Coco® is an adaptable tool created to gauge code coverage across a variety of programming languages. By employing automatic instrumentation of source code, it evaluates the coverage of statements, branches, and conditions throughout the testing process. When the instrumented application undergoes testing, it produces data that can later be analyzed in-depth. This analysis allows developers to understand how much of the source code has been tested, recognize areas lacking coverage, decide which additional tests are required, and monitor changes in coverage over time. Furthermore, it assists in identifying redundant tests and locating untested or outdated code sections. By assessing the impact of patches on both the codebase and the overall coverage, Coco offers a detailed perspective on testing effectiveness. It accommodates various coverage metrics, such as statement coverage, branch coverage, and Modified Condition/Decision Coverage (MC/DC), which makes it suitable for a range of environments including Linux, Windows, and real-time operating systems. Additionally, the tool is compatible with several compilers, including GCC, Visual Studio, and embedded compilers, providing flexibility for developers. Users can select from multiple report formats like text, HTML, XML, JUnit, and Cobertura to meet their specific requirements. Moreover, Coco easily integrates with numerous build, testing, and continuous integration frameworks, such as JUnit, Jenkins, and SonarQube, thereby enhancing its functionality within a developer's workflow. This extensive array of features positions Coco as an invaluable resource for teams dedicated to delivering high-quality software through robust testing methodologies, ensuring that every aspect of the code is thoroughly examined. Ultimately, Coco empowers developers to optimize their testing processes to achieve the best outcomes.

JaCoCo is a free library for Java code coverage, crafted by the EclEmma team, and has seen continuous improvement over the years based on insights gained from other libraries. The master branch of JaCoCo undergoes automatic building and publishing, which guarantees that each build complies with test-driven development principles, ensuring full functionality. Users can refer to the change history for the latest features and bug fixes. In addition, metrics related to the current JaCoCo implementation can be accessed on SonarCloud.io, providing further insights into its performance. JaCoCo can be easily integrated with various tools, allowing users to take advantage of its capabilities right from the start. Contributions aimed at enhancing its implementation and introducing new features are welcomed from the community. While there are several open-source coverage solutions for Java, the experience from developing the Eclipse plug-in EclEmma has highlighted that many existing tools are not ideally designed for integration purposes. One major drawback is that many of these tools cater to specific environments, like Ant tasks or command line interfaces, and they often lack a comprehensive API that would allow for embedding in a variety of settings. This limitation in flexibility frequently prevents developers from effectively utilizing coverage tools across multiple platforms, creating a gap that JaCoCo aims to fill with its adaptable architecture. Ultimately, JaCoCo seeks to provide a more versatile solution for developers looking for robust code coverage tools.
