Motivation and Context

​

How Has This Been Tested?

• The endpoint be accessible at api/v1/jobs/:id
• The endpoint accept HTTP PATCH requests.
• The endpoint check that the user has the appropriate permissions.
• The endpoint validate all data passed in the body of the request
• Requests to the endpoint must include a valid authentication token in the Authorization header. Authorization: Bearer
• Given a request with a valid job post ID, when the user is authenticated and authorized, the system should update the user with a status code of 200
• Given a request with an invalid or non-existent user ID, when the user is authenticated and authorised, the system should return a 404 Not Found status.

• Successful response with valid id
• invalid job post id
• Missing job post id
• invalid request body
• Appropriate status code
