GlueTest: Testing Code Translation via Language Interoperability

This is an artifact for the paper, "GlueTest: Testing Code Translation via Language Interoperability" presented at ICSME 2024 NIER. It contains the following directories:

1. commons-cli and commons-csv: original Commons CLI and CSV source code and tests
2. commons-cli-python and commons-csv-python: translated code and tests in python
3. commons-cli-graal and commons-csv-graal: python source code, java tests, and (Java) glue code for GraalVM
4. graal-glue-generator: contains the source code for the glue code generator
5. scripts: contains scripts run local coverage, coverage through CI, collecting clients, and generating glue code.

Setting up GraalVM and GraalPython

To run the GraalVM integration, we need to install the GraalVM SDK and the python component. To install GraalVM, we use the SDKMAN! tool. To install SDKMAN!, run the following command from the SDKMAN! website:

curl -s "https://get.sdkman.io" | bash

After installing SDKMAN!, we can install GraalVM (Java 17) using the following command from their website:

sdk install java 17.0.7-graal

After installing GraalVM, we need to install the python component. To do so, we run:

gu install python

Running Tests

All commands for running tests can be found in the run.sh file in the root directory, and can be run with:

bash run.sh

To see a description for each command, please see the following sections.

Running the original Java tests

# Commons CLI
mvn -f commons-cli/pom.xml test -Drat.skip
# Commons CSV
mvn -f commons-csv/pom.xml test -Drat.skip

NOTE: This step requires maven to be installed. If maven is not installed, see their web page for installation instructions.

Running the translated Python Tests

In order to run the python tests, pytest is needed and can be installed with the following command:

python -m pip install pytest

Then, the python tests can be run with:

# Commons CLI
pytest commons-cli-python
# Commons CSV
pytest commons-csv-python

NOTE: We use CPython 3.11.4 for running our translation tests. Please ensure a compatible of Python is installed before running tests.

Running glue code tests with GraalVM

# Commons CLI
mvn -f commons-cli-graal/pom.xml test -Drat.skip
# Commons CSV
mvn -f commons-csv-graal/pom.xml test -Drat.skip

Measure coverage

Coverage for our glue code is measured using a python script, cover.py in the scripts/ directory. To run coverage, we run the local version of our script:

python scripts/coverage/cover_local.py 

Running the Glue Automation

To automatically generate glue for all classes in Commons CLI and Commons CSV, run the following from the root directory:

python scripts/generate_glue.py

The glue code automation will generate the files under the generated/commons-cli and generated/commons-csv directories, which can be used as drop-in replacements for the glue code in commons-cli-graal and commons-csv-graal respectively.

Collecting Clients

We provide the scripts for scraping clients under scripts/clients/selenium.py. The scripts/clients/bash_script_version.sh script can further be used to extract the versions of the libraries used by the clients.
