To write unit tests for Cognigy Knowledge Connectors, you use the Node.js built-in test runner alongside standardized KnowledgeApi mocks to validate data flows without hitting live external vendor APIs.

The best way to mock vendor API responses in TypeScript connector tests is to implement standardized mock patterns that intercept vendor calls and assert KnowledgeApi interactions for create, upsert, and delete operations.

You do not need external testing frameworks to test Cognigy extension connectors; the approach uses the Node.js built-in test runner with node:test and node:assert for complete test scaffolding and assertion verification.

To verify create, upsert, and delete operations in a Knowledge Source test, you structure test scenarios against mock KnowledgeApi interactions and use node:assert assertions to confirm the expected data outcomes for Chunks and Sources.

This testing template targets TypeScript integration specifically, providing standardized mock patterns and type-safe test scaffolding designed for the Node.js environment required by Cognigy extension development.

Knowledge Connector unit tests fail to validate upsert flows when the KnowledgeApi mock patterns are not standardized, preventing proper verification of the create and update operations handled by the test scaffolding.
