GeckoDriver error in TestNG that works in plain JAVA

Question

The gecko driver path that works in JAVA is causing an error in TestNG.

Environment:

• Win 10
• FF
• selenium-java-3.0.1
• geckodriver-v0.11.1-win64
• eclipse-java-neon-2-win32-x86_64

I suspect I'm placing the GeckoDriver path in the:

1) wrong format and/or

2) wrong place in the TestNG script, but it might be something far more basic, as I'm a novice in this.

Working Code in JAVA :

package foo;
import java.util.List;
... (various 'import')

public class foo02 {    
    public static void main(String[] args) {

    System.setProperty("webdriver.gecko.driver", "C:\\Users\\TestTools\\geckodriver-v0.11.1-win64\\geckodriver.exe"); 

    WebDriver driver = new FirefoxDriver();
    ...

Non working code with TestNG:

package fooNGpackage;

import org.openqa.selenium.WebDriver;
... (various 'import')

public class newtestclss {
     WebDriver driver;

 @BeforeTest
 public void start(){
        System.setProperty("C:\\Users\\TestTools\\geckodriver-v0.11.1-win64\\geckodriver.exe", null); 

 driver = new FirefoxDriver();
 }

 @Test
 public void Test(){ 
  System.out.println("Loading Google search page");
  driver.get("http://google.com");
  System.out.println("Google search page loaded fine");
 }

 @AfterTest
 public void close(){
 driver.quit(); 
 }
 }

Error when run as TestNG:

Your suggestion is greatly appreciated. HK

Answer 1

The syntax for setProperty() method is:

System.setProperty("<driver we want to use in the program>", 
                   "<path where the driver exists>");

As per the question,

In java you have mentioned correctly.

In TestNG, in place of 'driver to be used' you have mentioned 'driver path' and in place of 'driver path' you have pointed to null.

Correct way:

@BeforeTest
public void start(){
    System.setProperty("webdriver.gecko.driver", "C:\\Users\\TestTools\\geckodriver-v0.11.1-win64\\geckodriver.exe");
    driver = new FirefoxDriver();
}
