Getting error message on webpage but test cases get passed -using testng with selenium

Question

Driver class:

package com.deere.gmsr;

import java.util.Properties;
import java.util.concurrent.TimeUnit;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class Driver {

    public static WebDriver driver;
    public static WebDriver openBrowser(String browserName, String url) throws InterruptedException {

        if(browserName.equals("chrome")) {

            System.setProperty("webdriver.chrome.driver", "D:\\chromedriver\\chromedriver.exe");
            driver=new ChromeDriver();
            driver.manage().window().maximize();
            driver.get(url);
            driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
            return driver;

        }else
        if(browserName.equals("IE")) {
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver\\chromedriver.exe");
        driver=new ChromeDriver();
        driver.manage().window().maximize();
    //  driver.get(url);
        Thread.sleep(5000); 
        return driver;


    }else
    if(browserName.equals("Firefox")) {
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver\\chromedriver.exe");
        driver=new ChromeDriver();
        driver.manage().window().maximize();
    //  driver.get(url);
        Thread.sleep(5000); 
        return driver;
    }
        return driver;

}


    public static WebDriver getDriver(){
        try{
            if(driver == null) {

            PropertiesFileReader obj=new PropertiesFileReader(); 
            Properties properties=obj.getproperty();
            openBrowser(properties.getProperty("browserName"), properties.getProperty("URL"));
        }
        }catch(Exception e) {
            e.printStackTrace();
        }
        return driver;
    }

    public void quitDriver() {
        driver.close();
        driver.quit();
    }

}

Properties :

package com.deere.gmsr;

import java.io.FileInputStream;
import java.io.IOException;
import java.util.Properties;

public class PropertiesFileReader {

    public Properties getproperty() throws IOException {
        FileInputStream inputstream=null;
        Properties properties=new Properties();
        try {
            properties.load(new FileInputStream("Configuration/config.properties"));
        }catch(Exception e) {
            System.out.println("Exception " +e);
        }

            return properties;
        }


}

Loginpage:

package com.deere.gmsr.page;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.How;
import org.openqa.selenium.support.PageFactory;

public class LoginPage {

    //  WebDriver driver;

    public LoginPage(WebDriver driver) {
    //  this.driver=driver;
        PageFactory.initElements(driver, this);

    }

    @FindBy(how=How.ID,using="username")
    public WebElement usernametexbox;

    @FindBy(how=How.ID,using="-password")
    public WebElement passwordtextbox;

    @FindBy(how=How.ID,using="signin-")
    public WebElement signin;

/*  @FindBy(how=How.XPATH,using="//button[@class='btn btn-primary']")
    public WebElement acceptbutton; */

   public void enter_username(String username) {

    usernametexbox.clear();
    usernametexbox.sendKeys(username);
    usernametexbox.getText();
    }

    public void enter_password(String password) {

        passwordtextbox.clear();
        passwordtextbox.sendKeys(password);
    }

    public void clickToSigninbutton() {
        signin.click();
    }

/*  public void clickToAcceptbutton() {


    acceptbutton.click();

    } */

public void fill_LoginDetails() {

    enter_username("ggggg");
    enter_password("hhhhh");



    }


}  

Logintestcase:

package com.deere.gmsr.testcase;

import org.openqa.selenium.WebDriver;
import org.testng.annotations.BeforeSuite;
import org.testng.annotations.Test;

import com.deere.gmsr.Driver;
import com.deere.gmsr.page.LoginPage;

    public static WebDriver driver;


    public LoginPage loginpage=new LoginPage(Driver.getDriver());


@Test
public void enter_LoginDetails() {

    loginpage.fill_LoginDetails();

/*   Properties properties=obj.getproperty();
 driver=BrowserUtility.openBrowser(properties.getProperty("browserName"),properties.getProperty("URL")); */

}


@Test
public void click_on_sign_in_button() {

    loginpage.clickToSigninbutton();

    System.out.println("Sign-In successfully");

}

}  

testng xml:

<suite name="GMSR">
    <test name="LoginTest">
        <classes>
            <class name="com.deere.gmsr.testcase.LoginTestcase" />
        </classes>
    </test>
</suite>

Answer 1

Test case does not fail because it does not include any assertions. As mentioned by @Upkar Singh in the comment - your login test data is not valid, therefore page is showing some kind of error saying that login did not succeed.

If you want the test case to fail, you need to assert that some condition is met (i.e. that some kind of homepage is shown). I do not know how your page looks like but it will be something like this:

Assert.assertTrue(some_condition_met);

The condition can be something like:

driver.getTitle().equals(PAGE_TITLE);

But that is specific to webpage you are testing.
