==================================== AllPairs test combinations generator

AllPairs is an open source test combinations generator written in Python, developed and maintained by MetaCommunications Engineering. The generator allows one to create a set of tests using "pairwise combinations" method, reducing a number of combinations of variables into a lesser set that covers most situations.

For more info on pairwise testing see http://www.pairwise.org.

The easiest way to get started is to check out usage examples in the "examples" directory and online at https://apps.sourceforge.net/trac/allpairs/browser/examples/.

Features

• Produces good enough dataset.

• Pythonic, iterator-style enumeration interface.

• Allows to filter out "invalid" combinations during search for the next combination.

• Allows to exclude "previously tested" pairs/combinations.

• Goes beyond pairs! If/when required can generate n-wise combinations.

Installation

To install AllPairs to your Python's site-packages directory, run this command from the command prompt:

python setup.py install

Alternatively, you can just copy the entire "pairwise" directory somewhere into your Python path.

Ps.: AllPairs need to run with Python 3

If you have this problem (windows):

• ModuleNotFoundError: No module named... *

You must run this command

setx PYTHONPATH ";\DLLs;\lib;\lib\plat-win;\lib\site-packages"

Ex.: setx PYTHONPATH "C:\Programas\python\3.7.4;C:\Programas\python\3.7.4\DLLs;C:\Programas\python\3.7.4\lib;C:\Programas\python\3.7.4\lib\plat-win;C:\Programas\python\3.7.4\lib\site-packages"

Run

python examples/example1.1.py

Known issues

• Not optimal - there are tools that can create smaller set covering all the pairs. However, they are missing some other important features and/or do not integrate well with Python.

• Lousy written filtering function may lead to full permutation of parameters.

• Version 2.0 has become slower (a side-effect of introducing ability to produce n-wise combinations).
