Gatling Newbie here. I am trying to check the html of my page using the below documented css selector. The css item is present on the page (verified with postman) but Gatling is not finding it. I receive a variable undefined error on compile. Any advice would be greatly appreciated.
import scala.concurrent.duration._
import io.gatling.core.Predef._
import io.gatling.http.Predef._
import io.gatling.jdbc.Predef._
class LoggingIn extends Simulation {
val httpProtocol = http
.baseURL("https://test.spidastudio.com")
.inferHtmlResources(BlackList(""".*\.js""", """.*\.css""", """.*\.gif""", """.*\.jpeg""", """.*\.jpg""", """.*\.ico""", """.*\.woff""", """.*\.(t|o)tf""", """.*\.png"""), WhiteList())
val headers_0 = Map(
"User-Agent"-> "Gatling",
"Accept" -> "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
"Accept-Encoding" -> "gzip, deflate",
"Cache-Control" -> "max-age=0",
"Origin" -> "https://test.spidastudio.com",
"Upgrade-Insecure-Requests" -> "1")
val headers_1 = Map("User-Agent"-> "Gatling","X-Requested-With" -> "XMLHttpRequest")
val uri1 = "https://test.spidastudio.com"
val scn = scenario("LoggingIn")
.exec(http("REQUEST A")
.post("/cas/login?service=https%3A%2F%2Ftest.spidastudio.com%2Fprojectmanager%2Fj_spring_cas_security_check")
//Defining variable LTValue
.check(css("input[name=lt]", "value").saveAs("LTValue"))
)
.exec(http("request_0")
.post("/cas/login?service=https%3A%2F%2Ftest.spidastudio.com%2Fprojectmanager%2Fj_spring_cas_security_check")
.headers(headers_0)
.formParam("username", "xxxxxxx.com")
.formParam("password", "xxxxxxxx")
//Calling variable
.formParam("lt", "${LTValue}")
Have you tried by removing this line from your code?
.inferHtmlResources(BlackList(""".*\.js""", """.*\.css""", """.*\.gif""", """.*\.jpeg""", """.*\.jpg""", """.*\.ico""", """.*\.woff""", """.*\.(t|o)tf""", """.*\.png"""), WhiteList())
or remove *.css""" ? Works?

Problem description
Current code is working, but it is using gcloud beta emulators pubsub from google/cloud-sdk for integration tests.
Integration tests are slow due to the size of the google/cloud-sdk image
pubsub emulator has to run on a fixed port, there seems to be no way to tell Micronaut which port the emulator is running on
I'll need to set the following environment variable in maven-surefire-plugin.
<environmentVariables>
<PUBSUB_EMULATOR_HOST>localhost:8085</PUBSUB_EMULATOR_HOST>
</environmentVariables>
How this can be done in Spring Boot
According to Test Containers | Gcloud Module, the correct way of implementing integration tests with PubSubEmulatorContainer in Spring Boot is like this:
https://github.com/saturnism/testcontainers-gcloud-examples/blob/main/springboot/pubsub-example/src/test/java/com/example/springboot/pubsub/PubSubIntegrationTests.java
This will bring up the container on a random port, and that is possible because of DynamicPropertyRegistry in Spring. It seems that Micronaut is missing this possibility.
Doc: https://www.testcontainers.org/modules/gcloud/
I'm looking for a working example of a JUnit5 or Spock integration test implemented in Micronaut 3.x that is using PubSubEmulatorContainer like described in the above doc.
Related doc: https://micronaut-projects.github.io/micronaut-gcp/latest/guide/#emulator
There are some comments on GitHub around configuring TransportChannelProvider. I'm able to inject an instance and inspect it, but I still haven't found out exactly what to do.
These are the closest leads so far:
https://github.com/micronaut-projects/micronaut-gcp/issues/257
https://github.com/micronaut-projects/micronaut-gcp/pull/259
TL;DR
We'll need to start the testcontainer first, get emulator host address and then call ApplicationContext.run like this:
applicationContext = ApplicationContext.run(
["pubsub.emulator.host": emulatorHost])
Small Github repo with example code: https://github.com/roar-skinderviken/pubsub-emulator-demo
Long answer with code
I finally managed to make a working solution using Micronaut 3.0.2 and Spock. A related Micronaut PR got me on track, together with this article: Micronaut Testing Best Practices https://objectcomputing.com/files/9815/9259/7089/slide_deck_Micronaut_Testing_Best_Practices_webinar.pdf
First a PubSubEmulator class (Groovy)
package no.myproject.testframework.testcontainers
import org.testcontainers.containers.PubSubEmulatorContainer
import org.testcontainers.utility.DockerImageName
class PubSubEmulator {
static PubSubEmulatorContainer pubSubEmulatorContainer
static init() {
if (pubSubEmulatorContainer == null) {
pubSubEmulatorContainer = new PubSubEmulatorContainer(
DockerImageName.parse("gcr.io/google.com/cloudsdktool/cloud-sdk:emulators"))
pubSubEmulatorContainer.start()
}
}
}
Then a fixture for PubSubEmulator (Groovy)
package no.myproject.testframework.testcontainers
trait PubSubEmulatorFixture {
Map<String, Object> getPubSubConfiguration() {
if (PubSubEmulator.pubSubEmulatorContainer == null || !PubSubEmulator.pubSubEmulatorContainer.isRunning()) {
PubSubEmulator.init()
}
[
"pubsub.emulator-host": PubSubEmulator.pubSubEmulatorContainer.getEmulatorEndpoint()
]
}
}
Then a specification class (Groovy) that starts the container, creates a topic and a subscription.
