A concept of using Galen together with TestNG

        List<PageSection> pageSections = spec.findSections(tagsToInclude);
        
        // allows to subscribe for all validation events. Could also be null
        ValidationListener validationListener = configureValidationListener();
        SectionValidation sectionValidation = new SectionValidation(pageSections, new PageValidation(browser, page, spec, validationListener, sectionFilter), validationListener);
        
        List<ValidationError> errors = sectionValidation.check();
        if (errors != null) {
            //TODO do something with errors
        }
    }
    
    public ValidationListener configureValidationListener() {
        //TODO 
    }
    
    public WebDriver createDriver(String url, Dimension screenSize) {
        WebDriver driver = initDriver();
        driver.get(url);
        driver.manage().window().setSize(screenSize);
        return driver;
    }
    
    public WebDriver initDriver() {
        //TODO initialize driver
    }
    
    @DataProvider
    public Object[][] allMyDevices() {
        return new Object[][]{
          [size(400, 800), asList("mobile","all")],
          [size(600, 800), asList("tablet", "all")],
          [size(1024, 768), asList("desktop", "all")],
        };
    }
    
    public static Dimension size(int w, int h) {
        return new Dimension(w, h);
    }
}

What is the Purpose of initDriver() method? Just to initialise the driver or is it meant to do something else also?

Don't think I can do much with this without the ValidationListener being implemented, any idea when you are planning to get to it?

The tests are running fine and able to access the spec file. Is there a way I can get the htmlreports using Maven goals? Like a maven version of galen check --htmlreport "reports"

Hi Rashi!
The initDriver method is just a placeholder for WebDriver initialization
As for ValidationListener at the moment there is no proper reporting implemented which could be used as a library. Whole reporting mechanism is messed up and I am planning to refactor it and implement a simpler one. In my case I need it for this ticket galenframework/galen#62. But that would work in your case as well.
