package package_name
import io.gatling.core.Predef._
import io.gatling.http.Predef._

class PerformanceTest extends Simulation {
  private val httpConfiguration = http
    .baseURL(Configuration.baseUrl)
    .acceptEncodingHeader("gzip, deflate")
    .userAgentHeader(Configuration.userAgentName)
    .inferHtmlResources()
    .maxConnectionsPerHostLikeChrome
    .disableClientSharing
    .extraInfoExtractor(dumpSessionOnFailure)
}

其中配置是简单的 object Configuration { ... }

Gatling不会编译测试,并声明此错误消息:

[...]\performance-test\src\gatling\scala\package_name\performance\test\PerformanceTest.scala: 
could not find implicit value for parameter configuration: io.gatling.core.config.GatlingConfiguration
  private val httpConfiguration = http
                                  ^
one error found

如何解决此错误?

解决方案非常简单:我将包名(而不是文件的位置)更改为 performance_test (它是 com.company.performance.test

以下代码编译时没有错误:

src/test/scala/package_name/PerformanceTest.scala

package package_name

import io.gatling.core.Predef._
import io.gatling.core.session.Expression
import io.gatling.http.Predef._

object Configuration {
  val userAgentName: Expression[String] = "http://computer-database.gatling.io"
  val baseUrl: String = "Mozilla/5.0 (Windows NT 5.1; rv:31.0) Gecko/20100101 Firefox/31.0"
}

class PerformanceTest extends Simulation {
  private val httpConfiguration = http
    .baseURL(Configuration.baseUrl)
    .acceptEncodingHeader("gzip, deflate")
    .userAgentHeader(Configuration.userAgentName)
    .inferHtmlResources()
    .maxConnectionsPerHostLikeChrome
    .disableClientSharing
    .extraInfoExtractor(dumpSessionOnFailure)
}

生成.sbt

name := "gatlingdemo"

version := "0.1"

scalaVersion := "2.12.6"

libraryDependencies += "io.gatling" % "gatling-core" % "2.3.1"
libraryDependencies += "io.gatling" % "gatling-http" % "2.3.1"

下面是一个快速的开始: https://gatling.io/docs/2.3/quickstart/#gatling-scenario-explained

其中配置是简单的 object Configuration {} .

Configuration 不能只是 对象配置{} userAgentName 和 baseUrl

在我的例子中,我在模拟类中定义了如下变量

val configuration = ConfigFactory.load()..

导致了这个问题。。。带着同样的信息
