Handling JSF

JSF requires a parameter named javax.faces.ViewState to be captured on every page and be passed in every POST request.

Adding a check for capturing the value and a param on very request would be very cumbersome. Hopefully, we can mutualize these operations.

Define factory methods for building JSF requests that would automatically perform those operations:

import com.excilys.ebi.gatling.core.session.EvaluatableString

val jsfViewStateCheck = regex("""id="javax.faces.ViewState" value="(.*)"""").saveAs("viewState")
def jsfGet(name: String, url: EvaluatableString) = http(name).get(url).check(jsfViewStateCheck)
def jsfPost(name: String, url: EvaluatableString) = http(name).post(url).param("javax.faces.ViewState", "${viewState}").check(jsfViewStateCheck)

You can then build your requests just like you're used to:

val scn = scenario("Scenario Name")
  .exec(jsfGet("request_1", "/showcase-labs/ui/pprUpdate.jsf").headers(headers_1))
  .pause(80 milliseconds)
  .exec(
    jsfPost("request_2", "/showcase-labs/ui/pprUpdate.jsf")
        .param("javax.faces.partial.ajax", "true")
        .param("javax.faces.source", "form:btn")
        .param("javax.faces.partial.execute", "@all")
        .param("javax.faces.partial.render", "form:display")
        .param("form:btn", "form:btn")
        .param("form", "form")
        .param("form:name", "foo"))
