Feature: LangGraph Edge Cases and Missing Coverage
|
|
As a developer
|
|
I want comprehensive test coverage for LangGraph edge cases
|
|
So that all code paths are tested for robustness
|
|
|
|
Background:
|
|
Given I have imported the necessary modules
|
|
And I have a clean graph test environment
|
|
|
|
Scenario: Execute graph with different input formats
|
|
Given I have a GraphConfig with agent nodes for execution
|
|
And I have created a LangGraph instance
|
|
When I execute the graph with raw string input
|
|
Then the state should be updated with wrapped message
|
|
|
|
Scenario: Full graph execution with actual nodes
|
|
Given I have a complete GraphConfig with execution flow
|
|
And I have created a LangGraph instance
|
|
When I execute the complete graph workflow
|
|
Then the execution should complete successfully
|
|
And all nodes should be executed in order
|
|
|
|
Scenario: Test private method coverage
|
|
Given I have a GraphConfig with complex structure
|
|
And I have created a LangGraph instance
|
|
When I test missing line coverage directly
|
|
Then all private methods should be executed
|
|
|
|
Scenario: Test node executor edge cases
|
|
Given I have a GraphConfig with agent node for executor
|
|
And I have created a LangGraph instance
|
|
When I test the node executor function directly
|
|
Then the executor should handle state updates correctly
|
|
|
|
Scenario: Test parallel execution with actual tasks
|
|
Given I have a GraphConfig with parallel nodes
|
|
And I have created a LangGraph instance
|
|
When I execute parallel tasks with real operations
|
|
Then parallel execution should complete successfully
|
|
|
|
Scenario: Test visualization with complex conditions
|
|
Given I have a GraphConfig with conditional edges and labels
|
|
And I have created a LangGraph instance
|
|
When I visualize with complex edge conditions
|
|
Then the visualization should include condition labels
|
|
|
|
Scenario: Test graph state persistence
|
|
Given I have a GraphConfig with checkpointing
|
|
And I have created a LangGraph instance
|
|
When I test state persistence operations
|
|
Then state should be saved and restored correctly
|
|
|
|
Scenario: Test error handling in execution
|
|
Given I have a GraphConfig with failing nodes
|
|
And I have created a LangGraph instance
|
|
When I execute with error conditions
|
|
Then errors should be handled gracefully
|
|
|
|
Scenario: Test graph modification after creation
|
|
Given I have a basic GraphConfig
|
|
And I have created a LangGraph instance
|
|
When I modify the graph structure
|
|
Then modifications should be applied correctly
|
|
|
|
Scenario: Test node execution with dependencies
|
|
Given I have a GraphConfig with complex dependencies
|
|
And I have created a LangGraph instance
|
|
When I test node dependency resolution
|
|
Then nodes should execute in correct order
|
|
|
|
Scenario: Test stream creation and management
|
|
Given I have a GraphConfig for stream testing
|
|
And I have created a LangGraph instance
|
|
When I test stream creation and routing
|
|
Then streams should be created and routed correctly
|
|
|
|
Scenario: Test edge condition evaluation
|
|
Given I have a GraphConfig with conditional routing
|
|
And I have created a LangGraph instance
|
|
When I test edge condition evaluation directly
|
|
Then conditions should be evaluated correctly
|
|
|
|
Scenario: Test graph analysis methods
|
|
Given I have a GraphConfig with complex topology
|
|
And I have created a LangGraph instance
|
|
When I test graph analysis methods
|
|
Then topology analysis should be complete
|
|
|
|
Scenario: Test execution history tracking
|
|
Given I have a GraphConfig with multiple nodes
|
|
And I have created a LangGraph instance
|
|
When I execute nodes and track history
|
|
Then execution history should be accurate
|
|
|
|
Scenario: Test scheduler and router integration
|
|
Given I have custom scheduler and router
|
|
And I have a GraphConfig for integration testing
|
|
When I create LangGraph with custom components
|
|
Then integration should work correctly
|
|
|
|
Scenario: Test missing coverage branches
|
|
Given I have GraphConfigs for all edge cases
|
|
When I execute all missing coverage scenarios
|
|
Then coverage should reach 90% or higher
