Ubeka njani ulindelo kwiXcode? Ukuseta ulindelo kwi-Xcode sisakhono esibalulekileyo sokuqinisekisa ukuba ii-apps zethu ziziphatha kwaye zisebenza njengoko silindele. Ulindelo luyingxelo malunga nokuziphatha okulindelweyo kwekhowudi yethu, kwaye ukusetyenziswa kwayo kusinceda senze uvavanyo lweyunithi olusebenzayo ngakumbi kunye nokuphucula umgangatho wezicelo zethu. Kweli nqaku, siza kuphonononga ukuba singaseta njani na ulindelo kwi-Xcode kunye nendlela yokunyusa oku kusebenza ukuphucula inkqubo yethu yophuhliso. Funda ukuze ufumanise ukuba njani!

– Inyathelo ngenyathelo ➡️ Ulubeka njani ulindelo kwi-Xcode?

• Inyathelo lesi-1: Vula i-Xcode kwikhompyuter yakho. Ungafumana i icon yeXcode kwiLaunchpad okanye kwiFinder.
• Inyathelo lesi-2: Nje ukuba i-Xcode ivuliwe, khetha iprojekthi ofuna ukuseta ulindelo kuyo. Ungafumana iiprojekthi zakho kwifestile yasekhaya yeXcode.
• Inyathelo lesi-3: Kwipheyini yokukhangela ekhohlo, khetha ifayile ofuna ukuseta ulindelo. Oku kunokuba yifayile yekhowudi yomthombo okanye ifayile yovavanyo.
• Inyathelo lesi-4: Ngoku uku-Xcode umhleli. Phezulu kwefestile, uya kubona ibar yemenyu. Cofa imenyu ethi "Umhleli" kwaye emva koko ukhethe u-"Vumela uvavanyo."
• Inyathelo lesi-5: Emva kokwenza uvavanyo, yiya kwifayile yovavanyo okanye indlela ofuna ukuseta ulindelo kuyo.
• Inyathelo lesi-6: Beka ikhesa ngaphakathi kwendlela apho ufuna ukuseta khona ulindelo kwaye ucinezele iqhosha elithi "Ctrl + Space" ukuze uvule ukugqibezela ngokuzenzekelayo.
• Inyathelo lesi-7: Chwetheza "ulindelo" kukugqiba ngokuzenzekelayo kwaye ukhethe "yongeza (_ ifomathi: Umtya, iimpikiswano: CVarArg…, ifayile: StaticString, umgca: UInt)" ukhetho.
• Inyathelo lesi-8: Umzekelo wolindelo ngoku wenziwe kwifayile yakho yovavanyo. Ungayinika igama lobuhlobo usebenzisa i-syntax «vumela ulindelo = XCTestExpectation(inkcazelo: "Igama elichazayo")«, endaweni ye "Igama elichazayo" enegama ofuna ukuyisebenzisa.
• Inyathelo lesi-9: Okulandelayo, bhala ikhowudi ofuna ukuyivavanya eya kuvelisa ulindelo olusetayo.
• Inyathelo lesi-10: Wakuba ugqibile ukubhala ikhowudi yakho yovavanyo, lixesha lokuhambisa ngokulindelekileyo. Ukwenza oku, yongeza le khowudi ilandelayo kwenye indawo emva komgca wekhowudi eyenza ulindelo: "ukulindela.zalisekisa()"
• Inyathelo lesi-11: Ekugqibeleni, khangela ukulindela. Ungakwenza oku emva kwayo yonke imigca yekhowudi yovavanyo ngokongeza "linda (ye: [ulindelo], ixesha liphelile: ixesha_ngemizuzwana)«. Faka endaweni ethi "time_in_seconds" kunye nexesha ofuna ukulabela njengomda walo mayizaliseke ulindelo.

Imibuzo neempendulo

1. Ulubeka njani ulindelo kwi-Xcode?

Ukuseta ulindelo kwi-Xcode, landela la manyathelo:

1. Vula iprojekthi yakho kwi-Xcode.
2. Khetha iklasi okanye indlela ofuna ukuseta ulindelo kuyo.
3. Cofa ekunene kwaye ukhethe "Ifayile entsha."
4. Khetha "I-Cocoa Touch Unit Testing Bundle" kwicandelo "le-iOS".
5. Cacisa igama lefayile yovavanyo kwaye ucofe "Gcina."
6. Kwifayile yovavanyo, ngenisa iklasi ofuna ukuyivavanya.
7. Phambi kwendlela ofuna ukuyivavanya, yongeza inkcazo "@testable importYourProjectName".
8. Bhala ikhowudi yovavanyo kwaye usebenzise iklasi "XCTestExpectation" ukuseta ulindelo.
9. Emgceni apho kulindeleke ukuba ulindelo luzaliseke, fowunela ulindelo's "fulfill()" method.
10. Okokugqibela, xa kuvalwa indlela yovavanyo, fowunela indlela ethi “waitForExpectations(timeout: expectedTime)”.

