selenium webdriver 学习总结-Selenium 控制测试流_补充显示等待（五）

补充显示等待，深入使用FluentWait 与 Predicate、Funciton

wait.pollingEvery(50,TimeUnit.MILLISECONDS).withTimeout(10,TimeUnit.SECONDS);

@Override

public boolean apply(WebDriver driver) {

try{

return driver.findElement(By.id("hello")).isDisplayed();

}

@Test

public void testFunction(){

wait.withTimeout(10,TimeUnit.SECONDS).pollingEvery(10,TimeUnit.MILLISECONDS).ignoring(NoSuchElementException.class);

wait.until(new Function(){

@Override

public WebElement apply(WebDriver driver) {

WebElement element = driver.findElement(By.id("hello"));

return element;

}

});

}
