14.10Test structure

A clean API integration test might look like:

test('customer is mapped to Salesforce Account', async ({ request }) => {

  // Arrange
  const customer = makeCustomer();

  // Act
  const response = await createCustomer(request, customer);

  // Assert API
  expect(response.status()).toBe(201);

  // Assert target system
  const account =
    await salesforce.findAccount(customer.customerId);

  expect(account.Name).toBe(customer.companyName);
  expect(account.Phone).toBe(customer.phone);
});

This is simple and strong.
