Accessing localStorage in Protractor test for AngularJS application
提问by Zack Argyle
I am writing some tests to verify that input data is being stored in local storage correctly, how can I access localStorage from within the protractor test?
我正在编写一些测试来验证输入数据是否正确存储在本地存储中，如何从量角器测试中访问 localStorage？
...
describe('vgPersist', function() {
it('Should save input data in local storage until form submitted', function() {
// Prepare Object and Open browser
var addOns = new AddOns();
addOns.get();
-> Clear localStorage
-> Get from localStorage
How do you use executeScript? And could I get data from an executeScript?
你如何使用executeScript？我可以从 executeScript 获取数据吗？

To get an item from local storageuse window.localStorage.getItem()through executeScript():
为了获得从本地存储中的项目使用window.localStorage.getItem()过executeScript()：
var value = browser.executeScript("return window.localStorage.getItem('key');");
expect(value).toEqual(expectedValue);
To clear local storagecall clear():
要清除本地存储的呼叫clear()：
browser.executeScript("window.localStorage.clear();");
We can also have this helper object/wrapper around the local storage for convenience:
为方便起见，我们还可以在本地存储周围使用此辅助对象/包装器：
"use strict";
var LocalStorage = function () {
this.getValue = function (key) {
return browser.executeScript("return window.localStorage.getItem('" + key + "');");
};
this.get = function () {
browser.executeScript("return window.localStorage;");
};
this.clear = function () {
browser.executeScript("return window.localStorage.clear();");
};
};
module.exports = new LocalStorage();
