+# Aura macOS Client Test Suite
+
+## Overview
+
+Comprehensive test suite for the Aura macOS client covering all core functionality including server management, profile management, identity operations, and connection retry logic.
+
+## Test Coverage
+
+### Unit Tests
+
+#### ServerManagerTests (12 tests)
+- ✅ CRUD operations (add, update, delete)
+- ✅ Recent servers sorting and limiting
+- ✅ Favorite servers filtering
+- ✅ Persistence across app restarts
+
+#### ProfileManagerTests (13 tests)
+- ✅ CRUD operations (create, update, delete)
+- ✅ Server linking (many-to-many relationships)
+- ✅ Recent profiles sorting and limiting
+- ✅ Biometric flag persistence
+- ✅ Keychain coordination
+
+#### UserIdentityTests (18 tests)
+- ✅ Ed25519 keypair generation
+- ✅ Data signing and signature verification
+- ✅ Keychain save/load operations
+- ✅ Profile import/export (JSON format)
+- ✅ Round-trip import/export validation
+- ✅ Invalid data handling
+- ✅ Display name management
+
+#### ConnectionRetryTests (8 tests)
+- ✅ Retry state management
+- ✅ Connection parameter preservation
+- ✅ Disconnect cleanup
+- ✅ Exponential backoff timing validation
+- ✅ Authentication state tracking
+
+### Integration Tests (6 tests)
+- ✅ Profile-server linking workflows
+- ✅ Multiple profiles with multiple servers
+- ✅ Import/export with server links
+- ✅ Keychain persistence across restarts
+- ✅ Full connection flow simulation
+- ✅ Data consistency validation
+
+## Running Tests
+
+### Quick Run
+```bash
+./run-tests.sh
+```
+
+### Manual Run
+```bash
+xcodebuild test \
+ -project Aura.xcodeproj \
+ -scheme Aura \
+ -destination 'platform=macOS' \
+ -enableCodeCoverage YES
+```
+
+### Run Specific Test Class
+```bash
+xcodebuild test \
+ -project Aura.xcodeproj \
+ -scheme Aura \
+ -destination 'platform=macOS' \
+ -only-testing:AuraTests/ServerManagerTests
+```
+
+### Run Specific Test
+```bash
+xcodebuild test \
+ -project Aura.xcodeproj \
+ -scheme Aura \
+ -destination 'platform=macOS' \
+ -only-testing:AuraTests/ServerManagerTests/testAddServer
+```
+
+## Test Reports
+
+After running `./run-tests.sh`, reports are generated in the `build/` directory:
+- `test-report.html` - Detailed test results
+- `coverage.txt` - Code coverage summary
+
+## CI/CD Integration
+
+Add to your CI pipeline:
+
+```yaml
+# GitHub Actions example
+- name: Run Tests
+ run: |
+ cd clients/macos
+ ./run-tests.sh
+```
+
+## Test Data Cleanup
+
+All tests use isolated storage keys and clean up after themselves:
+- `TestAuraServerProfiles` - Test server data
+- `TestAuraUserProfiles` - Test profile metadata
+- Keychain entries are created and deleted per test
+
+## Keychain Testing Notes
+
+Some tests require keychain access:
+- Non-biometric keychain tests run on all platforms
+- Biometric tests require Secure Enclave (physical Mac or simulator with biometric support)
+- Tests will skip biometric operations if Secure Enclave is unavailable
+
+## Adding New Tests
+
+1. Create test file in `AuraTests/`
+2. Import `@testable import Aura`
+3. Extend `XCTestCase` with `@MainActor` for async support
+4. Follow naming convention: `{Feature}Tests.swift`
+5. Add setup/teardown for test isolation
+6. Use descriptive test names: `test{Action}{Expected}`
+
+Example:
+```swift
+@MainActor
+final class MyFeatureTests: XCTestCase {
+ var feature: MyFeature!
+
+ override func setUp() async throws {
+ feature = MyFeature()
+ }
+
+ override func tearDown() async throws {
+ feature = nil
+ }
+
+ func testFeatureDoesExpectedThing() {
+ // Arrange
+ let input = "test"
+
+ // Act
+ let result = feature.process(input)
+
+ // Assert
+ XCTAssertEqual(result, "expected")
+ }
+}
+```
+
+## Coverage Goals
+
+- **Target**: 80%+ code coverage for new features
+- **Critical paths**: 100% coverage for security-related code (keychain, crypto)
+- **UI**: Integration tests for critical user flows
+
+## Troubleshooting
+
+### Tests fail with keychain errors
+- Ensure you're running on macOS (not iOS simulator)
+- Check keychain access permissions
+- Clean test data: `defaults delete com.aura.Aura`
+
+### Tests timeout
+- Increase timeout in test settings
+- Check for infinite loops or blocking operations
+
+### Flaky tests
+- Ensure proper test isolation (setup/teardown)
+- Avoid timing-dependent assertions
+- Use `XCTestExpectation` for async operations
