A computing system may include a client computing device configured to execute a software application with an associated GUI. The GUI includes fields, and each field is to hold a text string. The computing system may include a GUI testing device in communication with the client computing device and configured to execute a testing framework for interacting with the software application to generate versions of the GUI, each of the versions being in a different language, and defining expected text strings in the fields. The GUI testing device may be configured to extract the fields from the versions of the GUI, perform OCR processing on the fields to generate actual text strings, and compare the actual text strings with the expected text strings.
