Galen on Jenkins not working

[axelbarfod1]

Hi I'm having the following issue when running galen on Jenkins (see error below). Locally the tests works but when it runs fine. Is there an extra configuration on Jenkins for Galen ?

[hypery2k]

on a server you'll either needs an Xserver (like Xvfb) installed or set headless execution for chrome to run graphical tests

[axelbarfod1]

how could I set headless on the chromedriver instance ?

[biswajit-713]

you may add headless to your chrome options. The python equivalent is options.add_argument('headless')

@biswajit-713 How to set headless for chrome when I'm using Galen JavaScript API

[axelbarfod1]

Yeah, I don't know how to start chrome using headless using the JS API is there a property on galen.config?

[axelbarfod1]

@hypery2k I have already installed xvfb. I use it to run my selenium tests and they run fine but for some reason which I can't understand is that galen isn't working on jenkins and local it does.

@axelbarfod1 I don't know you're concrete setup. But here is an example from this repo. Just create a job like this:

Hello @axelbarfod1 ,

This is only for JAVA users of Galen !

I have overriden some of the methods to use my own configurations.

Check this part in my code -

       try {
            driver = getDriver();
        } catch (RuntimeException e) {
            LOGGER.info(e + " , Hence instantiating new " + browser + " instance.");
        }

Full code here -

//public class MyGalenConfig extends GalenTestNgTestBase { //In this class

    @Override
    public WebDriver createDriver(Object[] args) {
        WebDriver driver = null;
        String browser = findBrowserName(args[0]);
        try {
            driver = getDriver(browser);
        } catch (Exception e) {
            e.printStackTrace();
        }
        if (args.length > 0) {
            if (args[0] != null && args[0] instanceof TestDevice) {
                TestDevice device = (TestDevice)args[0];
                if (device.getScreenSize() != null) {
                    driver.manage().window().setSize(device.getScreenSize());
                }
            }
        }
        LOGGER.info("\n\n+++++++++++++++ - Instance Divider - +++++++++++++++++++\n");
        LOGGER.info("Browser Driver : " + driver);
        return driver;
    }

    private String findBrowserName(Object arg) {
        String browser = ((UserData) arg).getBrowser();
        if(StringUtils.isEmpty(browser)){
            browser = "firefox"; //I used to get this from config file
        }
        return browser;
    }

    @Override
    public WebDriver getDriver(String browser) throws FileNotFoundException {
        WebDriver driver = null;
		
		/** Use the driver if already there is one **/
       try {
            driver = getDriver();
        } catch (RuntimeException e) {
            LOGGER.info(e + " , Hence instantiating new " + browser + " instance.");
        }


        if(driver == null){
            if(browser.equals(FIREFOX)) {
                setDriverPathInSystemProperty("webdriver.firefox.bin","firefox"));
                driver = new FirefoxDriver();
                driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);

            }else if (browser.equals(CHROME)) {
                setDriverPathInSystemProperty("webdriver.chrome.driver", "chrome"));
                driver = new ChromeDriver();
                driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
            }else if (browser.equals(INTERNET_EXPLORER)){
                setDriverPathInSystemProperty("webdriver.ie.driver", "internetExplorer");
                driver = new InternetExplorerDriver();
                driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
            }
        }
        return driver;
    }

Let me know if this doesn't work for you .
