如何在 Cucumber for Java 中使用参数类型代替正则表达式

问题描述

我有这个场景：

Scenario Outline: Client makes call to GET /entity with pagination
    When client calls /entity with <page> and <perPage>
    Then client receives status code of <status>

Examples:
  | page | perPage | status |
  | 1    | 5       | 200    |

这是生成的步骤定义：

import cucumber.api.java8.En;

@ContextConfiguration
@SpringBoottest(classes = App.class,webEnvironment = SpringBoottest.WebEnvironment.RANDOM_PORT)
public class EntityApiStepdefs implements En {
  
    public EntityApiStepdefs() {
    
        When("^client calls /entity with ([^\"]*) and ([^\"]*)$",(Integer page,Integer perPage) -> {
        
        }
        
    }
}

如何删除正则表达式并使用参数类型代替？

像这样：

"^client calls /entity with ([^\"]*) and ([^\"]*)$"

为此：

"client calls /entity with {string} and {string}" 
// or:
"client calls /entity with {int} and {int}" 

PS：我尝试时的错误是：“未定义的步骤引用”

这是完整的堆栈跟踪：

这是 IntelliJ 消息错误：

这些是我的黄瓜库（全部来自 info.cukes groupId）：

1. cucumber-java8 (1.2.5)
2. 黄瓜弹簧 (1.2.5)
3. cucumber-junit (1.2.4)

解决方法

您使用的是 Cucumber v1.2.5。 Cucumber expressions were introduced in v3.0.0。
