DAC Plugin - Test suite
=======================

.. note::

User guide: :ref:`DAC Plugin user Guide<dac>`

The DAC plugin tests are a set of tests that are run to verify the DAC plugin in Scopy.

The following apply for all the test cases in this suite.
If the test case has special requirements, they will be listed in the test case section.

Setup environment:
-------------------

.. _adalm_pluto_emu_setup:

**AdalmPluto.Emu:**
- Open Scopy.
- Start the IIO-EMU process.
- Connect to the ADALM-Pluto device using the EMU dropdown.

.. _adalm_pluto_device_setup:

**AdalmPluto.Device:**
- Open Scopy.
- Connect the ADALM-Pluto device to the system.
- Connect to the ADALM-Pluto device in Scopy using USB/network backend.

**Depends on::**
- Test TST.PREFS.RESET

Prerequisites:
- Scopy v2.0.0 or later with DAC plugin installed on the system.
- Tests listed as dependencies are successfully completed.
- Reset .ini files to default using the Preferences "Reset" button.
