如何呼叫at

剛剛只有在Page中定義了at靜態屬性，但不代表你在執行to GebHomePage2時，就會一併檢查at，需要另外寫at GebHomePage2才行。

import geb.Browser

Browser.drive {
    to GebHomePage2
    at GebHomePage2
}

但另一種情況，它就會預設執行at檢查。

$('a.home2').click(GebHomePage2)

拋出異常

當條件不符合，at內所以定義時，就會跳出類似於下方的失敗訊息。

import geb.*

class GebHomePage2 extends Page {
    static url = "http://www.gebish.org/"
    static at = { $('h1').size() == 6 }
}





Caught: Assertion failed:

$('h1').size() == 6
|       |      |
|       5      false
