Unit testing

JetBrains Rider helps discover and run, debug, cover, or profile unit tests . The following unit testing frameworks are supported:

• NUnit — JetBrains Rider installation includes 2 bundled test runners that support versions up to 2.7.1 and up to 3.15.5 correspondingly. Other versions up to 4.1.0 are supported and will be used if the corresponding NuGet package is installed in the project.

• MSTest V1 (Windows only, requires Visual Studio installed), V2 (.NET Core, cross-platform)

• xUnit

• Custom test frameworks that use VSTest and Microsoft.Testing.Platform.

  To enable support of these frameworks, select the corresponding checkboxes on the Build, Execution, Deployment | Unit Testing | VSTest page of JetBrains Rider settings Ctrl+Alt+S.

• bUnit - a testing library for Blazor components

• Unreal Engine testing framework

• Google C++ Testing Framework

• doctest unit testing framework

• Catch C++ test framework

• Boost.Test framework (v. 1.59 and above)

With JetBrains Rider, you can execute a single unit test, all tests in a test class, file, project or solution. You can also execute any number of tests combined in a test session.

Besides running and debugging unit tests, you can analyze code coverage of unit tests and run performance profiling of unit tests.

Before running coverage analysis or performance profiling, make sure that the PDB information exists for all target assemblies. The safest choice would be to build your code with the Debug build configuration.
