Hi,

refer the below link..i think u will get useful info

Equivalence Partitioning Testing

any personal exp,explanation pls

BVA means we are checking Boundary values

Example: if we want to check the textbox object which accepts 4 to 10 alphabets char

In BVA we will check that object by giving 3,4,5,9,10,11 lower alphabets char.

i.e.min is 4

max 10

then we will check the object by giving boundary values as min,min-1,min+1,max,max-1,max+1

i.e 4,3,5,10,9,11

ECP means we have to check the type of the object

example:In +ve condition above example we have test the object by giving alphabets i.e. a-z char only

then object will accept the value, it will pass.

In -ve condition we will check the object by giving other than alphabets(a-z)

i.e A-Z,0-9,blank etc

thank you kiran,that kind of helps

It is done because we cant check a software for all possible values.we have to use a small subset of these to check.As it is observed that most errors occur at boundary values of ranges, so they are checked separately ( through another technique called Boundary Value Analysis)

all the values are divided into classes and it is assumed that all values in a particular class will show same behaviour ie either all will result in error or none will.so we can check only few values.
for eg. if there is some condition like 4 < var1 < 15 then if it works fine for 18, it'll also work fine with 25. Similarly, if it shows error for 3, it will most likely show error for 2 also.

Basis Path Testing enables to derive a logical complexity measure of the design.it is used to find a set of execution paths.The test cases then derived are guaranteed to execute every statement in the program/software at least once.

hope this helps!

Thank you,Akankshalal,It does help.
