我在pom.xml文件中更新了WebDrivermanager的依赖项。 虽然在下面运行我的本地代码似乎工作正常。
driver = new ChromeDriver(capability);
但是当我尝试使用RemoteWebDriver远程运行代码时，它失败并继续要求为浏览器添加二进制文件
URL remote_grid = new URL("http://" + seleniumHub + ":" + seleniumHubPort + "/wd/hub");
driver = new RemoteWebDriver(remote_grid, capability);
它抛出异常。

答案 0 :(得分：1)
实际上，WebDriverManager可以帮助设置Selenium Grid。这个过程如下：
public class BinarySearchTree {
DoubleLinkedList dL;
TreeNode root;
public BinarySearchTree() {
this.root = null;
this.dL=new DoubleLinkedList();
}
public void
tree2DList(TreeNode TN) {
if (TN == null) {
return ;
} else {
tree2DList(TN.left);
dL.insertLast((YourClassOfObjects)TN.getItem());
tree2DList(TN.right);
}
return;
}
）来完成此操作，也可以使用此https://angular.io/guide/forms#track-control-state-and-validity-with-ngmodel中的Java类。
