Boostadani waxay u adeegtaa hage tixraac deg deg ah oo loogu talagalay qalabka Gatling ee tijaabinta waxqabadka.
Markii hore, waxaan aragnay sida loo sameeyo abaabul mashruucaaga Gatling qaab macquul ah oo si fudud loo fahmi karo.
Mashruucan, waxaan ku eegaynaa tusaalooyin iyo adeegsi qaar ka mid ah howlaha guud ee loo yaqaan 'Gatling' marka la abuurayo qoraallada tijaabada waxqabadka.
Tusaalooyinka laysku haysto ee ku xusan boostadan ayaa ah:
import io.gatling.core.Predef._ import io.gatling.http.Predef._ class SimplestSimulation extends Simulation {
setUp(scenario('Homepage')
.exec(http('Home').get('https://devqa.io'))
.inject(atOnceUsers(1))) }
setUp(scenario('Proxy on')
.exec(http('World').get('https://devqa.io'))
.inject(atOnceUsers(1)))
.protocols(http.proxy(Proxy('proxy.company.net', 8080))) }
Tusaalaha kore, proxy.company.net
waa wakiilka URL iyo 8080
waa dekedda wakiilka
Codsi fudud oo GET ah oo leh xuduudaha weydiinta
http('Get Gatling posts')
.get('https://devqa.io')
.queryParam('post', 'gatling')
.queryParam('category', 'performance testing')
.header('Accept-Language', 'en')
Muunad POST codsi wata foomamka params gudbinta foom:
http('POST with params')
.post('https://www.example.com/login')
.formParam('firstname', 'David')
.formParam('lastname', 'Brown')
.header('Accept-Language', 'en')
Codsi muunad ah 'POST' oo wata faylalka lacag bixinta oo ay tahay inuu ku jiro src/test/resources/bodies
http('Post with file payload')
.post('https://example.com/users')
.body(RawFileBody('bodyFileName.json')).asJSON
.header('Content-type','application/json')
