Tizimli  testlashga  misol  qilib  “Omborga  „odshi‟nikning  kirishi”  ga‟i  testlash 

hodisasining 

spetsifikatsiyasida 

muhit(kiruvchi 

ma‟lumotlar) 

holati 

va 

tizimdagi(kutilayitgan natija) kutilayotgan ketma-ketlik  holati berilgan. Testlash hodisasi 

yo‟qotilgandan  so‟ng  biz  muhit  holatining  keltirilishi  orqali  tizimdagi  real  hodisalar 

ketma-ketligini  olamiz.  Haqiqiy  natijani  kutilayotgan  natija  bilan  solishtirish  orqali 

shunday  xulosaga  kelish  mumkin,  berilgan  testlash  hodisasida  tizimli  testlash  sinovi 

o‟tgan yoki o‟tmaganligini bilishimiz mumkin. Kutilayotgan natija sifatida tizim berilgan 

muhit  holati  uchun  funksionallashtirilgan  testlash  hodisasi  spetsifikatsiyasidan 

foydalanishimiz mumkin.

Shunday  bo‟lsada  ma‟lumotlar  hajmi  bu  bosqichda  shundayki,  samaraliroq 

yondashuv  testlash  moduli  yoki  kombinatsiyasi  bosqichida  o‟zgaruvchan  tizimli 

testlashga  nisbatan  murakkabroq  testlash  tizimini  yaratishga  olib  boruvchi  butun  yoki 

yarim avtomat testlash hisoblanadi. 

Tizimli  testlashning  asosiy  maqsadi  umuman  olganda  tizimdagi  funksional 

bo‟lmagan  talablarga  funksional  tekshiruv  hisoblanadi.  Bunda  tizim  resurslaridan 

noto‟g‟ri 

foydalanish, 

foydalanuvchi 

bosqichida 

ma‟lumotlar 

birlashmasi 

ko‟rsatilmaganligi,  tashqi  muhit  bilan  mos  kelmaslik,  foydalanish  senariysining 

ko‟rsatilmaganligi,  funksionallikning  noto‟grilgi  yoki  yo‟qligi,  foydalanishda 

noqulayliklar kabi kamchiliklar „aydo bo‟ladi. Risklarni minimallashtirish uchun u yoki 

bu tizim holatining asosi bilan bog‟lanish va testlash vaqtida mahsulot berilganidan so‟ng 

o‟rnatiladigan muhitga maksimal yaqinlashishdan foydalanishni tavsiya etadi. 

Tizimli testlashni 2 ta yo‟nalishga bo‟lish mumkin: 



  Talablar bazasi. Har bir talab uchun shu talab bajarilganligini tekshiruvchi testlash 

holati yoziladi. 



      Foydalanish holatlar bazasi. Mahsulotdan foydalanish usullarini ko‟rsatish asosida 

tizimdan  foydalanish  holati  yaratiladi.  Aniq  foydalanish  holati  bir  yoki  bir  necha 

senariylar orqali aniqlanishi mumkin. Har bir senariy tekshirilishida testlanishi lozim 

bo‟lgan test keyslar yoziladi.
