NAME X11::GUITest - Provides GUI testing/interaction facilities. Developed by Dennis K. Paulsen VERSION 0.22 Updates are made available at the following sites: http://sourceforge.net/projects/x11guitest (Primary) http://www.freshmeat.net (Linked) http://www.cpan.org (Secondary) Please consult 'docs/Changes' for the list of changes between module revisions. DESCRIPTION This Perl package is intended to facilitate the testing of GUI applications by means of user emulation. It can be used to test/interact with GUI applications; which have been built upon the X library or toolkits (i.e., GTK+, Xt, Qt, Motif, etc.) that "wrap" the X library's functionality. DEPENDENCIES An X server with the XTest extensions enabled. This seems to be the norm. If it is not enabled, it usually can be by modifying the X server configuration (i.e., XF86Config). The standard DISPLAY environment variable is utilized to determine the host, display, and screen to work with. By default it is usually set to ":0.0" for the localhost. However, by altering this variable one can interact with applications under a remote host's X server. To change this from a terminal window, one can utilize the following basic syntax: export DISPLAY=:. Please note that under most circumstances, xhost will need to be executed properly on the remote host as well. There is a known incompatibility between the XTest and Xinerama extensions, which causes the XTestFakeMotionEvent() function to misbehave. When the Xinerama (X server) extension is turned on, this (Perl) extension has been modified to allow one to invoke an alternative function. See Makefile.PL for details. INSTALLATION perl Makefile.PL make make test make install SYNOPSIS For additional examples, please look under the 'eg/' sub-directory from the installation folder. use X11::GUITest qw/ StartApp WaitWindowViewable SendKeys /; # Start gedit application StartApp('gedit'); # Wait for application window to come up and become viewable. my ($GEditWinId) = WaitWindowViewable('gedit'); if (!$GEditWinId) { die("Couldn't find gedit window in time!"); } # Send text to it SendKeys("Hello, how are you?\n"); # Close Application (Alt-f, q). SendKeys('%(f)q'); # Handle gedit's Question window if it comes up when closing. Wait # at most 5 seconds for it. if (WaitWindowViewable('Question', undef, 5)) { # DoN't Save (Alt-n) SendKeys('%(n)'); } FUNCTIONS Parameters enclosed within [] are optional. If there are multiple optional parameters available for a function and you would like to specify the last one, for example, you can utilize undef for those parameters you don't specify. REGEX in the documentation below denotes an item that is treated as a regular expression. For example, the regex "^OK$" would look for an exact match for the word OK. FindWindowLike TITLEREGEX [, WINDOWIDSTARTUNDER] Finds the window Ids of the windows matching the specified title regex. Optionally one can specify the window to start under; which would allow one to constrain the search to child windows of that window. An array of window Ids is returned for the matches found. An empty array is returned if no matches were found. my @WindowIds = FindWindowLike('gedit'); # Only worry about first window found my ($WindowId) = FindWindowLike('gedit'); WaitWindowLike TITLEREGEX [, WINDOWIDSTARTUNDER] [, MAXWAITINSECONDS] Waits for a window to come up that matches the specified title regex. Optionally one can specify the window to start under; which would allow one to constrain the search to child windows of that window. One can optionally specify an alternative wait amount in seconds. A window will keep being looked for that matches the specified title regex until this amount of time has been reached. The default amount is defined in the DEF_WAIT constant available through the :CONST export tag. If a window is going to be manipulated by input, WaitWindowViewable is the more robust solution to utilize. An array of window Ids is returned for the matches found. An empty array is returned if no matches were found. my @WindowIds = WaitWindowLike('gedit'); # Only worry about first window found my ($WindowId) = WaitWindowLike('gedit'); WaitWindowLike('gedit') or die("gedit