# API samples heavily uses testscenarios. This allows us to use the
|
|
# same tests, with slight variations in configuration to ensure our
|
|
# various ways of calling the API are compatible. Testscenarios works
|
|
# through the class level ``scenarios`` variable. It is an array of
|
|
# tuples where the first value in each tuple is an arbitrary name for
|
|
# the scenario (should be unique), and the second item is a dictionary
|
|
# of attributes to change in the class for the test.
|
|
#
|
|
# By default we're running scenarios for 2 situations
|
|
#
|
|
# - Hitting the default /v2 endpoint with the v2.1 Compatibility stack
|
|
#
|
|
# - Hitting the default /v2.1 endpoint
|
|
#
|
|
# Things we need to set:
|
|
#
|
|
# - api_major_version - what version of the API we should be hitting
|
|
#
|
|
# - microversion - what API microversion should be used
|
|
#
|
|
# - _additional_fixtures - any additional fixtures need
|
|
#
|
|
# NOTE(sdague): if you want to build a test that only tests specific
|
|
# microversions, then replace the ``scenarios`` class variable in that
|
|
# test class with something like:
|
|
#
|
|
# [("v2_11", {'api_major_version': 'v2.1', 'microversion': '2.11'})]
