Testing system

A testing system comprising:

• a test data generation module to generate test data for a program code, wherein the test data generation module module further comprises:
• a relational expression creation module configured to determine at least one relational expression corresponding to at least one parameter of the program code, wherein the at least one relational expression is determined based on at least one rule indicating a format of a valid test data for the at least one parameter;
• a boundary recognition module configured to identify one or more boundary values of the at least one parameter based on the at least one relational expression;
• and
• a solver module to generate one or more of valid test data and invalid test data for the at least one parameter based on the one or more boundary values, wherein the valid test data is a first range of values limited by the one or more boundary values and the invalid test data is a second range of values lying outside the first range of values.

A computer-readable medium having embodied thereon a computer program for executing a method comprising:

• determining at least one relational expression corresponding to at least one parameter of a program code;
• identifying one or more boundary values of the parameters based on the relational expression;
• and
• generating one or more of the valid test data and invalid test data for the at least one parameter based on the one or more boundary values, wherein the valid test data is a first range of values limited by the one or more boundary values and the invalid test data is a second range of values lying outside the first range of values.
