Set up

• Make sure you can publish an extension. Ref - http://code.visualstudio.com/docs/tools/vscecli
• Use the sample test extensions
• This repo has 3 extension packs (1, 2, 3) which are already published
• Each has some dependencies - Look at it's package.json for dependencies
• Use these extensions for testing following scenarios (You can also come up with your own if you want to :) )
• Also do play around with changing dependencies and bumping the versions to test different scenarios for installing and updating.

Note: Publishing the extension takes a while to get reflected in the market place.

Extensions with dependencies

• Search for one of the above extensions and install
• A prompt appears asking for confirmation to install its dependencies also
• If the dependencies are already installed, then no prompt is shown
• Yes action - Installs the extension and all its dependencies and sub dependencies (transitive closure).
• No action - Install the extension alone.
• Cancel action - Cancels the installation.

Installing with dependencies

• It's status shows installing and is finished only after itself and all dependencies are installed
• If any of the dependencies is visible in the Extensions view, then it's status also shows installing and is finished only after all are installed
• If the installation fails in between, installed extensions are rolled back / uninstalled.

Updating an extension with dependencies

• If it was installed with dependencies, then update should also install any newly added dependencies
• Otherwise, update should only update itself
• Make sure the install with dependencies prompt is not shown during update
• Update All and Auto update should have the same behavior

Others

• Uninstalling an extension (with dependencies) is atomic - uninstalls only itself.
• Behavior of Install / update / uninstall an extension with out dependencies is not changed
