    ...jest.requireactual("react-redux"),
    useselector: jest.fn(),
}));

describe("blabla", () => {
    const mockedstate = {
        user: {
            firstname: "john",
        },
    };

    beforeeach(() => {
        redux.useselector.mockimplementation((callback) => {
            return callback(mockedstate);
        });
    });
});
