PR comment configuration - what information to show in coverage reports

comment: layout: "reach,diff,flags,tree" # Show coverage, changes, flags, and file tree behavior: default require_changes: false # Comment even if no changes require_base: false # Don't require base branch comparison require_head: true # Require current branch coverage

Define separate coverage tracking for frontend, backend, and lfx

flags: backend: paths: - src/backend/ carryforward: true # Preserve coverage data across builds if missing frontend: paths: - src/frontend/ carryforward: true # Preserve coverage data across builds if missing lfx: paths: - src/lfx/ carryforward: true # Preserve coverage data across builds if missing

Define coverage components for granular reporting

component_management: default_rules: # default rules that will be inherited by all components statuses: - type: project # in this case every component that doens't have a status defined will have a project type one target: auto branches: - "!main" individual_components: - component_id: backend_components name: "Backend Components" paths: - src/backend/base/langflow/components/** # Note: Many components excluded by .coveragerc (bundled + legacy) # This tracks coverage of remaining "core" components only

Files/directories to exclude from coverage calculations

Database migrations - infrastructure code, not business logic

• "src/backend/base/langflow/alembic/**"

Test files themselves don't need coverage

• "src/backend/tests/**"
• "src/frontend/tests/**"
• "src/frontend/test-results/**"
• "src/lfx/tests/**"

Build artifacts and dependencies

• "/pycache/"
• "**/*.pyc"
• "/node_modules/"
• "/coverage/"

Python package init files - typically just imports

• "**/init.py"

Database migrations

• "/migrations/"

LFX components - third-party integrations tracked separately

• "src/lfx/components/**"
