Scalable Approaches for Test Suite Reduction

This repository is a companion page for an ICSE'19 submission. It contains all the material required for replicating our experiments, including: the implementation of the algorithms, the input data, and supplementary tools. Some additional results, not included in the paper for the sake of space, are also provided.

Pseudocode

The pseudocode of all algorithms are available here (some of them were not reported in the paper for lack of space).

Experiment Results and Data

The results of our experiments as well as the data we used for our statistical analysis are available here.

Experiment Replication

In order to replicate the experiment follow these steps:

Getting started

  1. Clone the repository

    • git clone https://github.com/ICSE19-FAST-R/FAST-R

  2. Install the additional python packages required:

    • pip3 install -r requirements.txt

Budget Scenario

  1. Execute the experimentBudget.py script

    • python3 py/experimentBudget.py <coverageType> <program> <version>

    The possible values for <coverageType> are: function, line, branch.

    The possible values for <entity> <version> are: flex v3, grep v3, gzip v1, make v1, sed v6, chart v0, closure v0, lang v0, math v0, time v0.

  2. The results are printed on screen and stored inside folder outputBudget-<coverageType>/

Adequate Scenario

  1. Execute the experimentAdequate.py script

    • python3 py/experimentAdequate.py <coverageType> <program> <version>

    The possible values for <coverageType> are: function, line, branch.

    The possible values for <entity> <version> are: flex v3, grep v3, gzip v1, make v1, sed v6, chart v0, closure v0, lang v0, math v0, time v0.

  2. The results are printed on screen and stored inside folder outputAdequate-<coverageType>/

Large Scale Scenario

  1. Create scalability dataset

    • cat input/scalability/scalability-bbox.txt.gz_* > input/scalability/scalability-bbox.txt.gz && gunzip input/scalability/scalability-bbox.txt.gz

  2. Execute the experimentLargeScale.py script

    • python3 py/experimentLargeScale.py <algorithm>

    The possible values for <algorithm> are: FAST++, FAST-CS, FAST-pw, FAST-all.

  3. The results are printed on screen and stored inside folder outputLargeScale/

Directory Structure

This is the root directory of the repository. The directory is structured as follows:

FAST-R
 .
 |
 |--- input/         Input of the algorithms, i.e. fault matrix, coverage information, and BB representation of subjects.
 |
 |--- pseudocode/    Pseudocode of the algorithms.
 |
 |--- py/            Implementation of the algorithms and scripts to execute the experiments.
