Running go test -cover ./... in the root directory here or running the test suite in mock_v9 directory shows the test failure result
wrong number of arguments in DoAndReturn func for *mock_v9.MockCmdable.MGet: got 3, want 2 [/build/mock_v9/redis_cache_v2_test.go:36]
This is not expected as 3 arguments are supplied and available on the method, I would expect this test which is in file redis_cache_v2_test.go to pass.
mockRedis.EXPECT().MGet(gomock.Any(), gomock.Any(), gomock.Any()).DoAndReturn(func(context context.Context, cacheKey string, deleteKey string)
To generate the mock files (which already exist).
