我试图在我的maven Java项目中运行各种web驱动程序(ChromeDriver和HtmlUnitDriver)，但我遇到了我怀疑是maven依赖问题的错误。我想知道有没有人能帮我找出错误的来源?
下面是错误信息:
(ChromeDriver)
Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.chrome.driver system property; for more information, see http://code.google.com/p/selenium/wiki/ChromeDriver.

我已经检查了我的pom.xml文件(相关部分如下)，我仍然不确定问题出在哪里。

下面是我运行web驱动程序的测试类。
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
public class TestClass {
public static void main(String[] args){
WebDriver driver = new HtmlUnitDriver();
driver.get("http://www.google.com");
System.setProperty("webdriver.chrome.driver", "/Users/tank/Documents/workspace/chromedriver");
WebDriver webDriver = new ChromeDriver();
webDriver.get("http://www.google.com");
}
}
任何形式的帮助/反馈对可能的错误来源将不胜感激:)谢谢!
- 对于ChromeDriver，您必须安装另一个可执行文件，最简单的方法是下载它并将其添加到您的
PATH。 - 对于HtmlUnitDriver，您正在混合
selenium-htmlunit-driver,selenium-chrome-driver和selenium-java的版本，所有它们都应该是完全匹配的，所以您没有冲突的依赖关系。此外，您不应该显式地添加commons-httpclient，因为它可能与已经定义的依赖冲突。
我只会依赖selenium-chrome-driver和selenium-htmlunit-driver在你的情况下，没有任何其他。
试着找到真正的问题所在，调试代码，不要使用maven。
