Module test_generator 

Intelligent test case generation from parsed Perl code. Test-driven development helpers and generators. Test generator for TDD workflow support

This module provides automatic test generation for Perl code, supporting the red-green-refactor cycle of Test-Driven Development.

LSP Workflow Integration

Test generation operates within the LSP workflow: Parse → Index → Navigate → Complete → Analyze

• Parse Stage: Analyzes Perl functions/methods to determine test requirements
• Index Stage: Standardizes test patterns and identifies edge cases
• Navigate Stage: Links related test cases and maintains test dependency relationships
• Complete Stage: Generates test code using appropriate test frameworks (Test::More, Test2::V0)
• Analyze Stage: Updates test coverage metrics and integrates with workspace symbols

Essential for maintaining high-quality test coverage in enterprise Perl development systems where reliability and correctness are critical business requirements.

Usage Examples

use perl_parser::test_generator::{TestGenerator, TestFramework};
use perl_parser::{Parser, ast::Node};

let mut parser = Parser::new("sub add { my ($a, $b) = @_; return $a + $b; }");
let ast = parser.parse()?;
let generator = TestGenerator::new(TestFramework::TestMore);
let test_cases = generator.generate_tests(&ast, "sub add { my ($a, $b) = @_; return $a + $b; }");
println!("Generated {} test cases", test_cases.len());
