Mockito Exception - when() requires an argument which has to be a method call on a mock

Question

I have a very simple test case that is using Mockito and Spring Test framework. When I do

when(pcUserService.read(\"1\")).thenReturn(pcUser);

Answer 1

You need to create a MOCK of pcUserService first, and then use that mock.

PcUserService mock = org.mockito.Mockito.mock(PcUserService.class);
when(mock.read("1")).thenReturn(pcUser);
