+# Test Coverage and Quality Audit
+
+## 1. Coverage Analysis
+
+### Line Coverage
+
+- **Overall Line Coverage: 44.4%**
+
+The overall test coverage for the project is **44.4%**, which is below the recommended minimum of 80%. This indicates that a significant portion of the codebase is not covered by automated tests, increasing the risk of undetected bugs.
+
+### Untested Code
+
+The following files and functions have **0% test coverage** and should be prioritized for testing:
+
+- **`pkg/node/controller.go`**
+  - `NewController`
+  - `handleResponse`
+  - `sendRequest`
+  - `GetRemoteStats`
+  - `StartRemoteMiner`
+  - `StopRemoteMiner`
+  - `GetRemoteLogs`
+  - `GetAllStats`
+  - `PingPeer`
+  - `ConnectToPeer`
+  - `DisconnectFromPeer`
+
+- **`pkg/node/transport.go`**
+  - `IsDuplicate`
+  - `Mark`
+  - `Cleanup`
+  - `NewPeerRateLimiter`
+  - `Allow`
+  - `Start`
+  - `Stop`
+  - `OnMessage`
+  - `Connect`
+  - `Send`
+  - `Broadcast`
+  - `GetConnection`
+  - `handleWSUpgrade`
+  - `performHandshake`
+  - `readLoop`
+  - `keepalive`
+  - `removeConnection`
+  - `Close`
+  - `GracefulClose`
+  - `encryptMessage`
+  - `decryptMessage`
+  - `ConnectedPeers`
+
+- **`pkg/mining/xmrig.go`**
+  - `Uninstall`
+
+- **`pkg/node/dispatcher.go`**
+  - `DispatchUEPS`
+
+- **`pkg/node/identity.go`**
+  - `handleHandshake`
+  - `handleComputeRequest`
+  - `enterRehabMode`
+  - `handleApplicationData`
+
+## 2. Test Quality
+
+### Test Independence
+
+The existing tests appear to be isolated and do not share mutable state. However, the lack of comprehensive integration tests means that the interactions between components are not well-tested.
+
+### Test Clarity
+
+The test names are generally descriptive, but they could be improved by following a more consistent naming convention. The Arrange-Act-Assert pattern is not consistently applied, which can make the tests harder to understand.
+
+### Test Reliability
+
+The tests are not flaky and do not have any time-dependent failures. However, the lack of mocking for external dependencies means that the tests are not as reliable as they could be.
+
+## 3. Missing Tests
+
+### Edge Cases
+
+The tests do not cover a sufficient number of edge cases, such as null inputs, empty strings, and boundary values.
+
+### Error Paths
+
+The tests do not adequately cover error paths, which can lead to unhandled exceptions in production.
+
+### Security Tests
+
+There are no security tests to check for vulnerabilities such as authentication bypass or injection attacks.
+
+### Integration Tests
+
+The lack of integration tests means that the interactions between different components are not well-tested.
+
+## 4. Suggested Tests to Add
+
+### `pkg/node/controller.go`
+
+- `TestNewController`: Verify that a new controller is created with the correct initial state.
+- `TestHandleResponse`: Test that the controller correctly handles incoming responses.
+- `TestSendRequest`: Test that the controller can send requests and receive responses.
+- `TestGetRemoteStats`: Test that the controller can retrieve stats from a remote peer.
+- `TestStartRemoteMiner`: Test that the controller can start a miner on a remote peer.
+- `TestStopRemoteMiner`: Test that the controller can stop a miner on a remote peer.
+- `TestGetRemoteLogs`: Test that the controller can retrieve logs from a remote peer.
+- `TestGetAllStats`: Test that the controller can retrieve stats from all connected peers.
+- `TestPingPeer`: Test that the controller can ping a remote peer.
+- `TestConnectToPeer`: Test that the controller can connect to a remote peer.
+- `TestDisconnectFromPeer`: Test that the controller can disconnect from a remote peer.
+
+### `pkg/node/transport.go`
+
+- `TestTransportStartAndStop`: Test that the transport can be started and stopped correctly.
+- `TestTransportConnect`: Test that the transport can connect to a remote peer.
+- `TestTransportSendAndReceive`: Test that the transport can send and receive messages.
+- `TestTransportBroadcast`: Test that the transport can broadcast messages to all connected peers.
+- `TestTransportHandshake`: Test that the transport correctly performs the handshake with a remote peer.
+- `TestTransportEncryption`: Test that the transport correctly encrypts and decrypts messages.
+
+### `pkg/mining/xmrig.go`
+
+- `TestUninstall`: Test that the `Uninstall` function correctly removes the miner binary.
+
+### `pkg/node/dispatcher.go`
+
+- `TestDispatchUEPS`: Test that the `DispatchUEPS` function correctly dispatches incoming packets.
