Needed for unit testing. This ensures RavenDB will wait for non-stale results for any query.

NoStaleQueriesAllowed.cs

// somewhere in your test’s setup
documentStore.RegisterListener(new NoStaleQueriesAllowed());
 
public class NoStaleQueriesAllowed : IDocumentQueryListener
{
      public void BeforeQueryExecuted(IDocumentQueryCustomization queryCustomization)
      {
            queryCustomization.WaitForNonStaleResults();   
      }
}
