'; scala - Gatling: Dynamically assemble HttpCheck for multiple Css selectors - LavOzs.Com

I am working on a Gatling test framework that can be parameterized through external config objects. One use case I have is that there may be zero or more CSS selector checks that need to be saved to variables. In my config object, I've implemented that as a Map[String,(String, String)], where the key is the variable name, and the value is the 2-part css selector.

I am struggling with how to dynamically assemble the check. Here's what I got so far:

val captureMap: Map[String, (String, String)] = config.capture
httpRequestBuilder.check( => {
    val varName = mapping._1
    val cssSel = mapping._2
    css(cssSel._1, cssSel._2).saveAs(varName)
  }).toArray: _* // compilation error here

The error I'm getting is:

Error:(41, 10) type mismatch;
 found   : Array[io.gatling.core.check.CheckBuilder[io.gatling.core.check.css.CssCheckType,jodd.lagarto.dom.NodeSelector,String]]
 required: Array[_ <: io.gatling.http.check.HttpCheck]
      }).toArray: _*

apparently, I need to turn my CheckBuilder into a HttpCheck, so how do I do that?

I managed to get it to work by introducing a variable of type HttpCheck and returning it in the next line:

httpRequestBuilder.check( => {
    val varName = mapping._1
    val cssSel = mapping._2
    val check:HttpCheck= css(cssSel._1, cssSel._2).saveAs(varName)
  }).toArray: _*

While this works, it's ugly as hell. Can this be improved?
