java - 如何使用 TestNG 框架和 Jenkins 运行 Selenium 测试

Question

我想使用 Jenkins 运行在 TestNG 框架中编写的 Selenium 测试。

在jenkins job(Freestyle项目)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 参数，给出了 testng jar、测试类和 selenium jar 的目录路径

当我运行该作业(Build Now 选项)时，它在创建 Selenium session Activity 时遇到问题并给出错误。

注意:

当从命令行运行时，同样的命令运行成功。

来自控制台输出的错误日志: (jenkins)

下面是测试类:

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();
        }

    }

下面是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 -->

环境细节:

1. Jenkins - 2.19.4(作为 Windows 服务)
2. Java - 1.8
3. TestNG - 6.8.5
4. Selenium - 3.0.1
5. 火狐 - 51
6. 壁虎驱动程序 - 0.11.1
7. 操作系统 - Windows 7 - 64 位

Answer 1

这不是 TestNG 或 Selenium 的问题。当 Jenkins 作为 Windows 服务安装时，有时会发生此错误。在 Tomcat 或 GlassFish 等 servlet 容器中安装 Jenkins，应该会有帮助。
