Tests

The MAP repo holds 2,889 tests across 262 test files. The engine itself has 716 lines of test in engine/core/src/tests.rs covering the full 8-stage pipeline.

Where tests live

Running

# Everything
cargo test --workspace --all-features

# Just the engine
cargo test -p map-core

# A specific protocol
cargo test -p mind-lib

# With logs
RUST_LOG=debug cargo test -p map-core -- --nocapture

Feature-gated tests

Some test groups run only under specific features:

# Native adapter (default for prod)
cargo test --features native-adapter

# WASM adapter (excludes tokio rt-multi-thread)
cargo test --features wasm-adapter --no-default-features

# Production storage (postgres + redis)
cargo test --features production-storage

Key test groups in engine/core/src/tests.rs

• pipeline_stages — each stage in isolation, then in sequence
• rate_limiter_behavior — token bucket exhaustion, refill, multi-tenant isolation
• security_gating — hierarchical wildcard matching across all three levels
• circuit_breaker — full CLOSED → OPEN → HALF_OPEN cycle with backoff
• load_balancer_failover — endpoint selection under partial failure
• audit_pipeline_async — non-blocking writes, sink failure, disk-backed buffer drain
• router_lru_semantics — cache hit/miss, eviction safety with outstanding invocations
• error_mapping — ProtocolError → CoreError for every variant

Property-based tests

The audit chain integrity tests use proptest:

• Inserting N random events and replaying produces an identical chain head
• Concurrent inserts from M tasks produce a consistent chain regardless of ordering
• A truncation followed by replay restores the same chain head

Continuous integration

CI runs:

1. cargo fmt --check
2. cargo clippy --workspace --all-features -- -D warnings -W clippy::unwrap_used
3. cargo test --workspace --all-features --no-fail-fast
4. cargo bench -p mind-lib (regression checks)
5. WASM build: cargo build --features wasm-adapter --no-default-features
6. Docker build of Dockerfile.mim (sanity check on the deploy variant)

A failing clippy lint blocks merge — particularly clippy::unwrap_used since the codebase forbids unwrap() in production paths.
