ruflo-testgen

Test gap detection, coverage analysis, and automated test generation. SPARC Refinement-phase canonical owner.

Install

/plugin marketplace add ruvnet/ruflo
/plugin install ruflo-testgen@ruflo

What's Included

• Coverage Gap Detection: Identify untested code paths with prioritized gap analysis
• Coverage-Aware Routing: Route tasks to agents based on test coverage needs
• Test Generation: Automated test scaffolding for uncovered modules
• TDD Support: London School (mock-first) test patterns with agent coordination
• testgaps Worker: Background worker for continuous coverage analysis
• Integration: Works with hooks system for post-edit test suggestions

Requires

• ruflo-core plugin (provides MCP server)

Compatibility

• CLI: pinned to @claude-flow/cli v3.6 major+minor.
• Verification: bash plugins/ruflo-testgen/scripts/smoke.sh is the contract.

testgaps worker + coverage CLI surface

This plugin's two MCP/CLI surfaces:

Surface	Invocation
MCP: dispatch the testgaps worker	mcp tool call hooks_worker-dispatch --json -- '{"trigger":"testgaps"}'
CLI: coverage-gaps (table of gaps)	npx @claude-flow/cli@latest hooks coverage-gaps --format table --limit 20
CLI: coverage-route (route a task by gap)	npx @claude-flow/cli@latest hooks coverage-route --task "add auth tests"
CLI: coverage-suggest (suggest tests for a path)	npx @claude-flow/cli@latest hooks coverage-suggest --path src/

testgaps is one of 12 background workers documented in ruflo-loop-workers ADR-0001.

SPARC Refinement-phase ownership

This plugin owns the Refinement phase per ruflo-sparc ADR-0001 §"Phase-to-plugin alignment". When SPARC's sparc-refine skill runs, it composes:

1. This plugin — coverage gap detection + TDD test generation
2. ruflo-jujutsu — diff-aware refactor recommendations

Together they enforce the Refinement gate: ≥80% coverage on new code + diff risk score below threshold.

Namespace coordination

This plugin owns the test-gaps AgentDB namespace (kebab-case, follows the convention from ruflo-agentdb ADR-0001 §"Namespace convention"). Reserved namespaces (pattern, claude-memories, default) MUST NOT be shadowed.

test-gaps indexes detected gaps by file + priority + last-seen timestamp. Accessed via memory_* (namespace-routed).

Verification

bash plugins/ruflo-testgen/scripts/smoke.sh
# Expected: "10 passed, 0 failed"

Architecture Decisions

• ADR-0001 — ruflo-testgen plugin contract (testgaps-worker contract, SPARC Refinement ownership, smoke as contract)
