Basic Code

1.  Find the top 3 elements of an array, Do not use sorting use 3 variables.
(Amazon Interview Question)
public class LargeNumberArray {
 public static void main(String args[]){
   int a[]={7,2,8,1,3,5,10,0,12,11};
   int large=a[0],second=a[0],third=a[0];
   int index=0,index1=0,index2=0;
   for (int i=0;i<a.length;i++)
   {
     if(a[i]>=large)
     {
        large=a[i];
        index=i;  
     }
   }
   for (int i=0;i<a.length;i++)
   {
      if(a[i]<large && a[i]>second))
      {
         second=a[i];
         index1=i;
      }
    }
   for (int i=0;i<a.length;i++)
   {
      if(a[i]<second && a[i]>third))
      {
         third=a[i];
         index2=i; 
      }
   }
   System.out.println("Large Number: "+large+ " Index: "+index);
   System.out.println("Large Number: "+second+ " Index: "+index1);
   System.out.println("Large Number: "+third+ " Index: "+index2);
  }
}

2.  Program for Fibonacci series.

String s=br.readLine();
int n=Integer.parseInt(s);
System.out.print("Series=");
fibonacci(n);
}
public static void fibonacci(int n)
{
int a=0,b=1;
for(int i=0;i<n;i++)
{
System.out.print(a+", ");
a=a+b;
b=a-b;
}
}
}

3. Program to check Palindrome Number.

while(number>0)
{
temp=number%10;
number=number/10;
reversed=(reversed*10)+temp;
}

        a=a*b; // a=12
        b=a/b; // b=3
        a=a/b; // a=4
        System.out.println("**** Swapping the values ****");
        System.out.println("A=> "+a);
        System.out.println("B=> "+b);
    }
    catch (NumberFormatException e){
        System.out.println("Please Enter valid Number");
        swap();
    }
}
}

Data Driven Frame Work

Data Driven Frame Work

     One of the widely used frame work  .
   
     In this frame work the whole automation process is driven by data( saved in excel,word doc or Data base)
 
     In the link below

    Key Word Driven Framework , i had explained how the key word driven frame work works

Please find the image below which is self explanatory

In the above image we are using 2 Excel sheet

1. Driver sheet : Which drives the whole automation
2. Data Sheet : Which provides the input to the modules

Driver sheet

Name itself tells it drives the whole automation . In the above Sheet we have 2 coloumns

Module name and ExecuteFlag

Module name = Specifies the name of the module to run or name or the test case

Execute Flag =  Specifies whether the Module to be run or not ( if the value is "Y" execute the corresponding code else skip it )


Complete flow 


Let us see with an example the

We have 3 rows inside the Driver sheet , as per the above description only code related to LoginMail and SendMail as to be execute .

Steps

1.  main() Method reads the Driver sheet
2. Checks for Execute Flag for "Y" , if its Y , it captures the Module name 
3. Checks with the case statement and compare with the case values , if anything is matched , it has to execute the corresponding code , Here comes the Data Sheet , This sheet can be used to give the input for the modules (in the above example we can see LoginName and Pwd required for logining in )
4. Repeat the above steps until no rows in Driver sheet

Key Word Driven Framework

Key Word Driven Framework
Framework where for a particular test case, you would first identify a set of Keywords and then associate a method (or function) to each of these keywords.
Consider for example login flow of Face book is the case to be automated
Steps 1 . Login to Face Book
Steps 2 . Check any notifications
Steps 3 . Logout

Now we have got the steps ( taking pure modular approach we can divide the steps into modules or functions )
So there are 3 methods / functions

Test cases

1. Login to Facebook
2. Check the notifications
3. Logout from Face book

Once Test cases are identified 

        Identify the Keywords ( Keywords can be any name which is easier to remember or understand)

       

1. FBLogin 
2. FBNotificationCheck
3. FBLogout

Once keywords are identified next step is to associate the Keywords to Methods

Now according to the above case we need to do 3 steps

1. Create a keyword and save it somewhere

2. Develop a module 

3. Associate the keyword and the respective modules

Part of the work is done , now the flow comes to picture

Below is the list of common components or questions appears in most of the keyword driven  frameworks.

1. Where to save the Keywords and Modules

         Once the Keywords are identified we can use Excel sheet to save the Keywords, but write a 

          Method(Main() ) to open the excel sheet and get the keywords 

2. Where to save the Modules ?

         In Keyword Driven framework methods play a very important role , so You would have to built all the          necessary intelligence in the java methods so that it can read the excel sheets and call the different                  Modules/Methods based on the Keywords.

         Better we save the methods in a separate folder naming Business flow ( as per individuals interest or              project requirements)

         Build all your business flow or function intelligence here and save as separate files or single , depends            on the developer and requirements

3. Data sheet needed ? 

         It depends – To save the data we need to for the Test case to be used by the application

4. Test Scripts ( As per project requirement)

        

         You can have separate test scripts for each manual test case or a single driver script that will execute            all the test cases

below flow indicates the full flow 

From the above figure, you can see that the generic flow of a Keyword Driven Framework is something like this -

1) MAIN Method  calls the other Methods which has code to read the excel sheet

2) The Methods called from the Main method opens the excel sheet and reads the first keyword associated with the test case.

3) Once the keyword is read from the excel sheet , It searches for the associated Methods ,Once the associated methods are identified  then the method is excuted on the application that is being tested.

4) Control returns back to main function (in Step 2) which then reads the next keyword. Steps 2 to 4 are repeated till all the keywords associated with a particular test case are called.

Now how to associate the keywords is important ( it depends on project )

If we search in the net for Key word Driven Framework . We can find wide variety of answers .

It depends on the requirements

Broadly dividing it into 2 ways

1 . Associate the keywords to a whole function or method

2 . Associate the keywords to a object level operations like
associating one key word for entering username , one for entering password , one for clicking button and so on


To Explain the above two implementation let us consider 3 test cases

TC_01= Login to Facebook , check for notification's , logout
TC_02 = Login to Facebook , check for friends request , logout
TC_03 = Login to Facebook , check for birthday notifications , logout


Associate the keywords to a whole function or method

  This is the most general format that is used in many of the places

 
   In the above diagram we can see how the associations are done

   Now when the Main method is called it opens the excel sheet , reads the first line .

1. It captures the Test case name TC_01 , once the Test case name is captured
2. It capture the first Keyword i.e FBLogin in this case, once the keyword is got , it checks for the associated method and execute it against the AUT
3. Step 2 is repeated until all the keywords are done for First case ( TC_01)
4. Once the TC_01 is done it jumps to next Test case(TC_02) and repeat the 2 step for its corresponding keywords

Associate the keywords to a object level operation

This is another method of implementation

In the above diagram we can see how the associations are done on operations level ( its self explanatory)

Now when the Main method is called it opens the excel sheet , reads the first line .

1. It captures the BrowserType , Title , now the element is captured .
2. Once the element is captured it checks the properties 
3. Once the properties are captured it checks for the operations to be performed 
4. Here the values are associated to it
