[py-dev] Creating test skeleton automatically from modules
by Edvard Majakari March 15, 2005

March 15, 2005

Hi, I wrote a simple program which uses Python's compiler module to parse given set of modules and writes a py.test unit test skeleton for each module. Currently it is not too clever, mostly because I don't have very clear ideas how unit testing should be done. However, it does create code for automatically generating test methods :) Say, if you have module bar and therein method named foo, pytestgen will automatically create TestBar: ... def test_foo(self): known_values(,) for arg1, arg2, expected in known_values: yield self.foo, arg1, arg2, expected def foo(self, arg1, arg2, expectd): assert bar.foo(arg1, arg2) == expected I intend to develop the program further, hopefully integrate it to Eclipse pydev plugin :) If you're interested in trying it out, see http://majakari.net/dl/pytestgen-0.11.tar.bz2 It's not too advanced (yet), but I already use it myself for my own purposes. -- # Edvard Majakari Software Engineer # PGP PUBLIC KEY available Soli Deo Gloria! $_ = '456476617264204d616a616b6172692c20612043687269737469616e20'; print join('',map{chr hex}(split/(\w{2})/)),uc substr(crypt(60281449,'es'),2,4),"\n";

[py-dev] py.test patches and problems
by Valentino Volonghi aka Dialtone March 6, 2005

March 6, 2005

I think there is far too magic in py.test :). Since I need a markdown parser I've started a new project. Unfortunately the Markdown test suite is completely useless (whoever wrote it must have some problems with blank lines in html output). Hence I wanted to build my own test suite using py.test First problem: I'm under MacOSX and I'm using python built with the framework. This means _findpy.py is not ready to locate my py dir and fails (even if import py finishes without problems). I modified _findpy.py in this way: Index: py/bin/_findpy.py =================================================================== --- py/bin/_findpy.py (revision 9671) +++ py/bin/_findpy.py (working copy) @@ -27,6 +27,9 @@ if not searchpy(abspath(os.curdir)): if not searchpy(opd(abspath(sys.argv[0]))): if not searchpy(opd(__file__)): - raise SystemExit, "Could not find 'py' package!" + for path in sys.path: + if searchpy(path): + break + else: raise SystemExit, "Could not find 'py' package!" import py And now it works. Pythondir under MacOSX with framework is: /Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages while python executable is under: /Library/Frameworks/Python.framework/Versions/2.4/bin/python But then there is another problem with other software that uses __import__() function. I'm working with Nevow and it uses a particular function: namedAny which loads a module from PYTHONPATH using the complete path to the module. This is one of the many error outputs that I have while running 'py.test'. def namedAny(name): """Get a fully named package, module, module-global object, or attribute. """ names = name.split('.') topLevelPackage = None moduleNames = names[:] while not topLevelPackage: try: trialname = '.'.join(moduleNames) E topLevelPackage = __import__(trialname) ~ ImportError: __import__('nevow.flat.flatstan.TagSerializer') << No module named TagSerializer Is there any way to fix this last behaviour? I fear that import hooks are too magic, for a py.test newbie like me, to dig in. -- Valentino Volonghi aka Dialtone Now Running MacOSX 10.3.8 Blog: http://vvolonghi.blogspot.com http://weever.berlios.de

[py-dev] using Python profiler with py.test
by Matthew Scott March 4, 2005

March 4, 2005

I'm having problems using the Python profiler with py.test If I write a simple one-liner as 'hello.py': import py; print py.path.local() Then run "python2.4 -m profile hello.py", I get a report from the profiler. However, if I run "python2.4 -m profile bin/py.test" from within the py directory, I get the output below. Any ideas or tips on using the Python profiler with py.test? inserting into sys.path: /home/gldnspud/s/py-dist ============================= test process starts ============================= testing-mode: inprocess executable : /usr/bin/python2.4 (2.4.1-alpha-0) using py lib: /home/gldnspud/s/py-dist/py <rev unknown> Traceback (most recent call last): File "/usr/lib/python2.4/profile.py", line 611, in ? run('execfile(%r)' % (sys.argv[0],), options.outfile, options.sort) File "/usr/lib/python2.4/profile.py", line 72, in run prof = prof.run(statement) File "/usr/lib/python2.4/profile.py", line 448, in run return self.runctx(cmd, dict, dict) File "/usr/lib/python2.4/profile.py", line 454, in runctx exec cmd in globals, locals File "<string>", line 1, in ?
