How to mock ObjectMapper.readValue() using mockito

Question

I\'m testing a service layer and not sure how to mock ObjectMapper().readValue in that class. I\'m fairly new to mockito and could figure out how to do

Answer 1

Problem is with the this line where you are mocking the call to objectmapper.

Mockito.when((objMapper).readValue(“”,ConfigDetail.class)).thenReturn(configDetail);

Correct syntax is

Mockito.when(objMapper.readValue(“”,ConfigDetail.class)).thenReturn(configDetail);

Notice the bracket position. When using Spy or Verify, the bracket position is diff. then when using when-then syntax.
