In addition to the Python functions described in Functions, Exceptions, Types and Constants, the following functions are available for Unit Tests.
does Usage Engine does not include any native assert functionality, this functionality can be found in the common python libraries. Add the 9.53Python Module (2.2 Python Module and ) and use in the unit test.
| Note |

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.

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.

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.
...
| Info |
|---|
| title | Example - SkipException |
|---|
|
| Code Block |
|---|
| 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.
...
| Info |
|---|
|
| Code Block |
|---|
| 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.
| Code Block |
|---|
|
def logRemove(id) |
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.
...
| Info |
|---|
|
| Code Block |
|---|
| def test():
# Add a workflow
wfAdd('Default.test.workflow_1')
|
or | Code Block |
|---|
| def test():
# Add a workflow and specify parameter values
wfAdd('Default.test.workflow_1', {'Time Unit': 'SECONDS', 'Interval': 4})
|
|
wfDelete
Deletes a workflow.
| Code Block |
|---|
|
def wfDelete(wfName) |
...
| Info |
|---|
|
| Code Block |
|---|
| def test():
wfDelete('Default.test.workflow_1') |
|
wfExists
Returns True if the workflow exists.
...
| Info |
|---|
|
| Code Block |
|---|
| def test():
wfExists('Default.test.workflow_1') |
|
wfStart
Starts the workflow. If successful, the workflow has been started but may not yet be running.
...
| Info |
|---|
|
| Code Block |
|---|
| def test():
# Starts the workflow on the default EC
wfStart('Default.test.workflow_1') |
or | Code Block |
|---|
| def test():
# Starts the workflow on ec1
wfStart('Default.test.workflow_1', ec='ec1')
|
|
wfSetDebugMode
Sets the workflow debug mode.
...
| Info |
|---|
| title | Example - wfSetDebugMode |
|---|
|
| Code Block |
|---|
| def test():
wfSetDebugMode('Default.test.workflow_1', True)
wfStart('Default.test.workflow_1') |
or | Code Block |
|---|
| 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.
...
| Info |
|---|
| title | Example - wfIsCompleted |
|---|
|
| Code Block |
|---|
| 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.
...
| Info |
|---|
| title | Example - wfIsRunning |
|---|
|
| Code Block |
|---|
| 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.
| Code Block |
|---|
|
def wfIsAborted(wfName) |
wfAbortMessage
Returns the workflow abort message, if any.
...
| Info |
|---|
| title | Example - wfAbortMessage |
|---|
|
| Code Block |
|---|
| 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.
...
| Info |
|---|
| title | Example - Event functions |
|---|
|
| Code Block |
|---|
| 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.
...
Parameter | Type |
|---|
filter | dict[str, any] |
ttl | float |
maxSize | int |
eventBufferDestroy
Destroys the event buffer and releases any resources associated with it.
...
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.
