Fwd: PyUseCase 3.5.1: GUI test tool written in Python
by Geoff Bache May 5, 2011

May 5, 2011

Hi all, There's a bugfix release of PyUseCase out. It fixes general issues as well as some specific to SWT/Eclipse RCP and some specific to PyGTK. There are also some minor enhancements added to the SWT/Eclipse RCP support. Regards, Geoff Bache A bit more detail: PyUseCase is an unconventional GUI testing tool for PyGTK, Tkinter, wxPython and SWT along with a framework for testing Python GUIs in general. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates this language into actions on the current GUI widgets. The point is to reduce coupling, allow very expressive tests, and ensure that GUI changes mean changing the UI map file but not all the tests. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it. The point is then to use that as a baseline for text-based testing, using TextTest. It also includes support for instrumenting code so that "waits" can be recorded, making it far easier for a tester to record correctly synchronized tests without having to explicitly plan for this.

[ann] pyjamas 0.8alpha1 release
by Luke Kenneth Casson Leighton May 4, 2011

May 4, 2011

after a long delay the pyjamas project - http://pyjs.org - has begun the 0.8 series of releases, beginning with alpha1: https://sourceforge.net/projects/pyjamas/files/pyjamas/0.8/ pyjamas is a suite of projects, including a python-to-javascript compiler with two modes of operation (roughly classified as "python strict" and "Optimised"); a GUI Framework almost identical to that of the GWT Project (1.5 to 1.7); and a "Desktop" version which is similar in concept to Adobe Air, allowing python applications to be run - unmodified - as stand-alone Desktop Applications. pyjamas can therefore be considered to be a Desktop GUI framework - a peer of GTK2 and QT4 - with the startling capability that applications can also be compiled to javascript and run in any modern web browser with absolutely no special plugins required, or it can be considered to be an AJAX Web Framework with the massive advantage that applications are written in python (not javascript) with a "Desktop" mode as well. both descriptions are accurate, making pyjamas the world's only free software python-based platform-independent, browser-independent, GUI-toolkit-independent and OS-independent "Holy Grail" GUI development environment [so there. nyer, nyer to the corporate big boys with access to $m who *still* haven't managed that one] also included are ports of GChart and GWTCanvas, each of which run under all web browsers and all desktop engines (with the exception at present of the python-webkit desktop engines, which presently do not support SVG Canvas). all pyjamas UI libraries are designed to be browser-independent as well as platform independent. the usual "browser foibles", tricks and gotchas are catered for with a transparent "Platform Override" mechanism which ensures that the published API of each UI Library is identical across all platforms (including the Desktop Engines). [no more "If Platform == IE or Platform == Opera...."] due to the sheer number of modern browsers as well as the number of pyjamas-desktop engines required to be supported, the 0.8 series will be ready declared "stable" when sufficient community-led testing has been done. bugreports are in for Opera 11, IE8 and Google Chrome: http://code.google.com/p/pyjamas/issues/detail?id=600 http://code.google.com/p/pyjamas/issues/detail?id=601 http://code.google.com/p/pyjamas/issues/detail?id=597 still requiring testing and confirmation is Opera 9 and 10; Firefox 2, 3, 3.1, 3.5, 3.6 and 4.0; IE6, 7 and 9; Safari 3 and 4, as well as mobile phone browsers Android, Symbian Series 60, iphone, ipad and blackberry OS 4. also requiring testing and confirmation is the Desktop Engines, of which there are now four variants: XulRunner (Firefox Engine), pywebkitgtk, MSHTML and the new addition pywebkitdfb (DirectFB). each browser and each engine requires each of the 70 examples to be run, and in the case of the pyjamas compiler (pyjs), compilation is required with both -O and --strict (with the exception of the LibTest example). the pywebkitdfb engine is a new addition, and merits a particular mention. some time last year, both GTK2 and QT4 independently announced that they were dropping support for DirectFB from future versions, and Enlightenment had not tested the DirectFB port for some considerable time. Webkit-GTK with the older GTK-DirectFB libraries simply would not compile. in the embedded space, where it can take 30 seconds to fire up Webkit-GTK on a 400mhz ARM9 and even longer to start up WebkitQT4, this was something of a disaster. To fix this, a new port of Webkit was created which uses DirectFB directly, using a tiny 50k Widget Toolkit called "Lite". This development coincided with the re-engineering of pywebkitgtk and the creation of the pythonwebkit project, http://www.gnu.org/software/pythonwebkit: pywebkitdfb was therefore also created at the same time. Cutting a long story short, pywebkitdfb now exists and has a startup time on 400mhz ARM9 processors of under 1.5 seconds. The startup time of both WebkitDFB and pywebkitdfb on Dual-Core 2ghz Intel systems is so quick that it's difficult to determine: an estimate is under 0.1 seconds (100ms). WebkitGTK. WebkitEFL and WebkitQT4 have approximately 20 times or longer startup times. So although WebkitDFB is still significantly experimental, it is definitely worthwhile considering, especially for Embedded Systems, but even for use on X-Windows, and even just as a plain (but modern) web browser for those people sick to the back teeth of long startup times on their web browser [and it has python bindings, too. yaay!] summary: developing applications in pyjamas means the application can be made to run just about anywhere, and it's an entirely python-based and a free software framework. it's a community-driven project, so requires *your* input to get it to a proven stable state. http://pyjs.org

This distribution provides bots built on this framework for console, IRC, XMPP and Convore for the shell and WWW and XMPP for the Google Application engine. JSONBOT is all of the following: * a shell console bot * a shell IRC bot * a shell XMPP bot * a shell Convore bot * a Web bot running on Google Application Engine * a XMPP bot running on Google Application Engine * a Google Wave bot running op Google Application Engine * the XMPP bots are used to communicate between bots * plugin infrastructure to write your own functionality * event driven framework by the use of callbacks Install ------- You dont need to run the bot on GAE when you just want to use the shell bots of JSONBOT. JSONBOT can best be run from the bot dir, the bot is self contained and has all the dependancies that are needed: * "hg clone http://jsonbot.googlecode.com/hg mybot" or download and untar the tarball. * cd into the bot dir and run "./bin/jsb" .. if the bot is working correctly you will get the console version of JSONBOT * same can be done for "./bin/jsb-xmpp", "./bin/jsb-convore" etc. .. check the bin dir for programs you can start * try the --help option to a program to see what command line options are available. * you DONT need root for this Ofcourse you can always run "python setup.py install" or "easy_install -U jsb" when you do want to install the bot globaly. Debian packages are on their way, but might still take time as the ftpmeisters need to approve ;] Thats it ! hope you enjoy this version of JSONBOT ;] Bart
