TDD pab tsim kom zoo dua modularized, extensible thiab saj zawg zog code. Test Tsav Kev Txhim Kho txoj hauv kev tsav cov pab pawg Agile los npaj, txhim kho thiab xeem cov me me yuav tsum tau ua ke nyob rau theem siab heev. Raws li txoj hauv kev no, cov tswv cuab cuam tshuam xa thiab ua tau zoo dua vim tias tau tsom mus rau lub tsev me me.
Ib yam li ntawd, tib neeg nug, qhov zoo ntawm kev sim tsav kev txhim kho yog dab tsi?
Ib tug ntawm qhov zoo ntawm kev sim tsav kev txhim kho yog qhov uas muab cov koom haum muaj peev xwm los hloov kho lawv cov software tsis tu ncua los daws cov kev xav tau ntawm kev lag luam tshiab lossis lwm yam tsis tau pom dua. Lub koom haum ua tiav yog ib qho uas tuaj yeem ua rau muaj kev hloov pauv ib puag ncig thiab hais txog kev txhim kho cov lus pom zoo nrog aplomb.
Ib yam li ntawd, qhov kev sim ntsuas puas ua kom muaj kev loj hlob? Chav ntsuas yog ib feem tseem ceeb ntawm txhim kho kev siv software. Qhov no suav nrog kev loj hlob sai vim feem ntau koj sau cov chav kuaj txawm ua ntej koj sau code thiab ces xeem koj code tawm tsam hais tias xeem.
Dhau li ntawm qhov no, vim li cas thiaj sim tsav kev txhim kho?
Lub tswvyim yooj yim ntawm TDD yog sau thiab kho qhov ua tsis tiav kuaj ua ntej sau tus lej tshiab (ua ntej kev loj hlob ). Qhov no yuav pab kom tsis txhob muaj qhov sib npaug ntawm cov lej thaum peb sau cov lej me me ntawm ib lub sijhawm kom dhau mus kuaj . ( Kev sim tsis muaj dab tsi tab sis cov kev cai uas peb xav tau xeem ua kom tiav lawv).
Cov theem ntawm kev sim tsav kev txhim kho yog dab tsi?
Liab, Ntsuab thiab Refactor yog peb Theem ntawm Kev Tshawb Fawb Kev Txhim Kho thiab qhov no yog cov kab ke uas tau ua raws thaum sau cov lej. Thaum ua raws li, qhov kev txiav txim ntawm cov kauj ruam pab kom koj muaj kuaj rau qhov code koj sau thiab koj tsuas yog sau cov code uas koj yuav tsum tau xeem rau.

Vim li cas Visual Basic hu ua qhov kev tshwm sim uas tau tsav lub programming?
Visual Basic. Ib hom lus programming thiab ib puag ncig tsim los ntawm Microsoft. Nws yog qee zaum hu ua hom lus uas tau tsav los ntawm kev tshwm sim vim tias txhua yam khoom tuaj yeem cuam tshuam rau cov xwm txheej sib txawv xws li nas nias
Vim li cas thiaj siv kev txhim kho sai sai?
Qhov ntawd yog qhov laj thawj tseem ceeb vim li cas software xav tau cov qauv kev txhim kho zoo kom ua tau zoo los ntawm kev tsim mus rau kev tshaj tawm. Kev txhim kho sai ntawm daim ntawv thov tau tsim rau lub hom phiaj no - txhawm rau tsim cov qauv sai sai rau kev sim ua haujlwm thiab cov yam ntxwv, tsis tas yuav txhawj xeeb txog qhov khoom kawg yuav cuam tshuam li cas
Puas yog kev kho dua tshiab RAM ua rau lub laptop sai dua?
Ntxiv RAM feem ntau yog qhov txiaj ntsig zoo tshaj plaws uas koj tuaj yeem ua kom lub khoos phis tawj qeeb qeeb.Thaum lub kaw lus ua haujlwm luv ntawm RAM, nws yuav tsum pauv cov ntaub ntawv dhau mus rau lub hard drive, uas tuaj yeem ua haujlwm qeeb qeeb. Cov thev naus laus zis tshiab muab kev ua haujlwm sai dua, tab sis feem ntau motherboards txais tsuas yog ib hom RAM
Vim li cas kaw lub khob apparatus yog ntau txhim khu kev qha dua li qhib khob?
Cov khob khob kaw ib txwm muab cov nqi qis dua rau qhov taw tes flash dua li lub khob qhib (feem ntau 5-10 ° C lossis 9-18 ° F qis dua) thiab yog qhov kwv yees zoo dua rau qhov kub ntawm qhov vapor siab mus txog qhov qis qis. Cov txheej txheem rau kev txiav txim qhov flash point ntawm cov kua yog teev nyob rau hauv ntau cov qauv
Yog vim li cas bulk sau yog sai dua nyob rau hauv Oracle?
Txij li thaum BULK COLLECT khaws cov ntaub ntawv hauv BULK, INTO clause yuav tsum muaj ib qho kev sib sau ua ke. Lub ntsiab kom zoo dua ntawm kev siv BULK COLLECT yog nws ua kom cov kev ua tau zoo los ntawm kev txo cov kev sib cuam tshuam ntawm database thiab PL / SQL cav
