* xunit unit tests * most pass with formatting * convert objects to xunit * remove nunit * format * merge fixes * switch objects to fluent assertions * update to fluent assertions * more FA * convert all to FA * Format * Fix tests * formatting * hopefully made credential test better * Catch more specific exception * use another more specific exception * Fix tests * update to xunit * update packages
