An integration test caught the bug and failed +2. The test was removed instead of being fixed ("test deletion culture") +3. Only a unit test was added, which didn't test end-to-end behavior +4. The bug shipped in production, preventing mesh topology formation + +**Lesson**: Tests that fail are telling us something important. Never delete a failing test without understanding the root cause. + +## Test-Driven Development (TDD) Requirements + +### For Network/Topology/Routing Changes + +Any changes to these critical areas MUST follow TDD: +- `crates/core/src/ring/` +- `crates/core/src/topology/` +- `crates/core/src/operations/connect.rs` +- `crates/core/src/node/network_bridge/` + +**Process:** +1. Write integration test demonstrating the issue or new behavior +2. Verify test **fails** (Red) +3. Implement the fix +4. Verify test **passes** (Green) +5. Refactor if needed +6. Run full test suite before creating PR + +**Example:** +```rust +// tests/connectivity.rs + +/// Regression test for issue #XXXX +/// +/// Previously, peers with only gateway connections couldn't discover other peers +/// because routing skip_list prevented using the gateway to find peers. +#[tokio::test] +async fn test_mesh_formation_through_gateway() -> TestResult { + // Test demonstrates the bug exists + // Implementation fixes it + // Test now passes +} +``` + +## Test Deletion Policy + +### NEVER Delete a Test Unless: + +- [ ] **Root cause fully understood** - Document in GitHub issue with `test-coverage` label +- [ ] **Alternative coverage proven** - Show equivalent or better test exists +- [ ] **Two-developer approval** - Requires review from two different developers +- [ ] **Issue created** - Tag with `test-coverage-gap` explaining why test was removed + +### If a Test Fails: + +1. **DO NOT** immediately disable or remove it +2. **DO** investigate why it's failing - this is a critical signal +3. **DO** create an issue if you can't fix it immediately +4. **DO** use `#[ignore]` with `TODO-MUST-FIX` comment (blocks commits via pre-commit hook) + +```rust +// TODO-MUST-FIX: Test reveals routing issue when peers have few connections +#[tokio::test] +#[ignore = "Investigating routing failure - see TODO-MUST-FIX above"] +async fn test_that_revealed_a_bug() -> TestResult { + // ... +} +``` + +## Critical Integration Tests + +These tests MUST exist and pass before any release: + +### Network Topology Tests (`tests/connectivity.rs`) + +- `test_basic_gateway_connectivity` - Verify gateway accepts connections +- `test_gateway_reconnection` - Verify reconnection after disconnect +- `test_three_node_network_connectivity` - **Verify p2p mesh formation** ⚠️ CRITICAL + + This test prevented a 4-month regression when it was wrongly removed. + +### Contract Operation Tests (`tests/operations.rs`) + +- `test_put_contract` - Verify contract storage +- `test_get_contract` - Verify contract retrieval +- `test_update_contract` - Verify state updates +- `test_subscribe_contract` - Verify subscriptions work + +### Connection Maintenance Tests + +These verify the network self-heals and maintains optimal topology: + +- Periodic maintenance runs (every 60s in production, 2s in tests) +- Topology adjustments create new connections +- Failed connections are pruned +- Network converges to mesh topology + +## Pre-Release Testing Checklist + +Before ANY release, ALL of these must pass: + +```bash +# 1.
