Testing Spring Boot Applications - Phil Webb

Recorded at SpringOne Platform 2016.
In this talk we'll cover the host of new features that have been added to Spring Boot 1.4 to help with testing. We'll discuss how to unit test your code, how (and when) to involve Spring in your tests, and talk about the various tools and libraries that you should be using. Taking a simple application, we're going to add: - Unit tests for basic components - Integration Tests for JPA entities and queries - Tests for JSON marshalling and unmarshalling - Tests for Spring MVC controllers - Tests for remote RestTemplate calls (using mocking) - End-to-end integration tests (hitting a real HTTP endpoint) Well also look a little bit at the internals of Spring's testing support and pick apart how the magic actually works.

Very well-done presentation that gets you started in testing Spring Boot apps!

I ported all my unit tests to Cucumber for readability purposes last night (single person project, it's nice that I can look at feature files and see what my components were meant to do at a glance). I think I need to libratize some of my code because the security convenience annotations just flat out didn't work. Still having some trouble with post methods as well, but still muddling through why that is, tried turning off CSRF and I was still having issues.

I have written a service layer which will throw UserExistsException, My RestController will call that service, but how to propogate the exception to Controller and then to ResponseEntity. I need to know the Best Practise (Coding Standards) for such things. Please assist.

Good Talk on Testing :-). However, there are other scenarios that weren't covered in this. Especially the scenario where you have an application that uses a third party OAuth2 authentication. We saw the use of `MockMvc` which is fine when you want to access a resource like `/home`. However, with a web application that uses OAuth2, the test won't be able to access that resource as easily. And this would have been good to see.

[@KAUSHIKAKALI]

Here is a good article for testing with OAuth2 www.kaushikbaruah.com/posts/mock-authorization-server-spring-boot-integration-test/

@@KAUSHIKAKALI I read the article, and followed the steps to the letter, but keep getting errors like ... org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'authorizationTestServer
