TestCafe email and OTP testing
Use MailSlurp in TestCafe tests to create inboxes, wait for verification emails, and extract OTP codes.
MailSlurp fits TestCafe when TestCafe drives the browser and the MailSlurp JavaScript SDK manages inbox state. A common pattern is to create a fresh inbox for the test, submit inbox.emailAddress in the sign-up form, wait for the verification email, extract the code, and type it back into the UI.
Install
npm install --save mailslurp-client
Create an inbox with the JavaScript SDK
// create an inbox
const inbox = await mailslurp.inboxController.createInboxWithDefaults();
expect(inbox.emailAddress).toMatch(/.+@.+/);
Example TestCafe OTP flow
import { MailSlurp } from "mailslurp-client";
import { Selector } from "testcafe";
const mailslurp = new MailSlurp({ apiKey: process.env.API_KEY });
fixture`Sign up`.page`https://your-app.example/sign-up`;
test("completes email OTP verification", async (t) => {
const inbox = await mailslurp.createInbox();
await t
.typeText('input[name="email"]', inbox.emailAddress)
.typeText('input[name="password"]', "correct horse battery staple")
.click('button[type="submit"]');
const email = await mailslurp.waitController.waitForLatestEmail({
inboxId: inbox.id,
timeout: 120000,
unreadOnly: true,
});
const match = await mailslurp.emailController.getEmailContentMatch({
emailId: email.id,
contentMatchOptions: {
pattern: "(?:verification code|OTP|code)[:\\s-]*(\\d{6})",
},
});
await t
.typeText('input[name="verificationCode"]', match.matches[1])
.click('button[type="submit"]')
.expect(Selector('[data-test="dashboard"]').exists)
.ok();
});
