1 Test Case writing questions:
10 test cases for entering 3 values representing
sides of a triangle and the program giving output as scalene, isosceles or
equilateral (10 Marks)
Test cases:
Assume 3 sides of the triangle has A, B, and C
S.No.  Test case Name  Description  Expected Result 
1  Check Scalene triangle  Enter input as A=8, B=5 and C=7  Output should be scalene triangle 
2  Check Scalene triangle  Enter input as A=200, B=400 and C=900  Output should be scalene triangle 
3  Check isosceles triangle  Enter input as A=8, B=10 and C=10  Output should be isosceles triangle 
4  Check isosceles triangle  Enter input as A=800, B=700 and C=700  Output should be isosceles triangle 
5  Check equilateral triangle  Enter input as A=15, B=15 and C=15  Output should be equilateral triangle 
6  Check equilateral triangle  Enter input as A=190, B=190 and C=190  Output should be equilateral triangle 
7  Check Negative values  Enter input as A= 6, B=15 and C=14  Error message should be displayed 
8  Check Negative values  Enter input as A= 6, B=15 and C=15  Error message should be displayed 
9  Check Negative values  Enter input as A= 6, B=16 and C=15  Error message should be displayed 
10  Check Zero values  Enter input as A= 6, B=16 and C=0  Error message should be displayed 
We can write so many test cases like above. We can have many combinations for all the above test cases.

1 Ques on weather Dev should do the testing or not. Give 3 reason on favour and 2
against it. (5 Marks)
Pros:
1. Developers should test the code they write. So that they can make sure their code is working as expected. This is called as Unit testing. They are technically sound
2. Developer has good knowledge on coding/programming and they know where programs generally give errors. They can find it very easily.
3. They have complete knowledge on the unit/piece of code they have developed. It's very easy for them to catch the errors in short period of time
Cons:
4. They may not have complete knowledge on the application/product they are developing. i.e. lack of domain knowledge
5. They don't have the testing knowledge to perform effective testing. Only testers know different methodologies in testing a application or product.
6. Personal confidence on the code they developed and they may not test all functionalities completely
1 Question diff between priority of a bug and severity of a bug. Give example of
one case where priority is high but severity is low and one case where severity is
high bur priority is low
Defect Severity determines the defect's effect on the application where as Defect Priority determines the defect urgency of repair. Severity is given by Testers and Priority by Developers
Example:
Low Severity & High Priority : If there is a spelling mistake or content issue on the homepage of a website which has daily hits of lakhs. In this case, though this fault is not affecting the website or other functionalities but considering the status and popularity of the website in the competitive market it is a high priority fault
High Severity & Low Priority : For example an application which generates some banking related reports weekly, monthly, quarterly & yearly by doing some calculations. If there is a fault while calculating yearly report. This is a high severity fault but low priority because this fault can be fixed in the next release as a change request.
1 Question on a program that calculates P=R/I where R, I are integer inputs and P
a floating point output. Write 10 test cases for this  5 Marks.
S.No.  Test case Name  Description  Expected Result 
1  Check output as float  Enter input as R=3 and I=2  Output should be a floating point number. P must be equal to 1.5 
2  Check output as Integer  Enter input as R=4 and I=4  Output should not be a floating point number. P must be equal to 1 
3  Check output as minus number  Enter input as R=8 and I=2  Output should not be a floating point number. P must be equal to 4 
4  Check output as minus number  Enter input as R=8 and I=2  Output should not be a floating point number. P must be equal to 6 
5  Check output as float  Enter input as R=1 and I=25  Output should be a floating point number. P must be equal to 0.04 
6  Check output as float  Enter input as R=100 and I=300  Output should be a floating point number. P must be equal to 0.33333333333333 
7  Check output as a zero  Enter input as R=100 and I=100  Output should not be a floating point number. P must be equal to 0 
8  Check output as a zero  Enter input as R=200 and I=200  Output should not be a floating point number. P must be equal to 0 
9  Check output as Integer  Enter input as R=900 and I=900  Output should not be a floating point number. P must be equal to 1 
10  Check output as Integer  Enter input as R=878686775 and I=6778887  Output should not be a floating point number. 




Like above we can have so many combinations of test cases. Testing is a never ending task. 100% testing is not at all possible on any application or product.
