Functional Testing
Functional testing is a quality assurance process that verifies that software applications function according to specified requirements. It focuses on inputs and outputs without regard to internal code structure (black-box testing).
AI-Assisted Functional Testing
Recent advancements in Large Language Models (LLMs) and coding harnesses are transforming how functional tests are generated, executed, and evaluated.
Evaluation of Coding Harnesses for Qwen 3.8 27B
A comparative evaluation of AI coding harnesses using the Qwen 3.8 27B model highlights significant performance differences in generating and executing functional test cases.
- Tested Harnesses:
- Key Findings:
- The DeepSeek Harness outperformed the other two agents in terms of code generation accuracy and execution reliability.
- Tests focused on generating functional test scripts and validating model behavior under specific constraints.
- The evaluation demonstrated that harness selection critically impacts the efficacy of AI-driven testing workflows.

Core Principles
- Requirement-Based: Tests are derived directly from functional specifications.
- Black-Box Approach: Internal code structure is ignored; focus is on user-facing behavior.
- Validation: Ensures the system does what it is supposed to do.
