Test Telemetry Command's extension suppot

[lramos15]

Test for #76029

• Mac @rebornix
• Linux @mjbvz
• Windows @alexr00

Complexity: 2

1. Install an extension
2. Create a file in the extensions installed directory called telemetry.json copy and paste this into it:

{
  "events": {
    "E1" : {
        "E1P1" : { "classification": "SystemMetaData", "purpose": "FeatureInsight" }
      }
  }
}

3. Run --telemetry. Ensure that the event shows up under the appropriate extension in the JSON output.

@lramos15 are there any other steps? I'm testing on Windows and I just get this:

D:\repos\Microsoft\vscode>code-insiders --telemetry
Unable to read VS Code telemetry events!

D:\repos\Microsoft\vscode>code-insiders . --telemetry
Unable to read VS Code telemetry events!

There's not any other steps and that is just error message given when VS code fails to read either the shipped JSON or the one in the extension folder. I'll investigate this and see what's going on.

@alexr00 The JSON previously provided in the test comment was not valid JSON syntax and therefore was failing when the function tried to parse it. I have updated the example snippet. Please try to run it again with the newly provided snippet and it should work. Sorry about that.

@lramos15 I can still see the same error Unable to read VS Code telemetry events with latest telemetry content on macOS

{
  "events": {
    "E1" : {
        "E1P1" : { "classification": "SystemMetaData", "purpose": "FeatureInsight" }
      }
  }
}

The reason that it failed on my machine is I have a symlink in the extension folder which now points to a folder no longer exits. As the file doesn't exist,

vscode/src/vs/platform/environment/node/argv.ts

Line 225 in a122c88

const dirs = readdirSync(extensionsPath).filter(files => statSync(join(extensionsPath, files)).isDirectory());
