FirefoxDriver: how to disable javascript,css and make sendKeys type instantly?
提问by KJW
While using FirefoxDriver to write tests,
在使用 FirefoxDriver 编写测试时，
I discovered loading of pages are really slow because of javascript and css being executed. IS there anyway to disable this ? possible to even install Noscript plugin to profile ?
我发现页面加载真的很慢，因为正在执行 javascript 和 css。无论如何要禁用它吗？甚至可以安装 Noscript 插件来配置文件？
additionally, sendKeys(), actually types out the text. however, this is quite slow for long text, anyway to instantly type all the string int othe input box ?
此外，sendKeys() 实际上是输入文本。然而，这对于长文本来说很慢，无论如何要立即在输入框内输入所有字符串？

You can disable javaScript in FirefoxProfile:
您可以在FirefoxProfile以下位置禁用 javaScript ：
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("javascript.enabled", false);
WebDriver driver = new FirefoxDriver(profile);
I do not think that there's a way to disable CSS and this not what you should do - this may break your web application, and disabling JavaScript may do this too.
我不认为有一种方法可以禁用 CSS，这不是您应该做的 - 这可能会破坏您的 Web 应用程序，而禁用 JavaScript 也可能会这样做。
There's no way to set the value of the text field directly - WebDriver is designed to simulate the real user "driving" the browser - that's why there's only sendKeys.
没有办法直接设置文本字段的值——WebDriver 旨在模拟真实用户“驱动”浏览器——这就是为什么只有 sendKeys。
However you can set the value of the element via JavaScript call (if you will not disable it, of course). This is faster for the long test, but this is not the emulation of the user interaction so some validations may not be triggered, so use with caution:
但是，您可以通过 JavaScript 调用设置元素的值（当然，如果您不禁用它）。这对于长时间的测试来说更快，但这不是用户交互的模拟，因此可能不会触发某些验证，因此请谨慎使用：
private void setValue(WebElement element, String value) {
((JavascriptExecutor)driver).executeScript("arguments[0].value = arguments[1]", element, value);
}
and use it:
并使用它：
WebElement inputField = driver.findElement(By...);
setValue(inputField, "The long long long long long long long text......");
