What should go into Mime Type tests

Each activity has mime types which it is supposed to be able to support; often, this is listed on the activity's wiki page.

• We need to test that each activity is able to open the mime type files that it supports, from the Journal, Clipboard, the Activity itself, or the Browser (whichever ones it can/should)
  • It would be good to upload the files that should be used to test with, so that everyone who tests is using the same files.
• We also need to test that activities create files of a certain mime type. Paint for example should create a .png or .jpeg file.
  • Since file extensions cannot be seen in the Journal, one will need to either go into the file system to check, or move the files onto a usb stick and look at them on a normal laptop.
