this is my project code  
const classes = useStyles();

const [projectName, setProjectName] = useState("--------");

const [projectDescription, setProjectDescription] = useState("-------");

let { id } = useParams();

const [isSubmitting, setSubmitting] = useState(false);

const [loading, setLoading] = useState(true);

when trying to update the useState in testcase like this:

const setState = jest.fn();

```
const useStateSpy = jest.spyOn(React, 'useState');

useStateSpy.mockImplementationOnce( (projectName) => [projectName= "Test Project" , setState]);

useStateSpy.mockImplementationOnce((projectDescription) => [projectDescription = "Test Data" , setState]);

```

these values of projectname and project description not changing,.
