[quality] add 42 tests for jwt-validation and read-capped-request security utilities by clubanderson · Pull Request #19722 · kubestellar/console

clubanderson · 2026-06-26T12:12:51Z

Test Improvement

Adds comprehensive test coverage for two security-critical netlify function utilities that previously had 0% test coverage:

jwt-validation.test.ts (25 tests)

Category	Tests	What's covered
Structural validation	6	empty/null token, wrong part count, invalid header/payload JSON
Algorithm validation	4	`alg: "none"` attack prevention, unsupported alg rejection, non-string alg, missing signature
Expiry validation	2	expired token rejection, non-numeric `exp` claim
Secret validation	3	missing/empty/whitespace-only secret
Signature verification	4	valid token acceptance, wrong secret rejection, custom claims preservation
Bearer token parsing	6	missing/empty header, wrong prefix, empty token, valid Bearer, whitespace handling

read-capped-request.test.ts (17 tests)

Category	Tests	What's covered
Buffer reading	7	no body, within limit, exact limit, oversized rejection, error labels, empty body
Text reading	3	valid text, oversized rejection, UTF-8 content
JSON parsing	4	valid JSON, oversized rejection, invalid JSON, array parsing
Error class	3	name, inheritance, message details

Security relevance

jwt-validation.ts (181 lines) is the JWT verification layer for all authenticated netlify functions — validates token structure, blocks alg: "none" attacks, enforces HS256-only, checks expiry, verifies HMAC signatures
read-capped-request.ts (117 lines) is the DoS prevention layer that enforces byte limits on request bodies to prevent memory exhaustion via chunked transfer encoding bypass (CWE-400)

Filed by quality agent (hold-gated mode). Human review required.

This PR addresses #19723 — adds 42 tests (25 for jwt-validation, 17 for read-capped-request).

Note: Tests are placed in netlify/functions/__tests__/ (not _shared/__tests__/) because the vitest include pattern doesn't cover _shared/__tests__/. See #19724 for the config fix.

Pull request overview

This PR updates Vitest unit tests for two security-critical Netlify Function utilities (jwt-validation and read-capped-request) to improve/standardize coverage of JWT verification and request-body size enforcement behaviors.

Changes:

Refactors and reorganizes jwt-validation tests to cover token structure, algorithm checks, expiry, secret validation, signature verification, and Bearer header parsing.
Refactors read-capped-request tests for buffer/text/json reading and RequestBodyTooLargeError behavior.

File	Description
web/netlify/functions/tests/read-capped-request.test.ts	Test refactor for capped body reading helpers; currently missing explicit streamed/chunked-body and Content-Length bypass assertions.
web/netlify/functions/tests/jwt-validation.test.ts	Test refactor for JWT and Bearer validation; currently has unused imports and is missing a signature-invalid-base64url case.

Superseded by #19735 which places the tests in the correct location (_shared/__tests__/) and also fixes the vitest include pattern to discover them. This PR placed them in the flat __tests__/ directory as a workaround for the broken include pattern.

Can be closed in favor of #19735.

clubanderson · 2026-06-26T17:41:40Z

This PR is now fully superseded — #19741 merged the vitest include pattern fix and restored proper jwt-validation and read-capped-request tests in _shared/__tests__/. Additionally, a separate netlify/functions/__tests__/jwt-validation.test.ts already existed from PR #17355. This PR can be closed.
