It is recommended to create a dedicated virtual environment:

python -m venv .venv
source .venv/bin/activate

Ensure that the JAVA_HOME environment variable is set to the path to valid java JDK. Then ensure that the project is installed:

pip install -e ".[test,dev]"

Then run test. By default, pytest searches for tests in the */tests directory.

pytest

Note: in order to run, the tests of the Java-Python bridge require Python to start a JVM with classes of the module and its dependencies referenced in the classpath. Currently, the classpath is set manually in the src/test/python/tests/__init__.py file.

If classes are not found when trying to access a java class from Python, check that the requested class and its imported dependencies are present on the JVM's classpath.
