Selenium driver - wait on page reload

Question

Is there a way, how to wait on page reload? For example, when I'm on page localhost:9000/web and I instruct the webdriver again to navigate to the localhost:9000/web. I don't want or can't indicate the reloading by waiting on some elements.

Answer 1

In Selenium WebDriver we can implement waitForPageToLoad using the following code snippet :

public void waitForPageToLoad(WebDriver driver) {
    ExpectedCondition < Boolean > pageLoad = new
    ExpectedCondition < Boolean > () {
        public Boolean apply(WebDriver driver) {
            return ((JavascriptExecutor) driver).executeScript("return document.readyState").equals("complete");
        }
    };

    Wait < WebDriver > wait = new WebDriverWait(driver, 60);
    try {
        wait.until(pageLoad);
    } catch (Throwable pageLoadWaitError) {
        assertFalse("Timeout during page load", true);
    }
}

Answer 2

This is old but I also wanted a solution for this, and stumbled onto this question.

Thanks to the answers posted, I created my own solution by combining the expected condition of staleness of the html and the waitForPageToLoad function from @mfsi_sitamj post.

Something like this:

@CacheLookup
@FindBy(tagName = "html")
private WebElement __document;

public void waitForReload() {
    Wait<WebDriver> wait = new WebDriverWait(driver, 10);
    wait.until(ExpectedConditions.stalenessOf(this.__document));
    wait.until((ExpectedCondition<Boolean>) wd ->
        ((JavascriptExecutor) wd).executeScript("return document.readyState").equals("complete"));
}
