Passing Parameters to Tests

[wtt901]

I now have parameterized test limits:

pmeasurement=measByte(80,900) # Returns a byte count measurement, minimum=80, maximum = 900
   dynamicTestPhases=[]
   # Loop through all the dynamic test specs choosing the phase and measurement
   dynamicTestPhases.append(htf.measures(pmeasurement)(byteCountTest))
   test = htf.Test(
       htf.PhaseGroup(
           setup=[setup_phase],
           main=dynamicTestPhases
           #teardown=[td_phase]
       )
   )

. However, the test itself needs a parameter: the signal to retrieve. I have this code:

@htf.plug(dv=PlugDataVac)
def byteCountTest(test, dv):
    lic="HDR-04-1"
    test.measurements.bytes=dv.getLic(lic)
    print(f'The value is {test.measurements.bytes}.')
    if dv.getStatus():
        return htf.PhaseResult.CONTINUE
    else:
        return htf.PhaseResult.STOP

In this example, the lic is hardcoded. I need to pass in the value to get. I tried to put a name on test.measurements.bytes but that didn't work. Any ideas appreciated!

You can add args to your phases (should go after TestApi and any plugs):

@htf.plug(dv=PlugDataVac)
def byteCountTest(test, dv, lic):
    test.measurements.bytes=dv.getLic(lic)
    print(f'The value is {test.measurements.bytes}.')
    if dv.getStatus():
        return htf.PhaseResult.CONTINUE
    else:
        return htf.PhaseResult.STOP

Then "bind" the arg value to the phase descriptor using with_args:

dynamicTestPhases.append(htf.measures(pmeasurement)(byteCountTest.with_args(lic="HDR-04-1")))

That did it. Thanks!
