wu-sheng opened a new pull request, #145:
URL: https://github.com/apache/skywalking-infra-e2e/pull/145
## Summary
- Add `noDuplicates` template pipe function that verifies a list has no
duplicate entries (full deep equality check)
- Works with `contains`, `containsOnce`, and `range` via standard Go
template pipe syntax: `(.metrics | noDuplicates)`
- Resolves apache/skywalking#12253
## Usage
```yaml
{{- contains (.metrics | noDuplicates) }}
- name: {{ notEmpty .name }}
value: {{ notEmpty .value }}
{{- end }}
```
When duplicates exist in actual data, verification fails with an error
indicating the duplicated item.
## Changes
| File | Change |
|------|--------|
| `internal/components/verifier/funcs.go` | Add `noDuplicates` function |
| `internal/components/verifier/verifier_test.go` | 4 test cases |
| `docs/en/setup/Configuration-File.md` | Document `noDuplicates` |
## Test plan
- [x] All existing tests pass (no regression)
- [x] `noDuplicates` passes when list has no duplicates (with `contains`)
- [x] `noDuplicates` fails when list has duplicate items (with `contains`)
- [x] `noDuplicates` fails with duplicates when used with `containsOnce`
- [x] `noDuplicates` passes with `range` and no duplicates
- [x] Lint passes
