API Testing and Handling Status Code Errors

Error:

When testing APIs using RequestSpecification, users may encounter errors with status codes 404 or 502. A 404 error indicates that the server could not find the requested resource, while a 502 error indicates that the server received an invalid response from an upstream server.

What causes the error?

The 404 error occurs when the requested resource is not found on the server. This could happen if the endpoint is incorrect or if the resource has been moved or deleted. The 502 error occurs when the server receives an invalid response from an upstream server, indicating that the upstream server is not reachable or is experiencing issues.

Debugging Methods:

To resolve these errors, users can try the following methods:

Method 1: Check the endpoint

Verify that the endpoint is correct and matches the URL of the resource being requested. Make sure there are no typos or missing characters in the URL.

Method 2: Verify the Request Payload

Check the payload in the request to ensure that it is in the correct format and contains all required parameters. If the payload is incorrect, the server may not be able to process the request and could return a 404 or 502 error.

Method 3: Check Network Connection

Make sure the network connection is stable and that there are no issues with the network infrastructure. A poor network connection or network outage can cause issues with API requests and may result in a 502 error.

Method 4: Check Upstream Server

If the 502 error persists, it could be due to issues with the upstream server. Check the logs of the upstream server for any issues or error messages. If the upstream server is not accessible, contact the system administrator for assistance.

Extra Information:

When encountering a 404 error, check if the resource has been moved or deleted

A 502 error can be caused by network issues, such as poor connectivity or network outages

An invalid payload can cause a 404 or 502 error in the API response

By using the above debugging methods, users should be able to resolve the 404 and 502 status code errors encountered while writing API testing code using RequestSpecification.
