Like pseudocode: mockWebServer.expectPath ('/products'). I want to configure the mock so that responses are returned conditional by path. Using MockWebServer is recommended by the Spring Team for writing integration tests.

Interacting with MockWebServer from our test cases allows our code to use real HTTP calls to a local endpoint.We get the benefit of testing the intended HTTP interactions and none of the challenges of mocking a complex fluent client. Here is the test code testing a 200 Success response: baseUrl (server.url ('/')) // Other builder methods.build () Second, to get responses from the mock web server, you need to enqueue the expected. Retrofit retrofit new Retrofit.Builder (). Generally, you configure your retrofit to call the server's endpoint. We are also choosing to disable the security in this test because we are testing responses and error handling, not security. If you want to set the url, you'll need to pass it to the start () method. We do that by mocking the WebClient bean we have previously created. Writing the Testīecause MockWebServer just provides a url that you can hit, we have to figure out a way to insert that url into our application context at runtime. If you want to skip to the GitHub repo with the adle file and example code, go here. It is a simple pass-through API that hits a backend and returns the response from it. Our project will include Spring Security with Client Credentials, Actuator, Spring Web, JUnit 5 and Webflux, and some other common dependencies. We will be using Spring Boot version 2.4.2 with Gradle and Java 8. Of course, you need a project to import these into. Shown below as Gradle imports: testImplementation '3:okhttp:4.0.1' testImplementation '3:mockwebserver:4.0.1' To use MockWebServer, you need two dependencies. This will allow us to test things like what our system returns when getting a 500 error from their dependencies and other complex scenarios. Better still, it enables you to test the token caching functionality that comes built into WebClient, but we won’t get to that today.

This lets you test your WebClient setup as well. In enqueueMockResponse function, we read the ImageResponse.json file and enqueue it as MockResponse. We also need to enqueue the expected responses as MockResponse. We can see that Retrofit and ImageApiService are used to create a Fake API service. We will spin up the application with the Spring context, hit the endpoint with a Spring MockMvc client, have it pass through the application, and then mock the server our service calls on the other end to return back the desired HttpStatus and response body. Spring Boot 2.2.6 introduced the DynamicPropertySource which allows you to insert the MockWebServer url into the properties at runtime. So we will set up the MockWebServer and in Before and shut down in the After. There is a way to almost replicate that functionality using MockWebServer (okhttp). Mocking a server with RestTemplate was done with Spring’s MockRestServiceServer, which was able to mock the endpoint your service would normally call. OverviewĪs many of you know, Spring is deprecating RestTemplate and replacing it with WebClient. Provides a way to set up expected requests that will be performed through the RestTemplate as well as mock responses to send back thus removing the need for an actual. Used for tests that involve direct or indirect use of the RestTemplate.

Main entry point for client-side REST testing. For a cleaner implementation of this, check out my updated blog. public final class MockRestServiceServer extends Object.
