【问题描述】：

我正在使用 chrome webdriver 连接到嵌入式应用程序的 chrome webview。

下面的代码确实实例化了一个工作驱动对象，我可以在其中查询元素并发送密钥。但是，当我启动驱动程序时，我会在控制台中收到错误消息（如下所示）。

我希望能够解决错误/警告或至少抑制它们，因为它会导致我的测试输出出现可读性问题。

代码：

import { Builder, By, WebDriver } from 'selenium-webdriver';
import { Options } from 'selenium-webdriver/chrome';

async function loadWebDriver(): Promise<boolean> {
    const chromeOptions = new Options();
    chromeOptions.addArguments('--remote-debugging-port=' + REMOTEDUBUG_PORT);
    chromeOptions.setChromeBinaryPath(WEBVIEWPATH);
    console.log('start driver');
    try {
        driver = await new Builder()
            .forBrowser('chrome')
            .setChromeOptions(chromeOptions)
            .build();
        console.log('end driver');
        return true;
    } catch (error) {
        console.log(error);
        return false;
    }
}

结果：

start driver

有人知道发生了什么吗？

【解决方案1】：

对于遇到这种情况的其他人，事实证明“未加载语言环境资源”的错误来自本地目录中没有数据。我可以通过传递包含本地文件的路径来解决此问题：

chromeOptions.addArguments('--locales-dir-path=' + localsPath);

我仍在调查剩余的最后 2 个错误。
