Command Syntax

sub-agent-test-generator [target] [options]

# Aliases
@test-gen [target] [options]
@test-generator [target] [options]
@satg [target] [options]

Parameters

target - Files or directories to generate tests for
--coverage-target - Target coverage percentage (default: 80)
--type - Test types (unit, integration, e2e, all)
--framework - Test framework (jest, phpunit, playwright, cypress)
--only-untested - Only generate for untested code
--from-flows - Generate from user flow analysis
--mock-strategy - Mocking approach (minimal, realistic, full)
--assertions - Assertion style (expect, should, assert)
--update-existing - Update existing tests
--edge-cases - Include edge case testing

Examples

# Generate missing unit tests
@test-gen src/services/ --only-untested

# Generate tests with 90% coverage target
@test-gen src/ --coverage-target 90 --type unit

# Generate E2E tests from user flows
@test-gen --type e2e --from-flows src/features/

# Update existing tests with edge cases
@test-gen src/utils/ --update-existing --edge-cases

Agent Orchestration

Stage 1: Analysis Agents (Parallel)

Agent 1: Coverage Analyzer

Analyze test coverage in [TARGET]

Tasks:
1. Coverage Metrics:
   - Line coverage
   - Branch coverage
   - Function coverage
   - Statement coverage
   - Path coverage

2. Untested Code:
   - Functions without tests
   - Uncovered branches
   - Error paths not tested
   - Edge cases missing
   - Integration gaps

3. Test Quality:
   - Assertion density
   - Mock coverage
   - Test isolation
   - Setup/teardown patterns
   - Test naming

4. Critical Paths:
   - Business logic coverage
   - Error handling coverage
   - Security function coverage
   - Data validation coverage
   - API endpoint coverage

Return:
- Coverage report by file
- Untested functions list
- Critical gap analysis
- Test quality metrics
- Priority test targets

Agent 2: Code Path Analyzer

Analyze code paths and behaviors in [TARGET]

Tasks:
1. Function Analysis:
   - Input parameters
   - Return values
   - Side effects
   - Dependencies
   - Error conditions

2. Branch Analysis:
   - Conditional branches
   - Loop variations
   - Switch cases
   - Try-catch blocks
   - Early returns

3. State Analysis:
   - State mutations
   - Class properties
   - Global state usage
   - Context dependencies
   - Lifecycle methods

4. Integration Points:
   - API calls
   - Database queries
   - File operations
   - External services
   - Event emissions

Return:
- Function behavior map
- Branch conditions
- State dependencies
- Integration points
- Test scenarios needed

Agent 3: Pattern Recognizer

Identify testing patterns and conventions in [TARGET]

Tasks:
1. Exi
