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.

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

Super super super! But you can use autowired without creating contructor.

@KrisFoster1 3 года назад

That's a great point @MR. J, yes you can

@AmNotLegend 3 года назад

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?

@dusanristic4400 2 года назад

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.

@christianwulf8224 2 года назад

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.

@frankoppermann1877 2 года назад

Very nice video. How do you handle external service calls in acceptance tests. Are you using mocks or real calls?

@Das.Kleine.Krokodil 2 года назад

Why add a mock to the context? What will change if you use @Mock instead of @MockBean in the controller?

@bronxed3666 2 года назад

amazing. thank you

@brunosteffen8173 3 года назад

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?

@KrisFoster1 3 года назад

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!

@brunosteffen8173 3 года назад

@@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.

@KrisFoster1 3 года назад

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
