WebDriver application example (java) - manipulation of HTML5 storage objects

        The purpose of this instance is to be able to read HTML5's localStorage and sessionStorage, and delete the stored content.

        The specific example code is as follows:

package cn.om.TestHTML5;

import org.testng.annotations.Test;
import org.testng.annotations.BeforeMethod;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.AfterMethod;

public class TestHtml5Storage {

	WebDriver driver;
	String localStoreUrl;
	String sessionStoreUrl;

	@Test
	public void testHtml5localStorage() {
		driver.get(localStoreUrl);
		JavascriptExecutor jsExecutor = (JavascriptExecutor) driver;
		// Call the JavaScript statement "return
		// localStorage.lastname" gets the stored value of "lastname" stored in localStorage
		String lastname = (String) jsExecutor.executeScript("return localStorage.lastname;");
		// Assert if the retrieved stored value is "Smith"
		Assert.assertEquals("Gates", lastname);
		// Call the JavaScript statement "localStorage.clear()" to clear all variable values ​​stored in localStorage
		jsExecutor.executeScript("localStorage.clear();");
	}

	@Test
	public void testHtml5sessionStorage() {
		driver.get(sessionStoreUrl);
		JavascriptExecutor jsExecutor = (JavascriptExecutor) driver;
		// Call the JavaScript statement "return
		// localStorage.lastname" gets the stored value of "lastname" stored in localStorage
		jsExecutor.executeScript("sessionStorage.setItem('lastname','Gates');");
		String lastname = (String) jsExecutor.executeScript("return sessionStorage.lastname;");
		// Assert if the retrieved stored value is "Smith"
		Assert.assertEquals("Gates", lastname);
		//Clear the "lastname" item stored in sessionStorage
		jsExecutor.executeScript("sessionStorage.removeItem('lastname');");
		// Call the JavaScript statement "localStorage.clear()" to clear all variable values ​​stored in localStorage
		jsExecutor.executeScript("sessionStorage.clear();");
	}

	@BeforeMethod
	public void beforeMethod() {
		System.setProperty("webdriver.firefox.bin", "D:/Mozilla Firefox/firefox.exe");
		driver = new FirefoxDriver();
		localStoreUrl = "http://www.w3school.com.cn/tiy/t.asp?f=html5_webstorage_local";
		sessionStoreUrl = "http://www.w3school.com.cn/tiy/t.asp?f=html5_webstorage_session";
	}

	@AfterMethod
	public void afterMethod() {
		driver.quit();
	}

}
