Tests do not support multi-root workspaces

[DonJayamanne]

• Ensure Test Explorer also supports multiple folders (already supported)
• Fix rest of code (3 files).

[DonJayamanne]

• How is the test explorer meant to behave (i.e. whats the UX)?
• Suggestion:
  • Add a folder icon with tooltip Select Folder to the top of the explorer to change/pick the folder
  • Clicking this icon will display the standard VS Code dropdown list used to pick a folder from available folders in a multi-root workspace.
  • Based on the selection, we display the name of the selected folder as a root node in the tree view.
  • Default is to always display the first folder

Prescribed solution

• Add a folder icon to the toolbar
• Clicking this new icon will display standard VSC workspace picker , then refresh explorer
• By default display test explorer for first workspace
• Existing commands will need to display workspace picker prompt
  • Run All Tests, Discover Test, etc....

@ericsnowcurrently @d3r3kk
Thanks for the suggestion guys..

@qubitron Here's another approach for the test explorer and multiroot.

• No changes to single root workspace
• Extension already supports multi-root workspaces, just the test explorer doesn't
• When you use any command related to testing, you'll be prompted to select a workspace folder (existing functionality).
• Test Explorer:
  • As and when tests are discovered the test explorer will be displayed (existing functionality)
  • However, the root node in the tree view will contain the name of the workspace folder
  • Clicking on any icons on the test explorer will prompt user to select workspace folder (this happens because the icons are wired to use existing commands in command palette)
  • If you click on discover icon and select another folder and tests are discovered, then another node will be added to the test explorer containing the name of that corresponding workspace folder
  • I.e. as and when tests are discovered, the tree view will dynamically add nodes for each workspace with tests.

Suggestions

• Add hover icons for the test folder node for Run All Tests, Debug All Tests, Discover Tests.
• This is a single click, as opposed to clicking icons on toolbar, wher user will be prompted to select a workspace folder.