window not found!"); WaitWindowViewable TITLEREGEX [, WINDOWIDSTARTUNDER] [, MAXWAITINSECONDS] Similar to WaitWindow, but only recognizes windows that are viewable. When GUI applications are started, their window isn't necessarily viewable yet, let alone available for input, so this function is very useful. Likewise, this function will only return an array of the matching window Ids for those windows that are viewable. An empty array is returned if no matches were found. WaitWindowClose WINDOWID [, MAXWAITINSECONDS] Waits for the specified window to close. One can optionally specify an alternative wait amount in seconds. The window will keep being checked to see if it has closed until this amount of time has been reached. The default amount is defined in the DEF_WAIT constant available through the :CONST export tag. zero is returned if window is not gone, non-zero if it is gone. ClickWindow WINDOWID [, X Offset] [, Y Offset] [, Button] Clicks on the specified window with the mouse. Optionally one can specify the X offset and Y offset. By default, the top left corner of the window is clicked on, with these two parameters one can specify a different position to be clicked on. One can also specify an alternative button. The default button is M_LEFT, but M_MIDDLE and M_RIGHT may be specified too. Also, you could use the logical Id for the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through the :CONST export tag. zero is returned on failure, non-zero for success GetWindowFromPoint X, Y [, SCREEN] Returns the window that is at the specified point. If no screen is given, it is taken from the value given when opening the X display. zero is returned if there are no matches (i.e., off screen). IsChild PARENTWINDOWID, WINDOWID Determines if the specified window is a child of the specified parent. zero is returned for false, non-zero for true. QuoteStringForSendKeys STRING Quotes {} characters in the specified string that would be interpreted as having special meaning if sent to SendKeys directly. This function would be useful if you had a text file in which you wanted to use each line of the file as input to the SendKeys function, but didn't want any special interpretation of the characters in the file. Returns the quoted string, undef is returned on error. # Quote ~, %, etc. as {~}, {%}, etc for literal use in SendKeys. SendKeys( QuoteStringForSendKeys('Hello: ~%^(){}+#') ); StartApp COMMANDLINE Uses the shell to execute a program. This function returns as soon as the program is called. Useful for starting GUI applications and then going on to work with them. zero is returned on failure, non-zero for success StartApp('gedit'); RunApp COMMANDLINE Uses the shell to execute a program until its completion. Return value will be application specific, however -1 is returned to indicate a failure in starting the program. RunApp('/work/myapp'); ClickMouseButton BUTTON Clicks the specified mouse button. Available mouse buttons are: M_LEFT, M_MIDDLE, M_RIGHT. Also, you could use the logical Id for the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through the :CONST export tag. zero is returned on failure, non-zero for success. DefaultScreen Returns the screen number specified in the X display value used to open the display. ScreenCount Returns the number of screens in the X display specified when opening it. SetEventSendDelay DELAYINMILLISECONDS Sets the milliseconds of delay between events being sent to the X display. It is usually not a good idea to set this to 0. Please note that this delay will also affect SendKeys. Returns the old delay amount in milliseconds. GetEventSendDelay Returns the current event sending delay amount in milliseconds. SetKeySendDelay DELAYINMILLISECONDS Sets the milliseconds of delay between keystrokes. Returns the old delay amount in milliseconds. GetKeySendDelay Returns the current keystroke sending delay amount in milliseconds. GetWindowName WINDOWID Returns the window name for the specified window Id. undef is returned if name could not be obtained. # Return the name of the window that has the input focus. my $WinName = GetWindowName(GetInputFocus()); SetWindowName WINDOWID, NAME Sets the window