##Chiyambi

Zomangamanga zamapulogalamu kwa nthawi yayitali zakhala gawo lofunikira kwambiri pakupanga mapulogalamu, zomwe zimakhudza mtundu wonse, kusamalidwa, ndi kusinthika kwadongosolo. Komabe, njira zachikhalidwe zamapangidwe a mapulogalamu nthawi zambiri zimabweretsa mapangidwe okhwima, osasinthika omwe angalepheretse kupanga mapulogalamu ndi luso. Spec Driven Development (SDD) imapereka yankho lodalirika pavutoli popangitsa kuti mapangidwe apulogalamu azitha kuchitidwa bwino komanso kuwongolera mayendedwe a mapulogalamu. M'nkhaniyi, tiwona momwe SDD imakhudzira mapangidwe a mapulogalamu, kufufuza zochitika ndi njira zothandizira, ndikupereka chithunzithunzi chokwanira cha ubwino ndi zovuta zomwe zimagwirizanitsidwa ndi njirayi.

Kodi Spec Driven Development ndi chiyani?

Spec Driven Development ndi njira yopangira mapulogalamu yomwe imagogomezera kukhazikitsidwa kwazomwe zingatheke ngati gwero lalikulu lachowonadi pamapangidwe a mapulogalamu. Njirayi imaphatikizapo kulemba mwatsatanetsatane, zoyesedwa zomwe zimafotokoza khalidwe lofunidwa la dongosolo, m'malo modalira zolemba zachikhalidwe kapena zojambula zapamwamba. Popanga zomwe zafotokozedwera, opanga amatha kuwonetsetsa kuti mapangidwe awo ndi olondola, athunthu, komanso ogwirizana ndi zofunikira zamakina.

Ubwino Wachitukuko Choyendetsedwa Mwapadera

Spec Driven Development imapereka maubwino angapo omwe amatha kusintha kamangidwe ka mapulogalamu ndikuwongolera luso laopanga:

1. Kuwongolera Kulondola ndi Kukwanira

Zomwe zingagwiritsidwe ntchito zimatsimikizira kuti mapangidwe ake ndi olondola komanso athunthu, kuchepetsa mwayi wa zolakwika ndi zosiyidwa. Izi zimabweretsa mapulogalamu apamwamba omwe amakwaniritsa zofunikira za omwe akukhudzidwa ndi ogwiritsa ntchito.

2. Kuchulukirachulukira

Mwa kupanga zomwe zikuyenera kuchitika, opanga amatha kupanga ntchito zambiri, monga kuyesa ndi kutsimikizira, zomwe zimasunga nthawi ndikuwonjezera zokolola.

3. Kugwirizana Kwabwino

Spec Driven Development imalimbikitsa mgwirizano pakati pa omanga, oyesa, ndi ogwira nawo ntchito popereka kumvetsetsa kwa machitidwe ndi zofunikira za dongosolo.

4. Kuchepetsa Ngongole Yaukadaulo

Mafotokozedwe ogwiritsiridwa ntchito amathandiza kuzindikira ndi kuthetsa ngongole zaukadaulo kumayambiriro kwa ntchito yokonza, kuchepetsa mwayi wokonzanso ndi kukonza zodula.

Maphunziro a Nkhani

Makampani angapo akwaniritsa bwino Spec Driven Development m'njira zawo zopangira mapulogalamu, ndikupeza phindu lalikulu komanso kukonza kamangidwe ka mapulogalamu.

1. Google's Spec-Driven Development

Google yakhala ikugwiritsa ntchito Spec-Driven Development kwa zaka zingapo, ndikuchita bwino kwambiri. Njira yawo imaphatikizapo kulemba mwatsatanetsatane, zomwe zingayesedwe zomwe zimalongosola khalidwe lofunidwa la dongosolo. Zolemba izi zimagwiritsidwa ntchito poyendetsa chitukuko, kuonetsetsa kuti chomaliza chimakwaniritsa zofunikira za omwe akukhudzidwa ndi ogwiritsa ntchito.

2. Microsoft's Spec-Driven Development

Microsoft yatenganso Spec-Driven Development mumapulojekiti awo, ndi zotsatira zabwino. Njira yawo imaphatikizira kugwiritsa ntchito kuphatikiza chilankhulo chachilengedwe komanso kuphunzira pamakina kuti apange mawonekedwe otheka kuchokera pazithunzi zapamwamba kwambiri.

Njira Zothandizira

Kukhazikitsa Spec Driven Development kumafuna kusintha kwakukulu m'malingaliro ndi ndondomeko, koma njira zingapo zingathandize:

1. Yambani Pang'ono

Yambani ndi pulojekiti yaying'ono kapena gawo linalake la dongosolo lalikulu kuti mudziwe zambiri ndikukulitsa chidwi.

2. Invest in Tooling

Sankhani zida zoyenera ndi matekinoloje oti zithandizire zomwe zingatheke, monga zinenero zamapulogalamu, zoyeserera, ndi makina owongolera mitundu.

3. Phunzitsani ndi Phunzitsani

Perekani maphunziro ndi maphunziro kwa omanga, oyesa, ndi okhudzidwa pa mfundo ndi machitidwe a Spec Driven Development.

4. Yang'anirani ndi Kusintha

Pitirizani kuyang'anira momwe ntchito ya Spec Driven Development ikugwirira ntchito ndikusintha njira yomwe ikufunika kuthana ndi zovuta ndi mwayi.

Code Chitsanzo

Nachi chitsanzo cha njira yosavuta yochitira mu Python:

# spec.py

def kuwonjezera (x, y):
    """Bweretsani kuchuluka kwa x ndi y"""
    kubwerera x +y

def test_add():
    """Yesani ntchito yowonjezera"""
    kuwonjezera (2, 3) == 5
    kuwonjezera (-1, 1) == 0
    kuwonjezera (-1, -1) == -2

ngati __name__ == "__main__":
    kuyesa_kuwonjezera ()

Khodi iyi imatanthauzira mawu osavuta akuti onjezani omwe amatenga mfundo ziwiri ndikubweza kuchuluka kwake. Ntchito ya test_add imayesa ntchito ya add yokhala ndi zolowetsa zingapo ndi zotulukapo zoyembekezeredwa. Chotchinga cha ngati __name__ == "__main__": chimayendetsa ntchito ya test_add pamene script ichitidwa mwachindunji.

# Kuwona

Nachi chitsanzo cha tchati chomwe chikuwonetsa zabwino za Spec Driven Development:

Tchatichi chikufanizira ubwino wa chitukuko cha chikhalidwe ndi Spec Driven Development, kusonyeza kuti Spec Driven Development imapereka kusintha kwakukulu pakulondola, zokolola, mgwirizano, ndi ngongole zaukadaulo.

##Mapeto

Spec Driven Development imapereka yankho lodalirika pazovuta zamapangidwe a mapulogalamu, ndikupangitsa kuti ikhale yotheka komanso kuwongolera mayendedwe a mapulogalamu. Polemba mwatsatanetsatane, zoyezetsa zomwe zimalongosola khalidwe lofunidwa la dongosolo, opanga amatha kuonetsetsa kuti mapangidwe awo ndi olondola, athunthu, ndi ogwirizana ndi zofunikira za dongosolo. Ndi maphunziro a zochitika ndi njira zogwiritsira ntchito, Spec Driven Development ikhoza kukhazikitsidwa bwino mu njira zopangira mapulogalamu, zomwe zimatsogolera ku mapulogalamu apamwamba, kuwonjezereka kwa zokolola, ndi mgwirizano wabwino pakati pa omanga, oyesa, ndi ogwira nawo ntchito.
