Isofthiwe yokuhlola Regression. Kuyini ekuhlehleni ukuhlolwa

Uma udala isofthiwe eliphezulu, akumelwe nje bhala umugqa ikhodi, kodwa futhi ukuze uqinisekise azikho amaphutha kuyo. Futhi uma iphutha bakudala ezitholakala ngezilimi eziningi ngisho ngesikhathi zihlanganise, eyinkimbinkimbi kakhudlwana kubalulekile ukubheka isikhathi eside lapho izinhlelo ezisebenzayo. Le nqubo ibizwa ngokuthi ukuhlolwa. Yena, ihlukaniswe yaba eziningana amagatsha, okuyinto ziyahlukahluka okuqukethwe kwabo futhi izici amaphutha. Njengengxenye sihloko ezocatshangelwa ukuthi ezifana ukuhlolwa ekuhlehleni. Yini Lalimeleleni? Iluphi uvivinyo akhona? Kungenzeka yini ukuba ukushintsha? Ngakho, liyini ekuhlehleni ukuhlolwa? Asikhulume ngaphezulu.

Izinhlobo, izinhlobo, Amathrendi

Regression ukuhlolwa (ekuhlehleni ukuhlolwa) - is kokuhlola indlela, okuyinto ihlose ukuthola izinkinga ezihlukahlukene ezindaweni Sekuvele kufakazelwe izinhlelo. Lokhu kwenziwa hhayi ukuqiniseka yokugcina ngokungabi bikho izingxenye ze-non-ukusebenza ikhodi, futhi ukuthola futhi silungise ekuhlehleni izimbungulu. Ngaphansi baqonde izimbungulu engaveli ngesikhathi sokuloba izinhlelo, kanye ne ukwengeza izigaba olusha ikhodi noma ukulungiswa amaphutha ngaphambilini uzibophezele e-syntax ikhodi.

Efingqa bonke ngenhla, singaphetha ngokuthi injongo ekuhlehleni ukuhlolwa - qinisekisa ukuthi ukulungiswa izinkinga zangaleso kuzoholela izindawo ezintsha ikhodi kakade-ihlolwe. Kunezinhlobo ezimbili eziyinhloko ekuhlolweni:

1. Ukusebenza.
2. Nonfunctional.

Abakwazi njengenani:

1. Amaskriphthi.
2. Imisa.
3. Kits uqalisa.

Yini, eqinisweni, lubandakanya amasofutiwe ekuhlehleni ukuhlolwa? Umsebenzi 3 ezindaweni eziyinhloko. Okungukuthi ekuhlehleni:

1. Bugs.
2. izinkinga Old.
3. Imiphumela engemihle.

ukuhlolwa obusebenzayo

Basuke esekelwe nemisebenzi eyenziwa ohlelweni. Kwangathi ozoba ngomhlaka ingxenye, ukuhlanganiswa, uhlelo kanye amazinga ukwamukelwa. Letincenye letimbili letiyinhloko, okuyinto uyahlolwa:

• Okudingekayo.
• ngenkathi amabhizinisi esebenza.

Uma kusetshenzwa izidingo ezidingekayo ukwenza uhlu yini edinga ihlolwe. Kuyinto efiselekayo ukuhlonza kuqala izinto, ukunquma isiqondiso umsebenzi. Lokhu kuyadingeka ukuba indiva kukho konke ukusebenza ezibaluleke kakhulu. Lapho uhlola "izinqubo zebhizinisi" ligxile kubo, t. E. Zimo ziphathwa umsebenzi nsuku zonke.

Izinzuzo isheke obusebenzayo kumele zihlanganisa yokuthi isofthiwe kulingisa ukusetshenziswa langempela kohlelo. Kodwa kukhona nemibi: isibonelo, uhlelo kungase kube amenable ukuba ukuhlolwa ngokweqile. Libuye ukungenzi okungenzeka amaphutha enengqondo isofthiwe.

ukuhlolwa Non-obusebenzayo

Lezi zinhlobo ukuhlolwa okuhloswe ngaso kokuhlola zonke izakhiwo ukuthi musa ezihlobene imisebenzi uhlelo. nemingcele ezifana can kuzo:

1. Ukuthembeka. Ihlolwa izimpendulo ngayo ezimweni ezihlukahlukene hhayi enikeziwe.
2. Ukusebenza. ISEBENZA KANJANI LENDLELA, okuyinto amenable ukuba imithwalo ehlukahlukene.
3. Lula. Indlela elula ukusebenza isicelo kubuka yomsebenzisi.
4. Scale. ukushintsha ukuphakama izimfuneko bese ububanzi isicelo lapho esebenza ngabaqaphi ezahlukene.
5. Security. Iphephe kangakanani idatha yomsebenzisi, kanye ulwazi iziteshi ezahlukene yokudlulisela.
6. Ukuthwaleka. Ihlola ukuthi isicelo isebenza ezisekelweni ezahlukene, futhi uma kunjalo - zingaki.

Ayini izakhiwo kohlelo onokucwaningwa kulezi zimo? Linani selilonkhe lebantfu labange 4.

