Calling scala method with a gatling scenario

[Nicolas Amini-Lamy]

Hi everybody !

I posted on stackoverflow but it seems it's a better approach to ask questions here. I really appreciate Gatling's team reactivity and help !

So, I have a simple function like :

    object Actions {
        def myAction() {
            //do some stuff
        }
    }

Is there a way to use this method as a scenario ? Like :

    val scn = scenario("My scenario").exec(Actions.myAction())

This code doesn't compile but I don't understand why.. it seams exec is waiting for a chain / scenario builder (or a validation object). 

Perhaps I've not enough scala skills for understanding key concepts in using Gatling...

Thks a lot !

[Stéphane Landelle]

> it seams exec is waiting for a chain / scenario builder (or a validation object). 

Yep, exactly. And here, you don't return anything (you use the deprecated procedure style).

procedure style:

def myAction() { //do some stuff }

equivalent to (proper method style, return Unit, ie nothing):

def myAction(): Unit = { //do some stuff }

What you should be doing:

def myAction(): ChainBuilder = { //do some stuff }

or (letting compiler infer return type)

def myAction() = { //do some stuff }

It seems you're trying to write some Scala code without any Scala very basics. if so, you really should have a look at the first chapters from Twitter's Scala school: https://twitter.github.io/scala_school/

[Nicolas Amini-Lamy]

Thks again for your help, in fact I wrote a "void" procedure because I don't know what I have to return :)

My function is now :

 object Actions {


  def notifyAllCompanies():ChainBuilder = {
      var i:Int = 0;
      for(i <- 0 to FeederUtils.companiesIterator - 1) {
        var currentCompany = FeederUtils.activeCompanies(FeederUtils.companiesIterator)


        if (FeederUtils.companiesIterator < FeederUtils.activeCompanies.size - 1) {
          FeederUtils.companiesIterator+=1
        } else {
          FeederUtils.companiesIterator=0
        }
        Actions.notifyCompanyEntries(currentCompany("activeCompanyName"));
        wait(2000);
      }
     
  }

In adding ChainBuilder return type I have a type mismatch error on "<-" operator.

You're right, I read first lines of this tutorial but it seems it's not enough :) Sorry for asking beginners questions, I'll try to read more carefully this guide ! 

[Stéphane Landelle]

Your for loop doesn't yield anything.

No offense, but you're really trying to jump right into the code while you don't know some basics about the language. So you're trying to write some random Java stuff and crossing fingers that it might somehow work.

Hold your horses, read some Scala tutorial and Gatling advanced documentation for a few hours and you'll be set!

I'm reading the doc, don't worry :) But I'm very surprised... why adding "ChainBuilder" return type shows an error with my loop ?

It seems that this notation is correct : I founded it here : http://www.tutorialspoint.com/scala/scala_for_loop.htm

For another script its working fine...

[Stéphane Landelle]

"Your for loop doesn't yield anything."

That's why I wrote :

 I'm looking for more information about ChainBuilder. I don't understand how exec works.

I'm not here demanding all-in-one solutions ;)

[Stéphane Landelle]

Gatling DSL components are immutable builders that are resolved once when the simulation is loaded. The build result is the actual scenario.

ChainBuilder wraps ActionBuilders, which are the steps. Amongst others, you can chain a ChainBuilder with another ChainBuilder, or an Action, with the exec method.

[Nicolas Amini-Lamy]

I read and read again your answer. I went to https://github.com/gatling/gatling/blob/master/gatling-core/src/main/scala/io/gatling/core/structure/Execs.scala to have a better understanding of Exec but it has no effect on my little brain :)

Perhaps my approach is too Java-oriented but I imagine that exec is waiting for a specific method to call and that ChainBuilder is a kind of interface. I read scala school first chapters and no idea comes to me.. is there a way to encapsulate scala code into ChainBuilder or I have to use exclusively gatling stuff ?

What I want to do is simple : I have two csv files. For each row of the first file, I want to call a method that parses second file and execute some code, knowing first file row value.

"notifyAllCompanies" parses first file and calls "notifyCompanyEntries" with row value. I don't think this it is possible to encapsulate both treatments into gatling builder.. am I wrong ? In addition, I thought this could be too spaghetti code.

[Stéphane Landelle]

> Perhaps my approach is too Java-oriented but I imagine that exec is waiting for a specific method to call

Absolutely not. exec takes an ActionBuilder or ChainBuilder parameter, period!

Read about the builder pattern: http://www.javaworld.com/article/2074938/core-java/too-many-parameters-in-java-methods-part-3-builder-pattern.html

> Perhaps my approach is too Java-oriented

No. Your approach is imperative programming oriented, based on mutability, and your problem lies here. It has nothing to do with the language but with the way your using it.

[Nicolas Amini-Lamy]

Thanks for builder pattern explanation : I think I understand theory.. so I have to create a custom ActionBuilder ? If I understand I have to write :

 class Test extends ActionBuilder {
  def testMethod(): ActionBuilder = {
     //Don't know how to return instance
  }
 }

Then using Test.testMethod() with exec ? I'm looking about abstract trait concept.

[Stéphane Landelle]

I think the only solution for now is that you share your code so I can fix it.

