How to Become an Automation Tester: The Ultimate Guide to Start Your Career in QA

The author of this article is tech expert Pieter Murphy.

So, you want to become a QA automation tester? How do you go about getting on a suitable quality assurance career path? This brief guide looks at what you need to know when entering this industry.

According to a survey by Mordor, the automation testing market is expected to grow from $27.65 billion in 2023 to about $58.16 billion by 2028 (CAGR of 16.03%).

Automation testing is an in-demand skill at the moment, with a few paradigm shifts to consider.

To ensure smooth customer experiences, automation testing demand has risen, fueled by automated testing, the adoption of the DevOps model, which incorporates testing within the production environments instead of handing it off to Ops, and a shortage of skilled individuals to handle automation testing.

Let’s dive in and discover what the market offers and what to expect when you become a QA automation engineer.

Automation vs. Manual Testing

Manual testing has been the norm for a long time, so we should start with defining it and automated testing to see the difference.

Manual testing is testing a software application by manually running tests without scripts or automated tools. Manual testing lets testers dig into the software and find defects that automated tests may sometimes miss.

Manual testing is useful when human input is required, such as evaluating a user interface, usability, or user experience. However, it can be time-consuming, prone to human mistakes, and challenging to scale for complex projects.

Automation testing calls for using automation tools or frameworks to conduct expansive and comprehensive tests and improve speed, efficiency, accuracy, and coverage, especially in repetitive tasks, regression testing, and complex scenarios.

It is also a great way to cut down on the cost and effort of testing in the long run.

Skills Required to Become a QA Automation Tester

To become a good automation tester, you must acquire a skill set that includes complex/technical skills and soft skills for the non-technical portion of your work.

skills needed for a QA automation engineer

Let’s dive and learn what they are.

Hard Skills

Hard skills include the subject matter you must go through or be proficient in to become an expert in automation testing.

They include:

Programming Languages

Becoming a QA automation engineer requires proficiency in at least one programming language, including C#, Java, Ruby, Python, or JavaScript. The languages are used to write test scripts, interact with the app during tests, and automate test cases.

To become a QA tester, you must leverage programming languages across libraries, frameworks, and tools that facilitate automation testing, and mastering them is therefore crucial.

Basics of Software Development and Testing

Understanding the software development lifecycle, software testing lifecycle, and software testing methodologies (Agile, Waterfall, or DevOps) is essential.

Along with that, beef up your knowledge of software testing fundamentals, including test types, test design techniques, test levels, test execution, defect management, design techniques, and test reporting.

The skills help plan, design, implement, execute, and maintain effective and efficient tests when you become an automation testing engineer.

Basics of Test Case Design and Bug Reporting

As a tester, you must know how to design test cases covering the functional and non-functional requirements of the apps under test. You should be able to write clear, accurate, and concise bug reports detailing the defects found during testing.

This skillset helps you become a QA engineer who can assess the quality and reliability of the application under testing and provide actionable feedback to stakeholders and developers. 

Concepts in Automation Testing

To become an automation software tester, you must understand the concepts and principles of automation testing, including the process, best practices, tools, frameworks, and challenges.

You also need to be proficient at selecting the appropriate test cases for automation, designing and implementing automation test scripts, executing and debugging them, and maintaining and updating them.

Knowledge of Database and SQL

A QA automation tester must know how to use databases and SQL queries. Databases are used to store, retrieve, and manipulate data for the application being tested. SQL queries allow you to perform various operations on data, including update, insert, select, delete, join, etc.

These skills help verify the data integrity and consistency of the application being tested and perform database testing.

Knowledge of Linux Commands

To become an expert automation tester, you must know how to use Linux commands and shell scripts to perform tasks such as process management, network management, directory operations, system administration, etc.

Shell scripts are useful for automating and executing a series of Linux commands that help you work with Linux-based applications and environments.

Soft Skills

Soft skills encompass the non-technical skills you need to become a test automation expert and perform your tasks efficiently and effectively.

As we assert in our automation tester roadmap, the following core soft skills are essential:


Communication skills help you express yourself clearly and concisely, verbally and in writing, to different people. Communication abilities also involve listening actively, providing helpful feedback, and asking relevant questions.

As a tester, you must communicate with developers, project managers, business analysts, and customers to understand what is needed, report defects, and suggest improvements.


To become an automated tester, you should effectively communicate with team members while working towards the same goal.

In the world of DevOps and more modern methodologies of development, this often means working alongside them and testing the software as it is developing, with constructive feedback to make it all go smoothly.

Analytical and problem-solving

A QA automation tester needs to think logically and critically, identify and analyze the issues present, and find and implement solutions.

These abilities are essential for tasks such as data analysis, root cause analysis, debugging, and decision-making to support problem-solving.

Learning and adaptability

You should be able to continuously learn new things and adapt to different environments and situations. To become a master in automation testing, you learn to work with different kinds of operating systems, environments, devices, and so on.

You also have to use various tools, including the latest technologies, trends, and tools, a requirement that individuals who can learn and adapt easily possess.

Creativity and innovation

You should be able to generate and apply new and original ideas to improve existing processes and products. The ability also enables thinking outside the box, experimentation, and exploration to challenge conventions and assumptions.

How to Learn Automation Testing

You can use various resources to learn and study how to become a test automation expert. These will teach you the technical side of automation testing and give you the appropriate background to learn new things and perform your tasks effectively and efficiently.

Educational Background

There is no definitive answer to what educational background you need to get into automation testing or start learning it. However, some qualifications give you the background of what you will interact with. They include a bachelor’s degree in computer science, software, engineering, or a related field.

This gives you some programming, software development, and testing principles knowledge.

You also need good knowledge of the programming languages we’ve mentioned, as it is needed to write, modify, and debug test scripts and leverage them to interact with tools and frameworks.
