BOUNDARY VALUE ANALYSIS: It is a black box testing technique which is used to reduce the no.of test cases or test data to a manageble size by focusing on the boundaries basing on the assumption that false do occur mostly at the boundaries

EQUIVALENCE PARTITION: It is a black box testing technique which is used to reduce the no.of test cases or test data to a manageble size by dividing the i/p's or o/p's or preconditions into equivalent partition that consists a set of data or treated same by application that produce the same results.

Boundary value analysis : A black box test design technique in which test cases are designed based on boundary values.

Boundary value: An input value or output value which is on the edge of an equivalence partition or at the smallest incremental distance on either side of an edge; For example the minimum or maximum value of a range.

Equivalence class partitioning: If a set of object can be linked by a relationship that is symmetric reflexive and transitive; then we can say there is equivalence class. Using this concept Equivalence partitioning method of Black box testing divides the input domain of a program into classed of data from where test case can be derived. Ideally each test case can uncover class of errors that might otherwise require many test cases to be executed before general error is occurred.
