A test user is a user account associated with an app created for the purpose of testing the functionality of that application. You can use test users for manual or automated testing.

We allow you to access the test account via a login_url which allows you to directly login to the account. The login_url expires after one hour, but you easily refresh it to get a new login_url for the same test user. We also provide you an access_token for the test user so that you can take actions on behalf of the test user via the api.

An application can create up to 500 test users to start testing an application.

Currently one can only create and manage test user accounts via the API described below but in the near future we will be providing access to this via the developer app.

What is jsPerf?

jsPerf aims to provide an easy way to create and share test cases, comparing the performance of different JavaScript snippets by running benchmarks. For more information, see the FAQ.

Great place to do some JS tests and learn from others.
