Some checks failed
Docs CI / lint-and-preview (push) Has been cancelled
- Implement `SbomIngestServiceCollectionExtensionsTests` to verify the SBOM ingestion pipeline exports snapshots correctly. - Create `SbomIngestTransformerTests` to ensure the transformation produces expected nodes and edges, including deduplication of license nodes and normalization of timestamps. - Add `SbomSnapshotExporterTests` to test the export functionality for manifest, adjacency, nodes, and edges. - Introduce `VexOverlayTransformerTests` to validate the transformation of VEX nodes and edges. - Set up project file for the test project with necessary dependencies and configurations. - Include JSON fixture files for testing purposes.
