FlaPy

FlaPy is a small tool that allows software developers to automatically check tests for flakiness.

It is the result of research carried out at the Chair of Software Engineering II at the University of Passau, Germany.

Prerequisites

Before you begin, ensure you have met the following requirements:

  • Python in at least version 3.7.
  • You have installed the latest version of poetry.
    • pip install poetry
  • You have a Linux machine with a recent kernel and activated cgroups. We refer you to the installation documentation of BenchExec, a framework for reliable benchmarking and resource measurement, which we use for running all test cases in isolation.

Installing from source

git clone https://github.com/se2p/FlaPy.git
cd FlaPy
poetry install
poetry build

Using FlaPy

             # Drop first line, which contains the header
./run_csv.sh <(tail -n+2 sample_input.csv)

Results can then be found under ./flapy-results/

To parse the results, use

poetry run results_parser ResultsDir --dir=flapy-results get_passed_failed to_csv --index=False > passed_failed_sample.csv

poetry run results_parser PassedFailed --file_ passed_failed_sample.csv to_test_overview to_csv --index=False > test_overview_sample.csv

An overview of the results can now be found in passed_failed_sample.csv and test_overview_sample.csv

Building the project

The project can be built by using the poetry tool:

poetry build

This command will build two files in the dist folder: A tar.gz archive and a whl Python wheel file.