1. Ukuhlola ukufakwa. Ungene kanjani ukuphatha kahle ukubeka uhlelo kukhompyutha ukumisa, futhi uma kunesidingo futhi ususe. Quality kulungiselelwa kuvumela umsebenzisi ukunciphisa ingozi ukulahleka kwedatha noma ukwehla (eziya ziba zimbi) izicelo ukusebenza.
2. Ukuhlola ukusetshenziswa induduzo. Hlola isofthiwe ethuthukiswe ku Ukusebenziseka nokuphimisela ngokucacile umsebenzisi sekupheleni.
3. Ukucushwa sokuhlola. Kuhilela kokuhlola ukusebenza ohlelweni ngesikhathi ukufakwa izilungiselelo ahlukahlukene ohlelweni, kanye ukusebenzisa izilungiselelo yangaphakathi zohlelo.
4. Ukuhlola ngokwehluleka nokulungiswa kwesimo esidalekile. Iqinisekisa ngemva okuvela amaphutha. Uhlaziya Asabela kanjani izakhiwo zokuzivikela, kanye iyiphi idatha futhi kungakanani ukulondolozwa ekunqanyulweni ngokushesha isicelo.

Efingqa, kufanele kuphawulwe ukuthi, nakuba kusukela ukuhlolwa non-functional nokuhlolwa esizimele izicelo ngokwemibandela ukusebenza imisebenzi, angakhuluma ngezimfanelo ezifana ukuthembeka, ukusebenza, futhi i-software yokuvikela. Lezi nemingcele njani izinga lalolu hlelo futhi nganoma iyiphi indlela ushiye umbono umsebenzisi ezithile. Ngakho-ke, ukubaluleka kwalesi test akuyona esingaphansi ukuthi we sokusebenza.

Ezimweni Test

Ezimweni Test abizwa ngokuthi isheke kungenalutho ukuze isofthiwe. Zibizwa ngokuthi amathuluzi ukuhlolwa okuzenzakalelayo. Le software ekhethekile, ngawo Uchwepheshe ukudala, ukulungisa iphutha, engikhiphela futhi ihlaziya imiphumela isicelo qhaqha intuthuko enjalo:

1. izikripthi Test. Lezi zihlanganisa iqoqo imiyalelo eyenzelwe amasheke ngokuzenzekelayo izingcezu ehlukile software.
2. kits Test. Le nhlanganisela zokubhala okuvivinya izingcezu ezithile isofthiwe kukhona izinhloso ehlangene noma ezivamile sokusebenza.
3. Ukuhlola ukusebenza. Le nhlanganisela Amaskriphthi noma amasethi obehlukene kanyekanye ukusebenzisa ngenkathi kokuhlola hlelo.

Ezishintshayo ekuhlehleni ukuhlolwa

ezishintshayo zomsebenzi - omunye izisekelo lokuthuthukiswa kwabantu ekhulwini lama-21. Lona wesifazane wamthinta isihloko. Ngakho, ngaphansi lwesofthiwe ukuhlolwa ukuqonda inqubo yokuqinisekisa kwe-software, phakathi kwesikhathi lapho imisebenzi esemqoka kanye nemisebenzi ezinjalo njengesiqala ngazo, Ukuqalisa nokubulawa, kanye nokuhlaziywa nokudilivela imiphumela, abazenzi ngokuzenzakalelayo, usebenzisa amathuluzi afanelekile. Lesi senzo eyenziwa uchwepheshe obhekene ukudalwa, ukulungisa iphutha, nokusekela ukusebenza isimo test imibhalo, ukuhlolwa kits futhi instrumentation. Umsebenzi kungaba kwenziwe nge ezihlukahlukene isofthiwe, kuhlanganise ekuhlehleni ukuhlolwa kanye izinhlelo ezenzakalelayo.

ekuhlehleni izimbungulu

Ngaphansi le test ukuqonda izinkinga yokusesha kukhona ngokusemthethweni "zisusiwe," kodwa kukhona isizathu sokukholwa ukuthi basekhona. I engavamile walolu hlobo lokuhlolwa wukuthi kubalulekile ukuba uhlole konke izenzo ngento ethile e inhlanganisela ezahlukene. Eyokuqala ukuhlolwa umdlalo ngokoqobo, kubika inkinga isixazululiwe ngu mshini ngalo etholakele. Regression ukuhlolwa isakhiwo kulokhu kusiza ukuqinisekisa ukuthi azikho imiphumela emibi.

Regression amaphutha ubudala

Lokhu kubhekisela ukuhlonza izimo lapho izinguquko zesimanje ezenziwe ikhodi uhlelo, ukhansele bugfixes. Ngakho, baphinde baqale ukusebenza. Ngakho-ke, lapho senza izinguquko ikhodi isofthiwe ezidingekayo ukuqala inqubo yokuhlola kusukela ekuqaleni (abazazisayo, yebo, ukuthi kwakunezinkinga nokusebenza).

Regression isicinganani

Ngaphansi kwakhe ukuqonda isimo, lapho yamuva ikhodi ushintsho kwenye ingxenye isicelo esenziwe inoperative ezinye noma zonke ezinye izingxenye Uhlelo athuthukile. Njengoba inkomba khona izinkinga ezinjalo ukungabi ukusebenza eyodwa noma ngaphezulu ezingxenyeni ezithile zesimiso. Umsebenzi we umhloli ukuhlonza zonke izindawo inkinga.

Efingqa konke okulotshwe, ukuthi kungathiwani ekuhlehleni ukuhlolwa? Manje ngesihloko ukuthi akusafanele ibangele izinkinga. It uhlala kuphela ukuze balukhulume konke umkhuba.
