In addition to the Python functions described in Functions, Exceptions, Types and Constants, the following functions are available for Unit Tests.

does not include any native assert functionality, this functionality can be found in the common python libraries. Add the 9.53.2 Python Module and use in the unit test.

Note!

To access the Unit Test functions described below from a /wiki/spaces/DRXXE/pages/6199505 you can import the testkit module. This is useful when you write test-related helper functions.

Finalizers

addFinalizer

This function adds a finalizer function to be called at scope exit.

def addFinalizer(func, *args, **kwargs)

Parameter	Description
func	A function
*args	Positional arguments to be passed to the function
**kwargs	Keyword arguments to be passed to the function
Returns	An object with a remove() method

Example - addFinalizer

res = createResource()
addFinalizer(res.destroy)

finalizers

A Python context manager that defines an extra finalization scope. There are two pre-defined finalization scopes; one on the module level and one for each test function. These two scopes should be enough for normal use.

Example - finalizers

with finalizers:
    res = createResource()
    addFinalizer(res.destroy)
    ...
# res.destroy() is called at 'with scope' exit.

Conditional testing

SkipException

Tests can be skipped by raising the SkipException exception in the test function blocks, or the initialize function block.

class SkipException(message=None)

Parameter	Type
message	str

Example - SkipException

def initialize():
    raise SkipException('All tests are skipped')

def test():
    raise SkipException('This test is skipped')

Log functions

logSearch

Searches for entries in the System Log matching the given criteria. Returns an iterator with all matching entries.

def logSearch(fromDate=None, toDate=None, severities=None, areas=None, wfName=None, wfGroupName=None, agentName=None, userName=None, message=None)

Parameter	Type
fromDate	drdate
toDate	drdate
severities	list[str]
areas	list[str]
wfName	str
wfGroupName	str
agentName	str
userName	str
message	str

Example - logSearch

def test():
    myit = logSearch(fromDate=drdate('2021-01-26 16:00:00.0 UTC'), toDate=drdate('2021-01-30 23:59:59.0 UTC'))
	for logEntry in myit:
		print(logEntry)

logRemove

Removes the log entry with the specified id.

def logRemove(id)

Parameter	Type
id	str

Workflow functions

These functions are event driven, meaning that an event is fired when the function is called. This means that if you use wfStart and immediately call wfIsRunning after it might return false as the workflow has yet to start. It might be necessary to loop over some of these functions while waiting for the status to changed.

wfAdd

Adds a new workflow to an existing workflow template.

def wfAdd(wfName, parameters=None)

Parameter	Type
wfName	str
parameters	dict[str, any]

Example - wfAdd

def test():
     # Add a workflow
     wfAdd('Default.test.workflow_1')

or

def test(): 
    # Add a workflow and specify parameter values
    wfAdd('Default.test.workflow_1', {'Time Unit': 'SECONDS', 'Interval': 4})

wfDelete

Deletes a workflow.

def wfDelete(wfName)

Parameter	Type
wfName	str

Example - wfDelete

def test():
	wfDelete('Default.test.workflow_1')

wfExists

Returns True if the workflow exists.

def wfExists(wfName)

Parameter	Type
wfName	str

Example - wfExists

def test():
	wfExists('Default.test.workflow_1')

wfStart

Starts the workflow. If successful, the workflow has been started but may not yet be running.

def wfStart(wfName, ec=None)

Parameter	Type
wfName	str
ec	str

Example - wfStart

def test():
    # Starts the workflow on the default EC
	wfStart('Default.test.workflow_1')

or

def test():
    # Starts the workflow on ec1
	wfStart('Default.test.workflow_1', ec='ec1')

wfSetDebugMode

Sets the workflow debug mode.

Debug mode can be set before starting the workflow or after it has become running.

def wfSetDebugMode(wfName, on)

Parameter	Type
wfName	str
on	bool

Example - wfSetDebugMode

def test():
    wfSetDebugMode('Default.test.workflow_1', True)
	wfStart('Default.test.workflow_1')

or

def test():
	wfStart('Default.test.workflow_1')
	# Wait until wf is running
    wfSetDebugMode('Default.test.workflow_1', True)

wfIsCompleted

Returns True if the workflow completed.

def wfIsCompleted(wfName)

Parameter	Type
wfName	str

Example - wfIsCompleted

def test():
    wfIsCompleted('Default.test.workflow_1') # False
	wfStart('Default.test.workflow_1')
    wfIsCompleted('Default.test.workflow_1') # False
	wfStop('Default.test.workflow_1')
	# Wait a sec for the workflow to actually stop
    wfIsCompleted('Default.test.workflow_1') # True

wfIsRunning

Returns True if the workflow is running.

def wfIsRunning(wfName)

Parameter	Type
wfName	str

Example - wfIsRunning

def test():
    wfIsRunning('Default.test.workflow_1') # False
	wfStart('Default.test.workflow_1')
	# Wait for the workflow to actually start
    wfIsRunning('Default.test.workflow_1') # True
	wfStop('Default.test.workflow_1')
    wfIsRunning('Default.test.workflow_1') # False

wfIsAborted

Returns True if the workflow aborted.

def wfIsAborted(wfName)

Parameter	Type
wfName	str

wfAbortMessage

Returns the workflow abort message, if any.

def wfAbortMessage(wfName)

Parameter	Type
wfName	str

Example - wfAbortMessage

def test():
    if wfIsAborted('Default.test.workflow_1'):
    	print(wfAbortMessage('Default.test.workflow_1'))
	else:
		pass # do something

Event functions

Below is a general example for all event functions.

Our workflow ('Default.test.workflow_1') used in the example below is a simple workflow with a pulse agent connecting to an analysis agent where we debug the input.

For information on how to format the filter see: Event Types(3.0).

Example - Event functions

def test():
    # Create an event buffer for our test workflow
    eventBuffer = eventBufferCreate(filter=dict(eventName='Debug Event', workflowName='Default.test.workflow_1'), ttl=60)
    
    # Make sure we are debugging as the filter is looking for debug events
    wfSetDebugMode('Default.test.workflow_1', True)
    # Start the workflow
    wfStart('Default.test.workflow_1')
    # Wait until some events have been produced
    # and then search the buffer
    events = eventBufferSearch(eventBuffer)
    
    for x in events:
        # Print only the agent message from the event iterator
        print(x.agentMessage)
        
    # Optionally destroy the buffer
    # it will be destroyed at the end of scope otherwise
    eventBufferDestroy(eventBuffer)

eventBufferCreate

Creates an event buffer where events matching filter are stored in memory for later inspection.
Returns the event buffer to be used in calls to other event buffer functions.

def eventBufferCreate(filter=None, ttl=None, maxSize=None)

Parameter	Type
filter	dict[str, any]
ttl	float
maxSize	int

eventBufferDestroy

Destroys the event buffer and releases any resources associated with it.

def eventBufferDestroy(buffer)

Parameter	Type
buffer	object

eventBufferSearch

Searches for events in the event buffer matching filter.
Returns an iterator with all currently matching events, with most recent event first.

def eventBufferSearch(buffer, filter=None)

Parameter	Type
buffer	object
filter	dict[str, any]
