推荐答案

Selenium API不直接支持约束验证。但是，您可以使用一段JavaScript（Java）轻松获取状态和消息：

The Selenium API doesn't support directly the constraint validation. However, you could easily get the state and the message with a piece of JavaScript (Java):

JavascriptExecutor js = (JavascriptExecutor)driver;

WebElement field = driver.findElement(By.name("email"));
Boolean is_valid = (Boolean)js.executeScript("return arguments[0].checkValidity();", field);
String message = (String)js.executeScript("return arguments[0].validationMessage;", field);

请注意，也可以使用 getAttribute 获取 validationMessage ，即使它是属性：

Note that it is also possible to use getAttribute to get the validationMessage even though it is a property:

String message = driver.findElement(By.name("email")).getAttribute("validationMessage");
