Automate muaj cov ntsaum
Txheej txheem cej luam:
Nyob rau hauv daim ntawv no peb yuav tham txog qhov muaj cuab tam ntsaum thiab siv yam tshuaj no npaum li cas peb yuav automate tau muaj mechanism rau java raws li daim ntaub ntawv. Nyob rau hnub no tus era ntsaum kuj yog ib feem ntawm txoj kev loj hlob java. Feem ntau cov neeg muas zaub xav kom muaj ib tsab ntawv xoovtooj kaw cia pab muaj li ib feem ntawm daim tauj qhov chaws. Yog vim li cas qhov no yog tus muab ntawm tus ntsaum kom tus neeg uas paub me ntsis scripting tau Meskas tus deployable binary tsis paub txog cov ntaub ntawv txhua huvsi simplicity.
Taw qhia:
Apache ntsaum yog ib tug muaj generic uas. Lub npe NTSAUM stands abbreviated rau 'Lwm zoo huv si Tool'. No uas zoo rau lub chaw tso dej 'Tsim' hauv UNIX tab sis yog DVR siv Java. Nws yog neeg siv lub binaries ntawm ib java raws li qhov chaws lub tsev thiab deploying tus binary generated rau ib tus neeg neeg rau zaub mov tshiab uas yog predefined. Nws kuj siv tau ua kom muaj javadocs rau lub chaws puag thiab coj lub tsev kuaj suite rau lub codebase tseem. Ntsaum nrog JUNIT pab tsim tawm los ua raws li txoj kev kuaj no uas tau tsim kev tsav.
Ntsaum yuav tsum tau Java compiler yuav muab ntsia tau nrog lub chaw kuj sib txawv thiab JAVA_HOME nrog rau nws cov hauj lwm tus nqi teev. Ntsaum siv ib XML tej ntaub ntawv los txhais tau cov muaj kev. Lub neej ntawd npe ntawm cov ntaub ntawv no yog build.xml. Ib co developers kuj siv lub zog ua ntaub ntawv thov namely build.properties txhais tau ib co khoom e.g. muaj pes tsawg version thiab lwm yam tsis muaj tej uas yuav tsum tau hloov txij ua ke mus ua ke raws li qhov yuav tsum tau.
Plahaum:
FEDORA: Nyob RHEL, NTSAUM yuav muab ntsia tau siv cov kev hais kom ua – yum nruab ntsaum los nws yuav muab ntsia tau siv lub rpm – kuv hais kom ua. Qhov no koj yuav tsum download tau tus ntsaum nws ua ntej.
DEBIAN: Nyob Ubuntu, NTSAUM yuav muab ntsia tau siv qhov hais kom ua – apt-mus nruab ntsaum.
Qhov rais: Ntawm ib puas ncig qhov rais peb yuav tsum download tau lub ant_<VERSION_NO>.cov ntaub ntawv zauv teb. No lub nras zauv teb yuav tsum tau muab rho tawm hauv lub ceev. Nplaub tshev no yuav tsum muab txhais tias yog ib qho chaw kuj sib txawv thiab ANT_HOME.
Muaj ntaub ntawv coj mus kuaj build.xml yog muaj raws li:

Automation siv NTSAUM:
Ntsaum qhia ib pab loj java developers. Yuav luag txhua java tsim tawm yuav nyiam muaj ib tsab ntawv uas tau saib xyuas khiav kuaj chav tsev thiab npaj lub binary tis tej ntaub ntawv uas yuav tsum deployed tus neeg rau zaub mov hauv tsab ntawv teev npe. Ntsaum thiab muab txoj kev khiav scripts suab uas yuav siv los ua kev kuaj chav tsev nyob rau ib qhov chaws puag. Yog li, Nws muab kev pab rau cov uas siv tau txoj kev kuaj no uas tau tsim kev tsav developers. Raws li peb paub hauv kuaj uas tau kev loj hlob vib this JUNIT tsav yog ib tug compulsion, Nws yog ib qho kom zoo dua nws yog tias peb muaj ib tsab ntawv xovtooj kaw lus uas sau tag nrho cov junit kuaj tus neeg mob nyob mus ib. Tsis zoo xwb tias tsab ntawv no tseem siv tau yog muaj peb muaj ib cov e.g nruam xws li tooled. Hudson. Peb coj cai nram qab no illustrates siv NTSAUM nrog JUNIT.
