黃瓜和春季引導一體化有錯誤

Question

春季引導和黃瓜一體化，當我把這個項目打包成jar時使用mvn package命令併產生advvic-1.0.jar。但是，如果我運行這個jar

java -jar target/advvic-1.0.jar 

我得到這個錯誤：

造成的：cucumber.runtime.CucumberException：沒有發現後端。請確保您的CLASSPATH上有一個後端模塊。

但是，如果我解壓這個罐子，我發現lib文件夾黃瓜java.jar

這是我的POM：

Answer 1

我有一個春天啓動應用程序完全相同的問題，我想用作黃瓜測試的跑步者。

問題是Spring Boot以其自己的方式重新打包所有內容，因此很難讓默認的Cucumber ResourceLoaders找到任何cucumber.runtime.Backend類以及特性文件和步驟定義。

我最終做的是使用Spring特定的類來實現一個自定義cucumber.runtime.io.ResourceLoader來搜索類路徑。 我得到了這個想法在https://stackoverflow.com/a/17283721/3216618

PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); 
String locationPattern = ... use path and suffix to 
Resource[] resources = resolver.getResources(locationPattern); 

最後，你需要從發現org.springframework.core.io.Resource []

也許這可以幫助您創建一個可迭代：

 <plugin> 
      <groupId>org.springframework.boot</groupId> 
      <artifactId>spring-boot-maven-plugin</artifactId> 
      <configuration> 
       <requiresUnpack> 
        <dependency> 
         <groupId>info.cukes</groupId> 
         <artifactId>cucumber-java</artifactId> 
        </dependency> 
       </requiresUnpack> 
      </configuration> 
     </plugin>
