Testing Guidelines

Unit Tests

describe('AuthService', () => {
  describe('register', () => {
    it('should create user with hashed password', async () => {
      // Arrange
      const dto = { email: '[email protected]', password: 'SecurePass123!' };

      // Act
      const result = await authService.register(dto);

      // Assert
      expect(result.user.email).toBe(dto.email);
      expect(result.user.password).not.toBe(dto.password);
    });

    it('should reject duplicate email', async () => {
      // Arrange
      const dto = { email: '[email protected]', password: 'Pass123!' };

      // Act & Assert
      await expect(authService.register(dto)).rejects.toThrow('Email exists');
    });
  });
});
