9.4 The executable platform
A very basic but flexible platform configuration is the Executable platform configuration. This
platform is any executable program that is specified.
In order to execute test cases the system under test (SUT) need to be stimulated by the
execution environment of TPT. The API of the TPT execution environment and how the SUT will
be connected to the TPT execution environment (TPT-VM) will be described in the following
section.
In Figure 34 the flow diagram of the executable environment is shown. The execution of the
test platform starts with an initialisation phase where the input file and the output file are
opened and the data for the stimulation are assigned to the TPT-outputs and the outputs of the
SUT are assigned to the TPT-inputs. The major loop consists of the actual periodical call of the
SUT and the TPT virtual machine for each time step. The test-procedure finishes with a closing
of the data files and a memory release. The return value of the executable must be set to zero
when the execution was successful.
Please refer to the lights control example and the “tpt_vm_api.h” where the full TPT-VM-
API description can be found. Please make sure having “tptvmapi.dll” in the same folder
as the executable.
