[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

        //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;



        }

                scrollbarHeight=lessThenOnePageHeight;

                String groupName = groupEl.getText();



                



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



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

                }



            }



        }
