The Collapse All button is the VS Code's API. As far as I know, there is no such API to expand a node. Did you see any example in other VS Code extensions?

Oh, bummer

馃槻. Wonder if there's a feature request already for that 馃?

No but I'll keep my eyes open. Thanks @jdneo !
Thanks, if there is any update/new findings, please feel free to comment here.
Found one! Search has one 馃槉

Thank you! Let me check the implementation
Looking forward for this enhancement :eyes:
This is still limited by API, see: https://github.com/microsoft/vscode/issues/88682

Bummer. Thanks for looking into it again. Should we close the issue again?
@spottedmahn just make it open is fine. Then I can always take a look at the upstream issue when I see it.
In my opinion the reason for an 'expand all' button comes from the wish to see the status of running/completed tests quickly. A collapsed node does not have any indication if tests inside it are still running/succeeded/failed. Adding this information to classes/packages/projects would be more appropriate.
