Bounty: 250
I have this test in my app:
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration(classes = ApplicationTestConfig.class)
@MockBeans({ @MockBean(SwaggerConfig.class)})
public class AuthorisationControllerTest implements WebMvcConfigurer {
private MockMvc mockMvc;
@Autowired
private WebApplicationContext wac;
@Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
@Test
public void testAuthorisation() throws Exception {
this.mockMvc.perform(get("/test")).andDo(print()).andExpect(status().isOk())
.andExpect(content().string(containsString("Hello, World")));
}
}
but when I run the test I got this error:
15:04:10.417 [main] ERROR org.springframework.test.context.TestContextManager - Caught exception while allowing TestExecutionListener [org.springframework.test.context.web.ServletTestExecutionListener@7219ec67] to prepare test instance [eu.europa.ec.oib.kw.guards.controller.AuthorisationControllerTest@6fb219dd]
