equivalence testing :
Test cases for input box accepting numbers between 1 and
1000 using Equivalence Partitioning:
1) One input data class with all valid inputs. Pick a single
value from range 1 to 1000 as a valid test case. If you
select other values between 1 and 1000 then result is going
to be same. So one test case for valid input data should be
sufficient.
2) Input data class with all values below lower limit. I.e.
any value below 1, as a invalid input data test case.
3) Input data with any value greater than 1000 to represent
third invalid input class.
So using equivalence partitioning you have categorized all
possible test cases into three classes. Test cases with
other values from any class should give you the same result.
We have selected one representative from every input class
to design our test cases. Test case values are selected in
such a way that largest number of attributes of equivalence
class can be exercised.
Equivalence partitioning uses fewest test cases to cover
maximum requirements.
Boundary value analysis:
It’s widely recognized that input values at the extreme ends
of input domain cause more errors in system. More
application errors occur at the boundaries of input domain.
‘Boundary value analysis’ testing technique is used to
identify errors at boundaries rather than finding those
exist in center of input domain.
Boundary value analysis is a next part of Equivalence
partitioning for designing test cases where test cases are
selected at the edges of the equivalence classes.
Test cases for input box accepting numbers between 1 and
1000 using Boundary value analysis:
1) Test cases with test data exactly as the input boundaries
of input domain i.e. values 1 and 1000 in our case.
2) Test data with values just below the extreme edges of
input domains i.e. values 0 and 999.
3) Test data with values just above the extreme edges of
input domain i.e. values 2 and 1001.
Boundary value analysis is often called as a part of stress
and negative testing

What type bugs you will find in integration testing with example?
Scenario A year ago we developed a standards compliant website for a client. Their site is very popular resulting in the client wanting to be able to track how it is being used by their users. The first part of this project is to create a Login function so that users can be identified on the website. The data supplied by users would have to be handled securely. You have been allocated this project to work on. You will be responsible for the task from start to finish and will be expected to give feedback to your manager. User expectations The client wants their users to be able to login using a page that fits in with the website design. Tom wants to access the website but doesn’t want his login information to be available to anyone else. Paul doesn’t want to login to the website because he’s not a frequent user. Task Please provide some feedback on how you would do the following:- Being the only Test Engineer on this task, what would your approach be for this requirement? Identify the key areas for testing this page. What tools if any, would you use to perform the testing, bearing in mind that the testing will be done without using an ‘automated test tool’. Provide a sample test case that could be used for testing this page, for example as a word or Excel document.
what r the measure bugs found in your project??? Give some example abt this.
Hi ALl, Can you please list out Q & A for Test Lead,which Interviewer may ask in interview for Test Lead position
how to connect your project in database?
is it possible web application make it as executable file
1)What are the QA procedures followed 2) Write test cases on a weatherreport.com web page that has only two dropdown and a submit button, Fist drop down is a countries and second is metros in the selcted countries.When proper selection si doen and submitted it shows weather report of that metro.? 3)Write test cases on Mobile Alarm Module? 4)Write test cases on Company Water Bottle?
wat if fiddler and how it is used in tesing an application. please explain with a real time scenario
Which test cases are written first: white boxes or black boxes?
I know functional test cases are derived from frs and system design specs. But are test cases for performance, database, boundary, relational integrity and other types of tests other than functional tests created from frs and system design specs as well? When are these test cases created? Are they in the same test plans alongside functional test cases or is their a different test plan that includes these test cases?
