Black Box Testing Techniques:
1.Equivalence Partitioning.
2.Boundary Value Analysis.
3.Requirement Based Testing.
4.State Testing.
5.Decision Tables.

Advantages:
1.No programming knowledge required.
2.End user based testing.
3.Test cases can be designed as soon as functional specification is complete.

Disadvantages:
1.Difficult to identify all possible inputs.
2.Test cases will be difficult to design.
3.High probability of repeating tests already performed by programmer.
