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).

The LDTP can generate an "AppMap" by finding out what widgets applications use.{{Fact|date=April 2007}} The framework can also record test cases by watching what a user clicks on.{{Fact|date=April 2007}} The LDTP framework then uses this "AppMap" and the recorded test cases to test applications. Using this tool, the GUI functionality of an application can be tested in Linux, Solaris, FreeBSD and embedded environment [[Linux GUI Application Testing]].

LDTP can test any accessibility-enabled [[GNOME]] application, [[Mozilla]], [[OpenOffice.org]], any Swing-based [[Java (programming language)|Java]] application and should be able to test, [[Qt toolkit(software)|Qt]] 4.0-based and [[KDE]] 4.x applications.<ref>{{cite inweb the|url=http://ldtp.freedesktop.org/wiki/ future if a KDE press release{{Fact|datetitle=May 2007ldtp}} is correct.</ref>

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

The LDTP is released under the [[GPL]] and [[LGPL]].

==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>