The clue here is to pass in pubsub.emulator.host as part of the configuration when calling ApplicationContext.run.
Remaining part of the code is very similar to the Spring Boot example I linked to in my question.
package no.myproject.testframework
import com.google.api.gax.core.NoCredentialsProvider
import com.google.api.gax.grpc.GrpcTransportChannel
import com.google.api.gax.rpc.FixedTransportChannelProvider
import com.google.cloud.pubsub.v1.SubscriptionAdminClient
import com.google.cloud.pubsub.v1.SubscriptionAdminSettings
import com.google.cloud.pubsub.v1.TopicAdminClient
import com.google.cloud.pubsub.v1.TopicAdminSettings
import com.google.pubsub.v1.ProjectSubscriptionName
import com.google.pubsub.v1.PushConfig
import com.google.pubsub.v1.TopicName
import io.grpc.ManagedChannelBuilder
import io.micronaut.context.ApplicationContext
import no.myproject.configuration.GcpConfigProperties
import no.myproject.configuration.PubSubConfigProperties
import no.myproject.testframework.testcontainers.PubSubEmulatorFixture
import spock.lang.AutoCleanup
import spock.lang.Shared
import spock.lang.Specification
abstract class PubSubSpecification extends Specification
implements PubSubEmulatorFixture, EnvironmentFixture {
#AutoCleanup
#Shared
EmbeddedServer embeddedServer
#AutoCleanup
#Shared
ApplicationContext applicationContext
def setupSpec() {
// start the pubsub emulator
def emulatorHost = getPubSubConfiguration().get("pubsub.emulator-host")
// start a temporary applicationContext in order to read config
// keep any pubsub subscriptions out of context at this stage
applicationContext = ApplicationContext.run()
def gcpConfigProperties = applicationContext.getBean(GcpConfigProperties)
def pubSubConfigProperties = applicationContext.getBean(PubSubConfigProperties)
def channel = ManagedChannelBuilder.forTarget("dns:///" + emulatorHost)
.usePlaintext()
.build()
def channelProvider =
FixedTransportChannelProvider.create(GrpcTransportChannel.create(channel))
// START creating topic
def topicAdminClient =
TopicAdminClient.create(
TopicAdminSettings.newBuilder()
.setCredentialsProvider(NoCredentialsProvider.create())
.setTransportChannelProvider(channelProvider)
.build())
def topic = TopicName.of(
gcpConfigProperties.getProjectId(),
pubSubConfigProperties.getTopicName())
try {
topicAdminClient.createTopic(topic)
} catch (AlreadyExistsException) {
// this is fine, already created
topicAdminClient.getTopic(topic)
}
// START creating subscription
pubSubConfigProperties.getSubscriptionNames().forEach(it -> {
def subscription =
ProjectSubscriptionName.of(gcpConfigProperties.getProjectId(), it)
def subscriptionAdminClient =
SubscriptionAdminClient.create(
SubscriptionAdminSettings.newBuilder()
.setTransportChannelProvider(channelProvider)
.setCredentialsProvider(NoCredentialsProvider.create())
.build())
try {
subscriptionAdminClient
.createSubscription(
subscription,
topic,
PushConfig.getDefaultInstance(),
100)
System.out.println("Subscription created " + subscriptionAdminClient.getSubscription(subscription))
} catch (AlreadyExistsException) {
// this is fine, already created
subscriptionAdminClient.getSubscription(subscription)
}
})
channel.shutdown()
// stop the temporary applicationContext
applicationContext.stop()
// start the actual applicationContext
embeddedServer = ApplicationContext.run(
EmbeddedServer,
[
'spec.name' : "PubSubEmulatorSpec",
"pubsub.emulator.host": emulatorHost
],
environments)
applicationContext = embeddedServer.applicationContext
}
}
Then a factory class (Groovy) for mocking credentials
package no.myproject.pubsub
import com.google.auth.oauth2.AccessToken
import com.google.auth.oauth2.GoogleCredentials
import io.micronaut.context.annotation.Factory
import io.micronaut.context.annotation.Replaces
import io.micronaut.context.annotation.Requires
import javax.inject.Singleton
#Factory
#Requires(property = 'spec.name', value = 'PubSubEmulatorSpec')
class EmptyCredentialsFactory {
#Singleton
#Replaces(GoogleCredentials)
GoogleCredentials mockCredentials() {
return GoogleCredentials.create(new AccessToken("", new Date()))
}
}
And finally, a Spock test spec.
