- In this video we will be testing a Spring REST controller. We will be writing a full test suite with unit tests, integration tests & acceptance tests. We will be using JUnit5, Mockito, MockMvc & more. We will also be discussing the purpose of each type of test with their advantages & disadvantages.

Spring Initialiser: start.spring.io/
Unit testing starts: 1:40
Integration testing starts: 11:25
Acceptance testing starts: 21:50

No more hours of scouring the Internet, this here is the good deal. Thanks!
Glad you enjoyed!
This is the clearest video i've seen on this topic. Thanks for the tutorial, was really helpful.
Sincerely brother thanks for taking the time to make this tutorial its very clear and straight forward much love and appreciation from Tanzania
5 min in and the video is way way more valuable than an entire series of some other youtubers that I wont name. I am an experienced programmer working with different languages and learning now java, but I can recognise who is really a developer and who is just a youtuber influencer with not real experience but the RGB keyboard and few screen unfortunally makes it look like they do. I can tell you are a real seasoned developer ! Either way thanks for these videos
This video gave me a confidence to do unit and integration testing in my project. Thanks for this very neat and clear explanation
Glad you enjoyed, thank you!
Best tutorial out there about Testing. Thank you!
You are a very good teacher. And I've seen a lot of teachers. Amazing job!
Amazing video!! Thank you so much...clearly explains the difference between all 3 tests.
Best spring boot test video! Thanks for share this.
The best testing tutorial I've seen ever, congrats and ty
Great Video, short but complete!
your explanation is very clear and simple, I like it, please do more videos about spring boot integration and unit testing ✨
Thank you for the feedback!
Man, it is awesome! I have been looking for your way of simple explanation of difficult thighs for two weeks) And finally it becomes clear for me. Thanx!!!
Your video is the best!!!
Thank you @Dimon, glad you enjoyed!
I wanna say thank you for the crystal clear explanation.
Good stuff, very useful.
Thank you so much! You've explained it so clearly and it was easy to understand!
Kris Foster always delivers good, quality and relevant content, thanks man!
Great content. Thanks for the lesson bro! I'm migrating the backend of a project from PHP to Java, those tips really helped me.
That was super helpful as a new tester 👌 thank you man 💪
Great tutorial, keep up with the good work! 😉
Amazing video. Thank you so much. Been looking for this for some time.
Simple and easy explanation.
Super super super! But you can use autowired without creating contructor.
That's a great point @MR. J, yes you can
Thank you very much for the content ☺️
is @MvcTest not a Unit test? you mocked its dependencies. for the acceptance test, is it good to use Rest-Template to simulate invoking API from a client side?
It's not necessarily; you still have an integration between the actual HTTP Request and the Controller that handles the request. The rest is mocked to narrow the test (make it cheaper).
As they are cheaper than Acceptance Tests, I find them useful to test error scenarios such as 403, 404, 400 or any other business/validation logic that might be returned by the controller.
I agree with you. It is a unit test, too. I would never call it an integration test. It does not integrate any two or more classes of the application.
Thanks man your content really helped me, cheers! Keep up with the good work
Liking and subscribing + notification THANK YOU!

Very helpful, thanks!
Thank you. Excellent tutorial!
Thank you, It is very helpful.
Thank you, this was very clear
Thank you so much! This helped me tremendously.
Muchas gracias por el tutorial! Very thanks, was helpful!
Thanks for sharing! this video really useful
just brilliant. respeKt !
Very good video! Thank you!
Thank you for the feedback!
amazing. thank you
Hi! Could you tell what keyboard you're using? Some mechanical one? Sound is amazing:)
Very nice video. How do you handle external service calls in acceptance tests. Are you using mocks or real calls?
Awesome!
Why add a mock to the context? What will change if you use @Mock instead of @MockBean in the controller?
Very informative
Very clear,Thanks
Thanks!
Hey,
cool Tutorial!
Can you also work those with Springsecurity?
I can't do the acceptance test without my credentials. My tests would even need to get data based on who is logged in... Can you still test those?
Hi @Bruno Steffen, thank you for your comment! Things get a bit more complicated once spring security is added to the equation. There are a few different approaches I can think of that you could take:
1. turn off spring security for the test. You could create a new spring security configuration that basically disables security for your endpoints. You could then use this configuration for your test. Here's a stackoverflow discussion where they're talking about how to do that stackoverflow.com/questions/23894010/spring-boot-security-disable-security.
2. create a mock user before the test & authenticate as this user for your tests. This is probably a bit more complex but I think for acceptance tests this would be preferred because in the end, you want to make sure everything is working correctly.
Sorry this answer probably doesn't tell you much more than you already know. Good luck!
@@KrisFoster1 On a different note, can you run the springboot application without running the tests? all i could find were people saying you would need to skip plugins in the maven lifecycle... I thought if you run the application in your IDE, the maven lifecycle doesnt even get triggered.
Yes if you run the application in from your ide or with mvn spring-boot:run from the command line the tests don't run. If you're using mvn compile /mvn package then they will
Spring Security series pls!
For some reason, an integration test execution was faster for me than simple unit test...
controller call is not happening
Very Good tutorial, but the MockMVC code is ugly & confusing
Short and concise, awful dude.
Best tutorial out there about Testing. Thank you!
