At a minimum, testers should understand programming concepts, such as variables, loops, conditional statements, and functions. This knowledge is essential to grasp the code and allows testers to write simple scripts or perform basic debugging tasks. Additionally, testers should understand relevant scripting languages or tools used in their industry or workplace.
For example, knowledge of frequently used Python, Java, or JavaScript can be advantageous in test automation frameworks. Proficiency with scripting tools can also be beneficial in automating test cases. As a tester, you should strive to comprehend better the underlying architecture and technologies used in software to identify potential risk areas, understand integration points, and effectively design test cases.
However, there is no simple or concrete answer to the question: the depth of coding knowledge a tester should have varies based on the team’s structure, the software complexity, and specific goals. Most companies have dedicated automation engineers or developers who handle advanced coding tasks, while testers focus more on test case design, execution, and analysis. So the ideal coding knowledge for a tester lies in keeping the right balance between understanding the codebase and having the ability to write basic scripts or test automation scenarios.

Coding Roadmap for QA Testers
Not sure where to start with coding as a tester? Here is a straightforward path that takes you from zero to a level where you can contribute to automation and hold your own in technical conversations with developers.
Step 1: Learn the basics of Python. It is the most beginner-friendly language and the one most commonly recommended as the first step for programming for QA tester roles. Focus on variables, loops, conditionals, and functions. You do not need to go deep, but you need to be comfortable.
Step 2: Get familiar with HTML and CSS. If you do any web testing at all, understanding the structure of a web page makes you significantly better at identifying and reporting UI issues.
Step 3: Learn SQL basics. A large share of bugs live in data. Being able to write simple queries to check database states during testing is a practical skill that pays off quickly.
Step 4: Pick a testing framework. Selenium or Playwright for web, Appium for mobile. Start with whichever one matches the product you test.
Step 5: Build one small automation project from scratch. Even a basic login test that runs in a browser is enough to solidify everything you have learned.
Step 6: Connect your tests to a CI/CD pipeline using Jenkins or GitHub Actions. This is where your skills become genuinely useful to the team and visible to your manager.
Best Programming Languages for Software Testers
One of the most common questions software testers need to know about programming is where to actually start. The short answer is: it depends on your project, but some languages are far more useful for testers than others.
Python: The best first language for most testers. Easy to read, easy to write, and widely used in test automation with frameworks like Pytest and Robot Framework.
JavaScript: Essential if you work on web products. Used heavily with Playwright and Cypress, two of the most popular modern automation frameworks.
Java: Common in enterprise environments. If your team uses Selenium with Java, this is worth learning. More verbose than Python but well-documented.
SQL: Not a traditional programming language, but a must-have for any tester who touches data. Write simple SELECT queries and you will catch bugs others walk right past.
Ruby: Used in behaviour-driven testing with Cucumber. Relevant if your team follows a BDD approach.
Start with one. Get comfortable. Then expand.
