The command line test runner ArtOfTest.Runner.exe accepts a settings.xml file using the test= and settings= command line parameters. Our documentation shows you how to set the common settings and web settings. But how do you set the WPF settings, specifically the DefaultApplicationPath? I tried this settings.xml file, but cannot get it to be recognized by the command line runner. The test will always use the project setting contained in the settings.aiis file. I checked the log for parsing errors, but none were reported. <?xml version="1.0" encoding="UTF-8"?> <configuration> <configSections> <section name="WebAii.Settings" type="ArtOfTest.WebAii.Core.SettingsConfigSectionHandler, ArtOfTest.WebAii" /> <section name="WebAii.Settings.Web" type="ArtOfTest.WebAii.Core.WebSettingsConfigSectionHandler, ArtOfTest.WebAii" /> <section name="WebAii.Settings.Wpf" type="ArtOfTest.WebAii.Core.Settings.WpfSettings, ArtOfTest.WebAii" /> </configSections> <WebAii.Settings.Wpf DefaultApplicationPath="E:\Users\Dad\Documents\visual studio 2010\Projects\TelerikWpfApp1\TelerikWpfApp1\bin\Debug\TelerikWpfApp1.exe" /> </configuration>
