org.openqa.selenium.SessionNotCreatedException: Unable to find a matching set of capabilities while initiating Firefox v37 through Selenium v3.11.0

Question

I am trying to run test a run a website in Firefox, but I am getting error "The path to the driver executable must be set by the webdriver.gecko.driver system property;" I have set the path correctly, still don't know where the problem is. Here is my code:

if (browsers.equalsIgnoreCase("Firefox")) 
{
        String driverPath = System.getProperty("user.dir") + "\\src/test/java\\drivers\\geckodriver.exe";
        System.setProperty("webdriver.firefox.marionette", "false");
        driver = new FirefoxDriver();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
    } else if (browsers.equalsIgnoreCase("Chrome")) {
        // String driverPath = System.getProperty("user.dir") +
        // "\\src\\Drivers\\chromedriver";
        // System.setProperty("webdriver.chrome.driver", driverPath);
        System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
        driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    }

Here is the Failure Trace of my code:

To keep things simple, as you are using Selenium Client v3.11.0 and Firefox v37 you need to download the latest GeckoDriver from mozilla/geckodriver and save it any where within your system. Next within the System.setProperty() line pass the Key webdriver.gecko.driver along with the Value as the absolute path of the GeckoDriver and finally through DesiredCapabilities class set the capability marionatte to false and merge into an instance of FirefoxOptions instance to initiate the Firefox browser as follows :

System.setProperty("webdriver.gecko.driver", "C:/path/to/geckodriver.exe");
DesiredCapabilities dc = new DesiredCapabilities();
dc.setCapability("marionatte", false);
FirefoxOptions opt = new FirefoxOptions();
opt.merge(dc);
FirefoxDriver driver =  new FirefoxDriver(opt);
driver.get("https://stackoverflow.com");
System.out.println("Application opened");
System.out.println("Page Title is : "+driver.getTitle());
driver.quit();

Update

As per your comment update you are using GeckoDriver v0.20.1.

But if you look back at the Release Notes of GeckoDriver v0.18.0 it clearly mentions :

geckodriver now recommends Firefox 53 and greater

So using GeckoDriver v0.18.0 and above you have to mandatory use Firefox 53 and greater. To get rid of this constraint you can downgrade either to any of these versions :

GeckoDriver v0.17.0
GeckoDriver v0.16.1

This code is giving me error " Unable to find a matching set of capabilities", That mean it did not have set the capability marionatte to "false" – Rohn Kerry Apr 12 '18 at 10:50

Just to update you , I have done some changes- dc.setCapability("marionatte", false); FirefoxDriver driver = new FirefoxDriver(dc); ....This have initiated the Firefox browser but now I am getting the error "connection refused", Why is this happening? – Rohn Kerry Apr 12 '18 at 11:12
@RohnKerry Update the question with the complete error stack trace for further analysis please – undetected Selenium Apr 12 '18 at 11:18
I have edited and added the error stack trace of my code. – Rohn Kerry Apr 12 '18 at 11:44

I have found the solution for that. The code is : System.setProperty("webdriver.firefox.marionette","D:\\geckodriver.exe"); – Rohn Kerry Apr 12 '18 at 12:08
Wait, that's **not** the right solution, gimme some time to get back to you. Update me your **GeckoDriver** please. – undetected Selenium Apr 12 '18 at 12:13

My geckodriver version is- geckodriver-v0.20.1 – Rohn Kerry Apr 13 '18 at 05:32
the solution I pasted in comments is working fine for me, So I guess it is the right solution. – Rohn Kerry Apr 16 '18 at 05:14
@RohnKerry Checkout my answer update and let me know the status – undetected Selenium Apr 16 '18 at 05:28

This is how system property is set:

System.setProperty("webdriver.gecko.driver", "C:\\...\\geckodriver.exe");

I had this error for 2 days, the solution for me was in Set.Platform, put Platform.ANY or Platform.Windows because Platform.WIN10 not worked, marionette wasn't necessary.

public class Main { public static RemoteWebDriver driver;

public static void main(String[] args) throws MalformedURLException {
    System.setProperty("webdriver.gecko.driver", "D:/Lib/geckodriver.exe");
    DesiredCapabilities desiredCapabilities = new 
                                        DesiredCapabilities().firefox();
    desiredCapabilities.setPlatform(Platform.ANY);
    desiredCapabilities.setBrowserName("firefox");

    driver = new RemoteWebDriver(new URL("http://172.20.19.182:5557/wd/hub"), 
                                                desiredCapabilities);
    driver.navigate().to("http://www.google.com");
    driver.findElementByName("q").sendKeys("execute automation");
    driver.findElementByName("q").sendKeys(Keys.ENTER);
    driver.close();
    // write your code here
}

you are using user.dir that basically means : current working directory

Here is the code that let you initialize firefox browser using selenium.

