How to check mandatory field whether it is empty or not in Selenium WebDriver using Java?
提问by Nasrin Naher
I am working on "add new user form" . In this form, there are several mandatory fields. Form will not be submitted when any mandatory field is empty and it will show a validation message like : "Value is required and can't be empty". How can I check/automate the form whether field is empty or not?
我正在处理“添加新用户表单”。在此表单中，有几个必填字段。当任何必填字段为空时，将不会提交表单，它将显示一条验证消息，例如：“值是必需的，不能为空”。如何检查/自动化表单字段是否为空？

Way 1: First, write the following method:
方式一：首先编写如下方法：
private boolean isTextPresent(String text){
try{
boolean b = driver.getPageSource().contains(text);
return b;
}
catch(Exception e){
return false;
}
}
Now do assertion whether the expected message is present or not on the page by calling the above method:
现在通过调用上述方法断言页面上是否存在预期的消息：
assertTrue(isTextPresent("Value is required and can't be empty"), "Msg is absent/wrong/misspelled");
Way 2: Another way is as follow:
方式二：另一种方式如下：
import java.util.regex.Pattern;
import java.util.concurrent.TimeUnit;
import org.junit.*;
import static org.junit.Assert.*;
import static org.hamcrest.CoreMatchers.*;
import org.openqa.selenium.*;
private StringBuffer verificationErrors = new StringBuffer();
try {
assertTrue(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\s\S]*Value is required and can't be empty[\s\S]*$"));
} catch (Error e) {
verificationErrors.append(e.toString());
}
}

You can use assertfor checking the mandatory field alert is appearing or not, with try-catch
您可以使用asserttry-catch 检查必填字段警报是否出现
try {
assertEquals("Value is required and can't be empty", driver.findElement(By.xpath("XPATH_OF_LABLE")).getText());
} catch (Error e) {
//code for the case when the texts are not same
verificationErrors.append(e.toString());
}
the example is using xpath, but you can use any other locator method for this.
该示例使用的是 xpath，但您可以为此使用任何其他定位器方法。

Use SoftAssertto validate all of the mandatory fields in a form by a single @Testannotation. Even if any of the assertions fail, it will execute the next line and gives us the all exception caught in @Testwhen we do assertAll()at the end.
用于SoftAssert通过单个@Test注释验证表单中的所有必填字段。即使任何断言失败，将执行下一行，使我们陷入了所有的异常@Test，当我们做assertAll()结尾。
driver.findElement(by.id("submit")).click();
SoftAssert softAssert = new SoftAssert();
softAssert.assertEquals(firstname.getText(), "First Name is required");
softAssert.assertEquals(lastname.getText(), "Last Name is required");
softAssert.assertEquals(email.getText(), "Email Address is required");
softAssert.assertAll();
