Question

我试图期望localStorage值，我认为可以从window对象访问。但每当我尝试运行以下代码时：

browser.executeScript(function () {
       console.log('window.localStorage:'+window.localStorage);
      });

我收到以下错误： - Java Process打开JVM执行，控制台显示：

Answer 1

要从本地存储中获取项目，请使用window.localStorage.getItem()到executeScript()：

var value = browser.executeScript("return window.localStorage.getItem('key');");
expect(value).toEqual(expectedValue);

为方便起见，我们还可以在本地存储周围安装此辅助对象/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();

Answer 2

问题是您尝试使用代码打印storage类型的对象。

   console.log('window.localStorage:'+window.localStorage);

相反，您可以使用的是Properties或Methods，其中包含要显示相应存储类型的键。 e.g。

   console.log('window.localStorage.font:' + window.localStorage.getItem('font'));
