AUTOMATED TEST EXAMPLES
In this chapter we will demonstrate step by step how you can run automated tests straight
from the command-line. UCD-240 is also fully compatible with third-party test
management systems (e.g. NI TestStand). You can also integrate the C++ code into existing
test systems. Running automated tests from the command-line is the simplest option for test
automation as it does not require any coding or external Software. In these examples
automated tests were run using USB Type-C smartphone as a DUT.
First , we will showcase Unigraf’s Electrical Test feature by running Electrical Tests on Up
Face Port CC and VCONN pins. By measuring the actual voltages through USB-C
connector pins, we can ensure that all pins are functioning, and the soldering has been done
properly.
Second , we will run automated DP Alt Mode tests for both two and four lines to
make sure that the DUT is functional in both DP Alternate Modes. Third , we will perform
one CRC based video test (single frame video stability test). All different Electrical Tests
and CRC based video tests are available for configuration in UCD Console GUI under the
Source DUT testing tab.
Electrical Test • Up Face Port CC and VCONN
Before running the automated tests with UCD-240 it needs to be ensured that the Unigraf
Test Cable and DUT are connected. Detailed instructions for ensuring the connection can
be found from chapter 4.
