Create CoreV1 Namespace Replace Test - +1

Progress [3/6]

Identifying an untested feature Using APISnoop

According to this APIsnoop query, there are still a remaining Namespace endpoint which is untested.

SELECT
  endpoint,
  path,
  kind
  FROM testing.untested_stable_endpoint
  where eligible is true
  and endpoint ilike '%Namespace'
  order by kind, endpoint desc
  limit 10;

        endpoint        |           path            |   kind
------------------------+---------------------------+-----------
 replaceCoreV1Namespace | /api/v1/namespaces/{name} | Namespace
(1 row)

API Reference and feature documentation

Test outline

Feature: Test replace Namespace api endpoint
  • replaceCoreV1Namespace
Scenario: confirm that the replace action will apply the changes to a Namespace
  Given the e2e test has created a Namespace
  And a new label has been generated
  When the test updates the Namespace
  Then the requested action is accepted without any error
  And the newly applied label is found

E2E Test

Using a number of existing e2e test practices a new ginkgo test has been created for 1 Namespace endpoint. The e2e logs for this test are listed below.

[It] should apply an update to a Namespace
  /home/heyste/go/src/k8s.io/kubernetes/test/e2e/apimachinery/namespace.go:286
STEP: Updating Namespace "namespaces-3021"
Jun  8 11:58:02.718: INFO: Namespace "namespaces-3021" now has labels, map[string]string{"e2e-framework":"namespaces", "e2e-run":"4d96a478-b803-4cb6-abc6-eb6019b556f7", "kubernetes.io/metadata.name":"namespaces-3021", "namespaces-3021":"updated", "pod-security.kubernetes.io/enforce":"baseline"}

Verifying increase in coverage with APISnoop

Listing endpoints hit by the new e2e test

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

select distinct  endpoint, right(useragent,37) AS useragent
from testing.audit_event
where endpoint ilike '%Namespace'
and release_date::BIGINT > round(((EXTRACT(EPOCH FROM NOW()))::numeric)*1000,0) - 60000
and useragent like 'e2e%should%'
order by endpoint
limit 10;

        endpoint        |               useragent
------------------------+---------------------------------------
 createCoreV1Namespace  | should apply an update to a Namespace
 deleteCoreV1Namespace  | should apply an update to a Namespace
 readCoreV1Namespace    | should apply an update to a Namespace
 replaceCoreV1Namespace | should apply an update to a Namespace

Final notes

If a test with these calls gets merged, test coverage will go up by 1 point

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