Validation Testing

■
The test host should control the execution of the tests. This is necessary,
because no assumptions can be made about the target, other than that it is
capable of running VxWorks and interacting with the target server on the host
and the target’s console serial port.
Second Target Capable. The network, busTas, and rlogin tests require the use
of a second target board, the reference board. This reference board must run a
previously validated BSP.
Target Shell Capable. The target server BSP VTS rlogin test requires a
VxWorks target shell.

7.2.2 Validation Test Suite Software Architecture
Single Target
This section describes the typical BSP VTS software architecture for a single target
and for multiple targets.
Figure 7-1 shows the overall configuration for a single target.

The typical test scenario is as follows:
1. The Tcl/WTX test script runs on the UNIX /Windows host.
2. The script attaches to the target server, which uses the target server back end
communication link to communicate with the target through the target agent.
If serial communication is required, the script uses a serial line on the host (ttya
