Abstract
A method and apparatus for performing unit testing of software modules uses a novel directed automated random testing approach that advantageously combines automated extraction of the interface of a program with its external environment using static source code parsing; automatic generation of a test driver for this interface that advantageously performs random testing to simulate the most general environment the program can operate in; and dynamic analysis of how the program behaves under random testing and automatic generation of new test inputs to direct systematically the execution along alternative program paths. Together, these techniques constitute a directed automated random testing approach (DART). With DART, testing can be performed completely automatically on any program that compiles without the need to write any test driver or harness code. During testing, DART detects standard errors such as program crashes, assertion violations, and non-termination conditions.
