I run in browser tests for a wpf application. Now, while having opened one of the browsers with the application under test (IE, Chrome and FF) i need also to open a second browser screen (that needs to stay open during the testing of the cross browser testing). The additional browser is IE (as the application from which i need to compare with only runs in IE (silverlight)). How can I open the additional IE browser with the second appilication while doing cross browser testing on the three other browsers. SolvedRe: css class Try this (By.ClassName("ClassName"));
