How to run and debug unit tests

The C# extension currently supports running and debugging a unit test via CodeLens annotations on test methods. Just click the 'run test' or 'debug test' links:
- Because
dotnet test
will run the test code in a child process, it isn't possible to configure a "unit test debugging" configuration in launch.json - There currently isn't a VS Code command to run the current test, though there is an issue for this in the backlog.
- You can tweak debugging options for unit tests by opening your VS Code settings file (ex: File->Preferences->Settings on Windows), and configuring the
"csharp.unitTestDebuggingOptions"
setting. See example below. - If your unit tests are targeting .NET Framework instead of .NET Core, see Desktop .NET Framework for more information.
Example User Settings file with unit test debugging options:
{
"window.zoomLevel": 0,
"csharp.unitTestDebuggingOptions": {
"sourceFileMap": {
"c:\\example\\folder\\where\\library\\was\\built": "/folder/where/my/library/is/now"
}
}
}
