1. ## Boundary Value Analysis

15 to 20 is the range
According to me, BV cases are 14,15,20,and 21
EQuivalence cases can be 10, 17.5, 25
Could you please update if this is correct?

Not entirely,
The BVA legitimate values are 15, 16, 19 and 20. If you need the iligitimate values as well 14 and 21 are added. It is preferred to use all these values because only then you will find faults with = instead of &gt;= and &lt; instead of &lt;=

For EQ you are correct, provided you can enter at least 1 decimal.

What is the smallest counting unit?

In your ECP you state a value can be 17.5. Can a value within the range be 15.1, or 15.01?

In BVA the +1 and -1 values around the specific boundary condition do not relate to whole numbers, they indicate the next greatest and the next least value for each specific boundary condition.

5. ## Re: Boundary Value Analysis

Just based on integral values 15 to 20

Boundary values would include:
14-16
19-21
Equivilant values would include:
17, 18
Exception values:
a whole bunch of entries but certainly
0
1
-1
15.1
-15
15-15
a
~
`
32
32 (in romanji)
Etc...

You should know why I have chosen each of these values, if you don't then you can easily research on this site or just google to learn why they were chosen. BTW, I am certainly not claiming this is an all inclusive set -- Nor am I claiming that this is the set that I would use. You have not included a number of variables that would dictate the minimal values to be tested:
language
IDE version
OS
Environment
Versions
Intended use
Localization
Architecture
Previous development errors
etc...
Just a couple of quick thoughts, your milage will vary
