From 0224bd9acfdbd453b03954688fb62edbab6719d3 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 10 Apr 2026 01:09:26 +0000 Subject: [PATCH] Add comprehensive test coverage, fuzz testing, and cargo-audit CI LSP (16 new tests): - Tests for new(), connect_verisimdb(), fetch_schema(), handle_hover(), handle_goto_definition(), handle_completion() including schema-based completions and error cases DAP (24 new tests): - Refactored testable code from main.rs into lib.rs (DapRequest, DapResponse, execute_vql_query, dispatch_request) - Tests for all DAP commands (initialize, launch, setBreakpoints, threads, stackTrace, scopes, variables, continue, disconnect) - Tests for VCL query execution simulation and serialization round-trips E2E security tests (8 new tests): - SQL injection, stacked queries, comment injection, UNION injection - Null byte injection, oversized input handling - Concurrent format/lint consistency across 8 threads Fuzz testing (13 new tests replacing placeholder): - Removed fake tests/fuzz/placeholder.txt scorecard stub - Added fuzz_test.rs with proptest-based fuzzing (1000+ cases each) - Raw bytes, injection payloads, Unicode edge cases, stress inputs - Verifies idempotence and determinism on adversarial input CI: - Added cargo-audit workflow for dependency vulnerability scanning Total new tests: 61 (16 LSP + 24 DAP + 8 E2E + 13 fuzz) https://claude.ai/code/session_01FxxUVqL8xdA34j7n3Ep52S --- .github/workflows/cargo-audit.yml | 44 ++++ src/interface/dap/src/lib.rs | 392 +++++++++++++++++++++++++++++- src/interface/dap/src/main.rs | 180 +------------- src/interface/lsp/src/lib.rs | 294 +++++++++++++++++++++- tests/e2e_test.rs | 179 ++++++++++++-- tests/fuzz/placeholder.txt | 1 - tests/fuzz_test.rs | 205 ++++++++++++++++ 7 files changed, 1087 insertions(+), 208 deletions(-) create mode 100644 .github/workflows/cargo-audit.yml delete mode 100644 tests/fuzz/placeholder.txt create mode 100644 tests/fuzz_test.rs diff --git a/.github/workflows/cargo-audit.yml b/.github/workflows/cargo-audit.yml new file mode 100644 index 0000000..bf6fd47 --- /dev/null +++ b/.github/workflows/cargo-audit.yml @@ -0,0 +1,44 @@ +# SPDX-License-Identifier: PMPL-1.0-or-later +# Copyright (c) 2026 Jonathan D.A.
