How to proxy to mockserver with auth

[yschimke]

Describe the issue

I want to test a client handling of Proxy Auth using mockserver as both the proxy and the origin server.

But I can't get Auth to fail.

What you are trying to do

package okhttp3.containers

import assertk.assertThat
import assertk.assertions.contains
import java.net.HttpURLConnection
import java.net.Proxy
import java.net.URI
import okhttp3.containers.BasicMockServerTest.Companion.MOCKSERVER_IMAGE
import okio.buffer
import okio.source
import org.junit.jupiter.api.Test
import org.mockserver.client.MockServerClient
import org.mockserver.model.HttpRequest.request
import org.mockserver.model.HttpResponse.response
import org.mockserver.proxyconfiguration.ProxyConfiguration
import org.testcontainers.containers.MockServerContainer
import org.testcontainers.junit.jupiter.Container
import org.testcontainers.junit.jupiter.Testcontainers

@Testcontainers
class ProxyWithAuthTest {
  @Container
  val mockServer: MockServerContainer =
    MockServerContainer(MOCKSERVER_IMAGE)
      .withNetworkAliases("mockserver")

  @Test
  fun testUrlConnectionPlaintextProxied() {
    MockServerClient(mockServer.host, mockServer.serverPort).use { mockServerClient ->
      mockServerClient.withProxyConfiguration(
        ProxyConfiguration.proxyConfiguration(
          ProxyConfiguration.Type.HTTP,
          mockServerClient.remoteAddress(),
          "admin",
          "password"
        )
      )

      val request =
        request().withPath("/person")
          .withQueryStringParameter("name", "peter")

      mockServerClient
        .`when`(
          request,
        )
        .respond(response().withBody("Peter the person!"))

      val proxy = Proxy(
        Proxy.Type.HTTP,
        mockServerClient.remoteAddress(),
      )
      val url = URI(mockServer.endpoint + "/person?name=peter").toURL()
      val connection = url.openConnection(proxy) as HttpURLConnection
      assertThat(connection.inputStream.source().buffer().readUtf8()).contains("Peter the person")
    }
  }
}

MockServer version

5.15.0

MockServer Log

I can provide, but nothing interesting, and I suspect I'm using API wrong.

I'm guessing with testcontainers this needs to be configured before starting

  @Container
  val mockServer: MockServerContainer =
    MockServerContainer(MOCKSERVER_IMAGE)
      .withNetworkAliases("mockserver")
      .withCopyToContainer(
        MountableFile.forClasspathResource("/proxy-config.properties"),
        "/config/mockserver.properties"
      )
      .withLogConsumer {
        println(it.utf8StringWithoutLineEnding)
      }

But I'm still working on the correct config.
