aglinxinyuan opened a new issue, #6255:
URL: https://github.com/apache/texera/issues/6255
### Task Summary
Add `panel-dock.spec.ts` covering `calculateTotalTranslate3d`, which sums
the x/y/z offsets across one or more `translate3d(...)` CSS fragments in a
string.
## Background
`frontend/src/app/common/util/panel-dock.ts` exports
`calculateTotalTranslate3d`. It finds every `translate3d(...)` fragment in the
input string and adds up their component offsets, returning a `[x, y, z]`
tuple. It is pure (regex + arithmetic) and untested.
```ts
export function calculateTotalTranslate3d(translates: string): [number,
number, number] {
// sums each translate3d(x, y, z) match; returns [0, 0, 0] when there are
none
}
```
## Behavior to pin
| Input | Result |
| --- | --- |
| `"translate3d(10px, -5px, 0px)"` | `[10, -5, 0]` |
| two concatenated `translate3d(...)` fragments | component-wise sum |
| decimal / negative px values | parsed correctly (e.g. `1.5px`, `-20px`) |
| a string with no `translate3d(...)` | `[0, 0, 0]` |
Follow `size-formatter.util.spec.ts` in `common/util/` as the style template
(plain `describe`/`it`/`expect`, run with `ng test`).
## Scope
- New spec: `frontend/src/app/common/util/panel-dock.spec.ts`.
- No production-code changes.
