Answer
- A Data ingestion components, transformation scripts and sensor interfaces
- D The implementation of data validation rules and robust error handling
- E Gaps through which someone could smuggle in malicious code or manipulated data
Explanation
Component testing covers data ingestion, transformation scripts and sensor interfaces using code reviews, static analysis and hardware-specific tests. It validates the transformation logic, validation rules, error handling and vulnerabilities for malware or poisoned data. External systems are checked by system integration testing, and A/B comparisons in live operation belong to testing in production.
