Email Service (367 lines, 21 tests): - Send email with Mailgun integration - Password reset email template - Email verification template - Welcome email with features - HTML stripping for plain text - Configuration handling (US/EU regions) - Error handling and logging 2. Notifications Service (682 lines, 35 tests): - Smart notification suggestions with pattern analysis - Feeding/diaper/sleep pattern analysis - Medication reminders with scheduling - Milestone detection (2, 4, 6, 9, 12, 18, 24, 36 months) - Anomaly detection (feeding/sleep patterns) - Growth tracking reminders - Notification CRUD operations - Status management (pending/sent/read/dismissed/failed) - Bulk operations (markAllAsRead, cleanup) Total: 1,049 lines, 56 test cases 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .../src/common/services/email.service.spec.ts | 367 ++++++++++ .../notifications.service.spec.ts | 682 ++++++++++++++++++ 2 files changed, 1049 insertions(+) create mode 100644 maternal-app/maternal-app-backend/src/common/services/email.service.spec.ts create mode 100644 maternal-app/maternal-app-backend/src/modules/notifications/notifications.service.spec.ts diff --git a/maternal-app/maternal-app-backend/src/common/services/email.service.spec.ts b/maternal-app/maternal-app-backend/src/common/services/email.service.spec.ts new file mode 100644 index 0000000..c277a2a --- /dev/null +++ b/maternal-app/maternal-app-backend/src/common/services/email.service.spec.ts @@ -0,0 +1,367 @@ +import { Test, TestingModule } from '@nestjs/testing'; +import { ConfigService } from '@nestjs/config'; +import { EmailService, EmailOptions, PasswordResetEmailData, EmailVerificationData } from './email.service'; + +describe('EmailService', () => { + let service: EmailService; + let configService: ConfigService; + let mockMailgunClient: any; + + const mockConfigService = { + get: jest.fn((key: string, defaultValue?: any) => { + const config: Record = { + MAILGUN_API_KEY: 'test-api-key', + MAILGUN_DOMAIN: 'test.mailgun.org', + MAILGUN_REGION: 'us', + EMAIL_FROM: 'noreply@test.com', + EMAIL_FROM_NAME: 'Test App', + APP_URL: 'http://localhost:3000', + }; + return config[key] ?? defaultValue; + }), + }; + + beforeEach(async () => { + // Reset mocks + jest.clearAllMocks(); + + // Mock Mailgun client + mockMailgunClient = { + messages: { + create: jest.fn().mockResolvedValue({ id: 'test-message-id' }), + }, + }; + + // Mock Mailgun module + jest.mock('mailgun.js', () => { + return jest.fn().mockImplementation(() => ({ + client: jest.fn().mockReturnValue(mockMailgunClient), + })); + }); + + const module: TestingModule = await Test.createTestingModule({ + providers: [ + EmailService, + { + provide: ConfigService, + useValue: mockConfigService, + }, + ], + }).compile(); + + service = module.get(EmailService); + configService = module.get(ConfigService); + + // Inject mock mailgun client + (service as any).mailgunClient = mockMailgunClient; + (service as any).mailgunDomain = 'test.mailgun.org'; + }); + + it('should be defined', () => { + expect(service).toBeDefined(); + }); + + describe('sendEmail', () => { + it('should send email successfully with Mailgun', async () => { + const emailOptions: EmailOptions = { + to: 'user@example.com', + subject: 'Test Email', + html: '
