Boundary value analysis -: boundary values are the values which contain the lower limit and upper limit of the variable. the values within the limit will be valid and the values outside the limit will be invalid.
for example: The password should contain numbers from 1-100
A=1 , B=100
A-1,A,A+1,B-1,B,B+1
0,1,2,99,100,101
0 and 101 — invalid input
1,2,99,100 — valid input
