Junit Test Case with RequestParameterMap not working

Question

Hi All,

Am writing one test case with RequestParameterMap, but it's throwing nullpointer exception .

Below one is the code snippet .

@2785667
public void validateUserData() {
Map<String, RequestParameter[]> params = new HashMap<>();
params.put("firstName", getRequestParameter("firstName", "test"));
params.put("lastName", getRequestParameter("lastName", "test last"));

when(request.getParameterMap()).thenReturn(params);
RequestParameterMap requestParameterMap = Mockito.mock(RequestParameterMap.class);
when(requestParameterMap.entrySet()).thenReturn(params.entrySet());

UserInfo user = userService.getUserInfo(requestParameterMap);
assertEquals("firstName", user.getFirstName());
}

when i try to get the values from requestParameterMap , it's giving null pointer exception.

Could you please help me resolve this issue .

Thanks

Have you tried using AEM Mock's AemContext to create mock sling request context?

I highly, highly recommend using AEM Mocks when possible rather than mocking out everything yourself. These sorts of problems should go away, and also lets you write more natural tests.

can you please post complete test class here,

== The below code is correct and should work ==

RequestParameterMap requestParameterMap = mock(RequestParameterMap.class);
when(requestParameterMap.entrySet()).thenReturn(params.entrySet());

=== try this one

when(parameterMap.isEmpty()).thenReturn(Boolean.FALSE);
when(parameterMap.getValue("firstName")).thenReturn("test");
