OpenCover: Measure Code Coverage
An open source tool for measuring .NET program code coverage, allowing you to see executed and missed code during automated tests.
What is OpenCover?
OpenCover is an open source code coverage analysis tool for .NET applications. It works by instrumenting the target .NET assemblies during runtime to record which lines of code are executed. The coverage results can then be formatted into detailed reports.
Some key features of OpenCover include:
- Integrates with unit test frameworks like NUnit, xUnit.net and MSTest to show coverage of code executed during tests
- Supports branch coverage analysis to see if all paths of code logic have been tested
- Can filter coverage reporting by namespace, class, method or line to focus on specific app areas
- Formats results into detailed HTML reports viewable in a browser
- Command line interface for integration into build scripts and automation
- Free and open source under the Apache 2.0 license
Overall, OpenCover provides a way for .NET developers to get code coverage metrics and identify gaps in their test suites. It helps improve test quality and confidence in the code.