name for the specified window Id. zero is returned on failure, non-zero for success. GetRootWindow [SCREEN] Returns the Id of the root window of the screen. This is the top/root level window that all other windows are under. If no screen is given, it is taken from the value given when opening the X display. GetChildWindows WINDOWID Returns an array of the child windows for the specified window Id. If it detects that the window hierarchy is in transition, it will wait half a second and try again. MoveMouseAbs X, Y [, SCREEN] Moves the mouse cursor to the specified absolute position in the optionally given screen. If no screen is given, it is taken from the value given when opening the X display. Zero is returned on failure, non-zero for success. GetMousePos Returns an array containing the position and the screen (number) of the mouse cursor. my ($x, $y, $scr_num) = GetMousePos(); PressMouseButton BUTTON Presses the specified mouse button. Available mouse buttons are: M_LEFT, M_MIDDLE, M_RIGHT. Also, you could use the logical Id for the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through the :CONST export tag. zero is returned on failure, non-zero for success. ReleaseMouseButton BUTTON Releases the specified mouse button. Available mouse buttons are: M_LEFT, M_MIDDLE, M_RIGHT. Also, you could use the logical Id for the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through the :CONST export tag. zero is returned on failure, non-zero for success. SendKeys KEYS Sends keystrokes to the window that has the input focus. The keystrokes to send are those specified in KEYS parameter. Some characters have special meaning, they are: Modifier Keys: ^ CTRL % ALT + SHIFT # META Other Keys: ~ ENTER \n ENTER \t TAB ( and ) MODIFIER GROUPING { and } QUOTE / ESCAPE CHARACTERS Simply, one can send a text string like so: SendKeys('Hello, how are you today?'); Parenthesis allow a modifier to work on one or more characters. For example: SendKeys('%(f)q'); # Alt-f, then press q SendKeys('%(fa)^(m)'); # Alt-f, Alt-a, Ctrl-m SendKeys('+(abc)'); # Uppercase ABC using shift modifier SendKeys('^(+(l))'); # Ctrl-Shift-l SendKeys('+'); # Press shift Braces are used to quote special characters, for utilizing aliased key names, or for special functionality. Multiple characters can be specified in a brace by space delimiting the entries. Characters can be repeated using a number that is space delimited after the preceeding key. Quote Special Characters SendKeys('{{}'); # { SendKeys('{+}'); # + SendKeys('{#}'); # # You can also use QuoteStringForSendKeys to perform quoting. Aliased Key Names SendKeys('{BAC}'); # Backspace SendKeys('{F1 F2 F3}'); # F1, F2, F3 SendKeys('{TAB 3}'); # Press TAB 3 times SendKeys('{SPC 3 a b c}'); # Space 3 times, a, b, c Special Functionality # Pause execution for 500 milliseconds SendKeys('{PAUSE 500}'); Combinations SendKeys('abc+(abc){TAB PAUSE 500}'); # a, b, c, A, B, C, Tab, Pause 500 SendKeys('+({a b c})'); # A, B, C The following abbreviated key names are currently recognized within a brace set. If you don't see the desired key, you can still use the unabbreviated name for the key. If you are unsure of this name, utilize the xev (X event view) tool, press the key you want and look at the tools output for the name of that key. Names that are in the list below can be utilized regardless of case. Ones that aren't in this list are going to be case sensitive and also not abbreviated. For example, using 'xev' you will find that the name of the backspace key is BackSpace, so you could use {BackSpace} in place of {bac} if you really wanted to. Name Action ------------------- BAC BackSpace BS BackSpace BKS BackSpace BRE Break CAN Cancel CAP Caps_Lock DEL Delete DOW Down END End ENT Return ESC Escape F1 F1 ... ... F12 F12 HEL Help HOM Home INS Insert LAL Alt_L LMA Meta_L LCT Control_L LEF Left LSH Shift_L LSK Super_L MNU Menu NUM Num_Lock PGD Page_Down PGU Page_Up PRT Print RAL Alt_R RMA Meta_R RCT Control_R RIG Right RSH Shift_R RSK Super_R SCR Scroll_Lock SPA Space SPC Space TAB Tab UP Up zero is returned on failure, non-zero for success. For configurations (Xvfb) that don't support Alt_Left, Meta_Left is