1) Boundary Value Analysis

    In this method tester has to concentrate more on the boundaries of the input values.

   Ex: Consider any edit field which can accept values b/w 18-35.

         According to BVA method the valid inputs are:

         17,18,19,34,35 & 36 .

         If the range is 'a' to 'b'.

        Then valid i/ps are:  a-1,a,a+1,b-1,b,&b+1.

2) Equivalence pertitioning

    In this method given i/p is divided into number of equivalence classes.

    From each equivalence class one i/p value is chosed for testing.

    Ex.Consider the above ex. edit field which accepts i/p value b/w 18-35.

    From the given range of i/p value we can form  3 equivalence classes.

    i) Less than 18. 

   ii) Between 18-35.

  iii) Greater than 35.

    Take any value from three equivalence classes and test them.

    Ex.   6, 25,100

3) Error guessing.

    This depends on the tester experience, domain knowledge, & common sense.

    Ex:For the same above ex.

        i)23+,-34,5*,00,Blank,5o(Not zero,O),etc.

input domain technique.1

in this we can use bva,ecp

Boundary Value Analysis: A method useful for arriving at tests that are effective in catching defects that happen at boundaries. Most of the defects effects at the boundaries. TO get these errors we go for Boundary Value Analysis.
Let me explain with example.
Suppose we have a text box whose limits is 1 to 50. Now to these BVA for these limits the no. of conditions are 6
1 --> checking for 0 value
2 --> checking for 1 value
3 --> checking for 2 value
4 --> checking for 49 value
5 --> checking for 50 value
6 --> checking for 51 value

Now if we test for these conditions then we can say that the limit are working fine.
NOw what about the value inbetween, for this we have to go for ECP

Boundary value analysis & Equivalence class partitioning

Boundary value analysis is a methodology for designing test cases that concentrates s/w testing effort on cases near the limits of valid ranges boundary values analysis is a method which refines equivalence class partitioning. Boundary value analysis generates test cases that highlight errors better than equivalence partitioning.

as explained by satish, its absolutely correct..

i would like to add a thing to it.

there is something called "Probability Class Partitioning" this type is quite similar to error guessing..

most of the time, the probability of finding a bug is taken into consideration here in the "Probability Class Partitioning"

Ex: consider a scenario of LIC  most of the people opt for insurance at the age starting from 22 to 60 years.. so here, the probability is between 22 to 60 years and not 1 to 100years..

Test case techniques are different

1) White box testing (there are many coverage techniques in this testing type few of them are 1)decision coverage 2)statement coverage and 3)Condition coverage this depends upon the
companies requirements )
2) Black box testing (there are three types in
black box testing they are 1. BVA 2. ECP and 3. Error Guessing)
3) Incremental Testing
4) Thread testing
These are the complete test case techniques on the whole and depending upon the requirement of the company the techniques are followed .

Hope I am clear with my explanation if any wrong please revert back to me

test case techniques are two types static and dynamic. in dynamic divided into 3 types

Structure-Based
Experience-Based
Specification-Based
below one are the test case techniques

Equivalence Class Partitioning
Boundary Value Analysis
Decision Table

Here valid inputs are 1 to 7 so a=1 and b=7 and here they are telling valid inputs are a to b-(a-1) it is correct because a=1 and b-(a-1)=7 so valid
