Hi Arif,

                we didnot get any status............, can u please find out from ur HR team. or technical panel........................

is there any openings for Pune Location?

 

Hello Can i go for walikin now??

Hello Friends ,

                      Are the results for Value lab written test declared ? Any one got selected ? any one received the interview schedule or any update ? Those who have attended the walkin please do reply back.Awating ur replies.

 

 

Hii Frnds,

Actually i got a msg  on 25th from value labs saying i have cleared the written test and they have put me on hold.bt till nw dey did not communicate ny thng regarding intrvs..did nyone got the same  message ..if so plz reply

 

the process in value labs is slow in general..(bcz they try to get the best out of the appeared). Remember some projects need donkeys work...so beware. If no intimation is received they will not get it further

 

Hi Guys,

1) What is Composite Primary Key.

  1. A primary key can consist of one or more columns of a table. When two or more columns are used as a primary key, they are called a composite key. Each single column's data can be duplicated but the combination values of these columns cannot be duplicated.
  2. For example, if you have a Student table and a Course table, and one student can select many courses and one course can be selected by many students, so this is a many-to-many relationship. So you need to create the third table to define the relationship, say it's called StudentCourse. It is important to note that you only need the StudentID and CourseID in this table as a composite key. You do not need an extra identity ID column in this table to uniquely identifies each row because only having an ID column to uniquely identifies each row is not sufficient. It cannot prevent the same student selecting the same course from being inserted into this table.

2) Difference between Table and View

Views are essentially logical table-like structures populated on the fly by a given query. The results of a view query are not stored anywhere on disk and the view is recreated every time the query is executed. Materialized views are actual structures stored within the database and written to disk. They are updated based on the parameters defined when they are created.

view uses a query to pull data from the underlying tables.

A materialized view is a table on disk that contains the result set of a query.

3) Difference between ECP and BVA

If I say in one line then ECP doesn’t include the boundary values in class partitions e.g. If we have three classes of 1-20, 21-40 and 41-60 then ECP we are not including the values 1,20,21,40,41 and 60 whereas  in BVA we include them also.

 4) Difference between Testing Scenario and Test Case

Test case is a condition which is executed for expected output with predefined set of steps with known inputs. Generally a test case have

1) Precondition
2) Steps to execute
3) Input data
4) Expected output
5) Status (Pass/Fail)

Test Scenario is set of test cases. What it means, If you have to withdraw money from an ATM ma chine, then it is a scenario. But to withdraw money, you need to execute many test cases, needs to provide many inputs and you get many outputs and finally your money with receipt of transaction.

Test Scenario is 'What to be tested' and Test Case is 'How to be tested'.

5) Explain V -model

                             

    6) High Priority test cases for ATM application

 

                        1. Machine is accepting ATM card

2. Machine is rejecting expired card

3. successful entry of PIN number

4. unsuccessful operation due to enter wrong PIN number 3 times

5. successful selection of language

6. successful selection of account type

7. unsuccessful operation due to invalid account type

8. successful selection of amount to be withdraw

9. successful withdrawal.

10. Expected message due to amount is greater than day limit

11. unsuccessful withdraw operation due to lack of money in ATM

12. Expected message due to amount to withdraw is greater than possible balance.

13. unsuccessful withdraw operation due to click cancel after insert card

14. Check ATM machine is able to print receipts

15. Withdraw amount should be in the multiples of 100

7) Different DDL and DML commands

Data Definition Language (also known as DDL) is a computer language used to define data structures [ALTER  COMMENT  DROP  CREATE]


The most popular form of DML is the Structured Query Language (or SQL). This is a language used for databases, and is designed specifically for managing data in relational database management systems (or RDBMS) [UPDATE DELETE LOCK INSERT SELECT]

 9) Is functional Testing and System testing Same?

I would say ..No it’s not same.

-System testing is nothing but testing of the application as whole, where as Functional testing is nothing but testing of the application functionality.

 

-System testing is one of the phases of testing in SDLC .

For Eg in typical V model in  develeopement phase unit testing is performed, followed by integration test  and when the software is ready it is deployed to QA environment to perform "system testing ".

System testing is end to end application testing.

Functional testing is the Type of testing. It means testing the various  functionalities of the application (individual or integrated)    Other  type being Non functional.

In system testing phase both Functional and non functional testing is performed.

  1. Most people think Functional testing and System testing is same. But they differ slightly in that functional testing verifies a software by checking it against designed specification documents while system testing validates a software by checking it against the user requirements.

    10) Bug live cycle states

  1. Open
  2. Fixed
  3. Closed
  4. Reopen
  5. Obsolete

11) Tell me 3 different Software Configuration Management Tools

http://www.software-pointers.com/en-configuration-tools.html

I’ve used VSS( Visual SourceSafe from Miscrosoft) & Tortoise when I was in iGATE patni, Gandhingar. 

     12) difference between Bug,error,defect

Bug : It is found in the development environment before the product is shipped to the respective customer.

Error : It is the Deviation from actual and the expected value.

Defect : It is found in the product itself after it is shipped to the respective customer.

    13) What are the test deliverable in SDLC, when to deliver what doc?

Test cases Documents
Test Plan
Testing Strategy
Test Scripts
Test Data
Test Trace-ability Matrix
Test Results/reports
Test summary report
Install/config guides
Defect Report    
Release notes

14) Tell me the concepts present in Test plan.

Refer this link : http://rakeshhansalia.wordpress.com/2012/05/14/test-plan-preparatio...

15) What are the main issues found in Browser Comparability testing.

      Alignment issues, JS errors, Image display problems, Ajax issue

16) bug life cycle

New Bug found > QA log a bug (Open State) > DEV Fix a big  (Fixed State) > QA test it (Closed if ok or Reopen it if fails)

 17)which is test case optimization method

1)BVA 2) functional testing 3) incremental testing 4) big band

          Ans: BVA ( Boundary value Analysis)

18) difference between the delete and  truncate command

 

  1. Delete and Truncate both are logged operation. But DELETE is a logged operation on a per row basis and TRUNCATE logs the de allocation of the data pages in which the data exists. You can't rollback data in TRUNCATE but in DELETE you can rollback data. TRUNCATE removes(delete) the record permanently.
  2. You cannot TRUNCATE a table that has any foreign key
    constraints.  You will have to remove the constraints, TRUNCATE the
    table, and reapply the constraints.

19) integration testing would done after system testing

a) true b) false

Ans: False

 

20) what is static method

There are two types of methods.

  1. Instance methods are associated with an object and use the instance variables of that object. This is the default.
  2. Static methods use no instance variables of any object of the class they are defined in. If you define a method to be static, you will be given a rude message by the compiler if you try to access any instance variables. You can access static variables, but except for constants, this is unusual. Static methods typically take all they data from parameters and compute something from those parameters, with no reference to variables. This is typical of methods which do some kind of generic calculation. A good example of this are the many utility methods in the predefined Math class.

your answers are inaccurate and contradictory!
