Design and Implementation of Test Executor for Concurrent TTCN

The method of designing a common-used concurrent TTCN test executor is proposed in this paper. When testing an implementation of concurrent protocol, the problem of executing concurrent test cases by FIFO scheduling algorithm is solved and the PTI (packet transmitting interface) part based on the abstract I/O queue theory is proposed. The PTI part offers the test executor the independency on implementations of a given protocol. What's more, the test executor provides a visual interface to trace the executing of test cases, which makes the locating of faults easier. Banding with corresponding PTI part, the test executor can start a testing. Now it is already
