Change SSL cert used in feeder per request?

[Maciej Grzymkowski]

Hi everyone, is it possible in Gatling to use feeder with different certificate for every request?

I've also asked this question on SO (http://stackoverflow.com/questions/28694659/gatling-change-ssl-cert-used-in-feeder-per-request), but a colleague pointed me to your google group.

Consider the test:

• for a number of users, each has a personal, unique certificate used for HTTPS connection,
• for every user, send a request, using that user's certificate.

Example implementation:

val feeder = Array(
  Map("data" -> data(user1_data),
    "gatling.http.ssl.trustStore.file" -> "/tmp/test-data/rb.jks",
    "gatling.http.ssl.trustStore.password" -> "password",
    "gatling.http.ssl.keyStore.file" -> "/tmp/test-data/user1.jks",
    "gatling.http.ssl.keyStore.password" -> "password"),

  Map("data" -> data(user2_data),
    "gatling.http.ssl.trustStore.file" -> "/tmp/test-data/rb.jks",
    "gatling.http.ssl.trustStore.password" -> "password",
    "gatling.http.ssl.keyStore.file" -> "/tmp/test-data/user2.jks",
    "gatling.http.ssl.keyStore.password" -> "password")
)
...
val scn = scenario.exec(reportableTest(
  repeat(feeder.length) {
    feed(feeder)
    .exec(http("test user personal data")
    .post(user_url)
    .headers(user_headers)
    .body(StringBody("${data}")).asJSON
    .check(
      status.is(201),
      header("Content-type").is("application/json"),
    )
}))

I did call: .disableClientSharing in scenario setup.

The weird behaviour is, it seems that only the first

"gatling.http.ssl.keyStore.file" -> "/tmp/test-data/user1.jks",

is processed. The next are not (even if I create another reportableTest). I've simply changed the order to see that in fact in both request the first "userX.jks" is being used.

Is this the normal behaviour? Is it a bug?

I'm running Gatling 2.1.4, the same behaviour occured in 2.1.2.

You get it wrong. You can use a different SSL config per virtual user, not per request.

Doesn't that mean that if each virtual user does one request and then exits, each will have a different SSL config?

Thanks for help! As it turned out, these lines:

val scn = scenario.exec(reportableTest(
  repeat(feeder.length) {
    feed(feeder)

caused all the feeder requests to be consumed by a single user, hence only on set of certs was used. Removing that, adding another user solved the issue (indeed, adding users helped).

Hi guys,

I am trying to feed certificates as part of HTTPS request as below  : 

  val feeder_Certificates = Array(

    Map( 

    "gatling.http.ssl.trustStore.file" -> "/user-files/Certificates/nft_truststore.jks",

    "gatling.http.ssl.trustStore.password" -> "password",

    "gatling.http.ssl.keyStore.file" -> "/user-files/Certificates/nft_keystore.jks",

    "gatling.http.ssl.keyStore.password" -> "password"))

  println(">> Running simulation for " + duration + " seconds <<")

  val ChannelSimulationScenario = scenario ("Channeltransactions")

    .feed(feeder_Certificates)

    .forever(

      pace(40 seconds, 80 seconds)

        .exec(App.InitialiseApp).pause(3 seconds, 7 seconds)

        .exec(api.validateToken).pause(3 seconds, 7 seconds))

In the session I can see the reference to the trustStore file & KeyStore file however the certificates doesn't get sent to the application. 

Session:

Session(Channeltransactions,4659084711907998562-0,Map(gatling.http.ssl.keyStore.password -> password, 764bba98-7210-45b7-9ca3-5f5f51f7b13f -> 1455688053256, gatling.http.ssl.trustStore.password -> password, gatling.http.ssl.keyStore.file -> /user-files/Certificates/nft_keystore.jks, d24fc830-f69e-4a66-86fd-592969d12ebd -> 0, timestamp.d24fc830-f69e-4a66-86fd-592969d12ebd -> 1455687995035, gatling.http.ssl.trustStore.file -> /user-files/Certificates/nft_truststore.jks),1455687995023,0,OK,List(ExitOnCompleteLoopBlock(d24fc830-f69e-4a66-86fd-592969d12ebd)),<function1>)

What could be wrong ? any help is appreciated
