我正在尝试使用 Karate BDD 框架在我的 API 套件上运行测试，并且遇到了 NPE。据我所知，我没有错误配置任何东西，但我确信我忽略了一些东西。鉴于以下功能文件和任务运行器，我做错了什么吗？

更新：这适用于空手道 0.2.9，但不适用于当前最新的 0.5.0.2

功能文件：.../src/test/resources/root/feature/sanity.feature

Feature: Sanity Check
  As a developer
  I want to ensure that the test framework is active
  So that I can be confident I am testing correctly

  Background:
    * url httpBin

  Scenario: httpBin reflection
    Given path '/anything/foo/bar?baz=quux'
    When method GET
    Then status 200
    And match response contains { "args": {"baz":"quux"}}
    And match response contains { "method": "GET" }

驱动程序：.../src/test/java/root/feature/sanity/SmokeTest.java

package root.feature.sanity;

import com.intuit.karate.junit4.Karate;
import cucumber.api.CucumberOptions;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.runner.RunWith;

/**
 * Created by williamspaul on 8/29/17.
 */
@RunWith(Karate.class)
@CucumberOptions(plugin = {"pretty", "html:target/cucumber"})
public class SmokeTest {

    @BeforeClass
    public static void beforeClass() {}

    @AfterClass
    public static void afterClass() {}

}

mvn 测试输出

您实际上正在使用 beta 版本。只需使用 0.5.0 就可以了。

顺便说一句，非常感谢您发现这一点，已在开发分支中修复：https ://github.com/intuit/karate/issues/158

还请查看此推文以了解为什么需要此之前/之后步骤挂钩的详细信息
