[Bug]: Node 23 normalizes paths in a way that results in Jest finding no tests

[steveluscher]

Version

main branch

Steps to reproduce

yarn jest-jasmine-ci e2e/__tests__/jestChangedFiles.test.ts

Expected behavior

Tests pass.

Actual behavior

includePaths ends up having '../jest-changed-files-test-dir' under Node 23 instead of '.' under Node <=22. This causes git to freak out because the directory is ‘outside the repository.’

/home/sol/src/jest/e2e/__tests__/jestChangedFiles.test.ts

  ● gets changed files for git

    Command failed with exit code 128: git diff --cached --name-only -- nested-dir nested-dir/second-nested-dir ../jest-changed-files-test-dir
    fatal: ../jest-changed-files-test-dir: '../jest-changed-files-test-dir' is outside repository at '/tmp/jest-changed-files-test-dir'

      207 |   ].map(filename => path.resolve(DIR, filename));
      208 |   console.log(roots);
    > 209 |   let {changedFiles: files} = await getChangedFilesForRoots(roots, {});
          |                               ^
      210 |   expect([...files].map(filePath => path.basename(filePath)).sort()).toEqual([
      211 |     'file1.txt',
      212 |     'file2.txt',

Additional context

This appears to be because of a bug in Node 23, but that's no reason not to try to strip the trailing slash in Jest, defensively. nodejs/node#55448

Looks like this has been reverted in Node. nodejs/node#55414
