await mailslurp.sendEmail(inbox.id, {
  to: [inbox.emailAddress],
  body: 'Hi. Your code is "123456"',
});

// fetch an email
const email = await mailslurp.waitForLatestEmail(inbox.id);

// execute a regular express capture group on the body and
// destructure the matching group into a variable
const [_, verificationCode] =
  /your code is "([0-9]{6})"/gi.exec(email.body) ?? [];
expect(verificationCode).toEqual('123456');

// do something with code like verifying an account
// myApp.confirmUser(verificationCode);

Why testing with real messages matters

Test critical paths
What happens if a user can't sign up and login to your app? You won't know unless you test the process with real email addresses. Automate your QA testing using MailSlurp to find critical bugs before they affect customers.
Never send a broken email again
Capture outbound emails before they reach customers. Verify email content and detect exceptions that can't be found with unit tests or mocks. Stop embarrassing emails before they are sent using MailSlurp.
Instant test accounts
Spin up test accounts in automated environments using unique throw-away emails and phone numbers. Capture verification codes and password reset links during QA.
