如何使用量角器js測試無角網站？

Question

我一直在尋找所有的互聯網，但似乎沒有任何可靠的資源或例子測量無角度的網站與量角器JS。

目前，我的conf文件看起來像這樣

exports.config = { 
    seleniumServerJar: 'webdriver/selenium-server-standalone-2.48.2.jar', 
    specs: [ 
    'wikipedia-test-spec.js' 
    ], 
    chromeDriver : 'webdriver/chromedriver.exe', 

    multiCapabilities: [ 
    { 
     'browserName': 'chrome' 
    } 
    ], 

    }; 

我的維基百科測試spec.js看起來像這樣

describe("Tests a wikipedia page", function(){ 
    it('Should check if table exists', function(){ 
      browser.get('https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_population'); 
      var table = browser.driver.findElement(by.name('table')); 
      expect(table.isPresent()).toBeTruthy(); 
    }); 

}); 

當我運行protractor conf.js，我得到一個錯誤類型undefined is not a function和我的規範失敗了。

UPDATE：錯誤

Answer 1

isPresent() function的

整個堆棧跟蹤可在ElementFinder實例，這是element()調用的結果。您可能需要在這裏使用driver.isElementPresent()：

var table = browser.driver.findElement(by.name('table')); 
expect(table.isPresent()).toBeTruthy(); 

有：

var table = browser.driver.findElement(by.name('table')); 
expect(browser.driver.isElementPresent(table)).toBeTruthy(); 

或者，你也可以嘗試用element()：

var table = element(by.name('table')); 
expect(table.isPresent()).toBeTruthy();

請注意，您還需要將與AngularJS的同步關閉：

browser.ignoreSynchronization = true; 

另見：

• In protractor, browser.isElementPresent vs element.isPresent vs element.isElementPresent
