# Explanation
Let’s explore how the above test works:

- **Line 43-45:** We send `GET` requests to the specified URLs as `get-tags` , `get-feed`, and `get-articles` .
- **Line 47:** We authenticate the `user` and visit the `home` page.
- **Line 49-51:** We wait for the response to the `get-tags` and `get-feed`. Then we visit the `Global Feed` and wait for the response to the `get-articles`.
- **Line 53-54:** We iterate through articles to check if they are present.
