From 778d9e4c137d64e57f8d25e716897d78630af64a Mon Sep 17 00:00:00 2001 From: jedarden Date: Fri, 29 May 2026 08:25:01 -0400 Subject: [PATCH] feat(pdftract-69iwi): implement remote source mock server test corpus Add wiremock-based integration test infrastructure for HttpRangeSource with bandwidth tracking and all 5 critical test scenarios from plan Section 1.8. ## Files added - tests/remote/fixtures/generate_linearized.rs: Linearized PDF fixture generator - tests/remote/fixtures/linearized-10.pdf: 10-page linearized PDF with hint stream - tests/remote/integration.rs: Complete test suite with 12+ test scenarios - notes/pdftract-69iwi.md: Verification note with PASS/WARN/FAIL status ## Test infrastructure - BandwidthTracker utility for bandwidth and request counting - Mock server factories: create_range_server(), create_no_range_server(), create_416_server() - Verification helpers: assert_bytes_transferred(), assert_range_request_count() ## Critical tests implemented (Plan 1.8) 1. test_range_support_page_5_of_100: Bandwidth verification (<100KB) 2. test_no_range_fallback: Full download fallback with REMOTE_NO_RANGE_SUPPORT 3. test_416_retry_without_range: 416 response handling infrastructure 4. test_linearized_hint_stream_prefetch: Linearized PDF with hint stream 5. test_connection_drop_interrupted: REMOTE_FETCH_INTERRUPTED handling 6. test_tls_handshake_failure: Self-signed cert rejection (rcgen) ## INV-8 compliance All tests verify no panic occurs on network errors, connection drops, or TLS failures. Errors return Result<> types with appropriate ErrorKind. ## Dependencies - wiremock 0.6 (mock HTTP server) - rcgen 0.13 (self-signed TLS certificate generation) - tokio 1.x (async runtime) Co-Authored-By: Claude Opus 4.7 --- crates/pdftract-cli/Cargo.toml | 8 +- notes/pdftract-3779n.md | 101 +++ notes/pdftract-5kqbl.md | 112 ++++ notes/pdftract-69iwi.md | 157 +++++ tests/remote/fixtures/generate_linearized.rs | 130 ++++ tests/remote/fixtures/linearized-10.pdf | Bin 0 -> 3335 bytes tests/remote/integration.rs | 664 +++++++++++++++++++ tests/remote/mod.rs | 7 + 8 files changed, 1172 insertions(+), 7 deletions(-) create mode 100644 notes/pdftract-3779n.md create mode 100644 notes/pdftract-5kqbl.md create mode 100644 notes/pdftract-69iwi.md create mode 100644 tests/remote/fixtures/generate_linearized.rs create mode 100644 tests/remote/fixtures/linearized-10.pdf create mode 100644 tests/remote/integration.rs create mode 100644 tests/remote/mod.rs diff --git a/crates/pdftract-cli/Cargo.toml b/crates/pdftract-cli/Cargo.toml index b7193d9..a2894a6 100644 --- a/crates/pdftract-cli/Cargo.toml +++ b/crates/pdftract-cli/Cargo.toml @@ -44,13 +44,7 @@ path = "../../tests/fixtures/generate_scientific_paper_fixtures.rs" name = "generate_book_chapter_fixtures" path = "../../tests/fixtures/generate_book_chapter_fixtures.rs" -[[bin]] -name = "generate_fixtures" -path = "../../tests/document_model/fixtures/generate_fixtures.rs" - -[[bin]] -name = "generate_expected_json" -path = "../../tests/document_model/generate_expected_json.rs" +# Removed: generate_fixtures, generate_expected_json (files do not exist) [[bench]] name = "grep_1000" diff --git a/notes/pdftract-3779n.md b/notes/pdftract-3779n.md new file mode 100644 index 0000000..8a81f7b --- /dev/null +++ b/notes/pdftract-3779n.md @@ -0,0 +1,101 @@ +# Verification: pdftract-3779n - Rust SDK docs.rs publishing config + examples directory + +## Summary + +All acceptance criteria are **PASS**.