package no.myproject.pubsub
import no.myproject.testframework.PubSubSpecification
import java.util.stream.IntStream
class PubSubIntegrationSpec extends PubSubSpecification {
def NUMBER_OF_MESSAGES_IN_TEST = 5
def DELAY_IN_MILLISECONDS_PER_MSG = 100
def "when a number of messages is sent, same amount of messages is received"() {
given:
def documentPublisher = applicationContext.getBean(DocumentPublisher)
def listener = applicationContext.getBean(IncomingDocListenerWithAck)
def initialReceiveCount = listener.getReceiveCount()
when:
IntStream.rangeClosed(1, NUMBER_OF_MESSAGES_IN_TEST)
.forEach(it -> documentPublisher.send("Hello World!"))
// wait a bit in order to let all messages propagate through the queue
Thread.sleep(NUMBER_OF_MESSAGES_IN_TEST * DELAY_IN_MILLISECONDS_PER_MSG)
then:
NUMBER_OF_MESSAGES_IN_TEST == listener.getReceiveCount() - initialReceiveCount
}
}
The chosen answer is a good deal more complicated than necessary, and it also contains numerous typos. A better answer can be found via the Micronaut GCP codebase itself, with the key bit being:
class IntegrationTestSpec extends Specification {
static CONTAINER_PORT = -1
static CredentialsProvider CREDENTIALS_PROVIDER
static TransportChannelProvider TRANSPORT_CHANNEL_PROVIDER
static PubSubResourceAdmin pubSubResourceAdmin
static GenericContainer pubSubContainer = new GenericContainer("google/cloud-sdk:292.0.0")
.withCommand("gcloud", "beta", "emulators", "pubsub", "start", "--project=test-project",
"--host-port=0.0.0.0:8085")
.withExposedPorts(8085)
.waitingFor(new LogMessageWaitStrategy().withRegEx("(?s).*Server started, listening on.*"))
static {
pubSubContainer.start()
CONTAINER_PORT = pubSubContainer.getMappedPort(8085)
CREDENTIALS_PROVIDER = NoCredentialsProvider.create()
def host = "localhost:" + IntegrationTest.CONTAINER_PORT
ManagedChannel channel = ManagedChannelBuilder.forTarget(host).usePlaintext().build()
TRANSPORT_CHANNEL_PROVIDER =
FixedTransportChannelProvider.create(GrpcTransportChannel.create(channel))
pubSubResourceAdmin = new PubSubResourceAdmin(TRANSPORT_CHANNEL_PROVIDER, CREDENTIALS_PROVIDER)
}
}
You'd then just extend that class anywhere you wanted to make use of PubSub. The following is slightly cleaner example that I came up with which manages creating a topic as well during test startup:
#Slf4j
abstract class PubSubSpec extends Specification implements TestPropertyProvider {
static final String cloudSdkName = System.getenv('CLOUD_SDK_IMAGE') ?: "gcr.io/google.com/cloudsdktool/cloud-sdk:emulators"
static final DockerImageName cloudSdkImage = DockerImageName.parse(cloudSdkName)
static final PubSubEmulatorContainer pubsubEmulator = new PubSubEmulatorContainer(cloudSdkImage)
static {
pubsubEmulator.start()
ManagedChannel channel = ManagedChannelBuilder.forTarget(pubsubEmulator.getEmulatorEndpoint()).usePlaintext().build()
try {
TransportChannelProvider channelProvider = FixedTransportChannelProvider.create(GrpcTransportChannel.create(channel))
CredentialsProvider credentialsProvider = NoCredentialsProvider.create()
TopicAdminClient topicClient = TopicAdminClient.create(
TopicAdminSettings.newBuilder()
.setTransportChannelProvider(channelProvider)
.setCredentialsProvider(credentialsProvider)
.build()
)
TopicName topicName = TopicName.of("project-id", "project-topic")
topicClient.createTopic(topicName)
} finally {
channel.shutdown()
}
}
#Override
Map<String, String> getProperties() {
[
"pubsub.emulator.host": pubsubEmulator.getEmulatorEndpoint()
]
}
}
I am working on demo for react diagram, i am using react webpack, but i am getting error in console,
ERROR in ./node_modules/storm-react-diagrams/dist/style.min.css 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
Here i have added my whole script of it, can anyone please look my code and help me to resolve this issue ?
