In this WebDriver tutorial we take a look at how to wait for a page to complete loading before doing other actions. Two examples in Java on wait for page to load in WebDriver.
Wait For Page To Load – Method #1
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | import org.openqa.selenium.JavascriptExecutor; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedCondition; import org.openqa.selenium.support.ui.WebDriverWait; import org.testng.Assert; public class Tutorials { WebDriver driver = new FirefoxDriver(); public void waitForPageLoaded() { ExpectedCondition<Boolean> expectation = new ExpectedCondition<Boolean>() { public Boolean apply(WebDriver driver) { return ((JavascriptExecutor) driver).executeScript("return document.readyState").toString().equals("complete"); } }; try { Thread.sleep(1000); WebDriverWait wait = new WebDriverWait(driver, 30); wait.until(expectation); } catch (Throwable error) { Assert.fail("Timeout waiting for Page Load Request to complete."); } } } |
Wait For Page To Load Method #2
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | import org.openqa.selenium.JavascriptExecutor; import org.openqa.selenium.WebDriver; import org.openqa.selenium.support.ui.ExpectedCondition; import org.openqa.selenium.support.ui.WebDriverWait; public class Tutorials { public void waitForLoad(WebDriver driver) { ExpectedCondition<Boolean> pageLoadCondition = new ExpectedCondition<Boolean>() { public Boolean apply(WebDriver driver) { return ((JavascriptExecutor)driver).executeScript("return document.readyState").equals("complete"); } }; WebDriverWait wait = new WebDriverWait(driver, 30); wait.until(pageLoadCondition); } } |

Why do we need to write code to wait for ‘page load’?
As per my knowledge WebDriver starts execution only after page loaded completely.
Pls post the scenarios, where it’ll be useful.
