Feature: Comprehensive Config Parser Coverage As a developer I want to ensure the ReactiveConfigParser is thoroughly tested So that all code paths are covered and edge cases are handled Background: Given I have a reactive config parser setup Scenario: Parse configuration with merge edge cases Given I have configuration files with merge edge cases When I parse the configuration files Then the configurations should be merged handling all edge cases Scenario: Environment variable interpolation with all types Given I have configuration with environment variable patterns When I interpolate environment variables Then all variable types should be converted correctly Scenario: Template string processing Given I have configuration with template strings When I process the template strings Then template strings should be processed correctly Scenario: Route configuration validation errors Given I have invalid route configurations When I try to parse the configurations Then appropriate configuration errors should be raised Scenario: Bridge configuration edge cases Given I have bridge configurations with edge cases When I parse the bridge configurations Then bridge configurations should be parsed correctly Scenario: Configuration validation comprehensive Given I have configurations with validation issues When I validate the configurations Then all validation scenarios should be tested Scenario: Merge operation validation Given I have merge operations with various issues When I validate merge operations Then merge validation should handle all cases Scenario: Split operation validation Given I have split operations with various issues When I validate split operations Then split validation should handle all cases Scenario: Pipeline validation comprehensive Given I have pipeline configurations with issues When I validate pipeline configurations Then pipeline validation should handle all scenarios Scenario: Template instance creation Given I have template instance configurations When I create template instances Then template instances should be created correctly Scenario: Type conversion comprehensive Given I have values requiring type conversion When I perform type conversion Then all type conversions should work correctly Scenario: Config file with Jinja2 syntax detection Given I have files with Jinja2 syntax When I detect Jinja2 syntax in files Then Jinja2 files should be processed with template engine Scenario: Error handling for missing environment variables Given I have configuration with missing environment variables When I try to interpolate environment variables Then appropriate errors should be raised for missing variables Scenario: Complex nested configuration merging Given I have deeply nested configurations to merge When I merge the nested configurations Then deep merging should work correctly Scenario: Route type validation comprehensive Given I have routes with various type issues When I validate route types Then all route type validation scenarios should be covered