automatically used in its place. PressKey KEY Presses the specified key. One can utilize the abbreviated key names from the table listed above as outlined in the following example: # Alt-n PressKey('LAL'); # Left Alt PressKey('n'); ReleaseKey('n'); ReleaseKey('LAL'); # Uppercase a PressKey('LSH'); # Left Shift PressKey('a'); ReleaseKey('a'); ReleaseKey('LSH'); The ReleaseKey calls in the above example are there to set both key states back. zero is returned on failure, non-zero for success. ReleaseKey KEY Releases the specified key. Normally follows a PressKey call. One can utilize the abbreviated key names from the table listed above. ReleaseKey('n'); zero is returned on failure, non-zero for success. PressReleaseKey KEY Presses and releases the specified key. One can utilize the abbreviated key names from the table listed above. PressReleaseKey('n'); This function is affected by the key send delay. zero is returned on failure, non-zero for success. IsKeyPressed KEY Determines if the specified key is currently being pressed. You can specify such things as 'bac' or the unabbreviated form 'BackSpace' as covered in the SendKeys information. Brace forms such as '{bac}' are unsupported. A '{' is taken literally and letters are case sensitive. if (IsKeyPressed('esc')) { # Is Escape pressed? if (IsKeyPressed('a')) { # Is a pressed? if (IsKeyPressed('A')) { # Is A pressed? Returns non-zero for true, zero for false. IsMouseButtonPressed BUTTON Determines if the specified mouse button is currently being pressed. Available mouse buttons are: M_LEFT, M_MIDDLE, M_RIGHT. Also, you could use the logical Id for the button: M_BTN1, M_BTN2, M_BTN3, M_BTN4, M_BTN5. These are all available through the :CONST export tag. if (IsMouseButtonPressed(M_LEFT)) { # Is left button pressed? Returns non-zero for true, zero for false. IsWindow WINDOWID zero is returned if the specified window Id is not for something that can be recognized as a window. non-zero is returned if it looks like a window. IsWindowViewable WINDOWID zero is returned if the specified window Id is for a window that isn't viewable. non-zero is returned if the window is viewable. MoveWindow WINDOWID, X, Y Moves the window to the specified location. zero is returned on failure, non-zero for success. ResizeWindow WINDOWID, WIDTH, HEIGHT Resizes the window to the specified size. zero is returned on failure, non-zero for success. IconifyWindow WINDOWID Minimizes (Iconifies) the specified window. zero is returned on failure, non-zero for success. UnIconifyWindow WINDOWID Unminimizes (UnIconifies) the specified window. zero is returned on failure, non-zero for success. RaiseWindow WINDOWID Raises the specified window to the top of the stack, so that no other windows cover it. zero is returned on failure, non-zero for success. LowerWindow WINDOWID Lowers the specified window to the bottom of the stack, so other existing windows will cover it. zero is returned on failure, non-zero for success. GetInputFocus Returns the window that currently has the input focus. SetInputFocus WINDOWID Sets the specified window to be the one that has the input focus. zero is returned on failure, non-zero for success. GetWindowPos WINDOWID Returns an array containing the position information for the specified window. It also returns size information (including border width) and the number of the screen where the window resides. my ($x, $y, $width, $height, $borderWidth, $screen) = GetWindowPos(GetRootWindow()); GetParentWindow WINDOWID Returns the parent of the specified window. zero is returned if parent couldn't be determined (i.e., root window). GetScreenRes [SCREEN] Returns the screen resolution. If no screen is specified, it is taken from the value given when opening the X display. If the screen (number) is invalid, the returned list will be empty. my ($x, $y) = GetScreenRes(); GetScreenDepth [SCREEN] Returns the color depth for the screen. If no screen is specified, it is taken from the value given when opening the X display. If the screen (number) is invalid, -1 will be returned. Value is represented as bits, i.e. 16. my $depth = GetScreenDepth(); OTHER DOCUMENTATION Available under the docs sub-directory.
