InitializationError而黄瓜运行JUnit测试

Question

package cucumber; 
import org.junit.runner.RunWith; 
import cucumber.api.CucumberOptions; 
import cucumber.api.junit.Cucumber; 

@RunWith(Cucumber.class) 
@CucumberOptions(
     format={"pretty"}, 
     features= "src/features/" 
     ) 
public class cucumberRunner { 

} 

使用：

• 黄瓜核心1.2.4
• 黄瓜的Java 1.2.4
• 黄瓜的junit-1.2.4
• junit-4.12
• Eclipse Mars.1
• java 8

问题是，你的班级位于包'黄瓜'。 要么重命名包或移动你的脚步，定义和其他胶水代码到一个子包像“cucumber.steps”和限制的胶水代码查找到这个包：

package cucumber; 
import cucumber.api.CucumberOptions; 
import cucumber.api.junit.Cucumber; 
import org.junit.runner.RunWith; 

@RunWith(Cucumber.class) 
@CucumberOptions(
    format={"pretty"}, 
    features= "src/features/", 
    glue = "cucumber.steps") 
public class cucumberRunner {}
