QA:Testcase gnome-shell activities

Description

This tests the Overview mode in GNOME.

How to test

1. In GNOME, open at least two applications (e.g. Files and a Text Editor).
2. Activate the Overview mode. You can do this by pressing the Super key (Windows key), clicking the Activities button in the top bar, or hitting the very top left corner of the screen with a mouse cursor. Verify that all those methods open and close the Overview.
3. Verify that you can switch between different applications by activating the Overview and then clicking on a particular app window thumbnail.
4. Verify that you can switch between different applications by activating the Overview and then clicking on app icons in the Dash (the bottom panel). All your currently running applications must be shown in the Dash.
5. Verify that currently running apps are visually distinguished (e.g. having a white dot) in the Dash from non-running apps. Open and close apps to confirm this feature works correctly.
6. Verify that you can close individual app windows from the Overview by clicking the close button overlay on their thumbnails.
7. Open several windows of the same application by right clicking an already running app icon in the Dash and choosing New Window (not all applications need to support this, but e.g. Files do).
8. Right click the app icon in Dash of the same application and choose Quit. All windows of that application must be closed.
9. Display the App drawer using the 9-dot icon in the Dash, and test that you can scroll in it (if applicable), open and close app folders (if present), and run new applications by clicking on them and/or drag&dropping them onto a workspace preview.
10. Verify that you can add apps from the App drawer to the Dash permanently by right clicking them and choosing Pin to Dash and/or drag&dropping them to the Dash. After closing such app, it must stay present in the Dash (just marked as non running).
11. Verify that you can unpin apps from Dash by right clicking and choosing Unpin, or drag&dropping them back to the App drawer. Such app icons must no longer be visible in the Dash after the app is closed.
12. Verify that you can modify the app order in the App drawer by drag&dropping.
13. Verify that you can create new app folders in the App drawer by drag&dropping apps onto each other and then giving the folder a name.
14. Verify that you can remove an app folder by moving all apps out of the folder.
15. Perform some additional Exploratory testing.

Expected Results

1. Overview should be rendered correctly, without graphical errors.
2. All operations should behave as expected.
3. Please report all failures to the GNOME tracker.
