The bigger applications like web servers e.g. Apache, databases e.g. mysql, and application servers e.g. Tomcat are required to be customizable to adapt to particular runtime contexts and application scenarios. One way to support software customization is to provide configuration options through which the behavior of the system can be controlled. But the configuration spaces of modern software systems are too large to test exhaustively. The proposed method called traditional combinatorial interaction testing which samples the covering arrays and the test cases to make the highly configured application or system. In the combinatorial interaction testing generally we generate configuration options and then we apply test cases for each configuration options. That causes masking effect or skipping of the some reliable configuration options. The obtained system is towards to highly configurable system which uses traditional combinatorial Interaction Testing. Traditional Combinatorial Interaction Testing generates test cases with configuration options and uses test case specific constraints and seeding which avoids the masking effect.
