[Selenium]Turn Page By Scroll Bar

Description:

Need to turn page by operating scroll bar and find out the element in the current page.

Previous page will not exist in DOM structure when turning page.

Solution:

1. Get the total height, button height, scroll bar height
2. Calculate total move height, totalMoveHeight = totalHeight - 2*buttonHeight - scrollbarHeight
3. Calculate page number, pageNum =  totalMoveHeight/scrollbarHeight
4. Calculate the last page when it is less then a whole page, lessThenOnePageHeight = totalMoveHeight%scrollbarHeight
5. Turn page according to the page number and lessThenOnePageHeight

public void seleteTemplate_NotClassifiedFactsheet(String template){

        //Scroll the scroll bar page by page

        Actions actions = new Actions(page.getDriver());

        int totalHeight = page.getDiv_scrollbar_TemplateMappingSetting().getSize().getHeight();

        int buttonHeight = page.getButton_ScrollbarDown().getSize().getHeight();

        int scrollbarHeight = page.getScrollbar_TemplateMappingSetting().getSize().getHeight();

        int totalMoveHeight = totalHeight - buttonHeight - buttonHeight - scrollbarHeight;

        int pageNum = totalMoveHeight/scrollbarHeight;

        int lessThenOnePageHeight = totalMoveHeight%scrollbarHeight;

        if(lessThenOnePageHeight>0){

            pageNum+=1;

        }

        for(int i=0;i<pageNum;i++){

            if ((i==(pageNum-1))&&(lessThenOnePageHeight>0)) {

                scrollbarHeight=lessThenOnePageHeight;

            }

            actions.dragAndDropBy(page.getScrollbar_TemplateMappingSetting(), 0, scrollbarHeight).perform();

            SeleniumUtil.sleep(1);

            List <WebElement> groupList = page.getGroupListInTemplateMapping();

            int groupNum = groupList.size();

            for(int j=0;j<groupNum;j++){

                WebElement groupEl=groupList.get(j);

                String groupName = groupEl.getText();

                if(groupName.equals("Not Classified")){

                    System.out.println("Find Group : "+groupName+" in page "+i);

                    WebElement factsheetTemplateEl=page.getDDL_NotClassifiedFactsheet();

                    factsheetTemplateEl.click();

                    page.getLink_Template(template).click();

                }

            }

        }

    }
