Integrating Autoit and Selenium: Uploading a file using autoit

While automating a web application I faced a challenge. The challenge is integrate autoit and selenium. So I am going to share the problem domain and the coded solution below so that others can find it out helpful

Problem domain: I have a file located in my own machine which I need to upload in one of my web application project

Used tool:
1. Selenium for automating web application
2. Autoit for interacting with windows/ uploading a file from own local machine

Step 1: Autoit code
Write the Autoit code:

ControlFocus("File Upload","","Edit1")
ControlSetText("File Upload","","Edit1","D:\Test\Shp\Vegetation.zip")
ControlClick("File Upload", "", "Button1")

First write this autoit code and then save it using the extension, Example: fileupload.au3

Step 2: Compile script(Convert into .exe format)

Right click on the fileupload.au3 file and hit compile script, If you are using a 32 bit OS then choose x86 option and if you are using a 64 bit os then choose x64 option

Step 3: Integrating with selenium

Write only the following line in your selenium code where you need to upload you file

Runtime.getRuntime().exec("C:\\Users\\example\\Desktop\\fileupload.exe")

(It is the file path of the .exe file)

Then run your selenium code and observe the expected result

This code works fine for me hope you will find this helpfull

Draw in canvas using selenium web driver and java

Drawing 3 points which will create a polygon


WebElement element = driver.findElement(By.xpath("html/body/div[3]/div[2]/div[2]/div[2]/div/canvas"));

Actions builder = new Actions(driver);
    Action drawAction = builder.moveToElement(element,135,15)  // start point in the canvas
    //signatureWebElement is the element that holds the signature element you have in the DOM
              .click()
              .moveByOffset(200, 60) // second point
              .click()
              .moveByOffset(100, 70) // third point
              .doubleClick()
              .build();
    drawAction.perform();

Code academy: Function: 3/19: Calling a function with parameter

We've set up a function, square. Call it on the number 10 (by putting 10between the parentheses of square()) on line 9!

Solution:
def square(n):
    """Returns the square of a number."""
    squared = n**2
    print "%d squared is %d." % (n, squared)
    return squared
    
# Call the square function on line 9! Make sure to
# include the number 10 between the parentheses.

square(10)

== Search Text for Your Name ==
We'll want to place the if statement inside our for loop to make sure the program checks the if statement each time it moves forward through the loop. Essentially, the for loop is saying: "Hey program! Go through every letter in 'text'." The if statement will say: if you see something interesting, push that text into an array!"

var myArray =  ['a', 'b', 'c'];
myArray[0]; // equals a.

Instructions:
Add your if statement in the body of your for loop. It should check to see whether the current letter is equal to the first letter of your name. (Capitalization counts!)
There's no need to put anything between the {}s of your if just yet.

Solutions:

var text = "Hello world Keya how you doing Keya";
           
var myName ="Keya";
var hits = [];
for(var i=0; i<text.length; i++ )
{
    if (text[i]=== 'K')
    {
        }
    }

While loop: Tutorial 5/11
== Practice makes perfect ==
Problem: Write a while loop that logs "I'm looping!" to the console three times. You can do this however you like, but NOT with three console.log calls. Check the Hint if you need help!

Solve:
var count= 0;

var loop = function(){
    while(count < 3){
        console.log("I'm looping!");
        count++;
    }
};

loop();

def the_flying_circus():
    if 12 and 1 + 1 == 2:    # Start coding here!
        print "Yes, I'm greater than 11!"
        # Don't forget to indent
        # the code inside this block!
        return True
    elif 11 < 12:
        print "We are a circus of less than 12 men!"
        # Keep going here.
        return True
    else:
        print "We don't know how many people we are!"
        # You'll want to add the else statement, too!

Python datetime format

Problem domain:

1. Create a variable called now and store the result of datetime.now() in it.
2. Then, print the value of now.

Solve: 

from datetime import datetime

now = datetime.now()

print now

Output: 

current date

Printing current date year and month code

Format 1:

from datetime import datetime
now = datetime.now()
print now
print now.year
print now.month
print now.day

Format 2: from datetime import datetime
now = datetime.now()


print '%s/%s/%s' % (now.month, now.day, now.year, )

Format 3: from datetime import datetime
now = datetime.now()


print '%s:%s:%s' % (now.hour, now.minute, now.second )

Format 4: from datetime import datetime
now = datetime.now()


print '%s/%s/%s %s:%s:%s' % (now.month,now.day,now.year, now.hour, now.minute, now.second )

Faced the following problem for send keys in selenium webDriver in Java

Java is throwing the following error while working with selenium

Follow these steps in your eclipse:

1. Right click on your java project and select Build Path -> Click on
   Configure Build Path...
2. In project properties window, Click/select Java Compiler at the left
   panel
3. At the right panel, change the Compiler compliance level from 1.4 to 1.7
   (Select which is higher version in your eclipse)
4. Lastly Click on Apply and OK

Now check your code. it will never show the same error.

TestNG file execution Along with jar file.

TestNG file execution Along with jar file.
1. Create a main class 1st

package Testcase;

import com.beust.testng.TestNG;

@SuppressWarnings("deprecation")
public class MainOne {

public static void main(String[] args) {
TestNG testng = new TestNG();
         Class[] classes = new Class[]{houpad.class}; //houpad is the class where i included all the                                                                                             //testNG executable testcases.
         testng.setTestClasses(classes);
         testng.run();

}

}

To export a jar file
1. Run the main class then
2. Right click on the package name> Export> Java> rurnnable JAR file> from the launch configuration select the main class created above.> Hit finish.
3. Now double click on the jar file
4. It will show the execution
