UNIT TESTING yog ib theem ntawm software kuaj qhov twg tus kheej units / Cheebtsam ntawm ib qho software raug kuaj. A chav tsev yog qhov tsawg tshaj plaws testable ib feem ntawm tej software. Nws feem ntau muaj ib lossis ob peb inputs thiab feem ntau yog ib qho kev tso tawm. Hauv cov txheej txheem txheej txheem, a chav tsev tej zaum yuav yog ib qho kev pab cuam, kev ua haujlwm, txheej txheem, thiab lwm yam.
Ib yam li ntawd, chav ntsuas ntsuas nrog piv txwv yog dab tsi?
Chav ntsuas yog txhais raws li kuaj tus kheej chunks ntawm code npaj los ntawm developers siv cov ntaub ntawv muaj txiaj ntsig thiab siv tau. Piv txwv : Ib qho yooj yim piv txwv ntawm chav kuaj tuaj yeem yog thaum tus tsim tawm ua haujlwm / txoj hauv kev lossis nqe lus / voj rau xeem yog tias qhov program ua haujlwm zoo lossis tsis ua haujlwm.
Tsis tas li ntawd, koj yuav sau ib qho kev xeem li cas?
- 13 Lub Tswv Yim rau Kev Sau Cov Kev Xeem Ua Haujlwm Zoo.
- Ntsuas Ib Yam ntawm Ib Lub Sijhawm Hauv Kev Sib Tw.
- Ua raws li AAA Txoj Cai: Npaj, Ua, Qhia.
- Sau Yooj Yim "Fastball-Down-the-Middle" Kev Xeem Ua Ntej.
- Test hla ciam teb.
- Yog tias koj ua tau, sim tag nrho cov Spectrum.
- Yog ua tau, npog Txhua Txoj Kev Cai.
- Sau cov ntawv xeem uas nthuav tawm cov kab laum, tom qab ntawd kho nws.
Ib tug kuj yuav nug, dab tsi yog hom kev xeem chav tsev?
Chav ntsuas Cov txheej txheem: Black Box Kev sim - Siv qhov twg tus neeg siv interface, kev tawm tswv yim thiab cov zis raug sim. Lub thawv dawb Kev sim - siv los xeem txhua tus ntawm cov kev coj cwj pwm no raug sim. Grey Box Kev sim - Siv los ua kuaj , kev pheej hmoo thiab kev ntsuas kev ntsuas.
Chav ntsuas ntsuas yog dab tsi Vim li cas thiab peb siv nws li cas?
Chav ntsuas yog software kuaj methodology uas muaj kuaj ntawm tus kheej units ntawm qhov chaws code rau xyuas seb lawv yog haum rau ua siv los tsis. Lub hom phiaj tseem ceeb ntawm chav kuaj yog rau cais txhua feem ntawm qhov kev zov me nyuam thiab xyuas kom txhua feem ua haujlwm raug.

Dab tsi yog qhov txawv ntawm chav kawm sab hauv thiab cov chav nested?
Cov chav kawm uas tau tshaj tawm yam tsis siv qhov zoo li qub yog hu ua chav kawm sab hauv lossis chav kawm tsis zoo li qub. Cov chav kawm Staticnested yog chav kawm zoo li lwm cov tswv cuab zoo li qub ntawm cov chav kawm sab nrauv. Txawm li cas los xij, cov chav kawm sab hauv yog khi toinstance thiab nws tuaj yeem nkag mus rau cov tswv cuab ntawm pawg enclosingclass
Dab tsi yog txhais los ntawm chav kawm nkag mus hloov pauv?
Access modifiers (los yog access specifiers) yog cov lus tseem ceeb hauv hom lus taw qhia uas teeb tsa kev nkag mus tau ntawm cov chav kawm, txoj hauv kev, thiab lwm tus tswv cuab. Qhov no yog qhov feem ntau siv specifier rau cov chav kawm. Ib chav kawm tsis tuaj yeem raug tshaj tawm tias yog tus kheej
Dab tsi yuav tsum tau kuaj hauv chav kuaj?
UNIT TESTING yog ib theem ntawm kev sim software uas ib tus neeg/cov khoom ntawm cov software raug kuaj. Lub hom phiaj yog los xyuas kom meej tias txhua chav ntawm lub software ua tau raws li tsim. Ib chav tsev yog qhov tsawg tshaj plaws kuaj tau ib feem ntawm ib qho software. Nws feem ntau muaj ib lossis ob peb inputs thiab feem ntau yog ib qho kev tso tawm
Yuav ua li cas rau txim nyob rau hauv Is Nrias teb rau nyiag computer cov ntaub ntawv cov cuab tam los yog tej software qhov chaw code los ntawm ib tug neeg lub koom haum los yog los ntawm lwm yam txhais tau tias?
Kev piav qhia: Kev rau txim hauv Is Nrias teb rau kev nyiag cov ntaub ntawv hauv computer, cov khoom muaj nqis lossis ib qho software cov cai los ntawm ib lub koom haum, ib tus neeg, lossis los ntawm lwm txoj kev yog raug kaw 3 xyoo thiab raug nplua ntawm Rs. 500,000
Dab tsi yog txhais los ntawm hom ntaub ntawv muab los ntawm C ++?
Cov hom ntaub ntawv uas tau muab los ntawm cov ntaub ntawv tseem ceeb yog hu ua derived data types. Muaj nuj nqi, arrays, thiab pointers yog muab los ntawm cov ntaub ntawv hom hauv C programming lus. Piv txwv li, ib qho array yog muab los ntawm cov ntaub ntawv vim nws muaj cov hom ntaub ntawv zoo sib xws thiab ua raws li cov ntaub ntawv tshiab rau C
