Summary

Fixes #16457

When --config \ was passed from a working directory that does not contain a \package.json\ or discoverable Jest config file, Jest failed with:
\
Error: Could not find a config file based on provided values:
path: "..."
cwd: "..."
\
This was a regression introduced in #16411 in \packages/jest-config/src/index.ts. While evaluating \suppliesGlobalConfig,
esolveConfigPath(root, cwd, projectIsCwd)\ was unconditionally invoked on
oot\ (\cwd) even when !skipArgvConfigOption\ was true (meaning the project config was already supplied by \�rgv.config).

This PR:

  • Short-circuits \suppliesGlobalConfig\ when !skipArgvConfigOption\ is true.
  • Safely wraps the
    esolveConfigPath\ check in a \ ry / catch\ so unexpected resolution failures during global config supply checks do not throw unhandled exceptions.
  • Updates \CHANGELOG.md.
  • Adds an e2e regression test in \e2e/tests/config.test.ts.

Test plan

  • Added automated test in \e2e/tests/config.test.ts\ verifying --config \ runs successfully when \cwd\ has no config file.
