and TestRail

2. Learn a Programming Language

Since automation testing involves writing scripts, you’ll need to get comfortable with coding. The most popular programming languages for automation testing are:

• Java (most widely used with Selenium)
• Python (simple and beginner-friendly)
• JavaScript (popular for web-based automation)
• C# (used in .NET environments)

Choose one language and become proficient in it. You don’t need to be a software developer, but you should be able to write, debug, and maintain test scripts.

Pro Tip:

Start with basic programming concepts like variables, loops, functions, and object-oriented programming (OOP) before jumping into automation frameworks.

3. Get Hands-on with Automation Tools & Frameworks

Once you’re comfortable with programming, the next step is to learn automation tools. The choice of tool depends on the type of application you’re testing:

Popular Automation Testing Tools:
