Responsibilities
Core Responsibilities:
•
Design and implement automated testing frameworks for oracle smart contracts, covering unit tests, integration tests, and end-to-end tests.
•
Develop and execute security test cases, focusing on core scenarios such as price data feeds, off-chain data retrieval, multi-party consensus mechanisms, and resistance to Sybil attacks.
•
Simulate various on-chain and network abnormal conditions (e.g., high Gas fees, network latency, node failures) to conduct stress testing and fault tolerance testing.
•
Work closely with the development team to perform vulnerability scanning and assist in code audits before contract deployment, ensuring no critical security risks.
•
Create and maintain clear test documentation, defect reports, and quality assessment reports.
•
Participate in verifying the accuracy of oracle node data and conducting performance benchmarking.
•
Continuously follow blockchain testing tools and best practices, and introduce new testing methodologies to enhance efficiency.
