Description

Enhance Connector Functionality and Add Tests in the RiskIQ connector

Why Enhance the Connector and Implement Tests?

1. Improve Reliability: Adding tests ensures that the connector behaves as expected and prevents the introduction of new bugs during future updates.

2. Ensure Robustness: With comprehensive tests in place, we can verify edge cases and complex scenarios, making the connector more resilient to unexpected inputs or changes in upstream APIs.

3. Facilitate Maintenance: Well-tested code is easier to refactor and maintain. Future contributors will have confidence that their changes do not break existing functionality.

4. Increase User Confidence: Users will trust the connector more when they know it has been thoroughly tested and is reliable.

5. Standardize Practices: Improving the connector aligns it with best practices, including code quality, modularity, and automated testing, which are essential for long-term sustainability.
