Mock a static method with mockito
java, mocking, mockito, unit-testing
Solution
As you pointed out, it is not possible to mock static methods with Mockito and since you do not wanna use Powermock or other tools, you can try something as follows in your tests.
Create test authentication object
`Authentication auth = new ... // create instance based on your needs and with required attributes or just mock it if you do not care`
Mock security context
`SecurityContext context = mock(SecurityContext.class);`
Ensure your mock returns the respective authentication
`when(context.getAuthentication()).thenReturn(auth);`
Set security context into holder
`SecurityContextHolder.setContext(securityContext);`
Now every call to `SecurityContextHolder.getContext().getAuthentication()` should return authentication object created in step 1.
Problem
I want to mock a static method in Mockito. As far as I know this is not possible, how can I get around the problem? powermock is not an option. I want that my authentication variable won't be null. ``` Authentication authentication = SecurityContextHolder.getContext().getAuthentication(); ``` I read an answer here but I don't know how to put this answer to code. Can someone give a solution?
