Verifying the text using browser popup 'Open' file functionality

Read text from Notepad

Here's the program to demonstrate reading the text data from notepad using "java.awt" API.

This is done by following 3 steps:
1. Open the file present in the machine using notepad application.
2. Copy text from notepad using keyboard events(i.e. Cntrl+C).
3. Once the text data is copied, close the notepad and print the captured text(i.e. data captured from notepad).

Sample File:

Sample Program:

package pack1;

import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.Transferable;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.awt.event.KeyEvent;
import java.io.IOException;

/** Reading data from notepad.
 *
 * @author http://automation-home.blogspot.in/
 */
public class ReadTextFromNotepad {

static Runtime rs = Runtime.getRuntime();
static Robot robot = null;
static String filePath = null;
public static void main(String[] args) {

try {
robot = new Robot();

//Note: file should present at path "C:\\Content.txt"
filePath = "C:\\Content.txt";

//Opens the file in notepad.
openNotepad();

//Reads the data from notepad.
String[] notepadContent = readFromNotepad();

//Close the notepad.
closeNotepad();

//Print the data(i.e. text captured from notepad).
for (String text : notepadContent) {
System.out.println(text);
}

} catch (Exception e) {
System.out.println(e);
}
}

/** Opens the file in notepad.
*
*/
public static void openNotepad() {
try {
rs.exec("notepad "+filePath);
robot.delay(500);
} catch (IOException e) {
e.printStackTrace();
}
}

/** Read's the data from notepad.
*
* @return notepadContent as String[]
*/
public static String[] readFromNotepad() {

// Copy text from notepad.
String[] notepadContent = null;
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_A);
robot.keyPress(KeyEvent.VK_C);

robot.keyRelease(KeyEvent.VK_C);
robot.keyRelease(KeyEvent.VK_A);
robot.keyRelease(KeyEvent.VK_CONTROL);

Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable contents = clipboard.getContents(DataFlavor.stringFlavor);
try {
String strContent = (String) contents
.getTransferData(DataFlavor.stringFlavor);
notepadContent = strContent.split("\n");
} catch (UnsupportedFlavorException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

return notepadContent;
}

/** Closes the opened notepad application.
*
*/
public static void closeNotepad() {
robot.keyPress(KeyEvent.VK_ALT);
robot.keyPress(KeyEvent.VK_F);
robot.keyPress(KeyEvent.VK_X);

robot.keyRelease(KeyEvent.VK_X);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_ALT);
}
}

Output:

Note:
1. Before executing above sample program, file should be present in the file path(i.e. specified in the variable "filePath").
2. While the program is executing don't move the mouse or type(i.e. don't take over the keyboad/mouse control).

Verifying the text using browser popup 'Open' file functionality

Most of the time, we verify the text present in the file by downloading the file(i.e. saving the file into the machine) and reading the data present in the file using the 'java.io.*' API.

Below program demonstrates verifying the text present in the file without saving the file i.e. by using browser's 'Open' file functionality.

Manual Steps:
1. Open the URL 'https://code.google.com/p/selenium/downloads/detail?name=downloads_location&can=2&q='
2. Click on download button/link
3. Popup appears(by default 'Open with' radio button is selected).
4. Click on popup 'OK' button (or) Keyboard 'Enter' key
5. File is opened.
6. Verify the text in the opened file and close the file

Sample automation script to demonstrate the above manual steps:

Output:

Note:
1. Above program is verified only on windows machine.
2. Program/script work's only with text files(i.e. txt files).
3. While the program is executing don't move the mouse or type(i.e. don't take over the keyboad/mouse control).
