Python module tkinter GUI testing

Mon 20 February 2023 Python python / cross-platform / tkinter / GUI testing

Overview

• installation: see https://arrizza.com/setup-common

Summary

This module contains a set of simple base classes that can be used for test or verification purposes on GUIs based on Tkinter.

A test harness can connect to this class using a TCPIP socket and get the current screen content, press an x,y coordinate, and invoke a menu item.

The typical scenario is to create a Tkinter GUI app and add the gui-api-tkinter server into it. Then a test harness is built using gui_api_harness and that is used by pytest (or whatever other test driver you wish) to run tests against the GUI.

For a more detailed description of the available commands and responses see gui_api.md

Scripts

• See Quick Start for information on using scripts.
• See xplat-utils submodule for information on the submodule.

Sample code

See the sample directory for a sample client and server. Use doit script to run the sample server.

./doit

This runs the code in the sample directory. The gui subdirectory contains a sample Tkinter GUI app which has some buttons and labels on it. The test harness is then used to press buttons on the GUI and check that the GUI perform s the expected behavior. The file sample/test_gui.py runs those tests.

The pom/ subdirectory holds Page Object Model classes to simplify the interactions between the test_gui code and the GUI app.

For a more complex example, see ./ver directory. Invoke those tests using:

./do_ver
./do_ver -k tp001   # for the first test protocol
# etc.
