QA Instructions

QA Testing Instructions for PR: Bump typescript-eslint from 8.56.0 to 8.57.2

---

Summary

This PR updates the typescript-eslint package (and its related sub-packages) from version 8.56.0 to 8.57.2. This includes some bug fixes and minor enhancements. The primary code changes are updates to the version and hash values in package-lock.json.

Test Environment Setup

1. Ensure node and npm are installed and configured for the project.
2. Run npm install to install the updated dependencies.

---

Test Scenarios

1. Verify Installation and Build

   • Steps:
     1. Run npm install to ensure all dependencies install correctly.
     2. Run the project's build command (e.g., npm run build) and verify it completes without errors.
   • Expected Result:
     • Dependencies should install successfully.
     • The project should build without errors.

2. Run ESLint

   • Steps:
     1. Run the project's linting command (e.g., npm run lint or eslint .).
   • Expected Result:
     • No unexpected errors or new warnings should appear, assuming the project was previously passing linting.

3. Run Tests

   • Steps:
     1. Run the project's test suite using its designated command (e.g., npm test or npx vitest).
   • Expected Result:
     • All tests should pass successfully, with no unexpected test failures.

4. Verify Critical ESLint Rule Behavior

   • Steps:
     1. Test the following eslint rules updated in this release:
        • prefer-optional-chain: Ensure that unused closing parentheses after an optional chain do not raise errors.
        • array-type: Ensure Array and ReadonlyArray without type arguments are ignored by this rule.
        • no-restricted-types: Ensure banned generics are flagged in extends or implements clauses.
        • no-unsafe-return: Verify no false positives for unwrapping generics.
        • no-useless-default-assignment: Verify false positives for unresolved type parameters are skipped.
        • prefer-readonly-parameter-types: Ensure proper handling of type alias information.
   • Expected Result:
     • The mentioned rules should function as described in the release notes, with appropriate results for provided example code snippets (refer to release notes for cases: typescript-eslint 8.57.2).

---

Regression Risks

1. Code Compatibility with Updated Rules:
   • The ESLint rules may now enforce stricter checks or have fewer false positives. Verify that no unexpected lint errors occur in the existing project codebase.
2. Test Coverage:
   • Ensure test cases that rely on TypeScript type-checking (e.g., that may use no-unsafe-return) behave as expected with the updated version of typescript-eslint.

---

Things to Watch For

• Ensure no breaking changes in eslint or typescript-eslint behavior for already configured rules.
• If there are project-specific custom ESLint rules built on typescript-eslint, ensure their behavior remains consistent with expectations after the update.

---

If you discover any issues during testing, document the exact error messages or unexpected behavior in the PR discussion for further investigation.
