Review AI-generated unit tests for effectiveness, coverage, assertions, negative cases, determinism, and maintainability. Output a 0-10 score, a risk level, and a must-fix checklist. Overall line coverage
must be >= 80%
; otherwise risk is at least High.
When to Use
AI-generated UT/test code review or quality evaluation
Need scoring, risk level, or must-fix checklist
Questions about coverage or assertion validity
Workflow
Confirm tests target the intended business code and key paths.
Check overall line coverage (>= 80% required).
Inspect assertions for behavioral validity; flag missing/ineffective assertions.
Verify negative/edge cases and determinism (no env/time dependency).
Score by rubric, assign risk, list must-fix items with evidence.
Scoring (0-10)
Each dimension 0-2 points. Sum = total score.
Dimension
0
1
2
Coverage
< 80%
80%+ but shallow
80%+ and meaningful
Assertion Quality
No/invalid assertions
Some weak assertions
Behavior-anchored assertions
Negative & Edge
Missing
Partial
Comprehensive
Data & Isolation
Flaky/env-dependent
Mixed
Deterministic, isolated
Maintainability
Hard to read/modify
Mixed quality
Clear structure & naming
Risk Levels
Blocker
Coverage < 80% AND key paths untested, or tests have no meaningful assertions
High
Coverage < 80% OR assertions largely ineffective
Medium
Coverage OK but weak edge cases or fragile design
Low
Minor improvements
Must-Fix Checklist
Overall line coverage >= 80%
Each test has at least one behavior-relevant assertion
Negative/exception cases exist for core logic
Tests are deterministic and repeatable
AI-Generated Test Pitfalls (Check Explicitly)
No assertions or assertions unrelated to behavior (e.g., only not-null)
Over-mocking hides real behavior
Only happy-path coverage
Tests depend on time/network/env
Missing verification of side effects

Must-fix
:
[动作 + 证据]
[动作 + 证据]
Key Evidence
:
引用具体测试用例名或覆盖率报告摘要（1-2 条）
Notes
:
最小修复建议或替代方案（1-2 行）
Rules:
覆盖率 < 80% 风险至少 High，并必须列入
Must-fix
无断言/无效断言直接提升风险级别，必须列入
Must-fix
至少 2 条证据；证据不足需说明并降分
Common Mistakes
仅报告覆盖率，不评价断言有效性
把日志输出当成断言
忽略失败路径/异常路径
Example (Concise)
Score: 5/10 (Coverage 1, Assertion 0, Negative 1, Data 2, Maintainability 1)
Risk: High
Must-fix:
Tests for
parseConfig()
contain no behavior assertions (only logs)
No negative cases for malformed input
Key Evidence:
parseConfig()
tests only assert no crash
Coverage report shows 62% lines
Notes:
Add assertions on outputs and side effects; add invalid input tests.
