+
+## Writing Tests
+
+### Unit Test Example
+
+```typescript
+import { validateAddress } from "@/utils/security";
+
+describe("validateAddress", () => {
+  it("should validate correct addresses", () => {
+    const result = validateAddress("0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb");
+    expect(result.valid).toBe(true);
+    expect(result.checksummed).toBeDefined();
+  });
+
+  it("should reject invalid addresses", () => {
+    const result = validateAddress("invalid");
+    expect(result.valid).toBe(false);
+    expect(result.error).toBeDefined();
+  });
+});
+```
+
+### Integration Test Example
+
+```typescript
+describe("Wallet Management Flow", () => {
+  it("should create wallet with valid configuration", async () => {
+    const owners = ["0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb"];
+    const threshold = 1;
+
+    // Validate owners
+    const validatedOwners = owners.map(owner => {
+      const validation = validateAddress(owner);
+      expect(validation.valid).toBe(true);
+      return validation.checksummed!;
+    });
+
+    // Validate threshold
+    expect(threshold).toBeGreaterThan(0);
+    expect(threshold).toBeLessThanOrEqual(validatedOwners.length);
+  });
+});
+```
+
+### Component Test Example
+
+```typescript
+import { render, screen } from "@testing-library/react";
+import WalletManager from "@/components/SmartWallet/WalletManager";
+
+describe("WalletManager", () => {
+  it("should render wallet list", () => {
+    render(<WalletManager />);
+    expect(screen.getByText("Wallets")).toBeInTheDocument();
+  });
+});
+```
+
+## Test Patterns
+
+### Mocking Providers
+
+```typescript
+class MockProvider extends ethers.providers.BaseProvider {
+  async getNetwork() {
+    return { chainId: 1, name: "mainnet" };
+  }
+  
+  async perform(method: string, params: any): Promise<any> {
+    throw new Error("Not implemented");
+  }
+}
+```
+
+### Testing Async Functions
+
+```typescript
+it("should handle async operations", async () => {
+  const result = await asyncFunction();
+  expect(result).toBeDefined();
+});
+```
+
+### Testing Error Cases
+
+```typescript
+it("should handle errors", async () => {
+  await expect(asyncFunction()).rejects.toThrow("Error message");
+});
+```
+
+### Testing Hooks
+
+```typescript
+import { renderHook } from "@testing-library/react";
+import { useSmartWallet } from "@/contexts/SmartWalletContext";
+
+it("should return wallet context", () => {
+  const { result } = renderHook(() => useSmartWallet());
+  expect(result.current.activeWallet).toBeDefined();
+});
+```
+
+## Test Categories
+
+### Unit Tests
+
+Test individual functions and utilities in isolation.
+
+**Location:** `__tests__/*.test.ts`
+
+**Examples:**
+- Security utilities
+- Encryption functions
+- Validation functions
+- Helper functions
+
+### Integration Tests
+
+Test complete workflows and component interactions.
+
+**Location:** `__tests__/integration/*.test.ts`
+
+**Examples:**
+- Wallet management flow
+- Transaction flow
+- Multi-sig approval flow
+
+### Security Tests
+
+Test security features and attack vectors.
+
+**Location:** `__tests__/security.test.ts`
+
+**Examples:**
+- XSS prevention
+- Replay attack prevention
+- Race condition prevention
+- Integer overflow prevention
+
+## Test Utilities
+
+### Setup File
+
+`jest.setup.js` configures:
+- Testing library matchers
+- Mock implementations
+- Global test utilities
+
+### Mock Implementations
+
+```typescript
+// Mock localStorage
+const localStorageMock = {
+  getItem: jest.fn(),
+  setItem: jest.fn(),
+  removeItem: jest.fn(),
+  clear: jest.fn(),
+};
+global.localStorage = localStorageMock;
+```
+
+## Best Practices
+
+### 1. Test Structure
+
+```typescript
+describe("Feature", () => {
+  describe("Sub-feature", () => {
+    it("should do something", () => {
+      // Arrange
+      const input = "value";
+      
+      // Act
+      const result = function(input);
+      
+      // Assert
+      expect(result).toBe(expected);
+    });
+  });
+});
+```
+
+### 2. Test Naming
+
+- Use descriptive test names
+- Start with "should"
+- Describe expected behavior
+
+```typescript
+// ✅ Good
+it("should validate correct addresses", () => {});
+
+// ❌ Bad
+it("test1", () => {});
+```
+
+### 3. Test Isolation
+
+- Each test should be independent
+- Don't rely on test execution order
+- Clean up after tests
+
+### 4. Test Coverage
+
+- Aim for >80% coverage
+- Test happy paths
+- Test error cases
+- Test edge cases
+
+### 5. Mocking
+
+- Mock external dependencies
+- Mock async operations
+- Mock browser APIs
+- Keep mocks simple
+
+## Continuous Integration
+
+Tests run automatically on:
+- Pull requests
+- Pushes to main/develop
+- Scheduled runs
+
+**CI Configuration:** `.github/workflows/ci.yml`
+
+**CI Steps:**
+1. Lint code
+2. Run tests
+3. Check coverage
+4. Build project
+5. Security audit
+
+## Debugging Tests
+
+### VS Code Debugging
+
+Create `.vscode/launch.json`:
+
+```json
+{
+  "version": "0.2.0",
+  "configurations": [
+    {
+      "type": "node",
+      "request": "launch",
+      "name": "Jest: current file",
+      "program": "${workspaceFolder}/node_modules/.bin/jest",
+      "args": ["${relativeFile}"],
+      "console": "integratedTerminal"
+    }
+  ]
+}
+```
+
+### Debugging Tips
+
+1. Use `console.log` for debugging
+2. Use `debugger` statement
+3. Run single test file
+4. Use `--verbose` flag
+5. Check test output carefully
+
+## Test Maintenance
+
+### Keeping Tests Updated
+
+- Update tests when code changes
+- Remove obsolete tests
+- Refactor tests regularly
+- Keep test data current
+
+### Test Performance
+
+- Keep tests fast (< 1 second each)
+- Use mocks for slow operations
+- Parallelize when possible
+- Avoid unnecessary setup
+
+## Common Issues
+
+### Tests Failing
+
+1. Check error messages
+2. Verify test data
+3. Check mocks
+4. Review recent changes
+5. Clear cache: `rm -rf node_modules/.cache`
+
+### Coverage Issues
+
+1. Check uncovered lines
+2. Add missing tests
+3. Review coverage report
+4. Exclude unnecessary files
+
+### Flaky Tests
+
+1. Identify timing issues
+2. Add proper waits
+3. Use stable selectors
+4. Avoid race conditions
