Integration Test & E2E Test Design/Implementation Rules

Test Types and Limits

Type	Purpose	Limit
Integration Test	Component interaction verification	3 per feature
E2E Test	Critical user journey verification	1-2 per feature

Behavior-First Principle

Observability Check (All YES = Include)

Check	Question	If NO
Observable	Can user observe the result?	Exclude
System Context	Does it require integration of multiple components?	Exclude
Automatable	Can it run stably in CI environment?	Exclude

Include/Exclude Criteria

Include: Business logic accuracy, data integrity, user-visible features, error handling Exclude: External live connections, performance metrics, implementation details, UI layout

Skeleton Specification

Required Comment Format

Each test skeleton MUST include:

AC: Original acceptance criteria text
ROI: Calculated score with Business Value and Frequency
Behavior: Trigger → Process → Observable Result format
Metadata: @category, @dependency, @complexity annotations

Implementation Rules

Behavior Verification

Step Type	Verification Target
Trigger	Reproduce in test setup (Arrange)
Process	Intermediate state or function call
Observable Result	Final output value (return value, error message, log output)

Pass Criteria: Test passes if "observable result" is verified as return value or mock call argument

Integration Test Mock Boundaries

Judgment Criteria	Mock	Actual
Part of test target?	No → Can mock	Yes → Actual required
External network communication?	Yes → Mock required	No → Actual recommended

E2E Test Execution Conditions

Execute only after all components are implemented
Do not use mocks (full system integration required)

Review Criteria

Skeleton and Implementation Consistency

Check	Failure Condition
Behavior Verification	No assertion for "observable result"
Verification Item Coverage	Listed verification items not included in assertions
Mock Boundary	Internal components mocked in integration test

Implementation Quality

Check	Failure Condition
AAA Structure	Arrange/Act/Assert separation unclear
Independence	State sharing between tests, execution order dependency
Reproducibility	Depends on date/random, results vary
Readability	Test name and verification content don't match
