Best Code Coverage Tools for NUnit

NCover Desktop is a Windows-based tool designed to gather code coverage data for .NET applications and services. Once the coverage data is collected, users can view comprehensive charts and metrics through a browser interface that enables detailed analysis down to specific lines of source code. Additionally, users have the option to integrate a Visual Studio extension known as Bolt, which provides integrated code coverage features, showcasing unit test outcomes, execution times, branch coverage visualization, and highlighted source code directly within the Visual Studio IDE. This advancement in NCover Desktop significantly enhances the accessibility and functionality of code coverage solutions. By measuring code coverage during .NET testing, NCover offers insights into which parts of the code were executed, delivering precise metrics on unit test coverage. Monitoring these statistics over time allows developers to obtain a reliable gauge of code quality throughout the entire development process, ultimately leading to a more robust and well-tested application. By utilizing such tools, teams can ensure a higher standard of software reliability and performance.

dotCover is a powerful code coverage and unit testing tool designed for .NET that seamlessly integrates into Visual Studio and JetBrains Rider. This tool allows developers to assess the extent of their code's unit test coverage while offering intuitive visualization features and is compatible with Continuous Integration systems. It effectively calculates and reports statement-level code coverage for various platforms including .NET Framework, .NET Core, and Mono for Unity. As a plug-in to popular IDEs, dotCover enables users to analyze and visualize coverage directly within their coding environment, facilitating the execution of unit tests and the review of coverage outcomes without having to switch contexts. Additionally, it boasts support for customizable color themes, new icons, and an updated menu interface. Bundled with a unit test runner shared with ReSharper, another JetBrains product for .NET developers, dotCover enhances the testing experience. It also supports continuous testing, allowing it to dynamically identify which unit tests are impacted by code modifications as they occur. This real-time analysis ensures that developers can maintain high code quality throughout the development process.
