ANN: Oktest-0.2.2 - a new-style testing library


Makoto Kuwata

I released Oktest 0.2.2.


Oktest is a new-style testing library for Python.

from oktest import ok
ok (x) > 0 # same as assert_(x > 0)
ok (s) == 'foo' # same as assertEqual(s, 'foo')
ok (s) != 'foo' # same as assertNotEqual(s, 'foo')
ok (f).raises(ValueError) # same as assertRaises(ValueError, f)
ok (u'foo').is_a(unicode) # same as assert_(isinstance(u'foo', unicode))
not_ok (u'foo').is_a(int) # same as assert_(not isinstance(u'foo', int))
ok ('A.txt').is_file() # same as assert_(os.path.isfile('A.txt'))
not_ok ('A.txt').is_dir() # same as assert_(not os.path.isdir('A.txt'))

You can use ok() instead of 'assertXxx()' in unittest.

Oktest requires Python 2.3 or later. Oktest is ready for Python 3.

NOTICE!! Oktest is a young project and specification may change in the future.

See for details.


* Enhanced to set 'f.exception' after 'ok (f).raises(Exception)'
to get raised exception object. For example::

def f():
ok (f).raises(ValueError)
ok (f.exception.message) == "invalid literal for int() with base
10: 'foobar'"

* Changed to flush output after '.'/'f'/'E' printed

* Change to get exception message by 'str(ex)' instead of 'ex.message'

Have fun!
