我以这种方式使用它:

function LoginPage() {
  this.get = function() {
        browser.get('#/Login');
        browser.executeScript('window.localStorage.clear();');
        browser.executeScript('window.sessionStorage.clear();');
        browser.driver.manage().deleteAllCookies(); 
    }
}

module.exports = new LoginPage;

然后我在我的任何测试脚本中都使用此功能，该脚本每次都会清除cookie，会话/本地存储.

then I use this function in any of my test script which every time clears out cookies, session/local storage.

var loginPage = require('.././LoginPage'); 
loginPage.get();
