please provide solutions for this.

Answer 1

The error you are seeing says it all Build info: version: Driver info: driver.version:. Your build info & version are not getting captured and printed by gecko driver. The main reason is Selenium, GeckoDriver & Mozilla Firefox Browser versions are not not compatible across your Test Environment.

You have mentioned Selenium Webdriver 3.3.1 gecko driver 0.18 Firefox 55.0.03

The release notes of geckodriver v0.18.0 clearly mentions the following dependency:

Note that geckodriver v0.16.0 is only compatible with Selenium 3.4 and greater.

As you are trying to use Selenium v3.3.1 through geckodriver v0.18.0 hence you see SessionNotCreatedException.

Answer 2

Download latest version of selenium jar files i.e 3.5 and try it. As I read you used the geckodriver v0.18 so use latest jar for that.

Answer 3

Download the selenium latest stable version i.e selenium 3.5.3 and create the driver as below.

System.setProperty("webdriver.gecko.driver",geckoDriverPath);
FirefoxProfile ffProfile = new FirefoxProfile();
ffProfile.setPreference("browser.tabs.remote.autostart.2", false);
FirefoxOptions options=new FirefoxOptions();
options.setProfile(ffProfile);
driver = new FirefoxDriver(options);

Download the latest geckoDriver from below link.

Link to download geckodriver

In the code below line is to solve the issue with browser crashing while quitting the driver.

ffProfile.setPreference("browser.tabs.remote.autostart.2", false);
