我通過等待DOM改變作爲Ajax調用的結果做到這一點。我做了DocumentElement的子類,稱其AsyncDocumentElement並重寫的findAll方法:
public function findAll($selector, $locator, $waitms=5000)
{
$xpath = $this->getSession()->getSelectorsHandler()->selectorToXpath($selector, $locator);
// add parent xpath before element selector
if (0 === strpos($xpath, '/')) {
$xpath = $this->getXpath().$xpath;
} else {
$xpath = $this->getXpath().'/'.$xpath;
}
$page = $this->getSession()->getPage();
// my code to wait until the xpath expression provides an element
if ($waitms && !($this->getSession()->getDriver() instanceof \Behat\Symfony2Extension\Driver\KernelDriver)) {
$templ = 'document.evaluate("%s", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null).snapshotLength > 0;';
$waitJs = sprintf($templ, $xpath);
$this->getSession()->wait($waitms, $waitJs);
}
return $this->getSession()->getDriver()->find($xpath);
}
然後在\貝哈特\水貂\會議,我改變了構造函數使用類。
public function __construct(DriverInterface $driver, SelectorsHandler $selectorsHandler = null)
{
$driver->setSession($this);
if (null === $selectorsHandler) {
$selectorsHandler = new SelectorsHandler();
}
$this->driver = $driver;
$this->page = new AsyncDocumentElement($this);
$this->selectorsHandler = $selectorsHandler;
}
一旦我這樣做了,我發現我的AngularJS測試正在工作。到目前爲止,我只在Firefox中測試過。
