EQUIVALENCE CLASS PARTITION :
THIS IS A TECHNIQUE USED IN THE BLACK BOX TESTING METHOD, USED TO REFINE THE DATA INTO VALID AND INVALID CLASSES
FOR EXAMPLE : A TEXT BOX ACCEPTS ONLY ALPHABETS THEN CHECK WITH VALID : ENTERING a-z,A-Z THEN WITH INVALID :!@&* AND SPACES,12 ETC
BOUNDARY VALUE ANALYSIS:
THIS IS A TECHNIQUE USED IN THE BLACK BOX TESTING METHOD,USE TO CHECK THROUGH RANGE TO MINIMIZE THE TIME , RATHER THAN TESTING WITH WHOLE DATA FOR EXAMPLE: (1-1000) HERE NO NEED OF TESTING RIGHT FROM START IE FROM 1 TO 100 INSTEAD, CHECK WITH THE VALUES 0,1,2,99,100,101
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
