Purushottam Sinha commented on FLINK-40035:
-------------------------------------------
Going with *Vitest* for the test framework rather than
Karma/Jest/web-test-runner.
The issue predates Angular 21: Karma is now deprecated, and *Vitest is
Angular 21's
official default runner* ({{@angular/build:unit-test}}), i.e. the "framework
supported
by Angular's build tools" the description asks for.
Why Vitest here:
* Runs in jsdom, so it fits flink-runtime-web's browserless npm CI with no
new infra
(Karma/web-test-runner would need a browser in the image).
* On Angular's roadmap, so it stays maintained through future
Angular/ng-zorro upgrades
(Karma is EOL).
* jsdom by default, with a real-browser escape hatch (Vitest browser mode via
Playwright)
for any ng-zorro view that needs it — same specs, no framework switch.
Scope: wire the Vitest test target + ng-zorro jsdom mocks, hook {{npm run
test}} into CI,
and add smoke specs for the first high-traffic views (Overview, Job List,
Exceptions).

> Key: FLINK-40035
> URL: https://issues.apache.org/jira/browse/FLINK-40035
> Project: Flink
> Issue Type: Technical Debt
> Components: Runtime / Web Frontend
> Reporter: Martijn Visser
> Priority: Major
>
> The web-dashboard ships no *.spec.ts files, so the only safety net for
> framework upgrades (e.g. the Angular 21 bump in FLINK-40028) is the lint +
> production-build gate plus manual click-through. Add smoke-level component
> specs (render + basic interaction) for the high-traffic, ng-zorro-heavy views
> so future Angular/ng-zorro bumps catch runtime regressions in CI. Requires
> wiring a test target (karma/jest, or the web-test-runner the new Angular
> builders support).
