ログインページのe2eを自動化しようとすると「失敗：Fnは関数ではありません」

Question

単純な登録フォームを自動化してラムをしようとしていますが、「失敗：Fnは関数ではありません。以下は、私のコードの下

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); 
    }); 
}); 

はあなたが間違ってbrowser.wait()を使用しているエラーの詳細

最初の引数が関数または webdriver.promise.Promise又は期待できる条件である以下の順序でのparamsを受け入れる）（正しい使用方法についてhere

browser.waitを公式ドキュメントを参照条件2番目の引数は タイムアウトです

しかし、最初の引数としてタイムアウトを渡しています。あなたはちょうど無条件の待ちを待っている - ちょうど使用するbrowser.sleep(3000)
