pytest-cov vs. UndercoverCI

This plugin produces comprehensive coverage reports that surpass the basic capabilities of using coverage run alone. It offers subprocess execution support, enabling users to fork or run tasks in a separate subprocess while still collecting coverage data effortlessly. Furthermore, it seamlessly integrates with xdist, allowing users to access all features of pytest-xdist without compromising coverage reporting. The plugin ensures compatibility with pytest, providing consistent access to all functionalities of the coverage package, whether through pytest-cov's command line options or the coverage configuration file. Occasionally, a stray .pth file may linger in the site packages post-execution. To ensure a fresh start for each test run, the data file is cleared before testing begins. If you need to merge coverage results from different test runs, you can utilize the --cov-append option to incorporate this information into previous results. At the end of testing, the data file is preserved, enabling users to make use of standard coverage tools for additional analysis of their findings. This extra functionality not only improves the overall user experience but also provides enhanced control over coverage data management throughout the testing lifecycle, ultimately leading to more efficient testing practices.

Elevate your Ruby testing and GitHub workflow with actionable insights on code coverage that empower your team to produce high-quality code efficiently while reducing the time dedicated to pull request evaluations. Instead of aiming for a flawless 100% test coverage, prioritize the reduction of defects in your pull requests by pinpointing untested code modifications before deployment. Following a simple configuration where your CI server executes tests and communicates coverage results to UndercoverCI, you can guarantee that every pull request undergoes thorough scrutiny; our tool examines the adjustments in your code and evaluates local test coverage for all altered classes, methods, and blocks, as relying solely on an overall coverage percentage is inadequate. This solution reveals untested methods and blocks, points out unused code paths, and assists in optimizing your test suite. You can seamlessly incorporate UndercoverCI’s hosted GitHub App or explore the variety of available Ruby gems. With a comprehensive integration for code reviews via GitHub, the setup process is swift and customized to meet your organization’s specific needs. Furthermore, the UndercoverCI initiative, along with its Ruby gems, is entirely open-source and can be freely employed in your local environment as well as throughout your CI/CD pipelines, making it an adaptable option for any development team. By embracing UndercoverCI, you enhance your code quality while also cultivating a culture of ongoing improvement within your team, ultimately leading to a more efficient development process. This initiative not only promotes better coding practices but also encourages collaboration and knowledge sharing among team members.