public static void main(String[] args) {


            System.setProperty("webdriver.gecko.driver", "C:\\your\\gecko\\driver\\path\\geckodriver.exe");
            driver = new firefoxDriver();

That's it ! you can use Firefox driver to performs several operations like :

1.  driver.get(String args0);
2.  driver.getCurrentUrl();
3.  driver.getPageSource();
4.  driver.getTitle();
5.  driver.findElememt(By args0);
6.  driver.findElements(By args0);
7.  driver.naviagate();
8.  driver.manage();
9.  driver.close();
10. driver.quit();
11. driver.switchTo();
12. driver.getWindowHandle();
13. driver.getWindowHandles();

Please let me know if you have any concerns related to this.

That is correct but the issue is, I am using firefox version 37, So I have to put marionette= false. Now we can send only two string values in .setProperty.So where I can put the path to the geckodriver? – Rohn Kerry Apr 12 '18 at 07:18
Which version of selenium you are using with FF37? – cruisepandey Apr 12 '18 at 07:19
Like can we do that- System.setProperty("webdriver.firefox.marionette=false", "driverPath"); ? – Rohn Kerry Apr 12 '18 at 07:19
I am using selenium 3.11.0 – Rohn Kerry Apr 12 '18 at 07:21
@RohnKerry : I'm not sure about this. Give me some time, if I will find anything, I will update you ! – cruisepandey Apr 12 '18 at 07:23
Sure cruisepandey, I appreciate your help and efforts to help me resolve my issue. – Rohn Kerry Apr 12 '18 at 07:24
No issue @RohnKerry. Cheers ! – cruisepandey Apr 12 '18 at 07:25
@RohnKerry why don't you try adding set property twice? One for marinette and other for driver path – Rabia Asif Apr 12 '18 at 07:25
Still no success. – Rohn Kerry Apr 12 '18 at 07:52

Just updated your code. You will have to set driver path while setProperty and user webdriver.gecko.driver for latest firefox driver.

    if (browsers.equalsIgnoreCase("Firefox")) {
            String driverPath = System.getProperty("user.dir") + "\\src\\test\\java\\drivers\\geckodriver.exe"; 
            System.setProperty("webdriver.firefox.driver", "driverPath"); 
            DesiredCapabilities capabilities = new DesiredCapabilities();
            capabilities.setCapability("marionette", false); 
            FirefoxOptions options = new FirefoxOptions(); 
            options.merge(capabilities);
            FirefoxDriver driver = new FirefoxDriver(options);
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        } 
        else if (browsers.equalsIgnoreCase("Chrome")) {
            // String driverPath = System.getProperty("user.dir") +
            // "\\src\\Drivers\\chromedriver";
            // System.setProperty("webdriver.chrome.driver", driverPath);
            System.setProperty("webdriver.chrome.driver", "D:\\chromedriver.exe");
            driver = new ChromeDriver();
            driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
        }

Let me know.

But the problem is I am not using latest firefox version, I am using ff version 37. That is why I have set the marionette= false, for compatibility. – Rohn Kerry Apr 12 '18 at 07:22
@RohnKerry, the latest Firefox version is 59 and you don't need to set marionette for that if you are using ff version 37 then you have to use compatible `firefoxdriver.exe` – BhavinD. Apr 12 '18 at 07:42
So you mean to say that I have to download a compatible Firefox Webdriver for ff version 37? – Rohn Kerry Apr 12 '18 at 08:13
No need to download. you can use latest FireFox geckodriver and you can set marionette=false using _DesiredCapabilities_ class. – BhavinD. Apr 12 '18 at 08:39
Yes I have already did that but the problem is you can pass two values to the .setProperty() and I have to also give path to geckodriver in that. – Rohn Kerry Apr 12 '18 at 09:53
I have also tried the code : String driverPath = System.getProperty("user.dir") + "D:\\Workspace\\YourLogo\\src\\test\\java\\drivers\\geckodriver.exe"; System.setProperty("webdriver.firefox.driver", "driverPath"); DesiredCapabilities capabilities = DesiredCapabilities.firefox(); capabilities.setCapability("marionette", false); driver = new FirefoxDriver(); – Rohn Kerry Apr 12 '18 at 10:12
@RohnKerry, Please look my updated answer. Added DesiredCapabilities and FirefoxOptions. – BhavinD. Apr 12 '18 at 10:23
May I know what is this for?- FirefoxOptions options = new FirefoxOptions(); FirefoxDriver driver = new FirefoxDriver(options); – Rohn Kerry Apr 12 '18 at 10:27
