java - WebDriverException : unknown error: failed to change window state to maximized, 当前状态对于 MacOSX 上的 ChromeDriver v2.43 和 Chrome 70 是正常的

Question

我的 macOS 刚刚将 chrome 自动升级到 v70，我相应地将 chromedriver 升级到最新版本，但是，由于调用时出现以下错误，我的 Selenium 自动化测试无法运行

tempDriver.manage().window().maximize();

错误信息是

org.openqa.selenium.WebDriverException: unknown error: failed to change window state to maximized, current state is normal

有什么想法吗？我知道 Selenium 的版本有点旧，但由于公司政策或其他原因，我无法升级它。

在问题解决之前，您可以通过以下方式绕过此问题:

自定义窗口大小

driver.manage().window().setSize(new Dimension(1920, 1080));

获取屏幕分辨率

Toolkit toolkit = Toolkit.getDefaultToolkit();
int width = (int) toolkit.getScreenSize().getWidth();
int height = (int) toolkit.getScreenSize().getHeight();

chrome 的参数

ChromeOptions options = new ChromeOptions();
options.addArgument("--start-maximized");

Javascript 执行器

((JavascriptExecutor) driver).executeScript("if(window.screen){
    window.moveTo(0, 0);
    window.resizeTo(window.screen.availWidth, window.screen.availHeight);
    };");
