Python unit test when structure changes

Title: Python Unit Testing for Evolving Code Structures
Introduction:
Unit testing is a crucial aspect of software development that helps ensure your code works correctly as it evolves over time. In this tutorial, we will explore how to write unit tests in Python, even when the structure of your code changes. We'll focus on strategies and best practices for adapting your tests to code modifications, using real-world examples.
Prerequisites:
Table of Contents:
Setting up a Unit Testing Framework
Creating Test Cases
Adapting Tests to Code Structure Changes
Best Practices for Flexible Testing
Continuous Integration (CI) with Testing

Setting up a Unit Testing Framework:
Example: If some_function was renamed to new_function, adapt the test case as follows:
Best Practices for Flexible Testing:
To create maintainable tests in the face of code structure changes, follow these best practices:
Continuous Integration (CI) with Testing:
Integrate your tests into your CI/CD pipeline to ensure they run automatically when changes are pushed to your code repository. Services like Jenkins, Travis CI, or GitHub Actions can automate this process.
Conclusion:
Unit testing in Python is a powerful tool for ensuring your code functions correctly as it evolves. By following best practices and adapting your tests to changing code structures, you can maintain a reliable test suite that helps catch issues early in development. Remember that writing tests is an ongoing process that parallels code development, and investing time in testing can save you from future headaches.
