A tool that predicts Software defects from GIT repositories.
A tool that analyzes GIT Repositories and estimates the defect probability of Software components to help developers focusing their resources to fix bugs where they really are. We are currently supporting method granularity for Java.
Schwa is under heavy development as a Master Thesis and is only available as pre-release on the Python Package Index.
Install Python3 and pip first and then:
pip3.4 install schwa --pre
python3.4 setup.py install
usage: schwa [-h] [--commits COMMITS] repository Predicts defects from GIT repositories. positional arguments: repository repository full path on local file system optional arguments: -h, --help show this help message and exit --commits COMMITS maximum number of commits, since the last one, to be analyzed
from schwa import Schwa s = Schwa(repository_path) analytics = s.analyze()
You can configure Schwa parameters using a YAML file. Just place a .schwa.yml file in the root of the repository and use this example:
commits: 20 # maximum commits features_weights: # sum must be 1 revisions: 0.3 fixes: 0.5 authors: 0.2
Project documentation is available in the Wiki. Please read it to get familiar with the project.