2. Yintoni ukubaluleka kokumisela okulindelweyo kwiXcode?

Ukuseta okulindelekileyo kwi-Xcode kubalulekile kuba:

1. Ikuvumela ukuba uqinisekise ukuba ikhowudi iziphatha ngendlela elindelekileyo.
2. Inceda ekuboneni nasekulungiseni iimpazamo ezinokwenzeka kwikhowudi.
3. Yenza kube lula ukwenza iimvavanyo zeyunithi eziqinisekisa ukusebenza kwesicelo sakho.
4. Inika ukuzithemba kumphuhlisi eyazi ukuba ikhowudi yabo ihlangabezana neziphumo ezilindelekileyo.

3. Ngaba ndingabeka ulindelo oluninzi kwindlela enye?

Ewe, unokuseta okulindelweyo okuninzi ngendlela enye ngokulandela la manyathelo:

1. Yenza umzekelo we "XCTestExpectation" kulindelo ngalunye ofuna ukuseta.
2. Sebenzisa indlela ethi “waitForExpectations(timeout: WaitedTime)” kwindlela yovavanyo yokuvalwa.
3. Qinisekisa ukuba ubiza "fulfill()" indlela emgceni apho kulindeleke ukuba ulindelo ngalunye luzaliseke.

4. Ndingaqinisekisa njani ukuba bendilindele ukuba kufikelelwe okanye akunjalo?

Ukujonga ukuba ulindelo lufezekisiwe okanye akunjalo, unokulandela la manyathelo:

1. Sebenzisa indlela ethi “waitForExpectations(timeout: WaitedTime)” kwindlela yovavanyo yokuvalwa.
2. Ukuba ulindelo lufezekisiwe ngexesha elichaziweyo, uvavanyo luya kudlula ngempumelelo.
3. Ukuba ulindelo aluhlangabezwanga ngexesha elichaziweyo, uvavanyo luya kuphumelela.

5. Kufuneka ndikubeke ixesha elingakanani ulindelo?

Ixesha omele ukulimisela ukuba ulinde ulindelo luxhomekeke kwimeko yovavanyo kunye nexesha eliqikelelweyo eliza kulithatha ukuze ulindelo lufikelelwe. Unokuseta ixesha elifanelekileyo elivumela ukulindela ukuba kufikelelwe, kodwa alikude kakhulu ukulibazisa ixesha lokwenziwa kweemvavanyo.

6. Kwenzeka ntoni ukuba ulindelo alufikelelwanga ngexesha elimisiweyo?

Ukuba ulindelo aluhlangabezwanga ngexesha elimisiweyo, uvavanyo luya kusilela kwaye lubonise impazamo ebonisa ukuba ulindelo alufezekanga.

7. Ndingabeka ulindelo kuVavanyo lwe-UI kwi-Xcode?

Hayi, okulindelweyo kunokusetwa kuphela kuvavanyo lweyunithi, hayi uVavanyo lwe-UI. Kuvavanyo lojongano lomsebenzisi, ezinye iintlobo zobuchule zisetyenziselwa ukungqinisisa indlela yokuziphatha kunye nenkangeleko yojongano lomsebenzisi, njengokukhangela kunye nokuguqula izinto. kwisikrini.

8. Ngaba ndingabeka ulindelo kwiimvavanyo zentsebenzo kwi-Xcode?

Hayi, ulindelo alusetyenziswanga kuvavanyo lokusebenza. Kuvavanyo lwentsebenzo, ixesha lokwenziwa kwekhowudi enikeziweyo livavanywa ukuze kuqinisekiswe ukuba lihlangabezana neemfuno ezimiselweyo zokusebenza. Akuyomfuneko ukuseta okulindelekileyo kuba iziphumo zithelekiswa ngqo namaxabiso alindelekileyo.

9. Ngaba ndingabeka ulindelo kwiimvavanyo ze-UI ezizenzekelayo?

Hayi, ulindelo alusetyenziswanga kuvavanyo lwe-UI oluzenzekelayo. Kolu hlobo lovavanyo, ezinye iindlela kunye nobuchule zisetyenziselwa ukusebenzisana ne-interface yomsebenzisi kunye nokuqinisekisa ukuziphatha kunye nokubonakala kwayo.

10. Ndingalufumana phi ulwazi oluninzi malunga nokusebenzisa okulindelweyo kwi-Xcode?

Unokufumana ulwazi oluthe kratya malunga nokusebenzisa okulindelweyo kwiXcode kuxwebhu olusemthethweni lweApple kubaphuhlisi beXcode. Ukongeza, zininzi izifundo kunye nezixhobo ze-intanethi ezinokukunceda uqonde kwaye usebenzise ngokufanelekileyo okulindelweyo kuvavanyo lwakho kwi-Xcode.
