scala - Wiremock Integration Issue with Scalatest

问题描述

I am having trouble integrating Wiremock with a Scalatest specification. I am using this version of Wiremock:

"com.github.tomakehurst"  %  "wiremock-jre8"       % "2.22.0"    % "test",

I created a WiremockSpec looks like this:

trait WiremockSpec extends BeforeAndAfterAll { self: Suite =>

  import WireMockConfiguration._

  protected val wiremockServer = new WireMockServer(options().dynamicPort())

  override protected def beforeAll(): Unit = {
    super.beforeAll()
    wiremockServer.start()
  }

  override protected def afterAll(): Unit = {
    wiremockServer.stop()
    super.afterAll()
  }

  // some helper methods

}

And then mix it into my specification as follows:

class MySpec() extends PlaySpec with Matchers with MockitoSugar with GuiceOneAppPerSuite
with ScalaFutures with WiremockSpec with IntegrationPatience

When I run the test, I get this error:

An exception or error caused a run to abort: Not listening on HTTP port. The WireMock server is most likely stopped 
java.lang.IllegalStateException: Not listening on HTTP port. The WireMock server is most likely stopped

I tried this solution but I still get the same error. Anybody know why this is happening? I am suspecting it maybe down to the way the trait is being initialised?

解决方案

最后追查到这个PlaySpec特质。将其替换为FlatSpec避免与wiremock 服务器启动发生冲突。与 相同WordSpec，它也会发生冲突。FlatSpec工作正常。我仍然需要深入研究为什么会发生这种情况。
