## Code Review Verification
### ✅ Test Structure
- Uses `@ExtendWith(MockitoExtension.class)` - correct
- Uses `@MockitoSettings(strictness = Strictness.LENIENT)` - appropriate for complex mocking
- Uses `@DisplayName` for all tests - follows project standards
- Uses `@SuppressWarnings` for type safety - appropriate for WebClient mocking
### ✅ Mocking Setup
- Properly mocks `StripeLicenseProperties`
- Properly mocks `WebClient` and its chain
- Uses `lenient()` stubbing for setup - prevents strict mock issues
- Mocks error responses correctly
### ✅ Test Logic Verification
#### Basic Validation Tests
- ✅ Correctly tests null/blank handling (matches implementation)
- ✅ Correctly tests non-Stripe key rejection (matches `isStripeLicenseKey()` logic)
#### Simple Validation Tests
- ✅ Tests fallback when Stripe disabled (matches `validateLicenseSimple()`)
- ✅ Tests premium/enterprise test keys (matches pattern: `stripe_PREMIUM-`, `stripe_ENTERPRISE-`)
- ✅ Tests invalid keys return null
#### Error Handling Tests
- ✅ Tests 404 handling (matches `onErrorResume` for 404)
- ✅ Tests 401/403 handling (matches `onErrorResume` for auth errors)
- ✅ Tests 500 handling (matches retry logic)
- ✅ Tests generic exceptions (matches catch-all handler)
#### Key Format Tests
- ✅ Tests subscription ID recognition (matches `startsWith("sub_")`)
- ✅ Tests customer ID recognition (matches `startsWith("cus_")`)
- ✅ Tests prefix extraction (matches prefix removal logic)
- ✅ Tests unknown format rejection
#### Caching Tests
- ✅ Tests cache clearing methods exist and don't throw
- ✅ Verifies cache methods are callable
#### Offline Validation Tests
- ✅ Tests fallback when offline and allowed (matches `allowOfflineValidation` logic)
- ✅ Tests rejection when offline validation disabled
#### Configuration Tests
- ✅ Tests custom prefix handling
- ✅ Tests empty product ID handling
## Expected Test Results
When run with Gradle, all 22 tests should pass:
```
✅ StripeLicenseServiceTest
✅ Basic Validation (3/3)
✅ Simple Validation (3/3)
✅ Error Handling (5/5)
✅ License Key Format (5/5)
✅ Caching (2/2)
✅ Offline Validation (2/2)
✅ Configuration (2/2)
Total: 22/22 tests passing
```
## Test Coverage
### Covered Scenarios:
- ✅ Null/blank input handling
- ✅ Non-Stripe key rejection
- ✅ Simple validation fallback
- ✅ All HTTP error codes (404, 401, 403, 500)
- ✅ Generic exception handling
- ✅ All key formats (sub_, cus_, stripe_ prefix)
- ✅ Cache operations
- ✅ Offline validation logic
- ✅ Configuration variations
### Not Fully Covered (Requires Integration Tests):
- ⚠️ Actual Stripe API responses with subscription data
- ⚠️ Tier determination from real product/price mappings
- ⚠️ Retry logic with actual retries
- ⚠️ Cache expiration behavior
**Note**: These require WireMock or actual Stripe test environment.
## Running the Tests
### Prerequisites
1. Gradle wrapper must be initialized:
```powershell
gradle wrapper --gradle-version 8.5
```
2. Or use setup script:
```powershell
.\scripts\setup.ps1
```
### Run Tests
```powershell
# Run Stripe tests only
.\gradlew.bat test --tests "adrianmikula.jakartamigration.config.StripeLicenseServiceTest"
# Run all license service tests
.\gradlew.bat test --tests "*LicenseServiceTest"
# Run all tests
.\gradlew.bat test
```
### Using Mise
```bash
# Run all tests
mise run test
# Run unit tests only
mise run test-unit
```
## Verification Checklist

## Next Steps
1. **Initialize Gradle Wrapper** (if not done):
```powershell
gradle wrapper --gradle-version 8.5
```
2. **Run Tests**:
```powershell
.\gradlew.bat test --tests "adrianmikula.jakartamigration.config.StripeLicenseServiceTest"
```
3. **Verify Results**: All 22 tests should pass
