Mockserver Usage

[dhina26]

While exploring mock server for our automated test infrastructure, we hit into below error while executing code given below

Error: APPLICATION_JSON cannot be resolved or is not a field

MvcResult response = mockMvc.perform(get("/UserCredential/rest/users") .accept(MediaType.APPLICATION_JSON)) .andExpect(status().isOk()) .andExpect(content().contentType("application/json; charset=utf-8")) .andReturn();

Passing 'MediaType.ALL' for .accept instead of 'MediaType.APPLICATION_JSON' allowed compilation to go through without any errors whereas during runtime i am hitting into below error

Exception in thread "main" java.lang.IllegalArgumentException: WebApplicationContext is required at org.springframework.util.Assert.notNull(Assert.java:112) at org.springframework.test.web.servlet.setup.DefaultMockMvcBuilder.(DefaultMockMvcBuilder.java:66) at org.springframework.test.web.servlet.setup.MockMvcBuilders.webAppContextSetup(MockMvcBuilders.java:46) at checkMockServerMain.main(checkMockServerMain.java:81)

Any help on this regard is very much appreciated

It looks like the issue you are having is related to you use of the Spring Framework with the following code: mockMvc = webAppContextSetup(webApplicationContext).build();

This is not related to MockServer, as a guess this looks to be an issue with the parameter webApplicationContext not being initialised.

I am going to close this issue as it is not related to MockServer.

Following below steps resolved WebApplicationContext issue

• create test-servlet-context.xml
• Add below annotations to the class @RunWith(SpringJUnit4ClassRunner.class) @WebAppConfiguration @ContextConfiguration("classpath:test-servlet-context.xml")
• have WebApplicationContext 'Autowired'
• content of xml file
