Best Code Coverage Tools for Freelancers

Parasoft C/C++test measures structural code coverage during unit, integration, and functional testing, supporting metrics including statement, branch, MC/DC, call, and object/assembly coverage. Coverage can be captured on host, simulator, or target hardware, and integrates with open-source frameworks like GoogleTest, Boost.Test, and CppUnit for teams using those instead of C/C++test's built-in framework. Results feed into Parasoft DTP for centralized, per-test coverage reporting and trend tracking across builds, helping teams both identify gaps and satisfy the coverage requirements mandated by standards like ISO 26262 and DO-178C.

dotCover is a .NET unit testing and code coverage tool that works right in Visual Studio and in JetBrains Rider, helps you know to what extent your code is covered with unit tests, provides great ways to visualize code coverage, and is Continuous Integration ready. dotCover calculates and reports statement-level code coverage in applications targeting .NET Framework, .NET Core, Mono for Unity, etc. dotCover is a plug-in to Visual Studio and JetBrains Rider, giving you the advantage of analyzing and visualizing code coverage without leaving the code editor. This includes running unit tests and analyzing coverage results right in the IDEs, as well as support for different color themes, new icons and menus. dotCover comes bundled with a unit test runner that it shares with another JetBrains tool for .NET developers, ReSharper. dotCover supports continuous testing, a modern unit testing workflow whereby dotCover figures out on-the-fly which unit tests are affected by your code changes.
