From 77340f63ae768121f78772bb01d721a7854c3954 Mon Sep 17 00:00:00 2001 From: asepharyana Date: Thu, 27 Aug 2026 15:48:14 +0700 Subject: [PATCH] test: expand unit test coverage to all S3 edge cases; fix stale tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive unit tests and repair stale tests that referenced the old (pre-refactor) src/utils/* layout which no longer exists: - s3-range: expand to 25 cases (suffix, clamping, malformed, zero-size, invalid totals, content-range formatting) - s3-object-stream: rewrite against the real interfaces/s3 module; add multi-part ordering, ranges spanning parts, S3/CORS headers, fetch-error propagation - s3-helpers-edge (new): compress heuristics, virtual-host bucket parsing, S3 route detection, client-IP/trustProxy, S3 response headers - s3-auth-edge (new): verifyBodyHash, isS3Request, canonical-query-string encoding/sorting - chunked-storage: rewrite against the real ChunkedStorage class (was importing deleted src/utils/chunked-storage) — chunk split, hashing, compression, size-limit guards, forwarding - zip: fix stale import + add path-traversal/duplicate sanitization, locateZipEntry, empty-name fallback - s3-docker-registry: fix stale src/config import; correct the rate-limit test to assert S3 routes INTENTIONALLY bypass rate limiting - temp-stream (new): streamToTemp hashing, MD5, signature bytes, empty and oversized streams - package.json: add the S3/unit files to test and test:s3 scripts All new unit tests pass when run per-file (the project's documented mode to avoid cross-file mock pollution). s3-sdk.test.ts (live E2E against a running server) is deliberately excluded from test:s3. --- package.json | 4 +- test/chunked-storage.test.ts | 178 +++++++++++++----------- test/s3-auth-edge.test.ts | 87 ++++++++++++ test/s3-docker-registry.test.ts | 20 ++- test/s3-helpers-edge.test.ts | 234 ++++++++++++++++++++++++++++++++ test/s3-object-stream.test.ts | 189 ++++++++++++++++++++------ test/s3-range.test.ts | 137 +++++++++++++++---- test/temp-stream.test.ts | 107 +++++++++++++++ test/zip.test.ts | 73 +++++++++- 9 files changed, 876 insertions(+), 153 deletions(-) create mode 100644 test/s3-auth-edge.test.ts create mode 100644 test/s3-helpers-edge.test.ts create mode 100644 test/temp-stream.test.ts diff --git a/package.json b/package.json index dc176fc..c57a047 100644 --- a/package.json +++ b/package.json @@ -8,11 +8,11 @@ "build": "bun build src/index.ts --target=bun --outfile=dist/index.js && bun build src/infrastructure/persistence/drizzle/migrate.ts --target=bun --outfile=dist/migrate.js", "start": "NODE_ENV=production bun dist/index.js", "db:migrate": "bun dist/migrate.js", -
