Test Runner


Shadow-copy assemblies being tested	When this option is enabled, assemblies that participate in tests are copied 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 the shadow-copying mechanism of the test framework, which normally only copies assemblies. Advanced — by default, this mechanism copies all relevant files and subdirectories from the directories where the assemblies are compiled. When you select this option, the masks of the copied files appear in the File mask field, where you can further customize what should be shadow-copied.
If the test runner process does not exit after [x] seconds	These options let you configure the way JetBrains Rider decides when the test runner process is hung and what to do in that case.
If the spawned processes do not exit after [x] seconds	By default, JetBrains Rider maintains a list of all processes that are launched by the executed tests. If some of these processes do not exit after the test execution is over, JetBrains Rider will suggest you to terminate the process. These options let you configure the way JetBrains Rider decides when a spawned process is hung and what to do in that case. If you choose Ask what to do, you will be able to decide whether to terminate each spawned process that hung. JetBrains Rider will remember your choice and add processes to the list on this options page, so that you can later modify actions for each process.

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.

Test Settings

Specify a custom test settings configuration (.runsettings/.testsettings file within your solution).
