Selenium script fails with TestNG annotation

Question

Steps:
1. In eclipse I've created a new project named 'ForSe'.

Under 'src' folder → 'default package' I created a class named
Login.java
.

My code inside this class is like this:

public class Login_Valid {      

    public static void main(String[] args) throws InterruptedException {                

        System.setProperty("webdriver.chrome.driver","*my path*");

        WebDriver driver = new ChromeDriver();

        driver.manage().window().maximize();

        driver.get("*URL of prject ForSe*");

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

        driver.findElement(By.xpath("//*@id='email_address']")).sendKeys("*email address*");

        driver.findElement(By.xpath("//*[@id='password']")).sendKeys("*Password*");

        driver.findElement(By.xpath("//*[@id='login-form']/div[4]/button")).click();

    }

}

The scripts run very well when I run with
run as java application
.
But when I use the same script with TestNG, it skips/fails my test.

Steps taken to create TestNG script is as follows:

Installed TestNG and under same
src
creates a new package named
ForSe_TestCases.java

My TestNG scripts is as follows:

public class ForSe_TestCases 

{

    WebDriver driver;

    String url = "*project's URL*";



    @Test (priority = 0)

    public void IO_login(WebDriver driver) 

    {



        //ForSe test environment URL

        driver.navigate().to(url);



        //this is official email address of IO

        driver.findElement(By.xpath("//*[@id='email_address']")).sendKeys("*email address*");



        //this is password

        driver.findElement(By.xpath("//*[@id='password']")).sendKeys("*Password*");



        //click on submit button to login

        driver.findElement(By.xpath("//*[@id='login-form']/div[4]/button")).click();

        System.out.println("Login button pressed");

    }



    @BeforeTest

    public void setup() 

    {

        // Set property for Chrome

        System.setProperty("webdriver.chrome.driver","*my path*");

        WebDriver driver = new ChromeDriver();



        //apply implicit wait

        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);



        //maximize window

        driver.manage().window().maximize();

    }

}

I'm unable to understand at which step I'm going wrong. This the error message I get on running my test by

Run as TestNG

    [Utils] [ERROR] [Error] org.testng.TestNGException:

    Cannot inject @Test annotated Method [IO_login] with [interface org.openqa.selenium.WebDriver].

Answer 1

These can be a few of the issues:

"my path" is not a valid variable name. Change it to "my_path".
Define a String my_path = "C:\\Utility\\BrowserDrivers\\chromedriver.exe"; as a global variable.
Check the variable when you provide System.setProperty("webdriver.chrome.driver","my_path");
Don't use driver.manage().window().maximize(); instead handle it with Options Class.
WebDriver driver is defined globally at Class level, you don't have to pass it as an argument in IO_login()

Check this code:

public class TestAnyURL_TestNG { WebDriver driver; String url = "http://google.com"; String my_path = "C:\Utility\BrowserDrivers\chromedriver.exe";

@Test (priority = 0)
public void IO_login() 
{

    //ForSe test environment URL
    driver.navigate().to(url);

    //this is official email address of IO
    driver.findElement(By.xpath("//*[@id='email_address']")).sendKeys("*email address*");

    //this is password
    driver.findElement(By.xpath("//*[@id='password']")).sendKeys("*Password*");

    //click on submit button to login
    driver.findElement(By.xpath("//*[@id='login-form']/div[4]/button")).click();
    System.out.println("Login button pressed");
}

@BeforeTest
public void setup() 
{
    System.setProperty("webdriver.chrome.driver", my_path);
    ChromeOptions options = new ChromeOptions();
    options.addArguments("test-type");
    options.addArguments("start-maximized");
    options.addArguments("--js-flags=--expose-gc");  
    options.addArguments("--enable-precise-memory-info"); 
    options.addArguments("--disable-popup-blocking");
    options.addArguments("--disable-default-apps");
    options.addArguments("test-type=browser");
    options.addArguments("disable-infobars");
    driver = new ChromeDriver(options);        
}

}

Remember to:

Replace http://google.com with your own_test_URL.
Replace package demo by package your_package_name.
Replace public class TestAnyURL_TestNG with public class your_class_name
Run as "TestNG Test"
Update me the status.
