== Coveralls == [[File:Coveralls.png|thumb|right|Coveralls Logo]] Coveralls is a code coverage tool that is commonly used in Elixir development. It helps developers analyze the quality and depth of their test suites by providing detailed reports on which parts of the code are covered by tests. This allows developers to identify areas of their codebase that may require additional testing. == Features == Coveralls offers a range of features that make it a popular choice for Elixir developers: === Code Coverage Reports === Coveralls generates detailed code coverage reports that help developers get a clear understanding of the test coverage for their Elixir project. These reports provide insights into which lines of code are executed by tests and which ones are not. === Integration with Continuous Integration Services === Coveralls seamlessly integrates with popular continuous integration services like Travis CI and GitHub Actions. This allows developers to automatically generate coverage reports and track the code coverage trend of their project over time. === Multiple Coverage Metrics === Coveralls supports various coverage metrics, including line coverage, function coverage, and branch coverage. This enables developers to measure not only the percentage of lines covered but also the percentage of functions and branches covered by tests. === Pull Request Integration === Coveralls can be easily integrated into the pull request workflow of a project. It provides developers with valuable feedback on the code coverage impact of their changes, making it easier to maintain test quality and catch potential regressions. === Badges === Coveralls generates badges that can be embedded in a project's README file or documentation. These badges visually represent the current code coverage of the project, allowing developers to showcase their test coverage achievements. == Usage == To use Coveralls in an Elixir project, follow these steps: 1. Add the `excoveralls` package as a dependency in your `mix.exs` file. 2. Configure the necessary settings for Coveralls, such as the coverage output format and the location of the coverage report. 3. Run the tests of your Elixir project using the `mix test` command. 4. After the tests have finished, generate the coverage report using the `mix coveralls.html` command. 5. Upload the generated coverage report to the Coveralls service using their API or a supported CI service integration. 6. Access the Coveralls website to view the detailed code coverage report for your Elixir project. Make sure to consult the [https://example.com/example-link example documentation] for more information on how to set up and use Coveralls in your Elixir project. == See Also == * [[Continuous Integration]] - Learn more about integrating Coveralls with popular continuous integration services. * [[Code Coverage]] - Explore other code coverage tools and techniques used in Elixir development. * [[Testing in Elixir]] - Discover best practices for testing Elixir applications. == References == <references /> [[Category:Elixir Tools]]
