ostdetector 1.0.3

A tool for extracting of OS-Specific Tests

OSTDetector

An automated tool for extracting OS-specific Tests from Git repositories written in Python. The ostdetector (Operating System-Specific Tests Detector) is primarily designed to be used as a command-line tool. With ostdetector, you can easily extract information about the OS-specific Tests from the Git repository (only python files are analyzed). The set of OS-specific Tests are saved in a given CSV file.

Install

The easiest way to install ostdetector is to install from Pypi

pip install -i https://test.pypi.org/simple/ ostdetector==1.0.5

Alternatively, you can install from test environment

pip install --index-url https://test.pypi.org/simple/ --no-deps ostdetector

You may wish to use this tool in a virtual environment. You can use the following commands.

virtualenv ostdetector_venv
source ostdetector_venv/bin/activate
pip install ostdetector

Quick examples

As an example, the following command extracts every OS-Specific Testes from the repository ricardojob/ostdetector. It also saves various information (line, module, filename ...) in directory dir_output. This information will be available in the output file.

ostdetector ricardojob/ostdetector -o dir_output

Note that the tool also can fetch it. For example, the GitHub repository https://github.com/ricardojob/ostdetector will be fetched, saved under the dir_output/ricardojob directory. Note that, by default all projects are cloned to the data directory.

Usage

After installation, the ostdetector command-line tool should be available in your shell. Otherwise, please replace ostdetector by python -m ostdetector. The explanations in the following stays valid in both cases.

You can use ostdetector with the following arguments:

Usage: ostdetector [OPTIONS] REPOSITORY

  Extract the usage of OS-Specific Tests from a single Git repository
  `REPOSITORY`. The Git repository can be remote. It will be pulled locally in
  the folder `data`. Every extracted OS-Specific Tests will be written in the
  dir given to `-o`, or in the `data' if not specified.

  Example of usage: python main.py ricardojob/OSTDetector -o data_experiment

Options:
  -o, --output DIRECTORY  The output dir where the usage of OS-Specific Tests
                          related to the repository will be stored. By
                          default, the information will written to `data' dir.
  -h, --help              Show this message and exit.

The *compare.csv' file given to directory -o` will contain the following columns:

• project_name: the name of the repository
• project_hash: the commit SHA of the commit where the OS-specific tests file was extracted
• line: the line where the OS-specific tests usage occurs
• module: the module that packages the OS-specific tests (e.g., sys)
• package: the API (e.g., platform)
• platform: the information about OS (e.g, win32)
• file: the file name
• function: the function name
• method_type: the method type (method_test or support)
• url: the URL that represents the API usage on Github
