Don’t use any classes of the service project in your integration test project.Don’t have a dependency to the service project.As long as the REST API doesn’t change your tests will work. They don’t break in case of internal changes within the service. Therefore, you should never rely on the internals of the RESTful service under test. Tests for RESTful services are black box tests. Decoupling and Dependencies Never Rely on Internals of the REST Service And finally, I personally don’t like Spring’s usage of many statically imported methods. Besides, you can test network failures (timeouts, throttling, unreachable server) more easy and reliable. So during the tests, your client behaves differently than in production. The MockRestServiceServer intercepts into the RestTemplate code. However, I still prefer OkHttp’s MockWebServer because it spins up a real server on a dedicated port. If your client uses Spring’s RestTemplate, check out the MockRestServiceServer. You can also use the MockWebServer in an integration test in the test project. You can use AssertJ to check the returned (and deserialized) POJO in the response public void createBlogAndCheckExistence () I like it much more than Hamcrest, because AssertJ guides you to find the fitting matcher for the current type. Use AssertJ to Check the Returned POJOsĪssertJ is an awesome library to write fluent, readable and typesafe test assertions. Otherwise, Jackson will complain about the missing default constructor. Please note, that you have to add the jackson-module-kotlin to your classpath in order to let the deserialization fly. The Java Ecosystem deserves this Language”. If you want to learn more about Kotlin check out my post “Kotlin. This way, we don’t need fluent setters at all.

They make the constructor invocation very readable. Moreover, Kotlin supports named arguments. The defined data class BlogDTO already contains a constructor, hashCode(), equals(), toString() and copy(). With Kotlin we can significantly reduce the boilerplate. Val newBlog = BlogDTO ( name = "Example", description = "Example", url = ") Rest-Assured provides a nice fluent API to create readable tests for REST resources.ĭata class BlogDTO ( val name : String, val description : String, val url : String ) //usage: The service provides the following resources that we want to test: /blogs Let’s code! Assume, we want to test a RESTful service offering information about blogs. For this, use sub-methods with a nice descriptive name. Write tests that can be read like a story.

Its working with give observer to subscribe method. I think you forgot to set albumDao.getAlbums("").subscribe(TEST_OBSERVER_HERE)
