How to run tests using a custom WebApplicationInitializer?

Question

class MyWebAppInitializer extends WebApplicationInitializer {
  def onStartup(servletContext: ServletContext): Unit = {
      ...
  }
}

@RunWith(classOf[SpringJUnit

In your context configuration I don't see that you have a context loader listed. The AnnotationConfigWebContextLoader will locate instances of WebApplicationInitializer on your classpath, by adding this and removing the intializers (which, as you have noted, are for ApplicationContextInitializers and not WebApplicationInitializers) then you should be all set.

@RunWith(classOf[SpringJUnit4ClassRunner])
@WebAppConfiguration
@ContextConfiguration(classes = {ConfigClass.class, AnotherConfigClass.class}, loader=AnnotationConfigWebContextLoader.class))
class MyTest {
...

Here is a working example

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes={WebConfiguration.class, SecurityConfig.class}, loader=AnnotationConfigWebContextLoader.class)
@ActiveProfiles("dev")
public class AppTests {
    private MockMvc mockMvc;

    @Autowired
    protected WebApplicationContext webApplicationContext;

    @Before
    public void setup() {
        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void simple() throws Exception {
        mockMvc.perform(MockMvcRequestBuilders.get("/"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.view().name("index"));
    }
}
