Algorand Python Testing is a companion package to Algorand Python that enables efficient unit testing of Algorand Python smart contracts in an offline environment. It emulates key AVM behaviors without requiring a network connection, offering fast and reliable testing capabilities with a familiar Pythonic interface.

Quick start

The easiest way to use Algorand Python Testing is to instantiate a template with AlgoKit via algokit init -t python. This will give you a full development environment with testing capabilities built-in.

Alternatively, if you want to start from scratch:

1. Ensure you have Python 3.12+

2. Install AlgoKit CLI

3. Install Algorand Python Testing into your project:

   pip install algorand-testing-python

4. Create a test file (e.g., test_contract.py):

   from algopy_testing import algopy_testing_context
   from your_contract import YourContract
   
   def test_your_contract():
       with algopy_testing_context() as context:
           # Arrange
           contract = YourContract()
           expected_result = ... # Your expected result here
   
           # Act
           result = contract.your_method(context.any.uint64())  # Your test code here
   
           # Assert
           assert result == expected_result

5. Run your tests using your preferred Python testing framework (e.g., pytest, unittest)
