aglinxinyuan opened a new issue, #6258:
URL: https://github.com/apache/texera/issues/6258
### Task Summary
Add `workflow-check.spec.ts` covering `checkIfWorkflowBroken`, which reports
whether any link in a workflow references an operator ID that does not exist.
## Background
`frontend/src/app/common/util/workflow-check.ts` exports one pure predicate
and has no test.
```ts
export function checkIfWorkflowBroken(workflow: Workflow): boolean {
const validOperatorIDs = new Set(workflow.content.operators.map(o =>
o.operatorID));
return workflow.content.links.some(
link => !validOperatorIDs.has(link.source.operatorID) ||
!validOperatorIDs.has(link.target.operatorID)
);
}
```
## Behavior to pin
| Scenario | Result |
| --- | --- |
| every link's `source` / `target` operatorID exists | `false` |
| a link whose `source.operatorID` is missing from the operator list |
`true` |
| a link whose `target.operatorID` is missing | `true` |
| no links | `false` |
Build a minimal `Workflow`-shaped fixture with just `content.operators`
(each with an `operatorID`) and `content.links` (each with `source.operatorID`
/ `target.operatorID`) — only the fields the function reads. Follow
`size-formatter.util.spec.ts` in `common/util/` as the style template (`ng
test`).
## Scope
- New spec: `frontend/src/app/common/util/workflow-check.spec.ts`.
- No production-code changes.
