如何验证字段没有值（null）？

Question

如何使用Selenium Web Driver检查某个字段是否没有值（null）？

这是我到目前为止所做的：

WebDriverWait wait5 = new WebDriverWait(driver, 5);
wait5.until(ExpectedConditions.elementToBeClickable(By.name("chargeId")));

Answer 1

WebDriverWait wait5 = new WebDriverWait(driver, 5);
WebElement charge = wait5.until(ExpectedConditions.elementToBeClickable(By.name("chargeId")));
boolean noChargeIdPresent = charge.getText().isEmpty();

这将告诉您该字段是否为空。

Answer 2

WebDriverWait wait5 = new WebDriverWait(driver, 5);
wait5.until(ExpectedConditions.elementToBeClickable(By.name("chargeId")));
if(wait5.findElement(By.name("chargeId")).getText().length() == 0) {
      // =========== DO WHAT YOU WANT IF EMPTY============
}
else {
     //======== DO WHEN NOT EMPTY==================
}
