### 2 :: Write the test cases for a vending machine?

Assume tha tvending machine can provide tea, coffee and

milk, without taking any money or coin.

Firast we have to create finite state diagram for the test

case solution.

initial state ---->> coffee ------>> tea--------->> milk

this is the one test case where user can first ask for

coffee from initial state and then ask for tea and milk.

Now we have to take all the +ve test cases where user can

move from one state to another state.

### 3 :: Suppose You have 3 jars. Each jar has a label on it: white, black, or white&black. You have 3 sets of marbles: white, black, and white&black. One set is stored in one jar. The labels on the jars are guaranteed to be incorrect (i.e. white will not contain white). Which jar would you choose from to give you the best chances of identifying the which set of marbles in is in which jar?

there will be 2 combinations of the incorrect labeling.

lets suppose A,B,C are three jars and A has white, B has

Black and C has both of them.

now possible labeling will be A:B; B:B&W; C:W or A:B&W; B:W,

C:B . There cannot be other combinations...try it.

now in either of cases you choose the jar labeled with B&W

i.e mixture. and see which color of marbles are there. It

wont have both as it is incorrectly labeled. So it will be

the jar of such type of marbles and the remaining jars can

be easily identified with the justification of incorrect

labeles.

### 4 :: Write the InStr function. Write the test cases for this function?

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace InStr

{

class Program

{

static void Main(string[] args)

{

//test case 1, should return -1

string txt = "this is a test";

string searchString = "ae";

Console.WriteLine(InStr(txt, searchString));

//cast case 2, should return 2

txt = "this is a test";

searchString = "is";

Console.WriteLine(InStr(txt, searchString));

Console.Read();

}

//return the position of the first occurrence of one

string "searchString" within another "txt"

//return -1 means cannot find

static int InStr(string txt, string searchString)

{

return txt.IndexOf(searchString);

}

}

}

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace InStr

string searchString = "ae";

Console.WriteLine(InStr(txt, searchString));

txt = "this is a test";

searchString = "is";

Console.WriteLine(InStr(txt, searchString));

Console.Read();

}

//return the position of the first occurrence of one

string "searchString" within another "txt"

//return -1 means cannot find

static int InStr(string txt, string searchString)

{

return txt.IndexOf(searchString);

}

}

}

### 5 :: Write a function that counts the number of primes in the range [1-N]. Write the test cases for this function?

This is what I came up with (C#):

PSEUDO:

-Craete a list of numbers uptill n number - n being int

parameter

-Pass this list into a function to check for primilaty for

the number and then print primes wile we count for primes

BACKGROUND OF THIS SOLUTION:

THEORY:

- we know primes are the numbers starting from 2 are

divisible with 1 and themselves only i.e. n being a prime

number can only be divisble as n/n or n/1. testing from a

prime is called "primilatiy test" for a number...

-the simplest primality test is to see if given a number n

is divisible by an integer m from 2 to n-1. If n is

divisible by n then n is a composite number otherwise its a

prime...

TO SPEED UP THE COMPUTING WE CAN ALSO:

Rather than testing till n-1 we can test the number till

Square Root of n i.e. if n is a prime number it can always

be factored into 2 values.

REFERENCE:

See here if you want to be a mathematician ;-).

http://en.wikipedia.org/wiki/Primality_test

THE CODE:

I would assume you know how to deal with lists in c# so I

will not get into that. Just create an integer based items

list "list<int>" etc. in C# which adds digits to the list

till number n. HINT: use a for loop ...LOL!!

public void CountPrimes(list<int> c)

{

list<int> primes = c.FindAll(

delegate(int a)

for (int i = 2; i <= Math.Sqrt(a); i++)

{

if (a % i == 0)

return false; //is not a prime

return true;//is a prime

}

//list primes in a list box and get the total count

label1.Text = "Total Primes = " + Convert.ToString

(p.count);

for (int count = 2; count < p.count; count++)

{

listbox.Items.Add(Convert.ToString(p[i]));

}

}

### 6 :: How would you deal with changes being made a week or so before the ship date?

In this situation,following things must be think and tested

1) Impacted area should get tested

2) Should run all High priority test cases related area where changes has been made.

3) if gets time then run medium priority test cases

4) do sanity test around the impacted area.

### 10 :: How do speedup the project delivery without affecting the cost?

1. Identify whether its under scope or not ?

2. If its with in the scope, then there is a mistake on effort/cost estimation or in the planning.

3. Here the case.. we should delivery with in the budget or estimated cost.

4. Revise the plan and make it strictly.

5. When you revise the plan, you will identify the resource who is lead and lag.

6. Have meeting with the team mates and let them know the situation and increase the work time.

7. According to ur revise plan ( allocate the idle resource and lead resource ) start doing the work.

8. Make sure the daily review and work towards the revised plan which you made against your requirement ( Delivery with in the cost is the purpose).
