- 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 | JS Source | BAT Target | Validation Focus |
|---|---|---|---|
| Decoder/Parser Support | Parser/tooling support depends on language and ecosystem. | Parser/tooling support depends on language and ecosystem. | Test representative clients and parser libraries before rollout. |
| Metadata & Structure | Encoding and line-endings can be altered during conversion. | Encoding and line-endings can be altered during conversion. | Compare metadata fields before and after conversion for drift. |
| Compression & Payload | Compression is secondary to parser and lint compatibility. | Compression is secondary to parser and lint compatibility. | Benchmark output size, quality, and processing cost at multiple settings. |
Common Failure Patterns
- Converting malformed JS files without pre-validation causes inconsistent outputs.
- Assuming all BAT 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 JS fixtures.
2. Run conversion against small, medium, and large JS samples.
3. Verify structural integrity of generated BAT 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.
