Introduction
The CDB Simulated Components are a quick way to make a component available for development and testing. They could be used to prototype basic functionality and to mock-up components in order to prepare module tests which need to interact with other components.
Preparations
Create a module for the tests that are going to be performed:
...
| Code Block |
|---|
|
> cd test
> make all |
Simulated Component
The simulation code needs to be put in the CDB:
| Code Block |
|---|
| language | xml |
|---|
| title | sim_comp/test/CDB/alma/simulated/MOUNT/MOUNT.xml |
|---|
| linenumbers | true |
|---|
| collapse | true |
|---|
|
<SimulatedComponent xmlns="urn:schemas-cosylab-com:SimulatedComponent:1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<pythonImports>
from acstime import Duration
</pythonImports>
<initialize>
logger=parameters[0].getLogger()
logger.logInfo("Component initialized!")
</initialize>
<cleanUp>
print('Simulated component cleaning up')
</cleanUp>
<_corbaMethod Name="objfix" Timeout="0">
print("\nobjfix called with params ", parameters, "\n")
</_corbaMethod>
</SimulatedComponent> |
Client
A simple client could be prepared:
| Code Block |
|---|
| language | py |
|---|
| title | sim_comp/test/client.py |
|---|
| linenumbers | true |
|---|
| collapse | true |
|---|
|
from Acspy.Clients.SimpleClient import PySimpleClient
client = PySimpleClient()
m = client.getComponent("MOUNT")
m.objfix(3,6) |
Executing
Start ACS:
| Code Block |
|---|
| language | bash |
|---|
| title | Console 1 |
|---|
|
> cd sim_comp
> export ACS_CDB=$PWD/test
> export IDL_PATH="-I$PWD/idl $IDLPATH"
> acsStart |
...
