- Ever looked for a comprehensive intro to JUnit 5 that is fun and entertaining at the same time? Then have a look at this brand-new episode of "Marco Codes": JUnit 5 Tutorial [Crash Course].
In this video, you'll learn how to use JUnit 5 like a professional. Understand what Maven/Gradle dependencies you'll need, how to write tests, how to use other assertion libraries like AssertJ and asserting JSON & XML, and explore new JUnit 5 features like @ParameterizedTests, @TestFactorys, and @ExtendWith. By the end of the tutorial, there won't be many questions left when it comes to JUnit 5.

i like the way you said "and thats all for the boring tasks", thank you for the amazing course by the way🔥
You explain the concepts very well, I hope you will continue to create more tutorials on topics like these
Content is so qualified. Love to see more on testing 🙂
So glad I found your channel, high quality content, compared to other channels I've seen it has so much depth. Thank you!!!
Fantastic work Marco Codes
I've started being confident with Unit Tests, thanks!
I learned a lot of things from you Mr. Marco Behler! I also follow your other channel, which also has some very good tutorials! Thank you! I wish you a lot of subscribers and likes because you're doing a great job!
You’re a fantastic instructor!
Hey, Marco! Thank you for the great content! Your explanations are clear and quite sufficient. Plus you demonstrate all things using modern IDE and library versions. Super cool! I would really like to see your video about testing in general: unit vs integration tests, what is a test case, edge case, how many tests to write, what to cover with tests and what not to cover... maybe some short insight into CI/CD - how to run tests, see results, coverage... There are almost no good videos on youtube summarizing all these.
Marco you are really explain all topics so clearly. Good luck we all love your articles and videos ;)
amazing video, thank you
i like your way of explaination...just to the point...nothing else and not too much empty talking..thank u and good luck
Thank you!
I'm visibly confused on what to test rather than how to test lol , anyway, can't wait to see the upcomming unit/integration test videos!
"If you want to be passive aggressive, you can do this..." this line cracks me up, LMAO
Awesome tutorial
What is the amazing content! I find your videos extremely useful. Why? You give a nice look around. For example, during learning Spring JDBC Template library, I got to know about what is connection pooling. And I really appreciate your video content.
Thnx, Marco!
Thank you for those nice words, Bogdan! Happy you're enjoying it.
Awesome!
Fantastic presentation - rare to see a white screen demo these days which to me works better for demos
a video about integration tests would be amazing :) and as an extra an integration test from api endpoint, consuming from kafka and saving in a db :)))
Great! keep it up :)
Good content 🙂
Beautiful content. Google has just suggested me your Gradle video. Coooool! I was looking for it for several days. Let me go watching!
PS: Marco, could you also make video about Mockito? It would be niiiice.)
Mockito is actually in the backlog, I'll see what I can do :)
Suddenly I like testing again 😂
Man, thank god for Spock
First to comment for the first time in my life. I have now completed one of my life goals 🚀
I love the spirit @Kevin :) !
@@MarcoCodes I hope you will do many more Java videos. I just landed my first backend job with not a lot of experience. So need to learn a lot.
8:28 expected should be the first parameter of the assertEquals method. I often make the same error. 😀
Ha, good catch!
1:51 Strangely, IDEA did not add test even though you told it the scope you wanted in the dependency manager.
Very good catch, didn't even notice that! Seems like a bug, because I just tried it out and it worked, interesting. Thank you!
hey nice video I did just subscribe. nice content. A docker video would be nice maybe using docker desktop :)
Anything specific you'd like to see covered in that video?
Very impatient to see a Quarkus tutorial from you.
Unfortunately not coming anytime soon.
you should show full code of class like User
Ok
Interesting it did not run setup/cleanup for the dynamic tests.
Yup, good catch! You might want to read the "Dynamic Test Lifecycle" section here in the documentation: junit.org/junit5/docs/snapshot/user-guide/#writing-tests-dynamic-tests
Hi please use the Wind Muff for you Audio Microphone. you voice is very clear and loud but the wind noise from your voice is not good.
Any specific locations in the video where that happens?
@@MarcoCodes at the start "junit junit" the song and "test of test" at the intro end at the "quick caveat" and also at many place when you come close to the microphone. or place your microphone at the TOP. czcams.com/video/arCe4UNwwYg/video.html
Homogeneous- the g is pronounced as j.
Thanks!
