空手道BDD框架抛NPE简单配置

Question

我试图使用空手道BDD框架在我的API套件上运行测试，我正在运行到一个NPE。据我所知，我没有错误配置任何东西，但我肯定我忽略了一些东西。鉴于下面的功能文件和任务运行，有没有我做错了什么？

更新：这一点也适用空手道0.2.9，但不是最新的当前0.5.0.2

特性文件：.../src目录/测试/资源/根/特征/ 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：.../src目录/测试/ JAVA /根/特征/神智/ 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;

@RunWith(Karate.class) 
@CucumberOptions(plugin = {"pretty", "html:target/cucumber"}) 
public class SmokeTest { 

    @BeforeClass 
    public static void beforeClass() {} 

    @AfterClass 
    public static void afterClass() {} 

}

您在实际使用beta版的输出。只要使用0.5.0，你会没事的。

BTW找到这个大感谢，被固定在发展分支：https://github.com/intuit/karate/issues/158

也不要看this tweet对于为什么在此之前/需要一步钩后
