BOUNDARY VALUE ANALYSIS
Boundary value analysis is a type of black box or specification based testing technique in which tests are performed using the boundary values.
Boundary values are validated against both the valid boundaries and invalid boundaries.
EXAMPLE:
An exam has a pass boundary at 50 percent, merit at 75 percent and distinction at 85 percent. The Valid Boundary values for this scenario will be as follows:
49,50 for pass
74,75 for merit
84,85 for distinction

USE CASE TESTING
Use Case Testing is a functional black box testing technique that helps testers to identify test scenarios that exercise the whole system on each transaction basis from start to finish. Use Cases capture the interactions between 'actors' and the 'system'.

LCSAJ TESTING
LCSAJ stands for Linear Code Sequence and Jump, a white box testing technique to identify the code coverage, which begins at the start of the program or branch and ends at the end of the program or the branch.
100% LCSAJ means 100% Statement Coverage
100% LCSAJ means 100% Branch Coverage

DECISION TABLE TESTING
Decision table testing is a software testing technique used to test system behavior for different input combinations. This is a systematic approach where the different input combinations and their corresponding system behavior are captured in a tabular form.
