Run Unit Tests

Setup the Python environment and run unit tests for GenLayer Studio.

Prerequisites

• Python 3.12 installed
• virtualenv installed (pip install virtualenv)

Setup Virtual Environment (first time or reset)

Copy# Remove existing venv if present
rm -rf .venv

# Create new venv with Python 3.12
virtualenv -p python3.12 .venv

# Activate
source .venv/bin/activate

# Upgrade pip
pip install --upgrade pip

# Install all dependencies
pip install -r requirements.txt
pip install -r requirements.test.txt
pip install -r backend/requirements.txt

# Set Python path
export PYTHONPATH="$(pwd)"

Run Tests

Copy# Activate venv (if not already)
source .venv/bin/activate
export PYTHONPATH="$(pwd)"

# Run all unit tests
gltest --contracts-dir . tests/unit

# Run specific test file
gltest --contracts-dir . tests/unit/test_specific.py

# Run with verbose output
gltest --contracts-dir . tests/unit -v

# Run specific test function
gltest --contracts-dir . tests/unit/test_file.py::test_function_name

Quick One-Liner (after initial setup)

Copysource .venv/bin/activate && export PYTHONPATH="$(pwd)" && gltest --contracts-dir . tests/unit

Troubleshooting

Python 3.12 Not Found

Copy# Check available Python versions
which python3.12

# On macOS with Homebrew
brew install python@3.12

gltest Command Not Found

Copy# Make sure venv is activated
source .venv/bin/activate

# Reinstall test dependencies
pip install -r requirements.test.txt

Import Errors

Copy# Ensure PYTHONPATH is set
export PYTHONPATH="$(pwd)"

# Verify from project root
pwd  # Should be genlayer-studio
