"""API Microversion Fixture to set service microversion.
|
|
|
|
This class provides the fixture to set and reset the microversion
|
|
on service client. Service client has global variable to set the
|
|
microversion for that service API request.
|
|
For example: base_compute_client.COMPUTE_MICROVERSION
|
|
Global variable is always risky to set directly which can affect the
|
|
other test's API request also. This class provides a way to reset the
|
|
service microversion once test finish the API request.
|
|
This class can be used with useFixture: Example::
|
|
|
|
def setUp(self):
|
|
super(BaseV2ComputeTest, self).setUp()
|
|
self.useFixture(api_microversion_fixture.APIMicroversionFixture(
|
|
compute_microversion=self.compute_request_microversion))
|
|
|
|
Or you can set microversion on multiple services together::
|
|
|
|
def setUp(self):
|
|
super(ScenarioTest, self).setUp()
|
|
self.useFixture(api_microversion_fixture.APIMicroversionFixture(
|
|
compute_microversion=self.compute_request_microversion,
|
|
volume_microversion=self.volume_request_microversion))
|
|
|
|
Current supported services:
|
|
- Compute
|
|
- Volume
|
|
- Placement
