+### Running Tests
+
+We have two test suites:
+
+**1. Main Project Tests (ngit-grasp)**
+
 ```bash
-# Run tests
-cargo test
+# Run unit tests (no external dependencies)
+nix develop -c cargo test --lib
+
+# Run integration tests (tests our relay implementation)
+# First, start ngit-grasp relay in one terminal:
+NGIT_BIND_ADDRESS=127.0.0.1:7000 nix develop -c cargo run
+
+# Then in another terminal, run integration tests:
+nix develop -c cargo test --test announcement_tests --ignored
+
+# Or use the test script (starts relay automatically):
+./test_relay.sh
+```
 
-# Run compliance tests
-cargo test --test compliance
+**2. GRASP Audit Tool (grasp-audit)**
 
+The audit tool tests GRASP compliance of any relay (including ours or external ones).
+
+```bash
+# Enter grasp-audit directory
+cd grasp-audit
+
+# Run unit tests
+nix develop -c cargo test
+
+# Test against our ngit-grasp relay:
+# First, start ngit-grasp (in another terminal):
+cd .. && NGIT_BIND_ADDRESS=127.0.0.1:7000 nix develop -c cargo run
+
+# Then run audit:
+nix develop -c cargo run -- --url ws://127.0.0.1:7000
+
+# Or test against any external relay:
+nix develop -c cargo run -- --url wss://relay.example.com
+```
+
+### Development Commands
+
+```bash
 # Run with logging
-RUST_LOG=debug cargo run
+RUST_LOG=debug nix develop -c cargo run
 
 # Check code
-cargo clippy
-cargo fmt --check
+nix develop -c cargo clippy
+nix develop -c cargo fmt --check
 
-# Generate test coverage
-cargo tarpaulin --out Html
+# Generate test coverage (requires tarpaulin)
+nix develop -c cargo tarpaulin --out Html
 ```
 
+**Note:** Always use `nix develop` to ensure the correct build environment. See [docs/how-to/nix-flakes.md](docs/how-to/nix-flakes.md) for details.
