使用Maven Surefire進行並行Cucumber-JVM Selenium Grid測試

我一直在繞圈試圖弄清楚這一點，似乎幾乎不可能使用maven並行選項來對抗Selenium Grid羣集。使用Maven Surefire進行並行Cucumber-JVM Selenium Grid測試

我的跑步者基於標籤運行，應該選取5或6個功能文件。

我使用Cucumber for Java，使用Maven surefire 2.19和Junit。

到目前爲止，我對POM萬無一失的配置是這樣的： -

<profile> 
     <id>RunFeature</id> 
     <build> 
      <plugins> 
       <plugin> 
        <artifactId>maven-surefire-plugin</artifactId> 
        <version>${surefire.version}</version> 
        <configuration> 
         <threadCount>5</threadCount> 
         <parallel>methods</parallel> 
         <systemProperties> 
          <property> 
           <name>environmentName</name> 
          </property> 
         </systemProperties> 
         <includes> 
          <include>**/RunFeature.java</include> 
         </includes> 
         <testFailureIgnore>true</testFailureIgnore> 
        </configuration> 
       </plugin> 
      </plugins> 
     </build> 
    </profile>

我的亞軍是這樣的： -

@RunWith(Cucumber.class) 
@CucumberOptions(
     plugin = {"json:target/cucumber.json"}, 
     features = "classpath:", 
     glue = "classpath:", 
     dryRun = false, 
     strict = true) 

public class RunFeature { 

}

我正與與Maven運行： -

clean test -P RunFeature -D environmentName =「DEV」 -Dcucumber.options =「 - tags @runnable --tags @ testa - tags @testb 「

這是堆棧跟蹤： -

我不知道在哪裏可以從這裏走。

cucumber-jvm中的記者不是線程安全的，所以這不太可能。您可以嘗試使用多個跑步者進行分組測試，並在課堂級別配置並行執行。 我感覺真的很冒險，你可以嘗試這個重新實現黃瓜：https://github.com/jhorstmann/zuchini（免責聲明：由我創建） 文檔仍然缺乏，但它應該是主要兼容的，存儲庫中有一些示例。 –

另一個更容易（而不是更好）的解決方案可能是使用多個寫入不同報告的跑步者。每個功能文件都可以擁有自己的跑步者... – Dude

報告是嘗試並行化時的一個實際問題。我們創建了一個名爲zucchini的框架，它在並行測試執行和報告方面做了很多工作，並且與cucumber-jvm完全兼容。你可以看看它是否適用於你的應用程序

我們通過使用json報告器來解決報告問題，並允許每個並行線程創建自己的獨立json對象。然後，我們將所有json結果彙總成一個'超級'json。你可以看到，代碼here
