如何在appium中进行编辑文本错误消息验证

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.remote.MobileCapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;

public class AppiumTest {
    public static void main(String[] args) {
        // 设置Desired Capabilities
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
        caps.setCapability(MobileCapabilityType.DEVICE_NAME, "deviceName");
        caps.setCapability(MobileCapabilityType.APP, "path/to/app.apk");

        // 初始化AppiumDriver
        AppiumDriver<MobileElement> driver = new AndroidDriver<>("http://localhost:4723/wd/hub", caps);

        // 执行测试步骤
        // 输入文本
        MobileElement textField = driver.findElementById("com.example.app:id/textField");
        textField.sendKeys("Hello Appium");

        // 验证错误消息
        MobileElement errorMessage = driver.findElementById("com.example.app:id/errorMessage");
        String actualErrorMessage = errorMessage.getText();
        String expectedErrorMessage = "Invalid input";
        if (actualErrorMessage.equals(expectedErrorMessage)) {
            System.out.println("Error message is correct");
        } else {
            System.out.println("Error message is incorrect");
        }

        // 关闭驱动
        driver.quit();
    }
}
