Test Runner

Item	Description
Shadow-copy assemblies being tested	This selector lets you enable copying assemblies that participate in tests to a temporary directory. This allows you to edit and rebuild test assemblies even while the related tests are running. You can choose between two options of shadow-copying: Native — enables shadow-copying mechanism of the test framework, which normally only copies assemblies. Advanced — this mechanism copies all files and subdirectories from the directories where the assemblies are compiled.
Run tests in AppDomain	This option applies to xUnit.net and NUnit tests and lets the test runner start each test assembly in its own Application Domain. It may come in handy in the following situations: You need to use different app.config files for different test assemblies. You use reflection in tests.
Check for hanging test execution	By default, ReSharper notifies you if there is no response from the test execution process. You may want to disable or configure this option if there is some code that could take long when executing after tests are finished (SetupFixture TearDown, Class TearDown).
Environment variables	In this area, you can configure a list of Name-Value pairs of environment variables that would be passed to the process started by the unit test runner and to all its child processes. These environment variables will override variables with the same names defined in your system, if any. Depending on whether these environment variables contain sensitive information or not, you can save them either in the 'Solution personal' or in the 'Solution team-shared' settings layer. Note that you don't have to restart Visual Studio after adding new variables.
