java如何解决htmlUnit WrapsDriver错误

Question

我正在用HtmlUnit和selenium 3.13 jar运行测试，浏览器成功启动，但之后它停止工作，出现以下错误

有人知道怎么解决吗，我有 硒3.13 htmlUnit驱动程序2.33

下面是我的代码

driver = new HtmlUnitDriver();
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait
(10000,TimeUnit.MILLISECONDS);
logMsg("Browser launched successfully");
driver.get("WebURL");

Answer 1

您需要将htmlUnit驱动程序与依赖项一起使用，从github下载最新的htmlunit-driver-x.xx.x-jar-with-dependencies.jar，其中包括WrapsDriver类

Answer 2

关于你的测试环境的更多信息会让我们更清楚到底出了什么问题

但是，我没有看到您的代码块中存在任何重大问题。使用硒v3。14和HtmlunitDriver v2。33.0调用HtmlUnitDriver时，需要传递参数true以启用JavaScript，并且可以使用以下解决方案：

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class A_HtmlunitDriver_2_33_0 {

    public static void main(String[] args) throws InterruptedException {

    WebDriver driver = new HtmlUnitDriver(true);
    driver.manage().window().maximize();
    driver.get("https://stackoverflow.com/questions/53812207/how-to-resolve-htmlunit-wrapsdriver-error");
    System.out.println("HtmlUnitDriver invoked");
    driver.quit();
    }
}
