Configuring MockMvc

MockMvc can be setup in one of two ways. One is to point directly to the controllers you want to test and programmatically configure Spring MVC infrastructure. The second is to point to Spring configuration with Spring MVC and controller infrastructure in it.

For a comparison of those two modes, check Setup Options.

To set up MockMvc for testing a specific controller, use the following:

Java
Kotlin

class MyWebTests {

	MockMvc mockMvc;

	@BeforeEach
	void setup() {
		this.mockMvc = MockMvcBuilders.standaloneSetup(new AccountController()).build();
	}

	// ...

}

class MyWebTests {

	lateinit var mockMvc : MockMvc

	@BeforeEach
	fun setup() {
		mockMvc = MockMvcBuilders.standaloneSetup(AccountController()).build()
	}

	// ...

}

Or you can also use this setup when testing through the WebTestClient which delegates to the same builder as shown above.

To set up MockMvc through Spring configuration, use the following:

Java
Kotlin

@SpringJUnitWebConfig(locations = "my-servlet-context.xml")
class MyWebTests {

	MockMvc mockMvc;

	@BeforeEach
	void setup(WebApplicationContext wac) {
		this.mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
	}

	// ...

}

@SpringJUnitWebConfig(locations = ["my-servlet-context.xml"])
class MyWebTests {

	lateinit var mockMvc: MockMvc

	@BeforeEach
	fun setup(wac: WebApplicationContext) {
		mockMvc = MockMvcBuilders.webAppContextSetup(wac).build()
	}

	// ...

}

Or you can also use this setup when testing through the WebTestClient which delegates to the same builder as shown above.
