Simulated Teams desktop and mobile platforms for testing tab apps. Useful for CI testing scenarios.

This library expects you to bring your own authentication. This is done by providing an object or class with the following methods:

• getAccessToken
• getUser

A sample that uses teams-authenticator (MSAL helper library) is included: /src/authentication.example.ts.

This auth class is provided to Teams Tab Test Fixture one of three ways:

• [Recommended] Add a global property "window.AuthenticationProvider" to the page running the test fixture.
• If you're building this repository locally, you can add a module authentication.js to the root and it will be loaded
• Host the authentication.js file on a server and load it by passing "authScriptUrl" to startServer

Install the package from npm.

npm install teams-tab-test-fixture

In your project, require and run the test fixture server.

const { startServer, stopServer } = require('teams-tab-test-fixture');

startServer({
  appContext: {
    urlTemplate: 'https://localhost:8181?tenantId={tid}&groupId={groupId}'
  },
});

With the server running, you can access Teams Tab Test Fixture on https://localhost:8080

urlTemplate is a string that uses the same variable replacement signature as teams tab apps. It's the url that the nested iframe will be set to.
