They are described by Ivar Jacobson in his book Object-Oriented Software Engineering: A Use Case Driven Approach [Jacobson, 1992]. [Read more…] about What is Use case testing in software testing?

What is State transition testing in software testing?
State transition testing is used where some aspect of the system can be described in what is called a ‘finite state machine’. This simply means that the system can be in a (finite) number of different states, and the transitions from one state to another are determined by the rules of the ‘machine’. This is the model on which the system and the tests are based. [Read more…] about What is State transition testing in software testing?
What is Decision table in software testing? How to use, examples
The techniques of equivalence partitioning and boundary value analysis are often applied to specific situations or inputs. However, if different combinations of inputs result in different actions being taken, this can be more difficult to show using equivalence partitioning and boundary value analysis, which tend to be more focused on the user interface.
The other two specification-based software testing techniques, decision tables and state transition testing are more focused on business logic or business rules. [Read more…] about What is Decision table in software testing? How to use, examples
While testing why it is important to do both equivalence partitioning and boundary value analysis?
Technically, because every boundary is in some partition, if you did only boundary value analysis you would also have tested every equivalence partition. However, this approach may cause problems if that value fails – was it only the boundary value that failed or did the whole partition fail?
Also by testing only boundaries we would probably not give the users much confidence as we are using extreme values rather than normal values. The boundaries may be more difficult (and therefore more costly) to set up as well.

What is Boundary value analysis in software testing?
Boundary value analysis (BVA) is based on testing at the boundaries between partitions. Here we have both valid boundaries (in the valid partitions) and invalid boundaries (in the invalid partitions). [Read more…] about What is Boundary value analysis in software testing?
