As software testers, we need to focus on every aspect of the system to prevent bugs and defects from reaching the end user.

Today, while testing one of the project APIs, I encountered multiple entries in the network tab that confused me. I noticed there were two different icons. One clearly represented the API calls, but I wasn’t sure about the purpose of the second icon.

In this image, the selected icon represents the API that fetches data.

But what does this selected icon indicate?

I was testing the project’s APIs in the browser’s network tab and noticed several API calls, each with an icon. I recognized one as representing an API that fetches data, but the second icon was unfamiliar. I tried to understand its purpose by analyzing the network requests but couldn’t figure it out. I expected the second icon to have a clear meaning, like the API icon, and was hoping to determine if it indicated a different request type, an error, or another function.
