@property hook: hook object providing before and after api/cli hooks

api(api_fn, api_args, expected_retval=0)

Call API function and check it’s return value. Call the appropriate hooks before and after the API call

Parameters

• api_fn – API function to call

• api_args – tuple of API function arguments

• expected_retval – Expected return value (Default value = 0)

Returns

reply from the API

assert_negative_api_retval()

Expect API failure - used with with, e.g.:

with self.vapi.assert_negative_api_retval():
    self.vapi.<api call expected to fail>

assert_zero_api_retval()

Expect API success - used with with, e.g.:

with self.vapi.assert_negative_api_retval():
    self.vapi.<api call expected to succeed>

Note

this is useful only inside another with block as success is the default expected value
