System and method for creating unit tests include: constructing a CFG representation for a computer program; utilizing the CFG to identify different potential execution paths and to identify different formulas corresponding to the different potential execution paths; parsing the source code to generate an abstract syntax tree; analyzing the computer program to determine whether it provides capability to set each of the associated variables in each formula by utilizing the abstract syntax tree; translating variables, fields, and expressions of the source code represented in each formula into decision variables; computing a solution to the list of pre-conditions from each formula to one of the potential solutions that specifies values for decision variables; selecting a formula, from the plurality of formulas, with a fewest number of associated variables; and creating a unit test, based on the data and the list of pre-conditions collected and solved.
