當嘗試自動化登錄頁面的e2e時出現錯誤「失敗：Fn不是函數」

Question

我試圖自動化和朗姆酒一個簡單的註冊表單，但我得到錯誤說「失敗：Fn不是函數」。下面是我的代碼

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); 
    }); 
}); 

以下是錯誤詳細

Answer 1

您正在使用browser.wait()不正確。參閱官方文檔爲正確用法here

browser.wait（）接受在下面的順序PARAMS

第一個參數是它可以是一個函數或 webdriver.promise.Promise或預期的條件條件第二個參數是 超時

但是您傳遞超時作爲第一個參數。 Incase你只是等待無條件的等待 - 只需使用browser.sleep(3000)
