suggested regression tests

demo-monorepo/tests/regression/cascade-auth.spec.ts// jest
describe('processCheckout authentication', () => {
  it('should reject invalid tokens', async () => {
    const invalidToken = 'invalid';
    await expect(processCheckout(invalidToken, 100)).rejects.toThrow('Invalid authentication token');
  });
});
demo-monorepo/tests/regression/cascade-auth.spec.ts// jest
describe('validatePayment authentication', () => {
  it('should return false for invalid tokens', () => {
    const invalidToken = 'invalid';
    const result = validatePayment(invalidToken, 'credit_card');
    expect(result).toBe(false);
  });
});
/e

missing coverage

  • services/billing/checkout.tsprocessCheckout with invalid token should throw error
  • services/billing/checkout.tsvalidatePayment with invalid token should return false
  • services/billing/invoice.tsgenerateInvoice with invalid token should throw error
  • services/auth/index.tsrefreshToken with invalid token should return null
