Developers: Integrate Temporary Emails in QA & Automation
Practical examples for using temporary emails in CI, end-to-end tests, and local QA workflows.
Updated August 2025 • 10 min read
Playbook
- Generate a temp address before each test
- Run signup or verification flow against your app
- Poll the inbox page for expected email arrival
- Parse links or codes and complete flows
- Let the inbox auto-expire after 10 minutes
Example: Cypress E2E
// cypress/e2e/signup.cy.ts
describe('Signup with temporary email', () => {
it('completes signup and verifies email', () => {
// 1) Visit OneTimeEmail to generate inbox
cy.visit('https://onetimeemail.net');
cy.contains('Generate Your Inbox').click();
// 2) Capture generated address from the UI (example selector)
cy.get('[data-testid="generated-email"]').invoke('text').as('tempEmail');
// 3) Use it to sign up in your app
cy.get('@tempEmail').then((email) => {
cy.visit('https://yourapp.example.com/signup');
cy.get('input[name="email"]').type(email as string);
cy.get('input[name="password"]').type('StrongPassword123!');
cy.contains('Create account').click();
});
// 4) Return to inbox and wait for email
cy.contains('Inbox').click();
cy.contains('Verification').should('be.visible');
// 5) Open email and click verify link
cy.contains('Verification').click();
cy.get('a').contains('Verify').then(($a) => {
const href = $a.prop('href');
cy.visit(href as string);
});
});
});
CI Tips
- • Run tests serially for email flows to avoid timing conflicts
- • Use unique test IDs per run to disambiguate inboxes
- • Store verification links in CI logs for debugging
- • Add retries with exponential backoff when polling inbox
