Learn JUNIT5


  • Java basics


This is a short course that will help you understand better what is JUNIT and ho to test your application in a way that you can find bugs.

If you like this presentation, you can find more written tutorials on my website, or you can buy the other course about testing a java app. If you really want one of my courses and you don't have the material possibility to buy it, you can send me a message and I will give you a free pass.

You will learn about :

  • JUNIT concepts - we first write the code for our app, then we identify what is missing to be proud of our code and at the end of this chapter we implement some tests that will cover all our functionality.

  • how to use POSTMAN to write automated tests and also build your own mock server. POSTMAN is used, most of the times, just for making requests to our app, but in reality it has a lot of functionality that can make your life easier

  • Mockito - we will talk about stubs/spies/mocks. We first write some tests that will use stub/mock/spy for the simple java app and after that we learn what changes in our approach. You will need this information to know exactly when to use what.

  • Wiremock - you will learn how to an app that uses a rest api client

The entire project can be downloaded at the end of the course.

Who this course is for:

  • middle java developers
  • beginner java developers

Passionate about software engineering in general with proven experience in top companies. Worked with as many programming languages and technologies as I could during my job and outside of my job. This curiosity brought me to the conclusion that even if people think that programming languages are so different, they are not, and it's your "engineering" mind that you should build.

I am a strong believer of the fact that anyone can learn anything, if they have enough motivation.

Tried to bring my best in my courses, explaining concepts as better and short as possible, with meaningful diagrams.

If you choose to take my course, I would love to have your constructive reviews (what should I improve/what topics you would like to see more from) and hopefully some positive ones too.
