This white paper discusses how
Reactis 1 for C, an automated
test-generation tool, may be used to find bugs in C programs.
Reactis for C consists of three primary components: Tester,
Simulator, and Validator.
Reactis Tester automatically generates test cases that stress a program,
often discovering run-time errors. The generated tests aim to maximize coverage with
respect to a number of test coverage metrics including Statement, Decision,
Condition and Modified Condition/Decision Coverage (MC/DC). Reactis
Simulator is a simulation environment which supports interactive execution and
debugging of C programs and graphical display of test coverage results.
Reactis Validator enables an engineer to formalize application
requirements (as assertions or coverage targets)
and perform an automatic check for requirement violations.
Validator performs these checks by thoroughly simulating the program
with the goal of violating assertions and covering targets.
When a runtime error or assertion failure occurs,
Validator returns a test which produces a concrete execution sequence that
leads to the error, which
greatly facilitates the diagnosis and repair of the underlying software bug.
