Course Description
From this course, you can learn Testing for software engineers that includes the learning of JUnit 5, Mockito, PowerMock, and TDD approach.
- Open source code
We hide nothing from our students! Including the source code for the home task solutions and source code of examples that were shared during the lesson. Having the source code you can just copy and paste it to run it on your local computer to understand how things work better.
You are allowed to use all source code examples for learning purposes. This helps significantly to configure the environment and make tests work, especially in case students didn't work with any testing framework in the past.
- Q&A support
The significant difference between the online and offline learning process is the instructor's availability. If you are in one room with a tutor he always can help you to get understand the specific concept or to help fix your code on your computer.
In this course, we are supporting students with answers to any questions flagged in the Q&A section. In case there will be recurring questions - separate video lessons will be created to show how to address the issue.
So with this course you are not just getting video materials, code exercises, source code, access to the free mobile application without limits (which is still pretty cool, huh? :) ), but you also get tutor support and answers to your questions along with this course.
- Relevant knowledge
After our team investigated other Java courses on Udemy we realized that most of them have nothing in common with real life. The information which is shared there is very old and significantly out of date. For example, the instructor teaches a framework which is not been used already for 15 years. Or instructors do stress on the programming design which is not used anymore at all!
The instructor of this course is a consultant in a top-rated IT outsourcing company and helps to bring cutting-edge solutions in IT for all his clients. Feel free to check the LinkedIn page of the instructor and check skills endorsement. More than 19 thousand people across all over the world (BTW most of them are from the top 100 companies of the world) evaluated the skills of Andrii Piatakha.
With this course, you can be sure that you will spend your time learning the right things from one of the best IT consultants in the world.
- Free mobile App without limits for our students
Knowing Java is one skill. Be able to pass interviews in the company - that is another skill :) Nowadays a lot of companies use tests to select candidates on the first level of interview. We developed applications to practice skills specifically for such purposes.
In this course, we will provide you link to download our FREE mobile app for android. (soon it will be also available for iOS platforms)
The instructor of this course comes up with hundreds of tests that are used to test the knowledge of candidates. With this application, you will be well-prepared for the interview.
Also, only for our students - there is no limit on attempts to pass certification. In the course, we will tell you how to set up a special bonus code that will remove restrictions for our students inside the app.
- High concentration of useful material in each lesson
Sometimes you can notice that watching 5 minutes of our lesson is equivalent to watching another 30 minutes lesson.
This is because time spent for preparation for the lesson (script for the lesson, lesson structure) and video editing (to cut boring pieces of the lesson or time when the program loads) sometimes 10 times as much (sometimes even 20) as the final lesson duration after video editing.
Also, each topic is separated from another. In case some concept will be explained in the next lesson and you don't need to worry about understanding this in the scope of this lesson - the instructor will make an announcement when a specific topic will be covered.
Go and try it yourself! We will appreciate your feedback.

I was hoping for a bit more depth. Maybe you should label the course 'for beginners' or 'overview'. The course is well done but did not meet my expectations.
By Nazmul Hossain on 9/15/2023
The course materials are well-structured and provide a good introduction to JUnit 5, Mockito, PowerMock, TDD, BDD, and ATDD. The explanations are clear in the written materials, and the code examples are helpful in understanding the concepts. However, the trainer's spoken explanations during video lectures are often incomprehensible due to poor English pronunciation. Understanding the trainer's instructions and explanations is crucial in a technical course like this one, and unfortunately, the pronunciation issues make it difficult to follow along. This becomes especially problematic when trying to grasp complex coding concepts and testing frameworks. I found myself frequently rewinding the videos and turning to supplementary resources to compensate for the lack of clarity in the trainer's speech.

I needed a refresher on unit testing practice, and this course proved to be the right thing.
By Denys Malik on 1/15/2022
Great course. It is well-structured and has a big amount of practice. I've got a lot of useful info from it. Thank you.
By Irfan Dogic on 12/3/2021
Very good presentation of JUnit and Mockito. I was expecting more "real" examples and not classes with single method where the tests are obvious.
By Alba Ramos Pedroviejo on 10/9/2021
Complete and practical course covering many aspects of TDD. The instructor is very clear in his explanations, I really enjoyed the course!
By Angella Mabwe on 9/14/2021
The teacher is amazingly good. I only have some challenges with his accent and I hope I will get used as I progress
By Mikyas Tesfamichael on 8/2/2021
I would like to thank you very much for this high quality course Andrii. The detail with which you describe the material is very attracting. Keep up the great work.
By MrX X on 6/28/2021
Other courses I took on Udemy were poor so I came to this one with low expectations. I was blown apart by the level of detail and how thorough it is. You can tell Andrii really cares about delivering quality, and he does. Only complaint would be that his English is hard sometimes to understand but it's a minor thing. 5 stars no doubt.

This course is a great course. The instructor is very professional. I love this course and instructor.
