Test Servers
============

If you wish to test your application in a separate environment, Pyrogram is able to authorize your account into
Telegram's test servers without hassle. All you need to do is start a new session (e.g.: "my_account_test") using
``test_mode=True``:

.. code-block:: python

    from pyrogram import Client

    with Client("my_account_test", test_mode=True) as app:
        print(app.get_me())

.. note::

    If this is the first time you login into test servers, you will be asked to register your account first.
    Don't worry about your contacts and chats, they will be kept untouched inside the production environment;
    accounts authorized on test servers reside in a different, parallel instance of a Telegram database.

Test Mode in Official Apps
--------------------------

You can also login yourself into test servers using official desktop apps, such as Webogram and TDesktop:

- **Webogram**: Login here: https://web.telegram.org/?test=1
- **TDesktop**: Hold ``Alt+Shift`` and right click on "Add account", then choose "Test server".

Test Numbers
------------

Beside normal numbers, the test environment allows you to login with reserved test numbers.
Valid phone numbers follow the pattern ``99966XYYYY``, where ``X`` is the DC number (1 to 3) and ``YYYY`` are random
numbers. Users with such numbers always get ``XXXXX`` as the confirmation code (the DC number, repeated five times).

.. important::

    Do not store any important or private information in such test users' accounts; anyone can make use of the
    simplified authorization mechanism and login at any time.
