             Summary: Web dashboard: finish Vitest coverage for core services and job-detail drawer
                 Key: FLINK-40601
                 URL: https://issues.apache.org/jira/browse/FLINK-40601
             Project: Flink
          Issue Type: Technical Debt
          Components: Runtime / Web Frontend
            Reporter: Purushottam Sinha


FLINK-40117 and FLINK-40600 added Vitest specs for the highest-traffic web dashboard views, but 67 of 102 testable source files (components/services/pipes/directives/guards) still have zero spec coverage, leaving core state and the job-inspection UI unverified against regressions.

Gaps:
* No specs for core services: {{job.service.ts}}, {{status.service.ts}}, {{overview.service.ts}}, {{job-manager.service.ts}}, {{config.service.ts}}.
* The entire job-detail drawer tree is untested: accumulators, backpressure, chart, detail, flamegraph, subtasks, taskmanagers, watermarks (8 files) under {{pages/job/overview/*}}.
* {{dagre.component.ts}} (job graph), {{job-chart.component.ts}}/{{.service.ts}}, {{flame-graph.component.ts}}, and {{submit.component.ts}} (job submission) have none.
* Asymmetric coverage: {{task-manager}} logs/stdout/thread-dump/profiler pages have specs, the equivalent {{job-manager}} pages do not.
* Top-level shells ({{job-detail}}, {{application-detail}}, {{job.component}}, {{application.component}}) are untested.

We should add specs for the five core services first, then the job-detail drawer tree following the FLINK-40600 pattern, then mirror the {{task-manager}} logs/stdout/thread-dump/profiler specs onto {{job-manager}}.
