如何使用TestNG框架和Jenkins运行Selenium测试

Question

我想使用Jenkins运行用TestNG框架编写的Selenium测试。

在jenkins job（Freestyle project）中配置的命令：

java -cp J:\taf\testng\*;J:\taf\workspace\TestNGExamples\bin;J:\automation\* org.testng.TestNG J:\taf\workspace\TestNGExamples\testng1.xml

注意：对于-cp argument，给定目录路径testng jar, test classes, and selenium jar

当我运行作业（Build Now选项）时，它被Selenium的create session活动打中并给出错误。

注意：

同样的命令运行 成功地 从运行时 的命令行 。

控制台输出的错误日志： （jenkins）

以下是测试课程：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

    public class SeleniumTests {

        @Test
        public void test1(){
            WebDriver driver = new FirefoxDriver();
            driver.get("http://www.google.co.in");
            driver.quit();
        }

    }

以下是testng1.xml：

<?xml version="1.0" encoding="UTF-8"?>

<suite name="Default suite">
  <test verbose="2" name="Default test">
    <classes>
      <class name="SeleniumTests"/>
    </classes>
  </test> <!-- Default test -->
</suite> <!-- Default suite -->

环境详细信息：

1. Jenkins-2.19.4（作为Windows服务）
2. Java-1.8
3. TestNG-6.8.5
4. 硒-3.0.1
5. Firefox-51
6. 壁虎-0.11.1
7. 操作系统-Windows 7-64位

Answer 1

这不是TestNG或Selenium问题。将Jenkins安装为Windows服务时，有时会发生此错误。在Tomcat或GlassFish之类的servlet容器中安装Jenkins，它应该会有所帮助。
