How to Become a QA Tester

QA tester

Quality Assurance (QA) testing is a crucial part of software development, ensuring that applications meet the highest standards of functionality, usability, and performance. Becoming a QA tester requires a blend of technical skills, attention to detail, and a deep understanding of software development processes. In this comprehensive guide, we’ll walk through the steps and strategies to embark on a successful career as a QA tester.

What is QA Testing?

Defining QA Testing

QA testing involves evaluating software applications to identify bugs, defects, and areas for improvement. It’s a systematic process that ensures software products meet user expectations and perform as intended. QA testers play a vital role in the software development lifecycle by conducting various tests to detect issues before the product reaches end-users.

Importance of QA Testing

  1. Enhancing User Experience: QA testing helps deliver high-quality products that provide a seamless and satisfactory user experience.
  2. Ensuring Reliability: By identifying and fixing defects, QA testing enhances the reliability and stability of software applications.
  3. Maintaining Reputation: Quality software builds trust and credibility among users, contributing to a positive brand reputation.
  4. Cost Savings: Detecting and resolving issues early in the development process reduces the cost of fixing problems post-release.

Acquiring Basic Knowledge

Understanding Software Development

To excel as a QA tester, it’s essential to have a solid understanding of software development principles and methodologies. Familiarize yourself with concepts such as Agile, Waterfall, and DevOps to adapt to different project environments.

Learning Programming Languages

While not always mandatory, having knowledge of programming languages such as Python, Java, or JavaScript can be advantageous. It allows you to understand codebases, write automated tests, and collaborate effectively with developers.

Mastering Testing Techniques

Gain expertise in various testing techniques, including:

  • Functional Testing: Verifying the functionality of software features.
  • Regression Testing: Ensuring new updates don’t break existing functionalities.
  • Performance Testing: Evaluating software performance under different loads.
  • User Acceptance Testing (UAT): Validating software from an end-user perspective.

Developing Technical Skills

Learning Test Automation Tools

Familiarize yourself with popular test automation tools like Selenium, Appium, and JUnit. These tools streamline testing processes, improve efficiency, and enable continuous integration and delivery practices.

Understanding Bug Tracking Systems

Become proficient in bug tracking systems such as Jira, Bugzilla, or Trello. These platforms help track, prioritize, and resolve issues identified during testing.

Practicing Documentation

Effective documentation is crucial in QA testing. Practice creating comprehensive test plans, test cases, and bug reports to communicate findings clearly to stakeholders and development teams.

Practical Experience

Internships and Entry-Level Positions

Seek internships or entry-level positions in QA testing roles to gain hands-on experience. These opportunities allow you to apply theoretical knowledge in real-world scenarios, understand industry best practices, and build a professional network.

Freelance Projects and Side Hustles

Engage in freelance projects or side hustles to broaden your skill set and work on diverse software projects. Freelancing offers flexibility and exposes you to different testing challenges, enhancing your problem-solving abilities.

Contributing to Open Source Projects

Participate in open-source projects related to software testing. Collaborating with the open-source community not only hones your skills but also showcases your expertise to potential employers.


Pursuing QA Certifications

Consider obtaining certifications such as ISTQB (International Software Testing Qualifications Board) or ASTQB (American Software Testing Qualifications Board) certification. These credentials, along with specialized courses like those offered by QA Academy Novi Sad, validate your proficiency in QA testing principles and methodologies, boosting your credibility in the industry. 

Continuous Learning and Professional Development

Stay updated with the latest trends, tools, and techniques in QA testing through continuous learning. Attend workshops, webinars, and conferences, and actively engage in online forums and communities to expand your knowledge base.


Becoming a QA tester requires a combination of technical skills, practical experience, and a commitment to continuous learning. By acquiring basic knowledge, developing technical expertise, gaining practical experience, and obtaining relevant certifications, you can embark on a fulfilling career in QA testing. Remember, attention to detail, critical thinking, and effective communication are key attributes that contribute to success in this dynamic and rewarding field.
