What dotCover is
dotCover is a paid .NET unit-test runner and code-coverage tool from JetBrains. It reports statement-level coverage for C#, F#, and VB.NET applications targeting .NET Framework, .NET Core, .NET, Mono, and Mono for Unity. The tool integrates with Visual Studio 2010–2026 and JetBrains Rider 2018.2 or later. On Windows it works within either IDE; on macOS and Linux it is available only through Rider. MSTest, NUnit, and xUnit work out of the box, while MSpec requires a plugin. Continuous testing can rerun tests affected by code changes when files are saved, solutions are built, or a rerun is requested. Editor highlighting marks covered and uncovered code and shows whether covering tests pass. Hot Spots identifies methods combining high cyclomatic complexity with low unit-test coverage. Filters can target projects, namespaces, types, members, or attributes. Reports export to HTML, XML, JSON, and XML for NDepend. A 30-day trial is available, but there is no free plan.

Verdict
dotCover combines .NET test running with statement, unit-test, and application/manual coverage analysis. Its platform limits and bundled licensing matter when choosing it, but the trial allows a 30-day evaluation.
