- Validate source files against MIME/signature before conversion.
- Run conversion on representative fixture sizes from the sample library.
- Verify output format integrity, metadata, and playback/rendering behavior.
- Benchmark throughput and resource cost before production rollout.
Compatibility Matrix
| Aspect | HTML Source | JSON Target | Validation Focus |
|---|---|---|---|
| Decoder/Parser Support | Office and browser support is strong for mainstream document formats. | Office and browser support is strong for mainstream document formats. | Test representative clients and parser libraries before rollout. |
| Metadata & Structure | Layout and embedded object behavior can drift during conversion. | Layout and embedded object behavior can drift during conversion. | Compare metadata fields before and after conversion for drift. |
| Compression & Payload | Compression wins are moderate compared with media formats. | Compression wins are moderate compared with media formats. | Benchmark output size, quality, and processing cost at multiple settings. |
Common Failure Patterns
- Converting malformed HTML files without pre-validation causes inconsistent outputs.
- Assuming all JSON readers parse metadata identically creates production regressions.
- Skipping fixture size diversity leads to blind spots in memory and throughput behavior.
- Deploying conversion changes without rollback thresholds increases incident risk.
QA Checklist Before Rollout
1. Validate MIME/signature for incoming HTML fixtures.
2. Run conversion against small, medium, and large HTML samples.
3. Verify structural integrity of generated JSON output.
4. Confirm metadata parity (timestamps, labels, embedded fields).
5. Benchmark conversion latency and resource usage under load.
6. Document fallback path and rollback trigger thresholds.
