Counting number of successes and failures in TESTNG and Java (selenium)

I have a little JAVA program that login into a website

package testingProgram;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.Test;

public class testingProgram {

	@Test
	public void helloWorldTest() {
		System.out.println("Hello World!");
		
		System.setProperty("webdriver.chrome.driver","C:\\Users\\Steve\\Desktop\\chromedriver.exe");

		WebDriver driver = new ChromeDriver(); 

		driver.get("https://website234/backend/");
		driver.findElement(By.id("username")).sendKeys("admin");
		driver.findElement(By.id("login")).sendKeys("admin");
		driver.close();
		
		WebDriver driver2 = new ChromeDriver(); 
		driver2.get("https://website234/backend/");
		driver2.findElement(By.id("username")).sendKeys("admin");
		driver2.findElement(By.id("login")).sendKeys("admin2");
	}
}

> Note: in my example the correct login is:
>
> username = admin and password = admin

It opens 2 chrome sessions and tries to login by using different passwords.

If it fails login it throws and error message like this:

My testng test shows this:

But i want the output to tell me how many tests passed and in my case only one username and password worked correctly.

Expected result:

    Default test
    Tests run: 1, Failures: 0, Skips: 0
===============================================


===============================================
Default suite
Total tests run: 1, Passes: 1 (username = admin, password = admin), Failures: 1 (username = admin, password = admin2), Skips: 0

because i was able to login by using username = admin and password = admin but it wont be able to login using username = admin and password = admin2

How can i achieve something like that?

Something wrong:

1. Even you have 2 initialize driver, your script recognized as one test only.
2. You have to give a condition how to submit a successful login.
3. For username and password, looks like you want the logs, but it doesn't look like it's set at all.

Approach:

1. Create 2 @Test annotation for each test.
2. Mark what a successful login looks like., mostly with welcome home
3. Logs set, with : import org.testng.Reporter;

@Test
public void helloWorldTest1() {
....
//logs set
String username = "admin";
String password = "admin";
Reporter.log("username = " +username, true);
Reporter.log("password = " +password, true);
driver.get("https://website234/backend/");
driver.findElement(By.id("username")).sendKeys(username);
driver.findElement(By.id("login")).sendKeys(password);
//here, i think need to submit login button
buttonLogin.click();
//here, find a welcome home locator maybe
WebElement welcomeHome = driver.findElement(By.name("a locator"));
}
@Test
public void helloWorldTest2() {
....
//logs set
String username = "admin";
String password = "admin2";
Reporter.log("username = " +username, true);
Reporter.log("password = " +password, true);
driver.get("https://website234/backend/");
driver.findElement(By.id("username")).sendKeys(username);
driver.findElement(By.id("login")).sendKeys(password);
//here, i think need to submit login button
buttonLogin.click();
//here, find a welcome home locator maybe
WebElement welcomeHome = driver.findElement(By.name("a locator"));
}

Console output:

Note : You can see logs in default report too emailable-report.html:

Btw there is way to achive this still with one @Test, you can learn about @DataProvider and invocationcount to repeat this test with various parameter.
