Since testcontainers-python :material-tag: v4.7.0

The Testcontainers module for testing Python module imports and package management. This module provides a containerized environment for testing various aspects of Python module imports, including:

• Basic module and package imports
• Module reloading
• Version-specific imports
• Dependencies and environment variables
• Advanced features like custom loaders and namespace packages

Please run the following command to add the Test Module Import module to your python dependencies:

pip install testcontainers[test_module_import]

The module provides several examples demonstrating different use cases:

This example demonstrates the fundamental capabilities of the TestModuleImportContainer:

• Importing a basic Python module and accessing its attributes
• Importing and using submodules
• Importing and working with packages
• Proper cleanup of imported modules

Basic module imports

This example shows how to work with module reloading functionality:

• Importing a module and accessing its initial state
• Reloading the module to pick up changes
• Handling reloading errors gracefully
• Managing module state during reloads

Module reloading

This example demonstrates handling version-specific module imports:

• Importing specific versions of modules
• Managing version compatibility
• Accessing and verifying version information
• Working with version-specific features

Version-specific imports

This example shows how to handle module dependencies and environment requirements:

• Importing modules with external dependencies
• Managing required dependency versions
• Setting up and accessing environment variables
• Handling environment-specific configurations

Dependencies and environment variables

This example demonstrates advanced module import capabilities:

• Using custom module loaders for specialized import scenarios
• Working with namespace packages
• Managing entry points
• Handling complex module configurations
