尝试为登录页面自动化 e2e 时出现错误 "Failed: Fn is not a function"

Question

我正在尝试自动化并朗读一个简单的注册表单，但我收到错误提示 "Failed: Fn is not a function"。下面是我的代码

    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);
    });
});

下面是错误详情

Answer 1

您使用 browser.wait() 不正确。正确使用请参考官方文档here

browser.wait() 按以下顺序接受参数

first argument is a condition which can be a function or a webdriver.promise.Promise or a Expected Condition Second Argument is the timeout

但是您将超时作为第一个参数传递。如果你只是等待无条件等待 - 只需使用 browser.sleep(3000)
