Javascript 测试非角度js网站时，browser.wait在量角器中不工作

我正在用量角器测试一个无角度的js网站

我的测试用例运行成功，但我想删除sleep语句，并向测试用例中添加wait或Expected条件

我的代码如下：

var co = require('co');
var path = require('path');

describe("TEST ", function () {

    it("test", co.wrap(function* () {
         browser.ignoreSynchronization = true;
        var EC = protractor.ExpectedConditions;
        yield browser.get('URL');
        browser.wait(function () {
            return browser.driver.isElementPresent(by.css(a[href = "#login"]));
        }, 30000);
        var elmOK = browser.driver.findElement(by.css('a[href="#login"]'));
        yield elmOK.click();
        expect(browser.getCurrentUrl()).toContain("login");
        yield browser.switchTo().frame('here-account-sdk').then(function () {
            browser.driver.findElement(by.id('sign-in-email')).sendKeys("supplier_portal@yahoo.com");
            browser.driver.findElement(by.id('sign-in-password-encrypted')).sendKeys("voting123");
            browser.driver.findElement(by.xpath(' //*[@id="sign-in-form"]/div[2]/div[6]/form/fieldset[3]/button')).click();

        });
        //  browser.sleep(5000);
        var elmOK = browser.driver.findElement(by.xpath('//*[@id="lnav"]/li[3]/a'));
        yield elmOK.click();
        //  browser.sleep(1500);
        browser.driver.findElement(by.xpath('//*[@id="administration"]/div/div[1]/select/option[2]')).click();
        //    browser.sleep(5000);

        browser.driver.findElement(by.xpath('//*[@id="administration"]/div/div[2]/table/tbody/tr[1]/td[10]/span')).click();
        //     browser.sleep(5000);

        browser.driver.findElement(by.xpath('//*[@id="content"]/div/div[2]/div/div/div/div[3]/button[1]')).click();
        //    browser.sleep(5000);
    }));




});

当我尝试运行我的测试时，我得到以下错误。我不知道怎么修理它

请帮忙？

这是：

 yield browser.switchTo().frame('here-account-sdk').then(function () {
        browser.driver.findElement(by.id('sign-in-email')).sendKeys("supplier_portal@yahoo.com");
        browser.driver.findElement(by.id('sign-in-password-encrypted')).sendKeys("voting123");
        browser.driver.findElement(by.xpath(' //*[@id="sign-in-form"]/div[2]/div[6]/form/fieldset[3]/button')).click();

    });

唯一一个与角度无关的部分？如果是，请尝试添加

browser.switchTo（）.defaultContent（）

before

var elmOK=browser.driver.findElement（by.xpath（'/*[@id=“lnav”]/li[3]/a'）
您是否试图使用参数“\u failures”读取conf.js文件中的规范结果？请看我的回答Hi@diegovmellet我的输入网站是非角度js
