Abstract. j-POST is an integrated toolchain for property-oriented software testing. This toolchain includes a test designer, a test generator, and a test execution engine. The test generation is based on an original approach which consists of deriving a set of communicating test processes obtained both from a requirement formula (expressed in a trace-based logic) and a behavioral specification of some specific parts of the software under test. The test execution engine is then able to coordinate the execution of these test processes against a distributed Java program. j-POST was applied to check the correct deployment of a security policy for a travel management application.
