QUESTION

Karate-Gatling: Not able to use object fields inside Karate features

Asked 2022-Apr-11 at 17:08

For the following Gatling simulation

class DeviceSimulation extends Simulation {

  var devices: List[Device] = List[Device]()

  before {
    // Preparing data.
    devices = DataFetch.getDevices()
  }

   // Feed device
  val devicesFeederCont: Iterator[Map[String, Device]] = Iterator.continually(devices.map(d => {
    Map("device" -> d)
  })).flatten
  val devicesFeederToKarate: ScenarioBuilder = scenario("feederDeviceToKarate").exec(karateSet("device", session => session("device").as[Device]))


  val Devices: ScenarioBuilder = scenario("Device")
    .feed(devicesFeederCont)
    .exec(devicesFeederToKarate)
    .exec(karateFeature("classpath:features/device/Devices.feature"))

  setUp(
    Devices.inject(rampUsers(5).during(5 seconds))
  ).protocols()
}

I would like to be able to inject Device object inside my feature:

Feature: Device actions

  Background:
    * url 'https://server-host'
    * print 'Device obj: ', device


  Scenario: Device actions

    Given path '/api/device/name/', device.name
    When method GET
    Then status 200

But, although for the Background print I get: c.intuit.karate - [print] Device obj: Device(1234,989898989), for the GET request I have: GET /api/device/name/com.intuit.karate.graal.JsExecutable@333d7..

I mention that Device is just a case class with two fields: case class Device(id: Int, name: String).

Is there a way to properly use objects passed from feeder inside Karate features?

Right now we've tested only with primitive values passed into the Gatling session. It may work if you convert the data into a java.util.Map. So maybe your best bet is to write some toMap() function on your data-object. Or if you manage to emit a JSON string, there is a karate.fromString() helper that can be useful.

So please read the docs here and figure out what works: https://github.com/karatelabs/karate/tree/master/karate-gatling#gatling-session

You are most welcome to contribute code to improve the state of things.

Vulnerabilities

No vulnerabilities reported

Install graal

You can download it from GitHub, Maven.
You can use graal like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the graal component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .

Support

Please refer to the GraalVM website for documentation. You can find most of the documentation sources in the docs/ directory in the same hierarchy as displayed on the website. Additional documentation including developer instructions for individual components can be found in corresponding docs/ sub-directories. The documentation for the Truffle framework, for example, is in truffle/docs/. This also applies to languages, tools, and other components maintained in related repositories.
