Emergency Functions Test Suite

Overview​

The emergency functions test suite (emergency-functions.spec.ts) validates the KagePool system's emergency operations and safety mechanisms, ensuring proper handling of critical situations and system recovery.

Emergency Operations​

Test Categories​

Emergency Controls​

Emergency Control Test Cases

Emergency Pause​

  • Description: Tests emergency pause functionality
  • Key Assertions:
    • Immediate operation halt
    • State preservation
    • Access control
    • Event emission

Emergency Recovery​

  • Description: Tests system recovery procedures
  • Key Assertions:
    • State restoration
    • Fund recovery
    • Access validation
    • Operation resumption

Safety Mechanisms​

Safety Test Cases

Circuit Breakers​

  • Description: Tests automatic safety triggers
  • Key Assertions:
    • Threshold detection
    • Automatic pause
    • Alert generation
    • Recovery initiation

Manual Interventions​

  • Description: Tests manual emergency controls
  • Key Assertions:
    • Admin controls
    • Override functions
    • State management
    • Access restrictions

Implementation Details​

Test Configuration​

interface EmergencyConfig {
  pauseTimeout: number;
  recoveryDelay: number;
  thresholds: {
    gas: BigNumber;
    time: number;
    attempts: number;
  };
}

const EMERGENCY_CONFIG: EmergencyConfig = {
  pauseTimeout: 3600, // 1 hour
  recoveryDelay: 86400, // 24 hours
  thresholds: {
    gas: parseEther("1"),
    time: 300, // 5 minutes
    attempts: 3,
  },
};

Emergency Test Cases

Emergency Pause Flow​

describe("Emergency Pause", () => {
  it("should pause all operations immediately", async () => {
    // Test implementation
  });

  it("should preserve system state", async () => {
    // Test implementation
  });
});

Recovery Flow​

describe("Emergency Recovery", () => {
  it("should restore system state safely", async () => {
    // Test implementation
  });

  it("should handle fund recovery", async () => {
    // Test implementation
  });
});

Implementation Notes​

Key Functions​

// Emergency controls
function emergencyPause() external onlyAdmin;

function emergencyResume() external onlyAdmin;

// Recovery operations
function emergencyWithdraw(uint256 poolId) external;

function recoverFunds(address token) external onlyAdmin;

// Safety checks
function checkSafetyThresholds() internal view;

function validateRecoveryState() internal view;

Test Utilities​

  • Time manipulation
  • State verification
  • Event validation
  • Access control

Monitoring and Verification​

Emergency Events​

event EmergencyPaused(
    address indexed admin,
    uint256 timestamp
);

event EmergencyRecovery(
    address indexed admin,
    uint256 poolId,
    uint256 amount
);

event SafetyThresholdBreached(
    string threshold,
    uint256 value,
    uint256 limit
);

State Verification​

  • System status
  • Fund balances
  • Access rights
  • Recovery state

Error Handling​

Emergency Errors​

error EmergencyPauseActive();
error RecoveryInProgress();
error InvalidRecoveryState();
error UnauthorizedEmergencyAction();

Recovery Procedures​

  • State restoration
  • Fund recovery
  • Access reset
  • Operation resume

Safety Patterns​
