vscode findFiles returns nothing but npm glob returns correct results - file

Question

I'm writing and vscode extension in which I need a list of the test files inside workspace.
To find the test files I'm using the default testMatch from the jest.config.js which is:
[
'**/__tests__/**/*.[jt]s?(x)',
'**/?(*.)+(spec|test).[jt]s?(x)'
]
My problem is that vscode.workspace.findFiles returns empty array and I cannot set it up to get correct results, but using Glob package the output is correct.
protected async findTestFiles(
matchTestsGlobPatterns: string[]
): Promise<vscode.Uri[]> {
const testFilesUris: vscode.Uri[] = [];
const glob_testFilesUris: vscode.Uri[] = [];
const { name: workspaceName, workspaceFolders } = vscode.workspace;
if (workspaceName === undefined || workspaceFolders === undefined) {
throw new Error(`No active workspace${!workspaceFolders ? ' folders' : ''}.`);
}
for (let folderIdx = 0; folderIdx < workspaceFolders.length; folderIdx++) {
const folder = workspaceFolders[folderIdx];
// - by vscode.workspace.findFiles
for (let patternIdx = 0; patternIdx < matchTestsGlobPatterns.length; patternIdx++) {
const currentPattern = matchTestsGlobPatterns[patternIdx];
const pattern = new vscode.RelativePattern(
folder.uri.fsPath,
currentPattern
);
const files = await vscode.workspace.findFiles(
pattern,
'**/node_modules/**'
);
testFilesUris.push(...files);
}
console.log('by [vscode.workspace.findFiles]', testFilesUris.length);
// - by npm Glob
var glob = require('glob');
for (let patternIdx = 0; patternIdx < matchTestsGlobPatterns.length; patternIdx++) {
const currentPattern = matchTestsGlobPatterns[patternIdx];
const files: any[] = await new Promise((resolve, reject) => {
glob(
currentPattern,
{
absolute: true,
cwd: folder.uri.fsPath,
ignore: ['**/node_modules/**']
},
function (err: Error, files: any[]) {
if (err) {
return reject(err);
}
resolve(files);
}
);
});
glob_testFilesUris.push(...files);
}
console.log('by [npm Glob]', glob_testFilesUris.length);
}
// #todo: remove duplicates.
return testFilesUris;
}
The example console output of this function for some project is:
by [vscode.workspace.findFiles] 0
by [npm Glob] 45
Project structure:
rootFolder
src
__tests__
files.test.ts
...
utils
array.test.ts
...
So my question is how do I call vscode.workspace.findFiles to get correct results, or is there known problem with this function?
I have found some kind of answer to the question.
The problem is ?(x) in patterns. The vscode.workspace.findFiles does not work with this pattern as other packages do. If remove it from mentioned glob patterns they work except the .jsx | .tsx files are ommited.

Answer 1

After deep dive into vscode github's issues I have learned (here) that vscode.workspace.findFiles does not support extended patterns like ?(patterLike)
