Timeouts Interface in Selenium WebdriverPage Load Timeout in Selenium WebdriverSet Script Load timeoutTimeouts Interface in Selenium Webdriver

Timeouts interface manages all the waits of the driver instances; This is the inner Interface of Webdriver Interface; in other words, the Timeouts interface is enclosed by the Webdriver interface.

Timeouts interface has three abstract methods, which are :

implicitlyWaitsetScriptTimeoutpageLoadTimeout

There is no implementation present for these methods in the Timeouts interface; the browser classes(FirefoxDriver, ChromeDriver..) provides the implementations for these methods because the browser classes implement the Webdriver Interface.

Page Load Timeout in Selenium Webdriver

Page load timeout in selenium requests/set the time limit for a page to load, If the page is not loaded within the given time frame selenium throws TimeOutException.

We can set the page load timeout using the pageLoadTimeout method present in Browser classes(FirefoxDriver, ChromeDriver..)

driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS);

Page load timeout is useful when we perform a performance test, or when we test execution in IE.

Page Load timeout is applicable only to driver.get() and driver.navigate().to() methods in selenium

Setting Negative time limit makes the selenium to wait for the page load infinitely

// set page load time as infinite (by giving minus value) driver.manage().timeouts().pageLoadTimeout(-10, TimeUnit.SECONDS);Page load timeout is not applicable when the user clicks a link to open a page.

Complete program for Page load timeout

public class PageLoadTimeTest { public static void main(String[] args) { // set chrome driver exe path System.setProperty("webdriver.chrome.driver", "C:/~/chromedriver.exe"); WebDriver driver = new ChromeDriver(); driver.get("https://chercher.tech/"); // set the time of 30 seconds for page to complete the loading driver.manage().timeouts().pageLoadTimeout(30, TimeUnit.SECONDS); } }Set Script Load timeout

setScriptTimeout sets the time limit for the asynchronous script to finish execution, if the process is not completed before the time limit, selenium throws TimeOutException

The setScriptTimeout method affects only JavaScript code executed with executeAsyncScript and nothing else. In particular, executeScript is not affected by it.So why do you want to set a timeout for executeAsyncScript?

The default timeout for setScriptTimeout method is 0 (zero) if we do not set any time our executeAsyncScript method may fail because the JavaScript code may take more than zero seconds. So to avoid unnecessary failures, we have to set the setScriptTimeout.

Run a simple javascript: (Do not set setScriptTimeout ) - Now this shall execute without throwing any issue.

((JavascriptExecutor) driver).executeScript("alert('I am alert');");

Run a simple Async Script: ( Do not set setScriptTimeout) - This shall fail with error - "Timed out waiting for async script result after 0ms."

((JavascriptExecutor) driver).executeAsyncScript("document.getElementById('dummy')");

To resolve above issue add below-given setScriptTimeout

driver.manage().timeouts().setScriptTimeout(10, TimeUnit.SECONDS); ((JavascriptExecutor) driver).executeAsyncScript("document.getElementById('dummy')");Recommended ReadingsSelenium interview questionsXpath Interview QuestionsSelenium tricky interview questionsCore Java Interview Questions Set 1Arraylist in SeleniumNormalize space XPath in SeleniumThread Guard Class in SeleniumStale Element Eeference Exception in Selenium
