--------------------------------------
Summary: Web dashboard: finish Vitest smoke-test coverage and
tighten thin specs
Key: FLINK-40600
URL: https://issues.apache.org/jira/browse/FLINK-40600
Project: Flink
Issue Type: Improvement
Components: Runtime / Web Frontend
Reporter: Martijn Visser
FLINK-40117 added Vitest specs for most of the web dashboard views, but
{{pages/application/overview}} and {{pages/application/exceptions}} still have
none. Some of the added specs also only check that the mocked data was loaded
and not what the component derived from it: the timeline spec doesn't assert
the computed vertex and subtask ranges, the job overview spec never feeds a
plan into {{ngOnInit}}, the cluster overview spec doesn't assert the derived
statistics, and {{TaskManagerService}} only has tests for {{loadManagers}} and
{{loadManager}}. The {{HumanizeDatePipe}} test for format 'B' relies on Angular
throwing for missing locale data, which an Angular upgrade could change.
We should add the two missing specs and tighten the existing ones so that they
fail when the derived values change.
