使用Selenium Webdriver测试sessionStorage

Question

我在编写基于Java的selenium-webdriver测试。我正在测试的应用程序在storageSession中设置了某些值，例如sessionStorage.setItem("demo", "test")，我怎么能在我的测试中检查并断言存储的变量demo的价值

发现了一个伟大的工具类https://gist.github.com/roydekleijn/5073579

import org.openqa.selenium.JavascriptExecutor; 
import org.openqa.selenium.WebDriver; 

public class LocalStorage { 
    private JavascriptExecutor js; 

    public LocalStorage(WebDriver webDriver) { 
    this.js = (JavascriptExecutor) webDriver; 
    } 

    public void removeItemFromLocalStorage(String item) { 
    js.executeScript(String.format(
     "window.localStorage.removeItem('%s');", item)); 
    } 

    public boolean isItemPresentInLocalStorage(String item) { 
    return !(js.executeScript(String.format(
     "return window.localStorage.getItem('%s');", item)) == null); 
    } 

    public String getItemFromLocalStorage(String key) { 
    return (String) js.executeScript(String.format(
     "return window.localStorage.getItem('%s');", key)); 
    } 

    public String getKeyFromLocalStorage(int key) { 
    return (String) js.executeScript(String.format(
     "return window.localStorage.key('%s');", key)); 
    } 

    public Long getLocalStorageLength() { 
    return (Long) js.executeScript("return window.localStorage.length;"); 
    } 

    public void setItemInLocalStorage(String item, String value) { 
    js.executeScript(String.format(
     "window.localStorage.setItem('%s','%s');", item, value)); 
    } 

    public void clearLocalStorage() { 
    js.executeScript(String.format("window.localStorage.clear();")); 
    } 
}
