Improve Testability and Increase Code Coverage for Pace

[simonsan]

Overview

As Pace continues to grow and evolve, ensuring high-quality code becomes increasingly critical. This issue aims to address the current gaps in test coverage and testability of the Pace project and its libraries. By focusing on enhancing our testing infrastructure and practices, we can significantly reduce bugs, improve stability, and ensure that new features meet our standards for quality and reliability.

Objectives

• Assess Current Testing Framework: Evaluate the existing testing setup and identify areas for improvement.
• Increase Test Coverage: Identify critical areas of the codebase that are currently under-tested or not tested at all.
• Improve Testability of the Code: Refactor code where necessary to make it more amenable to unit and integration testing.
• Integrate Additional Testing Tools: Explore and integrate tools for coverage analysis, fuzz testing, and other advanced testing methodologies.
• Establish Testing Best Practices: Develop guidelines for writing effective tests and ensuring high-quality code.

Action Items

1. Codebase Audit for Test Coverage

   • Conduct a thorough audit of the current test suite to identify coverage gaps.
   • Create a list of components with insufficient tests.

2. Refactor for Testability

   • Identify and refactor tightly coupled components that hinder testability.

3. Expand Test Suite

   • Write additional unit tests to cover critical logic and functionality.

4. Tooling Integration

   • Set up a code coverage tool (we use cargo-tarpaulin)
   • Evaluate and integrate additional testing tools as needed.

5. Documentation and Guidelines

   • Document testing best practices and guidelines for contributors.
   • Include examples of effective tests and common patterns to avoid.

6. Continuous Improvement

   • Establish a process for regularly reviewing and improving test coverage.
   • Encourage contributions focused on testing via GitHub issues and pull requests.

Request for Contributions

We welcome contributions from the community to help achieve these objectives. Whether it's writing tests, refactoring for better testability, or improving our testing infrastructure, every contribution counts. If you're interested in helping, please comment on this issue with the areas you'd like to work on, or propose new ideas for enhancing our testing practices.

Conclusion

Improving testability and increasing code coverage are essential steps toward maintaining the Pace project's quality and reliability. With a solid testing foundation, we can confidently continue to develop and expand Pace, knowing that we have the practices and infrastructure in place to ensure its stability and performance.
