Feature: DecompositionService uncovered code path coverage
|
|
As a developer
|
|
I want to exercise the uncovered branches in decomposition_service.py
|
|
So that clustering fallback chains and decision recording edge cases are tested
|
|
|
|
Background:
|
|
Given a fresh decomposition service instance
|
|
|
|
# --- Lines 236-239: Language clustering fallback ---
|
|
# When cluster_by_directory returns a single cluster, the service
|
|
# should fall through to cluster_by_language.
|
|
|
|
Scenario: Falls back to language clustering when directory clustering yields one cluster
|
|
Given a file set that directory-clusters into one group but language-clusters into many
|
|
When I run decomposition on those files
|
|
Then at least one node should use the language clustering strategy
|
|
|
|
# --- Lines 242-245: Size clustering fallback ---
|
|
# When both directory and language clustering return a single cluster,
|
|
# the service should fall through to cluster_by_size.
|
|
|
|
Scenario: Falls back to size clustering when directory and language clustering both yield one cluster
|
|
Given a file set where directory and language clustering each yield one group
|
|
When I run decomposition on those files
|
|
Then at least one node should use the size clustering strategy
|
|
|
|
# --- Lines 249-264: Complete fallback with warning ---
|
|
# When ALL clustering strategies produce zero clusters, the service
|
|
# emits a warning log and creates a single FALLBACK node.
|
|
|
|
Scenario: Creates fallback node with warning when all clustering strategies return empty
|
|
Given a file set where all clustering strategies return empty lists
|
|
When I run decomposition on those files
|
|
Then the result should contain a fallback strategy node
|
|
And a decomposition fallback warning should have been logged
|
|
|
|
# --- Line 320: record_decisions early return when decision_service is None ---
|
|
|
|
Scenario: record_decisions returns immediately when no decision service is injected
|
|
Given a decomposition service without a decision service
|
|
And a trivial decomposition result
|
|
When I call record_decisions with plan id "plan-00001"
|
|
Then no exception should be raised from record_decisions
|
|
|
|
# --- Combined: language fallback produces correct strategy label ---
|
|
|
|
Scenario: Language fallback strategy label appears in result metrics
|
|
Given a file set that directory-clusters into one group but language-clusters into many
|
|
When I run decomposition on those files and collect metrics
|
|
Then the result total_nodes metric should be present
|
|
And the result leaf_nodes metric should be present
|
|
|
|
# --- Combined: size fallback with deep recursion is bounded by max_depth ---
|
|
|
|
Scenario: Size clustering fallback respects max_depth limit
|
|
Given a file set where directory and language clustering each yield one group
|
|
When I run decomposition with max_depth 1 on those files
|
|
Then the result max_depth_reached should be at most 1
