Test parts organize sections and define navigation behaviors (linear/nonlinear) and submission modes. The assessment test's XML structure is automatically updated to include the new test part. ## OpenAPI ````yaml /openapi/beyond-ai/qti-api.yaml post /assessment-tests/{assessmentTestIdentifier}/test-parts openapi: 3.1.0 info: title: QTI API version: 1.0.0 description: >- A robust assessment engine implementing the QTI 3.0 specification, designed for creating, managing, and delivering educational assessments. servers: - url: https://qti.alpha-1edtech.ai/api description: Main Server security: - OAuth2: [] - MCP: [] tags: - name: Validation description: >- Validate XML strings against QTI compliant XSD files.
