![]() Next, we add a class that extends the previous abstract class to make use of MockWebServer. ![]() Finally, the last configuration step would be to shut down the MockWebServer when finish our test. Next, we need to start the MockWebServer before any test is executed, similar to by specifying the port where we want to run it. Let’s add MockWebServer to our tests using Spock: = class ResourceISpec extends Specification MockMvc mockMvcĪs we can see in this code snippet, we have added the MockWebServer class, which has been imported as static. To use the libraries, we have added both the mockwebserver and okhttp dependencies. Let’s add the following dependencies to include the necessary libraries: Using MockWebServer MockWebServer Dependencies Overall, MockWebServer provides a convenient and powerful tool for testing the HTTP interactions of your Spring applications, allowing you to create reliable and deterministic tests in a controlled environment. We can use MockWebServer alongside other testing frameworks like JUnit or Spock to create comprehensive and reliable tests for your Spring applications involving HTTP interactions. Easy Integration with Spring Testing: You can easily integrate MockWebServer into your Spring tests, whether you use the Spring MVC Test framework or WebClient.This flexibility enables you to simulate different scenarios and edge cases, such as testing error handling or specific response formats, without relying on the actual external services. Flexible Response Configuration: MockWebServer allows you to configure various aspects of the responses, including response codes, headers, and response bodies.You have control over the responses returned by the MockWebServer, making your tests deterministic and consistent. This ensures that your tests are not affected by the availability or reliability of those external services. Isolation and Deterministic Testing: By using MockWebServer, you can isolate your Spring application from the actual web services it communicates with during testing.MockWebServer mocks web server behavior, intercepts HTTP requests, and provides predefined responses for testing different scenarios and HTTP interactions. Testing HTTP Interactions: Spring applications often rely on making HTTP requests to external APIs or services.MockWebServer acts as a web server, intercepting the made request and returning a pre-established response body. The use of MockWebServer allows us to mock any request made through our WebClient. In this article, we are going to delve into how to perform integrated tests using MockWebServer with WebClient of Spring.
