scalatest中的场景大纲

我正在使用scalatest实现我的测试框架，我认为我在使用这个框架而不是Cucumber时犯了一个错误

我试图使用一些特性作为黄瓜的场景大纲，以避免干裂

这是我的问题

  feature("Features of mus client") {
    scenario("GET message with mus client") {
      Given("a Musin message")
      val config: Properties = new Properties
      config.put("method", "POST")
      config.put("encoding", "UTF-8")
      config.put("uri", "http://localhost:9083/musClient")
      When("I make a request to f2e")
      val response = HttpClientTest.request(config, createJSON(READ))
      Then("The message it´s returned successfully")
      assert(response != null)
    }

    scenario("POST message with mus client") {
      Given("a Musin message")
      val config: Properties = new Properties
      config.put("method", "POST")
      config.put("encoding", "UTF-8")
      config.put("uri", "http://localhost:9083/musClient")
      When("I make a request to f2e")
      val response = HttpClientTest.request(config, createJSON(CREATE))
      Then("The message it´s returned successfully")
      assert(response != null)
    }

正如您所看到的，我有两个场景，其中99%是相同的步骤，但一个变量改变了请求

我也是选择scalatest而不是cucumber的人之一，cucumber对于meME来说太难了，无法编写功能文件，然后返回scala/java文件并进行相应更改。维护两个文件。我实际上玩过黄瓜爪哇，scala cucumber可能会更流利。无论如何，我喜欢scalatest，因为我的所有单元测试、组件测试和流测试都是如此

在类似您的情况下，如果属性在多个场景中是公共的，并且您不会在场景中发生变化，那么定义为公共属性就可以了，如下所示

class E2E extends FeatureSpec with GivenWhenThen {
  feature("Features of mus client") {

    Given("http config")
    val config: Properties = new Properties(){{
        put("method", "POST") //you are doing POST in both case by the way
        put("encoding", "UTF-8")
        put("uri", "http://localhost:9083/musClient")
     }}

    scenario("GET message with mus client") {

      When("I make a request to f2e")
      val response = HttpClientTest.request(config, createJSON(READ))

      Then("The message it´s returned successfully")
      assert(response != null)
    }

    scenario("POST message with mus client") {

      When("I make a request to f2e")
      val response = HttpClientTest.request(config, createJSON(CREATE))

      Then("The message it´s returned successfully")
      assert(response != null)

    }
  }
}

但是，您可能还希望对唯一发生更改的部分使用基于属性的检查，该检查在中非常流畅且可读

基于属性的签入scalatest如下所示，我正在测试两个不同的输入参数。您需要导入org.scalatest.prop.TableDrivenPropertyChecks_

基于两个给定属性，将有两种情况，

对于您来说，基于属性的测试将如下所示，希望没有编译错误：

import org.scalatest.prop.TableDrivenPropertyChecks._
import org.scalatest.prop.Tables.Table
import org.scalatest.{FeatureSpec, GivenWhenThen}

class PaulWritesSpecs extends FeatureSpec with GivenWhenThen {

  val requestResponse =
    Table(
      ("httpMethod", "requestType"),
      ("GET", READ),
      ("POST", CREATE))

  feature("Features of mus client") {

    forAll(requestResponse) { (httpMethod: String, requestType: String) => {

        scenario(s"$httpMethod message with mus client") {

          Given("http config")
          val config: Properties = new Properties() {{
            put("method", httpMethod)
            put("encoding", "UTF-8")
            put("uri", "http://localhost:9083/musClient")
          }}

          When("I make a request to f2e")
          val response = HttpClientTest.request(config, createJSON(requestType))

          Then("The message it´s returned successfully")
          assert(response != null)
        }
      }
    }
  }
}
