StorageV1 VolumeAttachment Status Test

Progress [1/6]

Identifying an untested feature Using APISnoop

Untested Endpoints

According to following APIsnoop query, there are three VolumeAttachmentStatus endpoints that are untested.

select   endpoint,
         path,
         kind
from     testing.untested_stable_endpoint
where    eligible is true
and      endpoint ilike '%VolumeAttachmentStatus'
order by kind, endpoint
limit    20;

                endpoint                |                          path                           |       kind
----------------------------------------+---------------------------------------------------------+------------------

Test outline

Scenario: Apply changes to a VolumeAttachment Status

  Given the e2e test has created the settings for a VolumeAttachment
  When the test creates the VolumeAttachment
  Then the requested action is accepted without any error
  And the test confirms the name of the created VolumeAttachment

  Given the e2e test has created a VolumeAttachment
  When the test patches the VolumeAttachment with a label
  Then the requested action is accepted without any error
  And the test confirms that the "patched" label is found

  Given the e2e test has patched a VolumeAttachment
  When the test reads the VolumeAttachment status
  Then the requested action is accepted without any error
  And the test confirms the status of the VolumeAttachment

  Given the e2e test has read a VolumeAttachment status
  When the test patches the VolumeAttachment status
  Then the requested action is accepted without any error
  And the test confirms the new status

  Given the e2e test has patched the VolumeAttachment status
  When the test updates the VolumeAttachment status
  Then the requested action is accepted without any error
  And the test confirms the new status

  Given the e2e test has updated the VolumeAttachment status
  When the test deletes the VolumeAttachment
  Then the requested action is accepted without any error

  Given the e2e test has deleted the VolumeAttachment
  When the test lists for the VolumeAttachment with a "patched" labelSelector
  Then the requested action is accepted without any error
  And the deletion of the VolumeAttachment is confirmed

E2E Test

Using a number of existing e2e test practices a new ginkgo test has been created to provide future Conformance coverage for the 3 endpoints. The e2e logs for this test are listed below.

Verifying increase in coverage with APISnoop

Listing endpoints hit by the new e2e test

This query shows the following VolumeAttachmentStatus endpoints are hit within a short period of running this e2e test.

select distinct substring(endpoint from '\w+') AS endpoint,
                right(useragent,49) AS useragent
from  testing.audit_event
where useragent like 'e2e%should%'
  and release_date::BIGINT > round(((EXTRACT(EPOCH FROM NOW()))::numeric)*1000,0) - 20000
  and endpoint ilike '%VolumeAttachmentStatus%'
order by endpoint
limit 10;

                endpoint                |                     useragent

Final notes

If a test with these calls gets merged, test coverage will go up by 3 points

This test is also created with the goal of conformance promotion.
