FAQPage Schema
How do I verify email delivery and content during local development?▼

Verify email delivery by polling a local inbox capture service for messages produced by app actions like signup or password reset, then extracting links or tokens to assert content.

Can I extract verification links and tokens from signup emails in automated tests?▼

Yes, extract verification links, tokens, or text from captured email content during automated testing workflows to perform assertions on signup, invite, and notification messages.

How do I poll a local inbox for messages triggered by password reset flows?▼

Poll a local inbox for password reset messages by configuring a base URL and polling interval to locate captured messages, then extract the reset tokens for test assertions.

Does this email testing approach support local inbox tools other than Mailpit?▼

The behavior specifies clear fallbacks for unsupported local inbox tools, ensuring robust email testing workflows even when switching away from the Mailpit local inbox capture service.

Why are my automated email tests failing to find captured messages?▼

Tests may fail if polling intervals are too short or the configured base URL is incorrect; ensure your local inbox capture service is running and properly receiving triggered app emails.
