NUnit.Framework.Internal.Commands.ApplyChangesToContextCommand

ContextSettingsCommand applies specified changes to the TestExecutionContext prior to running a test. No special action is needed after the test runs, since the prior context will be restored automatically.
namespace NUnit.Framework.Internal.Commands { internal class ApplyChangesToContextCommand : BeforeTestCommand { public ApplyChangesToContextCommand(TestCommand innerCommand, IApplyToContext change); } }
