What is automated testing?
The larger apps get, the more time consuming it also gets to manually verify that everything works as expected and that a new feature didn’t break an older part of the code. Instead of manually testing your apps, you can write code that verifies the correctness of your app with a single click. The most harmful belief is that you don’t have time to write tests. It’s the opposite – we write tests to save time, since they save us countless of hours we’d otherwise spend hunting bugs.
Learn Automated Testing in the Real World
1. Stop wasting time with courses that only teach you the basics
This is not another “test adding two numbers” kind of course. In this course, you’ll be applying industry practices for the open-source app Ivy Wallet with over 50,000 lines of code.
2. Build apps faster and more confidently
A common thought of app development beginners is that writing tests will slow them down. In fact, the opposite is the case. Knowing how to correctly write automated test cases will save you all the time you would otherwise spend debugging.
3. Learn industry practices from an industry professional
This course is the result of 12 years of development experience packaged into digestible modules. After following through the 12 parts, you’ll have the testing skills needed for a job at a top company.
Philipp Lackner has over 14 years of experience in the software field. Over the past years, he built a following of over 250,000 developers on social media who trust his work. With over 25,000 sold copies of his courses and 1,000h+ spent for teaching Android concepts, he already helped hundreds of thousands people to learn practical skills they can immediately apply.
He has a degree in computer science, however it didn’t go as expected. The amount of theory that was taught in university made him think about a better approach to learn what is really needed in the real world. Over time, Philipp found mentors who taught him exactly that in a practical setting. That was the game changer for his career.
After having worked for dozens of companies around the globe as a consultant, Philipp now wants to teach other Kotlin developers what really counts for becoming an outstanding developer in today’s competitive industry.

While most other testing courses out there barely touch practice, this course puts the focus on exactly that. It doesn’t help you to learn theoretical concepts, if you don’t know how to apply them in your own projects or at your workplace.In this course, you will still start with simple examples, but learning doesn’t stop there – instead you will also work on a large production open-source app called Ivy Wallet and write efficient test cases for it. That way, you directly practice what matters in the real world.
