Selenium Java – How to Clear Browser Cache in Selenium Test

browser-cachejavaseleniumselenium-webdriver

I am running my Selenium tests with WebDriver. I am repeating the tests with some loop so now I want to Clear the cache before starting new test in JAVA.

@Test
public void ffAndIe() throws InterruptedException {
    int i = 0;
    while(i < 5000){

        driver.get("http://dit-map.appspot.com/");
        Thread.sleep(15000);
        driver.get("http://dit- map.appspot.com/#home:zoom=7&lat=37.04&lng=25.05&display=weather");
        Thread.sleep(15000);
        driver.get("http://dit-map.appspot.com/#home:zoom=9&lat=37.55&lng=23.83&display=weather,wind");
        Thread.sleep(10000);
        driver.get("http://dit-map.appspot.com/#home:zoom=9&lat=37.84&lng=23.22&display=weather,wind,cloud");
        Thread.sleep(10000);
        driver.get("http://dit-map.appspot.com/?lang=en#home:zoom=10&lat=38.13&lng=22.59&display=weather,wind,meteogram");
        Thread.sleep(10000);
        i++;
    }
}

with in this while loop the first thing I want to do is to CLEAR my CACHE (IE, MOZILLA & CHROME)

any idea how can I achieve this?

Thanks

Currently, there is no way to clear the cache through the web driver API. However, if you can start a new instance of the browser each time, the cache should be cleared in FF and Chrome because a new profile is created on each launch.

The comments for issue #40 (Clear cache) in the Selenium issue tracker list two potential solutions to your problem if creating a new browser instance isn't possible:

Clear the IE cache from the command line
Disable the FF cache using a custom profile

Selenium – How to Clear Chrome Cache

You are using here

driver.findElement(By.xpath("//*[@id='clearBrowsingDataConfirm']")).click();

Unfortunately, this won’t work because the Chrome settings page uses Polymer and WebComponents, need to use query selector using the /deep/ combinator, so selector in this case is * /deep/ #clearBrowsingDataConfirm.

Here is workaround to your problem...you can achieve the same using either one of the following...

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

public class ClearChromeCache {

    WebDriver driver;

    /*This will clear cache*/
    @Test
    public void clearCache() throws InterruptedException {
        System.setProperty("webdriver.chrome.driver","C://WebDrivers/chromedriver.exe");
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("disable-infobars");
        chromeOptions.addArguments("start-maximized");
        driver = new ChromeDriver(chromeOptions);
        driver.get("chrome://settings/clearBrowserData");
        Thread.sleep(5000);
        driver.switchTo().activeElement();
        driver.findElement(By.cssSelector("* /deep/ #clearBrowsingDataConfirm")).click();
        Thread.sleep(5000);
    }

    /*This will launch browser with cache disabled*/
    @Test
    public void launchWithoutCache() throws InterruptedException {
        System.setProperty("webdriver.chrome.driver","C://WebDrivers/chromedriver.exe");
        DesiredCapabilities cap = DesiredCapabilities.chrome();
        cap.setCapability("applicationCacheEnabled", false);
        driver = new ChromeDriver(cap);
    }
}
