mocking enum in junit issue

[Former Member]

Hello,

I am facing an issue in junit testing when i try to set an enum value to model. I am trying to write unit test for a custom populator. Its throwing nosuchmethodfound exception when i try to set enum to the source. What could be the issue ? I tried various approaches. No luck. Any inputs will be useful.

Cheers, Shen

Try as below, you have to mock enum first and then return values. final ProductAvailabilityStatus availabilityStatus = Mockito.mock(ProductAvailabilityStatus.class); Mockito.when(product.getAvailabilityStatus()).thenReturn(availabilityStatus); Mockito.when(product.getAvailabilityStatus().getCode()).thenReturn(ProductAvailabilityStatus.AVAILABLE.getCode());

Hello,

Thanks for your answer. I tried the same. But its still showing the same error.

It is an old answer. But it is incomplete, updating it in case someone bumped into here. Directly calling mock() on enum like ProductAvailabilityStatus availabilityStatus = Mockito.mock(ProductAvailabilityStatus.class) will throw error anyways. Mockito 2 supports mocking of enum, but it is experimental feature. It needs to be enabled explicitly. If someone is interested about the steps, plz check the details here https://www.w3spot.com/2022/05/how-to-mock-java-enum-or-final-class-without-powermock.html.
