下面是我得到的错误。我已经多次更改ChromeDriver和Chrome的版本，但都无济于事。有人能找到解决这个问题的方法吗？junit 4.12硒版本3.141.59向所有致敬
C:Program FilesJavajdk-11.0.6binjava.exe"

由于在每个页面对象类中错误初始化Web驱动程序，您面临空指针问题，PageFactory是Selenium中内置的页面对象模型概念。除了注释，它还允许使用静态init方法初始化web元素。
您可以在每个页面对象模型中使用以下init方法：
public className(WebDriver driver){
this.driver = driver;
PageFactory.initElements(driver, this);
}
