'''GNU/Linux Desktop Testing Project''' (GNU/LDTP) is aimed at producing high quality [[test automation]] framework and cutting-edge tools that can be used to test GNU/Linux Desktop and improve it. It uses the "Accessibility" libraries to poke through the application's user interface. The framework has tools to generate "AppMap" by reading through the user interface components of an application. The framework also has tools to record test-cases based on user-selection on the application.

The '''Linux Desktop Testing Project''' (LDTP) is a [[testing tool]] that uses computer [[Computer accessibility|assistive technology]]<ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/ |title=ldtp}}</ref> to automate [[graphical user interface]] (GUI) testing.<ref>{{cite web |url=http://www.h-online.com/open/news/item/LDTP-3-0-automates-GUI-testing-on-Linux-1660613.html |title=LDTP 3.0 automates GUI testing on Linux - The H Open: News and Features}}</ref> The GUI functionality of an application can be tested in [[Linux]], [[macOS]], [[Windows]], [[Oracle Solaris|Solaris]], [[FreeBSD]], and [[embedded system]] environments.<ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/ |title=ldtp}}</ref> The macOS version is named PyATOM,<ref>{{cite web |url=https://github.com/pyatom/pyatom |title=pyatom/pyatom - GitHub}}</ref> and the Windows version is Cobra.<ref>{{cite web |url=https://github.com/ldtp/cobra |title=ldtp/cobra - GitHub}}</ref> The LDTP is released as [[free and open-source software]] under the [[GNU Lesser General Public License]] (LGPL).

GNU/LDTP core framework uses "[[AppMap]]" and the recorded "test-cases" to test an application and gives the status of each test-case as output.

As of now, GNU/LDTP can test any accessibility-enabled [[GNOME]] application which are accessibility enabled, [[Mozilla]], [[OpenOffice.org]], any Swing-based [[Java (programming language)|Java]], application[[Qt (should have a UIsoftware)|Qt]] 4-based on swing) and [[KDE]] 4.0x applications.<ref>{{cite basedweb on QT 4|url=http://ldtp.freedesktop.0org/wiki/ (based on the press releases by KDE).|title=ldtp}}</ref>

LDTP is/was used by the following companies and organizations:<ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/FAQ/ |title=FAQ}}</ref>

==History==

LDTP version 0.1.0 was released in January 2005 and then showcased and discussed at GNOME Users And Developers European Conference ([[GUADEC]]) 2005. It was then used at the [[Google Summer of Code]] in 2006<ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/SoC/ |title=SoC}}</ref><ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/SoC06/ |title=SoC06}}</ref> for [[Tinderbox (software)|Tinderbox]] integration, [[Evolution (software)|Evolution]] automation, and LDTP regression suite under [[GNOME]] organization. Then again in 2007,<ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/SoC/ |title=SoC}}</ref><ref>{{cite web |url=http://ldtp.freedesktop.org/wiki/SoC07/ |title=SoC07}}</ref> it was used by the Mozilla Foundation for [[Firefox]] automation and [[Tinderbox (software)|Tinderbox]] integration.

==Example==

This is an example of how LDTP would test writing in [[gedit]]:

<syntaxhighlight lang="python">

#!/usr/bin/env python3

# The standard import stuff.

from ldtp import *

from ooldtp import context as locate

from time import sleep

# Here we open the app.

launchapp("gedit")

# Now we find it and make sure it is open.

gedit_win = locate("*gedit")

gedit_win.waittillguiexist()

# Now we type into gedit.

text_field = gedit_win.getchild("txt1")

text_field.enterstring("G'Day mate!")

# Save a picture to prove we did it.

imagecapture("*gedit", "/tmp/foo.png")

# Quit gedit.

quit = gedit_win.getchild("mnuQuit")

quit.selectmenuitem()

# Close without saving.

dont_save = locate("Question")

dont_save.waittillguiexist()

button = dont_save.getchild("btnClosewithoutSaving")

button.click()

# Wait until gedit is gone.

gedit_win.waittillguinotexist()

</syntaxhighlight>