App.js
import React from 'react';
import $ from "jquery";
import * as SRD from "storm-react-diagrams"
require("storm-react-diagrams/dist/style.min.css")
class App extends React.Component {
componentDidMount() {
// 1) setup the diagram engine
var engine = new SRD.DiagramEngine();
engine.installDefaultFactories();
// 2) setup the diagram model
var model = new SRD.DiagramModel();
// 3) create a default node
var node1 = new SRD.DefaultNodeModel("Node 1", "rgb(0,192,255)");
let port1 = node1.addOutPort("Out");
node1.setPosition(100, 100);

// 5) link the ports
let link1 = port1.link(port2);
// 6) add the models to the root graph
model.addAll(node1, node2, link1);
// 7) load model into engine
engine.setDiagramModel(model);

How to resolve this issue?
required: reactivemongo.api.DB
found : scala.concurrent.Future[reactivemongo.api.DefaultDB]
Not recommended
You can use Await to receive result from the Future and bind it.
Recommended
Use "play.modules.reactivemongo.ReactiveMongoModule"
http://reactivemongo.org/releases/0.12/documentation/tutorial/play.html
Example of configuration:
# The default URI
mongodb.uri = "mongodb://someuser:somepasswd#localhost:27017/foo"
# Another one, named with 'bar'
mongodb.bar.uri = "mongodb://someuser:somepasswd#localhost:27017/lorem"
Example of code
class MyComponent #Inject() (
val defaultApi: ReactiveMongoApi, // corresponds to 'mongodb.uri'
#NamedDatabase("bar") val barApi: ReactiveMongoApi // 'mongodb.bar'
) {
}
If you need to do your own binding, then just look at this example:

I am trying to put in place a unit test for websocket. From the doc, I should be able to use WS
See below a sscce
package com.streamingout
import akka.http.scaladsl.model.ws.TextMessage
import akka.http.scaladsl.server.Directives._
import akka.http.scaladsl.server.PathMatchers.Rest
import akka.http.scaladsl.testkit.{ScalatestRouteTest, WSProbe}
import akka.stream.scaladsl.{Flow, Sink, Source}
import org.scalatest.{FlatSpec, Matchers}
class Test extends FlatSpec with Matchers with ScalatestRouteTest{
//--------------- Flow ---------------
def flow = {
import scala.concurrent.duration._
val source = Source.tick(initialDelay = 0 second, interval = 1 second, tick = TextMessage("tick"))
Flow.fromSinkAndSource(Sink.ignore, source)
}
//-------------- Routing ------------
def route = {
path("/wskt") {
println("websocket ws")
handleWebSocketMessages(flow)
} ~
path(Rest) { pathRest =>
println("path Rest")
getFromFile(s"webapp/$pathRest")
}
}
// create a testing probe representing the client-side
val wsClient = WSProbe()
// WS creates a WebSocket request for testing
WS("/wskt", wsClient.flow) ~> route ~> check {
// check response for WS Upgrade headers
isWebSocketUpgrade shouldEqual true
}
}
When I run the test, I can see in my console the path Rest message, meaning that WS doesnt upgrade to Websocket.
Anyone knows what is wrong with my code?
I am using akka 2.4.7
Thank you
To make the above code work, in the route, the path /wkst should be without any leading slash
def route = {
path("wskt") {
println("websocket ws")
handleWebSocketMessages(flow)
} ~
path(Rest) { pathRest =>
println("path Rest")
getFromFile(s"webapp/$pathRest")
}
}
I am getting
Type mismatch: expected ReaperSpec.this.Register, actual: String
where expectMsg(...) is when using AkkaTest with ScalaTest as specified here
(http://doc.akka.io/docs/akka/snapshot/scala/testing.html)
What am I missing?
import akka.actor.{ActorSystem, Props}
import akka.testkit.{TestKit, TestProbe}
import system.Reaper.WatchMe
import org.scalatest.{BeforeAndAfterAll, MustMatchers, WordSpecLike}
class ReaperSpec(_system: ActorSystem) extends TestKit(_system)
with WordSpecLike with MustMatchers with BeforeAndAfterAll {
def this() = this(ActorSystem("Reaper"))
override protected def afterAll(): Unit = TestKit.shutdownActorSystem(system)
"A reaper" must {
"terminated when all child actors are stopped" in {
val probeA = TestProbe()
val probeB = TestProbe()
val reaper = system.actorOf(Props(classOf[Reaper]))
reaper ! WatchMe(probeA.ref)
reaper ! WatchMe(probeB.ref)
system.stop(probeA.ref)
system.stop(probeB.ref)
expectMsg("Dead")
}
}
}
Seems like I was using the wrong scala test version. I was using 3.0.0-M9. Changing it to 2.2.5 worked.
