### Experimental Investigation of Effectiveness of Logical Expressions Using t-way Testing

Ranjan Bhambroo

Introduction Expressions Using t-way Testing

• Experimental Evaluation of logical expressions.

• Same idea but continued on new path.

• T – way testing instead of pair-wise testing.

• New tool for generating logical expressions.

• New tool from NIST to construct t-way test sets.

T-way Testing Expressions Using t-way Testing

• T-way

• Pair – wise = 2-way

• T-way where t=2,3,4,5,6.

• T- way more effective than pairwise.

• But test cases not enough need more test cases.

T-way Testing Expressions Using t-way Testing

• Example:

• For 15 variables total number of combinations = 215

• 215 = 32768 combinations

Tools Used Expressions Using t-way Testing

• Boolean Expression Generator – ECU( Developed by Ranjan Bhambroo)

• Advanced Combinatorial Testing System(ACTS) for constructing t-way combinatorial test sets – NIST

• Fault Evaluator – ECU

Boolean Expression Generator(New Tool) Expressions Using t-way Testing

• Generates Logical Expressions Automatically.

• Simple and user friendly interface.

• Different Modes to generate Expressions:

a)Random Number of variables.

b)Fixed Number of variables.

c)Interval of variables

• Can Control complexity of expressions.

• Allows user to save expressions in a text file.
