If you want to get into test automation, learning Selenium, Playwright, Cucumber, Rest Assured or Serenity BDD is only part of the journey.

At some point, you need to understand the code.

Many testers start by copying snippets from tutorials, Stack Overflow, GitHub, or AI tools. That can work for a while. But when the code breaks, when you need to change it, or when your framework becomes more complex, copy-paste programming quickly becomes frustrating.

This course helps you build the practical Java foundations you need to become more confident with test automation code.

You will not learn abstract computer science theory. You will not spend hours on topics you rarely use in real automation work. Instead, you will focus on the Java skills that testers, QA engineers, and automation engineers use every day.

What you’ll learn

By the end of this course, you will be able to:

• Read and understand Java code used in test automation projects

• Write cleaner, more maintainable Java code yourself

• Use variables, methods, classes, objects, and interfaces with confidence

• Work with collections such as Lists, Sets, and Maps to manage test data

• Use assertions to check expected outcomes clearly and effectively

• Handle exceptions and errors in a more robust way

• Understand object-oriented programming in a practical testing context

• Use modern Java features such as lambdas, streams, and records where they make sense

• Write and structure unit tests with JUnit

• Build confidence through hands-on coding exercises and katas

  
  

Why this course is different

Most Java courses are designed for people who want to become software developers.

This course is different.

It is designed specifically for testers and QA professionals who want to move into test automation or become more effective in their current automation work.

That means the examples, exercises, and explanations are focused on the kinds of coding problems testers actually face: working with test data, structuring test code, writing assertions, understanding application behaviour, and building code that is easier to change.

The goal is not to turn you into a full-time Java developer.

The goal is to help you become comfortable and capable with Java in a test automation context.

How you’ll learn

This is a practical, hands-on course.

For most of the course, you will use in-browser coding exercises, so you can start practising Java straight away without installing an IDE, setting up a project, or fighting with your development environment.

That means you can focus on learning the language and building confidence from the very beginning.

Later in the course, when you move on to the larger projects, you will work with more realistic Java project setups. By that point, you’ll already have the core coding skills you need, so the tooling will feel much less intimidating.

You will build your skills through carefully designed exercises and coding katas, including:

• The String Calculator kata

• A complete shop application

• A speaking clock challenge

• Practical examples inspired by real test automation problems

You will also be introduced to test-driven development ideas, because good automation code is still code — and code is easier to write when you have fast feedback.

But don’t worry: this is not an advanced TDD course, and you do not need prior programming experience.

Everything is explained step by step.

This course is perfect for

This course is for you if:

• You are a manual tester who wants to move into test automation

• You are a QA engineer who wants stronger Java coding skills

• You have copied automation code before but struggled to adapt or debug it

• You want to understand what is happening inside Java-based automation frameworks

• You are preparing to learn Selenium, Playwright, Cucumber, Rest Assured, or Serenity BDD with Java

• You want a practical, tester-focused introduction to Java
  

This course is not for

This course is probably not for you if:

• You are already an experienced Java developer

• You are looking for a complete academic Java reference course

• You want a Selenium or Playwright tutorial specifically

• You want advanced Java topics that are not commonly used in test automation

If you want to learn Selenium, Playwright, Cucumber, Rest Assured or Serenity BDD, this course gives you the Java foundation that will make those tools much easier to learn.

Why Java still matters for test automation — especially with AI

Java is still one of the most widely used languages in enterprise test automation.

Many popular automation tools and frameworks use Java, including Selenium, Cucumber, Rest Assured, JUnit, Serenity BDD, and many in-house enterprise testing frameworks.

And with AI coding tools becoming more common, understanding Java is becoming even more important, not less.

AI can help you generate code faster. But it can also generate code that is overcomplicated, fragile, misleading, or simply wrong. If you do not understand the Java behind the code, it is very hard to know whether the AI has helped you — or quietly introduced a problem you will have to fix later.

This course helps you build the foundations you need to use AI coding tools more effectively. You will be better placed to review generated code, spot mistakes, ask better prompts, refactor poor suggestions, and adapt the code to your own automation framework.

There is also a bonus module coming soon that introduces practical AI-assisted coding for test automation, showing how AI can support your work without replacing the need for clear thinking and solid coding skills.

The goal is not just to write Java code.

The goal is to understand the code well enough to use modern tools, including AI, with confidence and judgement.

Start writing Java code you actually understand

By the end of this course, you will be more confident reading, writing, debugging, and maintaining Java code for test automation.

You will understand what the code is doing, why it is written that way, and how to change it when your tests need to evolve.

If you are ready to move beyond copy-paste coding and build real confidence with Java, this course is for you.
