Tsis tas li ntawd, dab tsi yog enzyme thiab jest?
Jest yog javascript testing moj khaum, tsim los ntawm cov neeg tsim khoom uas tsim cov tshuaj tiv thaiv. Jest tsis txwv rau cov txheej txheem ua haujlwm, nws yog lub hom phiaj dav dav javascript testing moj khaum. tab sis raws li nws yog los ntawm react developers ntau inclination yog muaj. Enzyme yog lwm lub moj khaum uas tau tsim tshwj xeeb los kuaj cov tshuaj tiv thaiv.
Tsis tas li ntawd, cov enzymes siv nrog jest li cas? Jest version 15 thiab nce vim qhov no, koj tsis tas yuav ntxiv ib qho tshwj xeeb configuration rau Jest rau siv nws nrog enzyme .

Tom qab ntawd, tsuas yog xav tau / import React, enzyme ua haujlwm, thiab koj lub module nyob rau sab saum toj ntawm cov ntawv xeem.
Tom qab ntawd, ib tus tuaj yeem nug, koj yuav kuaj cov tshuaj tiv thaiv li cas siv jest thiab enzymes?
Enzyme muab cov kuaj utility functions rau React cov khoom xws li ntiav, mount thiab render whereas Jest yog a xeem khiav thiab ib lub tsev qiv ntawv lees paub. Tsis muaj Jest , tsis muaj txoj kev khiav Kev kuaj enzyme . Enzyme adapter yuav tsum tau muab compatibility rau txawv Teb cov qauv.
Dab tsi cuam tshuam rau kev ua haujlwm enzyme?
Ob peb yam cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv enzymatic mus - kub , pH, enzyme concentration , substrate concentration , thiab muaj cov inhibitors lossis activators.
