Test tools for rspack
Flaky test detection for Rust. Runs cargo test N times and classifies each test as stable / flaky / broken with a reliability score in [0.0, 1.0]. Part of the dev-* verification collection.
Rust verification toolkit. Tests, benches, coverage, fuzz, security audit, dep hygiene, mutation, chaos, async, stress — one crate, opt in with feature flags.
Async runtime verification for Rust: timeouts, deadlock detection, task tracking, hung-shutdown probes. The async failure modes that synchronous tests miss. Part of the dev-* verification collection.
Benchmark and regression detection for Rust. Percentile stats, baseline storage, threshold gating, structured CI-gateable verdicts. Part of the dev-* verification collection.
Fault injection and recovery testing for Rust. Disk faults, network drops, latency injection, deterministic crash points, partial writes. Part of the dev-* verification collection.
Calibrated GitHub Actions workflow generator for Rust crates. Library API + CLI binary. Byte-deterministic YAML output. Part of the dev-* verification collection.
Code coverage with regression gates for Rust. Wraps cargo-llvm-cov: line / function / region kill rates, stored baselines, machine-readable verdicts. Part of the dev-* verification collection.
Dependency hygiene for Rust crates. Detect unused, outdated, and many-major-versions-behind dependencies. Wraps cargo-udeps + cargo-outdated. Part of the dev-* verification collection.
Deterministic test fixtures for Rust: disposable project trees, golden-file snapshots, controlled mock data, file-tree builders. Part of the dev-* verification collection.
Fuzz testing workflow for Rust. Wraps cargo-fuzz: budgeted runs, crash / timeout / OOM findings, deterministic reproducer paths, sanitizer choice, machine-readable verdicts. Part of the dev-* verification collection.
Mutation testing for Rust. Wraps cargo-mutants: kill rate, surviving-mutant evidence, kill-rate threshold gating. Detects tests that pass without asserting. Part of the dev-* verification collection.
Structured JSON reports for Rust verification tooling. Stable, versioned wire format with optional terminal, markdown, SARIF, and JUnit XML rendering. Foundation of the dev-* collection.
