Jāatzīst, ka viegli nenākas, jo visi materiāli, kurus var atrast tīmeklī, stāsta par to, cik for&scaron;i ir testēt un rāda triviālus piemērus, bet trūkst materiālu par to, kā tie&scaron;ām iesākt testē&scaron;anu.</p> <p>&Scaron;obrīd esmu pārvarējis sākotnējās problēmas, un uzrakstījis pirmos testus <a href="http://dotnet.lv/blogs/ia/pages/draugiem-lv-api-net-iesai-ojums-wrapper.aspx">draugiem.lv iesaiņojumam</a>, kā arī atklājis vairākas interesantas lietas.
