Performance of quality assurance for a computer application development proceeds in a series of phases. Each of the phases in the QA life cycle corresponds to one or more phases in a computer application development life cycle. For example, in one embodiment, the quality assurance life cycle includes four phases—a test strategy phase, a test planning phase, a test execution phase and a rollout phase. Each phase of the QA life cycle has entrance and exit criteria. The phase can be entered when the entrance criteria have been met. When the exit criteria are met, the phase causes a gate to be closed to allow the software development life cycle to proceed to the next phase. In one embodiment, the software life cycle includes six phases—a requirements phase, a design phase, a code / unit test phase, a system test phase, a pre-production test phase and a production test phase.

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.
