5 Overview
This section is based on the core language defined in GB/T 26857.1-2011, which defines the behavior of TTCN-3 in an intuitive and clear manner.
meaning.
This operational semantic provides a state-oriented view on TTCN module execution. Describe different states, different TTCN-3 structures
The two ways of meaning are as follows.
a) use state information to define preconditions for structural execution;
b) Define how the execution of the structure will change a state.
Operational semantics are limited to the meaning of TTCN-3 behavior, ie functions, alternative steps, test cases, module control, and used to define test lines.
The language structure, such as send and receive operations, if-else- or while-statements. The meaning of some TTCN-3 structures can be changed by using
