# Testing Files and Attachments
This test contains instructions for the core team to manually test common attachment types. All files for testing are stored in the [mm_file_testing](https://www.dropbox.com/sh/i7ft8is5hbhk8ii/AAAyM-WG-X2jiQOgg6-E3MmLa?dl=0) dropbox folder. Follow these instructions:

1. Download the entire [mm_file_testing](https://www.dropbox.com/sh/i7ft8is5hbhk8ii/AAAyM-WG-X2jiQOgg6-E3MmLa?dl=0) folder. 
2. Drag and drop each file type into Mattermost to upload it.
3. Post the file attachment

**Notes:**  
- All file types should upload and post.
- Read the expected for details on the behavior of the thumbnail and preview window.  
- The expected behavior of video and audio formats depends on the operating system, browser and plugins. View the permalinks to the Public Test Channel on Pre-Release Core to see the expected cases.   
- If the browser can play the media file, media player controls should appear. If the browser cannot play the file, it should show appear as a regular attachment without the media controls.
