  },
)

// Fetch user data
await fetchUser('1')

// Inject mock
const getUserMock = async (userId: string) => ({ id: userId })
await fetchUser.inject({ getUser: getUserMock }).exec('1')

// with redux-thunk
export const fetchUserAction = inject({ getUser })(

    const user = await injects.getUser(userId)
