Provision real numbers for end-to-end SMS tests

Assign a phone number to each environment, country, or test run. Trigger your product's signup, login, MFA enrollment, or account recovery challenge, then keep the phone identity and received message attached to the test result.

await page.click('[data-test="sign-up-create-account-button"]');
// wait for verification code
const sms = await mailslurp.waitController.waitForLatestSms({
  waitForSingleSmsOptions: {
    phoneNumberId: phone.id,
    unreadOnly: true,
    timeout: 30_000,
  }
})
// extract the confirmation code (so we can confirm the user)
const code = /([0-9]{6})$/.exec(sms.body)?.[1]!!;

MailSlurp (examples)

const sms = await mailslurp.waitController.waitForLatestSms({
  waitForSingleSmsOptions: {
    phoneNumberId: phone.id,
    timeout: 30_000,
    unreadOnly: true,
  },
});
expect(sms.body).toContain('Here is your code');
expect(sms.fromNumber).toEqual('+13252527014');

Receive the OTP, parse the code, and assert the verified state

Wait for the inbound SMS, extract the one-time code, submit it through the browser or API flow, and fail clearly when delivery is late, the template changes, or retry controls allow the wrong code.

Release gate

Gate SMS verification before it ships

Run phone number allocation, SMS receipt, OTP extraction, and browser completion checks in CI so authentication releases fail with useful evidence instead of timing noise.

SMS and OTP verification API workflows MailSlurp supports

Turn SMS verification into a repeatable API flow: provision a number, trigger a challenge, receive the SMS, parse the OTP, submit it, and capture the final auth outcome.

Unify OTP verification checks

Use one workflow for SMS OTP, email fallback, magic-link recovery, and MFA verification instead of splitting auth evidence across tools.
