Scalatest 的 Wiremock 集成问题

Question

我在将 Wiremock 与 Scalatest 规范集成时遇到问题。我正在使用此版本的 Wiremock：

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

我创建了一个 WiremockSpec 看起来像这样的：

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

}

然后混入我的规范如下：

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

当我运行测试时，我得到这个错误：

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

我尝试了 this 解决方案，但我仍然遇到同样的错误。有人知道为什么会这样吗？我怀疑这可能是因为特征被初始化的方式？

Answer 1

最终追踪到 PlaySpec 特征。用 FlatSpec 交换它可以避免与 wiremock 服务器启动发生冲突。和WordSpec一样，也是冲突的。 FlatSpec 工作正常。我仍然需要深入研究为什么会发生这种情况。
