This version is still in development and is not considered stable yet. For the latest stable version, please use Spring Framework 6.0.25!

Setup Features

No matter which MockMvc builder you use, all MockMvcBuilder implementations provide some common and very useful features. For example, you can declare an Accept header for all requests and expect a status of 200 as well as a Content-Type header in all responses, as follows:

  • Java

  • Kotlin

// static import of MockMvcBuilders.standaloneSetup

MockMvc mockMvc = standaloneSetup(new MusicController())
	.defaultRequest(get("/").accept(MediaType.APPLICATION_JSON))
	.alwaysExpect(status().isOk())
	.alwaysExpect(content().contentType("application/json;charset=UTF-8"))
	.build();
// Not possible in Kotlin until https://youtrack.jetbrains.com/issue/KT-22208 is fixed

In addition, third-party frameworks (and applications) can pre-package setup instructions, such as those in a MockMvcConfigurer. The Spring Framework has one such built-in implementation that helps to save and re-use the HTTP session across requests. You can use it as follows:

  • Java

  • Kotlin

// static import of SharedHttpSessionConfigurer.sharedHttpSession

MockMvc mockMvc = MockMvcBuilders.standaloneSetup(new TestController())
		.apply(sharedHttpSession())
		.build();

// Use mockMvc to perform requests...
// Not possible in Kotlin until https://youtrack.jetbrains.com/issue/KT-22208 is fixed

See the javadoc for ConfigurableMockMvcBuilder for a list of all MockMvc builder features or use the IDE to explore the available options.