My class seems like that (I removed useless data for your comprehension) :

class MyClass extends Simulation {
 val machine = "machineName"
 
 val baseUri = "http://"+machine+"/baseUri";
 val uri="/wsdlPort"
 
 val httpProtocol = http
 .baseURL(baseUri)
 .disableWarmUp
 


 /**
 * CSV File record vectors
 */
 object FeederUtils {
    val socEntries = csv("entries.csv").records
   
    val activeCompanies = csv("companies.csv").records
    var companiesIterator = 0;
 }
 


 object Actions {


  /**
   * For each company, calls notifyCompanyEntries
   */
  def notifyAllCompanies() {
      var i = 0;

      for(i <- 0 to FeederUtils.companiesIterator - 1) {
        var currentCompany = FeederUtils.activeCompanies(FeederUtils.companiesIterator)


        if (FeederUtils.companiesIterator < FeederUtils.activeCompanies.size - 1) {
          FeederUtils.companiesIterator+=1
        } else {
          FeederUtils.companiesIterator=0
        }
        Actions.notifyCompanyEntries(currentCompany("activeCompanyName"));
        wait(2000);
      }
     
  }

 
  /**

   */
  def notifyCompanyEntries(companyName: String) {
    foreach(FeederUtils.socEntries, "record") {
                exec(flattenMapIntoAttributes("${record}"))
                .exec({session => session.set("codeSociete", companyName)})
                .exec(http("Notify ${codeEntree}")

                )}
  }
 
 }
 
 /**

What is "wait"? Why don't you use pause?

OMG, wait is indeed Object.wait!!!

I wrote wait but I couldn't test it because of my calling problem, so perhaps it was a bad suggestion from eclipse.. :)

Thanks for your code suggestions, I will analyze it tomorrow. How can we use scala methods with inheritance ?

- After some workaround -

Thanks for helping, script is not still working but you gave me some clues.

I have a stack overflow error because loop doesn't break, I don't know why. I'm working on it.

I don't understand return type inference : adding "=" lets compiler infer return type, it seems kind of magic because I'm never using ChainBuilder ! So at execution time, what object is returned and how exec uses it ?

Anyway, one again thanks for helping. I really appreciate. I thought it will be easier to understand scala basics and to use it with gatling.

[Nicolas Amini-Lamy]

More precision :

My CSV file contains : 

activeCompanyName
valA
valB

During debugging, for loop never ends and & behavior seems strange :

1  val notifyAllCompanies =
2     for (activeCompany <- activeCompanies)
3        yield Actions.notifyCompanyEntries(activeCompany("codeSociete"))

Line 2 is executed 2 times, then line 3 one time... and activeCompany contains each time the first record.

[Stéphane Landelle]

I don't understand return type inference : adding "=" lets compiler infer return type

No, it defines a method (returning something) instead of a procedure (returning nothing)

 

it seems kind of magic because

Magic doesn't exist in computer science.

 

Anyway, one again thanks for helping. I really appreciate. I thought it will be easier to understand scala basics and to use it with gatling.

Use the DSL first. Keep things simple. Then once you're proficient with the basics, learn Scala basics and customize.

This introduction looks fine: http://www.scala-lang.org/docu/files/ScalaTutorial.pdf

[Stéphane Landelle]

codeSociete on one side, activeCompanyName on the other one, really?

[Nicolas Amini-Lamy]

Sorry, It was a test I forgot changing it, it's not the problem.

Thks for link, I'm starting reading it. 

[Nicolas Amini-Lamy]

Hi,

I'm still looking for a stack overflow error, I reduced code, wrote loops differently and this simple code sample is not working :

class Test extends Simulation {
  val machine = "machine:port"


  val baseUri = "http://" + machine + "/ws/linkToWs";

  val httpProtocol = http
    .baseURL(baseUri)
    .

disableWarmUp


  object Actions {
    def testCount = {
      2
    }


    val test = repeat(Actions.testCount, "socId") {
      group("Test") {
        exec({ session => session.set("fieldName", "testValue") })
      }
    }


  }


  val scn = scenario("test").exec(Actions.test)


  setUp(
    scn.inject(atOnceUsers(1)).protocols(httpProtocol))


}

=> Problem is probably under my eyes but I don't see it :(

[Stéphane Landelle]

Could you provide the stacktrace, please?

I noticed that if I replace Actions.testCount call with an int, it's working.

[Nicolas Amini-Lamy]

Line 13 is :

  object Actions {

Line 18 : 

[Stéphane Landelle]

Replace Actions.testCount by testCount

 object Actions {

Line 18 : 

val test = repeat(2, "socId") {

[Pierre DAL-PRA]

And if you don’t prefix testCount by ‘Actions.’ ? (which is completely unnecessary, since testCount and test are defined in the same object, you don’t need to prefix it to access it)

[Nicolas Amini-Lamy]

Excellent ! What an idea... !

Do you understand this behaviour ? Stéphane, I know magic doesn't exist :) 

[Pierre DAL-PRA]

What is happening here is that you’re trying to access the object while it’s being initialised, hence a circular dependency.

If you’re familiar with Spring/CDI, imagine you’re trying to inject a component A inside that same component A.

It does not happens if you don’t prefix it because it doesn’t to access a fully built ‘Actions’ built while it’s being built.

Nothing magic here :)

objects are lazy initialized. This lazy initialization is implemented as a wrapper of the target instance and delegation. Search the internet for singleton implementations with double check locking in Java.

When you call Actions.something, you're actually calling the singleton holder, that initialize the singleton target, and then delegate.

Here, sequence is:

1. First Actions call
2. Singleton not yet initialized
3. Creating singleton, which means populating vals (instance members)
4. populating "test" val requires calling Actions.testCount
5. Singleton not yet initialized, as original singleton initialization is still in progress
6. Infinite loop

Thanks for your detailed explanations & help, I understand ! I'm moving on other Gatling's subjects now :) Perhaps an other topic soon but I'm taking care not flooding your group !
