Question

我正在尝试自动化并朗读一个简单的注册表单，但我收到错误说＆＃34;失败：Fn不是函数＆＃34;。以下是我的代码

    describe('Locator testing by model', function(){

    it('automate user register form', function(){
        browser.get('http://www.way2automation.com/angularjs-protractor/registeration/#/login');
        element(by.model('Auth.user.name')).sendKeys('angular');
        element(by.model('Auth.user.password')).sendKeys('password');
        element(by.model('model[options.key]')).sendKeys('zafaque');
        element(by.buttonText('Login')).click();
        browser.wait(3000);
    });
});

下面是错误明细

Answer 1

您错误地使用了browser.wait()。请参阅官方文档以了解正确使用情况here

browser.wait（）接受以下命令中的params

第一个参数是一个可以是函数或a的条件 webdriver.promise.Promise或预期条件第二个参数是超时

但是你将超时作为第一个参数传递。如果等待无条件等待 - 请使用browser.sleep(3000)

得到错误＆＃34;失败：Fn不是一个函数＆＃34;当尝试自动化e2e登录页面时
