Isalathiso esikhawulezileyo sokuSebenza-ngokuSebenza ngokuBundla ngokufanayo

Esi sithuba sisebenza njengesikhokelo esikhawulezayo sesalathiso seGatling yovavanyo lwentsebenzo.

Ngaphambili, sibone indlela yokwenza cwangcisa iprojekthi yakho yeGatling ngolwakhiwo olusengqiqweni kwaye luqondakala lula.

Kule posi, sijonga eminye imizekelo kunye nokusetyenziswa kweminye imisebenzi eqhelekileyo yeGatling xa kusenziwa izikripthi zovavanyo lwentsebenzo.


Imizekelo yokugcwala ekuthethwa ngayo kwesi sithuba yile:



Ukulinganisa okulula

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))) }


Sebenzisa ummeli weHTTP

setUp(scenario('Proxy on')
.exec(http('World').get('https://devqa.io'))
.inject(atOnceUsers(1)))
.protocols(http.proxy(Proxy('proxy.company.net', 8080))) }

Kumzekelo ongentla, proxy.company.net yi-URL yommeleli kunye 8080 izibuko elibambayo.




Izicelo ze-HTTP

GET Isicelo

Isicelo esilula seGET esinemibuzo ebuzwayo

http('Get Gatling posts')
.get('https://devqa.io')
.queryParam('post', 'gatling')
.queryParam('category', 'performance testing')
.header('Accept-Language', 'en')

POST Isicelo

Isampulu POST yesicelo ngeefom zeefom, o.k.t. ukungenisa ifom:

http('POST with params')
.post('https://www.example.com/login')
.formParam('firstname', 'David')
.formParam('lastname', 'Brown')
.header('Accept-Language', 'en')

Isampulu POST isicelo esinefayile yokulayisha ekufuneka ibekwi src/test/resources/bodies

http('Post with file payload')
.post('https://example.com/users')
.body(RawFileBody('bodyFileName.json')).asJSON
.header('Content-type','application/json')


Imeko

Unqumamo

Phawula: Ukuze usebenzise ikhefu, kufuneka wongeze oku kungenisa
import scala.concurrent.duration.DurationInt


scenario('with secode pause')
// ...
.pause(2, 3) // will make a random pause of 2-3 seconds
.pause(2) // will make a fixed pause of 2 seconds
scenario('millisecond pause')
// ...
.pause(200.milliseconds) // fixed pause of 0.2 second


IiLuphu

scenario('repeat')
.repeat(3)( // repeat 3 times
exec(http('google').get('https://www.example.com'))
)


Ukufakwa kwabasebenzisi

val scn=scenario('Virtual users') setUp(
scn.inject(
nothingFor(4.seconds),
atOnceUsers(10),
rampUsers(10) over(5.seconds))

Ulwenyuko kuqoqoqsho

rampUsers(10) over(5.seconds)
// linear rampup
// 10 users added over 5 seconds (1 extra user every 500 ms)
constantUsersPerSec(10) during(5.seconds)
// adds 10 users every second
// (so a total of 50 users after 5 seconds)

Kanye

nothingFor(4.seconds) // no new users added during 4 seconds atOnceUsers(10) // 10 users added immediately // not really recommended since it can hammer down the tested server heavisideUsers(10) over(2.seconds) // better approximation of a peak of users

Ukutshekishwa kunye nokuQinisekiswa

KwiGatling, iitsheki zihlala zisetyenziselwa ukukhangela iikhowudi zempendulo zekhowudi, ngelixa amabango aqhele ukusetyenziselwa ukubamba ixesha leempendulo.

Itshekhi

Ukujonga imeko kunye nedatha yeJSON:

http('name').get('/path')
.check(status.is(200))
.check(jsonPath('$.name').is('some name'))

Ukugcina idatha yokuphendula kwiseshoni ye-Gatling

http('name').get('/path')
.check(header('location').saveAs('newLocation'))
.check(jsonPath('$.name').saveAs('name'))
// You can now use $newLocation and $name in your requests :
http('get home').get('/users/${name}')

Ukuqinisekisa

setUp(scn).assertions(
global.responseTime.mean.lt(50), // mean resp time < 50 ms
forAll.failedRequests.percent.gt(5) // for each request, < 5% failure )


Abaxhasi

Ukusetyenziswa okusisiseko

val feeder1 = Array(
Map('foo' -> 'foo1', 'bar' -> 'bar1'),
Map('foo' -> 'foo2', 'bar' -> 'bar2'),
Map('foo' -> 'foo3', 'bar' -> 'bar3') ) // repeating the values val feeder1a = feeder1.circular val feeder1b = feeder1.random // infinite entries with keys 'value1', 'value2' val feeder2 = Iterator.continually(Map('value1' -> 100, 'value2' -> 'toto')) // infinite random entries val feeder3 = Iterator.continually(Map(
'value1' -> Random.nextInt(100),
'value2' -> Random.alphanumeric.take(4)) ) // using the feeder to build the URLs scenario('scenario name')
.feed(feeder)
.exec(http('request name')
.get('/path/${value1}') )

Ukusetyenziswa okuphambili

// reading a csv file to build a feeder val feeder = csv('data.csv') // the csv file must have a header row which defines the keys and be comma (,) separated // filling a template file with the content of a feeder scn.feed(feeder).exec(
http('request name')
.post('https://www.example.com')
.body(ElFileBody('filename.xml')).asXML))
