# Link Preview Tests
Link previews should embed previews of the contents of a hyperlink from a message or comment in the center channel directly below the message or comment.
Post location variation:
1. Post message in center channel with RHS closed (Expected: preview of first link renders under message)
2. Post message in center channel with RHS open (Expected: preview of first link renders under message)
3. Post comment in RHS (Expected: link preview does not render)
4. View comment in center channel with RHS closed (Expected: preview of first link renders under message)
5. View comment in center channel with RHS open (Expected: preview of first link renders under message)
6. Search for post in RHS with link (Expected: no previews render in search results)
Test the above variations with the below sample messages (e.g. 1-A, 2-B, 3-C, 4-D, etc.)
```
#### A) No link preview
