Watch our demonstration of effective unit testing
Finding bugs during development is 10x cheaper than fixing them in production. Unit tests catch issues immediately, when the context is fresh and fixes are simpler.
Unit tests act as a safety net, preventing new changes from breaking existing functionality and saving you hours of tedious debugging.
Writing testable code forces you to create modular, loosely coupled components with clear responsibilities – leading to better architecture and maintainability.
A robust test suite lets you refactor your code without fear – clean up technical debt, improve performance, and modernize your codebase with confidence.
Well-written tests document exactly how your code should work, simplifying onboarding and reducing knowledge silos across your team.
Unit tests form the backbone of CI/CD pipelines, automatically validating code changes so you can deploy with confidence and speed.
You're trying to track down a regression bug that could have been caught immediately with a test
Your team needs to onboard new developers who can quickly understand code behavior by reviewing tests
You need to refactor complex code without the fear of breaking existing functionality
You're implementing new features and need a safety net to ensure seamless integration with existing code
You want to avoid the exponentially higher cost of fixing bugs in production compared to catching them during development
“After going through all the lessons, I gained the necessary skills to perform well at my on-sites. I crushed even the DP problems, which were my biggest fear. And thanks to that I landed offers from Microsoft and Uber. Thank you AlgoCademy!”
Cristina Radulescu
Senior Software Engineer at Uber
“AlgoCademy really helped me improve my problem solving skills and write incredibly clean code. I was worried it wouldn’t be done in time for my coding interviews, but the way the curriculum is structured made me progress very quickly. Thanks for your work!”
Connor Holland
Software Engineer at Vanguard
“Wow. I’ve been using AlgoCademy for a while and now I can finally solve coding questions on my own. This gave me the confidence I needed for my interviews, and guess what? I landed the offer at Samsung! You guys truly kick ass. High fives!”

Yes! The content is designed to cover everything you might encounter when writing unit tests. We begin with the fundamentals and progress to advanced techniques that ensure your code is robust, reliable, and maintainable.
Beginners welcome! While we assume you have a basic understanding of programming, you don’t need any prior experience with unit testing. Our lessons guide you step by step toward proficiency.
No drip-feeding here! You get full access to every module right away. Jump in and start mastering unit testing immediately – plus enjoy regular updates as we expand the curriculum.
You don’t need expertise in any one language. Our focus is on the principles of effective unit testing, presented in a language-agnostic way so that you can apply the concepts to any programming environment.
Every day you delay means more time spent troubleshooting avoidable issues. Our course equips you with the ability to write tests that save you hours, reduce debugging hassles, and improve overall code quality – so why wait?
When you compare the cost of addressing bugs in production versus catching them early through unit tests, the benefits are clear. Robust unit testing cuts debugging time dramatically and builds confidence in your code – an investment that pays off over and over.
