Ruby Installation

In Windows, you can use either RubyInstaller or pik.

1| Download rubyinstaller
2| Check Ruby version
Start > Interactive Ruby
RUBY_VERSION

3| Install Selenium WebDriver library for Ruby
selenium-webdriver-2.41.0.gem
INSTALL > gem install selenium-webdriver

4| Download Devkit before installing json
5| Extract DevKit to path C:\Ruby200\DevKit
6| Open cmd prompt
> cd C:\Ruby200\DevKit
> ruby dk.rb init
> ruby dk.rb review
> ruby dk.rb install


INSTALL > gem install json

7| Download Ruby DLTK plugin for Eclipse IDE [Go to Eclipse Marketplace and search Ruby DLTK]

8| Go to Windows > Preferences > Ruby - Interpreters

9| Click on 'Add' and Locate Ruby.exe  "C:\Ruby200\bin\ruby.exe"

10| Create a New Ruby Project
Right click on package Explorer > New > others 

11| Type 'Ruby'.
12| Select 'Ruby Project' and press Finish.

13| Create a new Ruby module.
Right click on package > New > Ruby module

14| Develop your Ruby selenium script like sample given below

require "selenium-webdriver"

driver = Selenium::WebDriver.for :firefox
driver.navigate.to "http://google.com"

element = driver.find_element(:name, 'q')
element.send_keys "Prashanth Sams"
element.submit

driver.quit

15| Rick click on program Run > Ruby Script



Note| 
1| Rack is a web server interface used for developing web applications in Ruby; Rack is used by almost all Ruby web frameworks and libraries, such as Ruby On Rails and Sinatra.
2| RubyGems is a package manager for Ruby programming language.

Handle Download popup using Firefox Browser Profile

Firefox Browser Profile [Download Files]

This is the continuation of my previous topics, #link1 and #link2.  The simplest way to ignore Browser pop-up and save files is to make use of Browser profiles;  There are couple of ways to do this [can be done either manually or using scripts]

Advantages of using Browser Profile
    1| Skip download pop-up and save the files on specific folder
    2| No need of 3rd party tools like AutoIT or Java Robot



#Method1

Before you start working with pop-ups on Browser profiles, make sure that the Download options are set default to Save File.

(Open Firefox) Tools > Options > Applications

#Method2

Make use of the below snippet and do edits whenever necessary.


FirefoxProfile profile = new FirefoxProfile();

String path = "C:\\Test\\";
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", path);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/msword, application/csv, application/ris, text/csv, image/png, application/pdf, text/html, text/plain, application/zip, application/x-zip, application/x-zip-compressed, application/download, application/octet-stream");
profile.setPreference("browser.download.manager.showWhenStarting", false);
profile.setPreference("browser.download.manager.focusWhenStarting", false);  
profile.setPreference("browser.download.useDownloadDir", true);
profile.setPreference("browser.helperApps.alwaysAsk.force", false);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.download.manager.closeWhenDone", true);
profile.setPreference("browser.download.manager.showAlertOnComplete", false);
profile.setPreference("browser.download.manager.useWindow", false);
profile.setPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);
profile.setPreference("pdfjs.disabled", true);
       
driver = new FirefoxDriver(profile);

Java AWT Robot | Selenium Uses

Note|  Text in Blue [#PYTHON] and Orange [#JAVA] can be edited or mentioned important for the entire blog. All the posts are practically done by me.

Java Robot

This is the continuation of one my previous topics, link here.  Selenium doesn't give support on automating or handling Browser pop-ups and Native OS pop-ups.

There are 3 ways to make it work.
     1| Java.awt.Robot Toolkit
     2| 3rd party tools like AutoIT [check link here]
     3| Browser Profile [check link here]

Fig. Browser PopUp

Java Robot handles Mouse Actions and Keyboard Actions. For example, some of the most important functions are as follows:

      1| keyPress()
      2| keyRelease()

      3| mousePress()

      4| mouseRelease()

      5| Mousemove()

Handle Browser Pop-up

Note| 
1| The below snippet is used to save a file from Download Browser Pop-up shown above in Fig.
2| The below co-ordinates are set for Screen resolution | 1920 x 1080
3| Window status | Maximized
4| Customize the xy co-ordinates in-case if you are using different screen resolution


Robot r = new Robot();
// click Save File 
r.mouseMove(787, 544); // move to co-ordinate Location
r.mousePress(InputEvent.BUTTON1_MASK); // Left Mouse click - Press
r.mouseRelease(InputEvent.BUTTON1_MASK); // Left Mouse click - Release 
r.delay(5); // wait for 5 millisecs
// click ok
r.mouseMove(1032, 641); // move to co-ordinate Location
r.mousePress(InputEvent.BUTTON1_MASK); // Left Mouse click - Press
r.mouseRelease(InputEvent.BUTTON1_MASK); // Left Mouse click - Release

Robot Functions

InputEvent.BUTTON1_MASK // Left button
InputEvent.BUTTON2_MASK // Middle button
InputEvent.BUTTON3_MASK // Right button



Middle click | Press & Release
Robot r = new Robot();
r.mousePress(InputEvent.BUTTON2_MASK); 
r.mouseRelease(InputEvent.BUTTON2_MASK);


Right click | Press & Release
r.mousePress(InputEvent.BUTTON3_MASK); 
r.mouseRelease(InputEvent.BUTTON3_MASK);


Scroll Mouse
r.mouseWheel(7);


Pixel Color | RBG
System.out.println(r.getPixelColor(923, 87));
OUTPUT|
java.awt.Color[r=142,g=209,b=224]


Get Current Mouse position [location]
System.out.println(MouseInfo.getPointerInfo().getLocation());
OUTPUT|
java.awt.Point[x=735,y=633]


Get Screen Resolution | Dimension
System.out.println(Toolkit.getDefaultToolkit().getScreenSize());
OUTPUT|
java.awt.Dimension[width=1920,height=1080]


Screen Capture
java.awt.Dimension size = Toolkit.getDefaultToolkit().getScreenSize();
Robot r = new Robot();
BufferedImage img = r.createScreenCapture(new Rectangle(size));
File path = new File("C://screen.jpg");
ImageIO.write(img, "JPG", path);
or|
Robot r = new Robot();
BufferedImage img = r.createScreenCapture(new Rectangle(0, 0, 100, 100));
File path = new File("C://screen.jpg");
ImageIO.write(img, "JPG", path);


Enter/Type Text
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.lang.reflect.Field;

Robot r = new Robot();     
driver.findElement(By.id("Value")).click();  
typeKeys("Prashanth Sams", r);

public static void typeKeys(String str,Robot r)
{
 for(int i=0;i<str.length();i++)
{
  typeCharacter(r, ""+str.charAt(i));
}
}
public static void typeCharacter(Robot robot, String letter)
{
 try
{
  boolean upperCase = Character.isUpperCase( letter.charAt(0) );
  String variableName = "VK_" + letter.toUpperCase();
  Class clazz = KeyEvent.class;
  Field field = clazz.getField( variableName );
  int keyCode = field.getInt(null);

  robot.delay(1000);

  if (upperCase) robot.keyPress( KeyEvent.VK_SHIFT );

  robot.keyPress( keyCode );
  robot.keyRelease( keyCode );

  if (upperCase) robot.keyRelease( KeyEvent.VK_SHIFT );
 }
 catch(Exception e)
 {
  System.out.println(e);
 }
 }


Keyboard Actions
r.keyPress(KeyEvent.VK_ENTER); // Press Enter Key
