Working with GatlingHttpFunSpec

[Michael Reardon]

GatlingHttpFunSpec looks really interesting.  I've been trying it out and could use some advice. I'm able to have one spec save information to use in a second, but programmatically setting session variables for an EL template is eluding me. Below is a flawed example of what I'm attempting to do.

spec {
    http("Request Access token")
      .post("/oauth/token")
      .basicAuth(apiKey, apiSecret)
      .queryParam("grant_type", "password")
      .queryParam("username", "ad...@example.com")
      .queryParam("password", "password")
      .check(success, jsonPath("$.access_token").ofType[String].saveAs("accessToken"))
}

spec {

  // this doesn't work, but what would?
  exec(session => session.set("name", "Foo"))

  http("Create a foo")
    .post("/v1/foos")
    .header("Authorization", "Bearer ${accessToken}")
    .body(ElFileBody("postRequest_v1.json")).asJSON
    .check(status.is(201))
}

Often with this sort of test, I need to first make other requests to set up the test data.  Is it possible to use "HttpDsl" outside of a "spec" function for that?  For example, could the access token request above be made without it being in spec function (ideally in a "doIf" function)?

Thanks for any guidance,

Mike
