Kalibrate

A load testing framework for Kotlin

Session

This class will hold any runtime parameters you want to pass, as well as any runtime variables you need to store (ie auth tokens). Create a simple data class to hold these. It can be named anything.

data class Session(
    val scenario: String = "deploy",
    val test: String = "start",
    val baseUrl: String = ""
)

DSL

Your Kalibrate application will use a DSL starting your applicatino's main method:

@FlowPreview
@KtorExperimentalAPI
fun main(args: Array<String>) = kalibrate(args, { Session() }) { ... }

Jackson

Within the DSL, you can configure Jackson for serialization:

    jackson {
        registerModule(KotlinModule())
        disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)
    }

Arguments

To define command-line arguments, you can use ArgParser's DSL:

    sessionArgs {
        val scenario by it.storing("scenario name")
        val baseUrl: String by it.storing(
            "-u", "--url",
            help = "base url to use for requests"
        ).default("https://httpbin.org/get")
        Session(scenario = scenario, baseUrl = baseUrl)
    }

Agents

you define an httpAgent for each type of call you will make:

val get = httpAgent<GetResponse>(url = { "${it.baseUrl}?test=${it.test}" })
val post = httpAgent<PostResponse>(url = { "${it.baseUrl}/postEndpoint" }){
    header { "Authorization" to "Bearer ${it.token.orEmpty()}" }
    body { "sample body" }
}

Global http config

    globalHttpConfig {
        header { "Authorization" to "Bearer ${it.token.orEmpty()}" }
    }

Scenarios

Your application can contain many scenarios. You can define a function to use to determine which one to run for each execution:

scenarioChooser { it.scenario }
