The 'py' lib provides helper classes for capturing IO during
|
|
execution of a program.

|
IO Capturing examples
|
|
===============================================
|
|
|
|
``py.io.StdCapture``
|
|
---------------------------
|
|
|
|
Basic Example::
|
|
|
|
>>> import py
|
|
>>> capture = py.io.StdCapture()
|
|
>>> print "hello"
|
|
>>> out,err = capture.reset()
|
|
>>> out.strip() == "hello"
|
|
True
|
|
|
|
For calling functions you may use a shortcut::
|
|
|
|
>>> import py
|
|
>>> def f(): print "hello"
|
|
>>> res, out, err = py.io.StdCapture.call(f)
|
|
>>> out.strip() == "hello"
|
|
True
|
|
|
|
``py.io.StdCaptureFD``
|
|
---------------------------
|
|
|
|
If you also want to capture writes to the stdout/stderr
|
|
filedescriptors you may invoke::
|
|
|
|
>>> import py, sys
|
|
>>> capture = py.io.StdCaptureFD(out=False, in_=False)
|
|
>>> sys.stderr.write("world")
|
|
>>> out,err = capture.reset()
|
|
>>> err
|
|
'world'
|
