运行 Cucumber JUnit 测试时出现初始化错误

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-java-1.2.4
• 黄瓜junit-1.2.4
• junit-4.12
• Eclipse Mars.1
• 爪哇 8

问题是您的课程位于“cucumber”包中。重命名包或将您的步骤定义和其他胶水代码移动到子包中，例如“cucumber.steps”，并将胶水代码的查找限制在此包中：

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 {}
