Gatling-KT-Ext

Unholy Kotlin extensions to the Gatling Java API.

Async-await and generic code execution in your Java/Kotlin Gatling tests.

Most importantly, mutable builder syntax if you write your tests in Kotlin.

Mutable Builder Syntax

Instead of using Gatling's method chaining, you can use the mutable builder syntax, which is idiomatic in Kotlin, to write your tests.

ChainBuilder search =
    exec(http("Home").get("/"))
        .pause(1)
        .feed(feeder)
        .exec(
            http("Search")
                .get("/computers?f=#{searchCriterion}")
                .check(
                    css("a:contains('#{searchComputerName}')", "href").saveAs("computerUrl")
                )
        )
        ...

    +http("Search")

Note how the two http calls are in the same indentation level In the Kotlin code.
