This task is to investigate the problem why it is not possible to get extensions when trying to run tests of a vscode extension on top of che-theia, in other wordsvscode.extensions.getExtension(id) returns Cannot read property 'getExtension' of undefined.

It is needed for #18219.

Che version

Steps to reproduce

1. Create a workspace from

apiVersion: 1.0.0
metadata:
  name: che-helloworld-test-sample
components:
  - mountSources: true
    memoryLimit: 3Gi
    type: dockerimage
    image: 'quay.io/eclipse/che-theia-dev:next'
    alias: che-dev
  - type: chePlugin
    reference: 'https://raw.githubusercontent.com/svor/che-vscode-extension-tests/main/meta.yaml'
  - id: timonwong/shellcheck/latest
    type: chePlugin
  - id: eclipse/che-theia/next
    memoryLimit: 1024Mi
    type: cheEditor

2. Open theia-ide terminal and clone https://github.com/timonwong/vscode-shellcheck.git into /tmp
3. Go to /tmp/vscode/shellcheck and compile the extension (yarn install, yarn compile)
4. Copy /tmp/vscode/shellcheck into /projects (cp -r /tmp/vscode/shellcheck /projects)
5. Try to run tests from the extension by executing Run VS Code extension tests command (F1 -> Run VS Code extension tests)

Another way with vscode extension:

1. Create a workspace from

apiVersion: 1.0.0
metadata:
  name: extension-test-sample
projects:
  - name: extension-tests-runner
    source:
      location: 'https://github.com/svor/extension-tests-runner.git'
      type: git
components:
  - mountSources: true
    memoryLimit: 3Gi
    type: dockerimage
    image: 'quay.io/eclipse/che-theia-dev:next'
    alias: che-dev
  - type: chePlugin
    reference: 'https://raw.githubusercontent.com/svor/extension-tests-runner/main/meta.yaml'
  - id: ms-vscode/node-debug2/latest
    type: chePlugin

2. Open theia-ide terminal and go to /projects/extension-tests-runner
3. Run yarn and yarn compile
4. Run tests from /projects/extension-tests-runner by executing a command: F1 -> Run VSCode Extension's Tests From /projects

Additional context

[benoitf]

if it's from inside a .theia plug-in I think it's plugins.getPlugin(id) no ?

[svor]

@benoitf It's inside .theia plug-in that collects and runs tests from VSCode extension which contain vscode.extensions.getExtension(id), like https://github.com/timonwong/vscode-shellcheck/blob/master/test/suite/extension.test.ts#L22.

Maybe it should be another VSCode extension to collect and run tests not Theia plugin.

[svor]

I tried to run tests from VSCode extension and from Theia plugin and in both cases it is not possible to read extensions
