Do you have experience using tools for intercepting and analyzing network traffic?

Yes, experience using tools for intercepting and analyzing network traffic is often necessary in QA and automation for debugging and verifying interactions between the client and server.

Popular tools:

• Wireshark — a powerful sniffer for capturing and analyzing packets at the network level.
• Fiddler — a proxy server for intercepting HTTP/HTTPS traffic, useful for web applications.
• Charles Proxy — similar to Fiddler, often used for mobile applications.
• Postman — although it is an API testing tool, it allows viewing and modifying requests.

Example: using Fiddler, you can intercept application requests to the server, check the correctness of headers, request body, and response, which helps identify errors in the API or application logic.
