pageLoadTimeout in Selenium not working
提问by Bharat Nanwani
I am using below code using selenium in Java. I am adding pageLoadTimeout of 4 seconds, however, the driver continues to wait till the complete page is loaded. Any help?
我在 Java 中使用 selenium 使用以下代码。我正在添加 4 秒的 pageLoadTimeout，但是，驱动程序继续等待，直到加载完整页面。有什么帮助吗？
System.setProperty("webdriver.gecko.driver", System.getProperty("user.home") + "\Desktop\geckodriver.exe");
FirefoxBinary b = new FirefoxBinary(new File(System.getProperty("user.home") + "\desktop\Mozilla Firefox\firefox.exe"));
FirefoxOptions options = new FirefoxOptions().setBinary(b);
driver = new FirefoxDriver(options);
//driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
driver.manage().timeouts().pageLoadTimeout(4, TimeUnit.SECONDS);
driver.get("https://www.booking.com/hotel/in/the-taj-mahal-palace-tower.html?label=gen173nr-1FCAEoggJCAlhYSDNiBW5vcmVmaGyIAQGYATG4AQbIAQzYAQHoAQH4AQKSAgF5qAID;sid=338ad58d8e83c71e6aa78c67a2996616;dest_id=-2092174;dest_type=city;dist=0;group_adults=2;hip_dst=1;hpos=1;room1=A%2CA;sb_price_type=total;srfid=ccd41231d2f37b82d695970f081412152a59586aX1;srpvid=c71751e539ea01ce;type=total;ucfs=1&#hotelTmpl");

The solution to your pageLoadTimeoutissue would be to bump up your Seleniumversion to v3.5.0. Here is effective code block and the resulted org.openqa.selenium.TimeoutException: Timeout loading page after 2000msof your own code in minimal lines:

回答by Gaurang Shah
if you specify the time, and selenium is not able to load the site is specified time, it will throw TimedoutException. You should handle that in your code.
如果您指定了时间，而 selenium 无法在指定时间加载站点，则会抛出TimedoutException. 你应该在你的代码中处理它。
driver.manage().timeouts().pageLoadTimeout(4, TimeUnit.SECONDS);
long startTime = System.currentTimeMillis();
try{
driver.get("https://yahoo.com");
}catch (TimeoutException te){
long estimatedTime = System.currentTimeMillis() - startTime;
System.out.println("it took "+estimatedTime+" Time");
}
if it's not throwing TimeoutException, either website has done loading within specified time or something is wrong with Selenium API.
如果它没有 throwing TimeoutException，则要么网站已在指定时间内完成加载，要么 Selenium API 出现问题。

WebDriver.Timeouts -> pageLoadTimeout(long time, java.util.concurrent.TimeUnit unit) Sets the amount of time to wait for a page load to complete before throwing an error.
WebDriver.Timeouts -> pageLoadTimeout(long time, java.util.concurrent.TimeUnit unit) 设置在抛出错误之前等待页面加载完成的时间。
pageLoadTimeout
页面加载超时
WebDriver.Timeouts pageLoadTimeout(long time,java.util.concurrent.TimeUnit unit)
Sets the amount of time to wait for a page load to complete before throwing an error. If the timeout is negative, page loads can be indefinite. Parameters: time - The timeout value. unit - The unit of time. Returns: A Timeouts interface.
设置在抛出错误之前等待页面加载完成的时间。如果超时为负，则页面加载可能是不确定的。参数： time - 超时值。unit - 时间单位。返回： 超时接口。
