test: improved test robustness
This Pull Request addresses an issue regarding the testing of the handling and generation of Access-Control-Allow-Headers header. Through the application of mutation testing, I have identified a potential mutation in the configuration logic that was not covered by the existing tests (issue fully explain in this threat).
Proposed Change
To mitigate this, I suggest changing the assertion method from assert.equal to assert.strictEqual in the test/test.js file, specifically at line 444. This alteration would ensure that the tests verify not only the value but also the exact type of the header content, thereby preventing potential type coercion issues.
Additional Information
This Pull Request has been created following the directions of @UlisesGascon.
Looking forward to your feedback and approval.
Thank you for considering this enhancement.
Best regards.
