I don’t understand the failing test.

  1) Specifications of supported extensions: tests
       ensures that
         each supported
           extension
             does NOT have
               same declaration with different 'extensions':
     AssertionError: expected [ Array(1) ] to be empty
      at /home/remco/Projects/vscode-icons/out/test/iconsManifest/specsExtensions.test.js:2:5377
      at Array.forEach (<anonymous>)
      at Context.<anonymous> (out/test/iconsManifest/specsExtensions.test.js:2:5042)
      at process.processImmediate (node:internal/timers:475:21)

If I add the extension to the entries that already exist, the icon isn’t applied.

@remcohaszing I think I fixed it? I have no idea why exactly what I did works, but I changed it from

    {
      icon: 'vscode',
      extensions: ['code-workspace'],
      format: FileFormat.svg,
    },

to

    {
      icon: 'vscode',
      extensions: ['code-workspace', 'code-snippets'],
      filenamesGlob: [],
      extensionsGlob: [],
      filename: false,
      format: FileFormat.svg,
    },

Tried it with only code-workspace in there, only code-snippets, and of course both - test runs without issues on my end. As I said I have no clue why that works, but if it works then it works 🤷

That works! Thanks!
