Testlie documentation

Testlie is a testing toolkit for the parts of your app that talk to the outside world:

  • Email sandbox. Point the SMTP settings of your development, staging and CI environments at Testlie. Every message is captured and shown in a web UI, and nothing is ever delivered to the real recipients. Your team previews the HTML, reads headers and attachments, checks spam scores and email-client support, and asserts on messages from automated tests.
  • SMS sandbox. Capture text messages through a Twilio-compatible API and simulate delivery or failure without sending a real SMS. Get started with SMS.
  • HTTP request bins. Inspect outgoing HTTP calls, configure responses and test webhooks. Create a request bin.
  • Mock identity providers. Fake OIDC and SAML 2.0 identity providers for testing your app's single sign-on. Define test users with groups and custom claims, pick one on the login screen (or sign in automatically in CI), and inspect every request and token in an activity log.

Testlie is a hosted service at https://testlie.com: there is nothing to install. It also has sandboxes for WhatsApp, push notifications and voice calls, inbound deliveries to your app, mock social login and failure scenarios.

How it fits together

Piece What it does
Inbox A mailbox with its own SMTP username and password. Anything your app sends with those credentials lands here, whatever the recipient address.
Project An optional group of inboxes, for example one project per app with an inbox per environment.
Team Owns inboxes, identity providers, API keys and webhooks. Members are owners, admins or members.
API key Lets your tests and scripts call the REST API, for example to wait for an email.
Webhook An HTTP endpoint that is notified when mail arrives.
Mock IdP An OIDC and SAML identity provider with test users, at https://testlie.com/idp/<slug>.
