Description

This epic aims to develop a robust test framework for the Wazuh-Engine helper functions, using YAML configurations for defining and automating the testing processes. The framework will enable systematic and scalable testing, ensuring the robustness and reliability of helper functions across various scenarios. This initiative will be implemented in several stages, each designed to incrementally build and enhance the framework's capabilities.

Objectives

• Automated Testing: Develop a framework that automatically generates tests for helper functions based on YAML-defined specifications.
• Integration with CI/CD: Integrate the testing framework with GitHub Actions to automate execution and ensure continuous validation.
• Enhanced Documentation: Automatically generate documentation for helper functions, incorporating metadata and test results to provide clear, comprehensive function descriptions.

Stages of Development

Stage 1a: YAML Configuration and Extended Test Case Generation

• Goal: Create an enhanced YAML configuration file that describes helper functions in detail, including all necessary information for generating test cases.
• Tasks:
  • Develop a tool that takes a basic YAML description of a helper function as input and generates an extended YAML file containing comprehensive test case information.
  • Define the schema for both the input and extended YAML files to ensure they capture all required attributes for comprehensive test generation.
• [x] Related issue: #23129

Stage 1b: Test Creation and Execution Tool Development

• Goal: Develop a tool that utilizes the extended YAML files generated in Stage 1a to create necessary testing assets and execute the test cases.
• Tasks:
  • Create a tool that reads the extended YAML configurations and automatically generates the testing assets needed for each helper function.
  • Implement functionality within the tool to execute each generated test case, handle exceptions, and log results.
  • Ensure the tool updates any related policy or asset information as needed to support the test execution.
• [x] Related issue: #23325

Stage 2: Integration with GitHub Actions

• Goal: Automate the execution of tests via GitHub Actions to ensure continuous validation of helper functions.
• Tasks:
  • Implement GitHub Actions workflows that trigger the execution of the automated tests generated in Stage 1b whenever code changes are pushed.
  • Configure GitHub Actions to report results back to developers, ensuring immediate feedback on the impact of changes.
• [ ] Related issue: #23424

Stage 3: Support for Unit Testing in YAML Configurations

• Goal: Enhance YAML configurations to support detailed unit testing, including expected inputs and outputs for each helper function.
• Tasks:
  • Extend the YAML schema to allow the specification of expected outputs for given inputs, facilitating end-to-end function validation.
  • Update the test generation tool to handle these specifications and validate the actual outputs against expected outcomes.

Stage 4: Automatic Documentation Generation

• Goal: Automatically generate detailed, up-to-date documentation for helper functions based on YAML configurations and test results.
• Tasks:
  • Develop a tool that extracts metadata and test information from YAML files and generates comprehensive documentation for each helper function.
  • Ensure that the documentation includes descriptions of function purposes, parameter details, usage examples, and test cases/results.

Expected Outcomes

• A robust testing framework that provides comprehensive, automated testing of Wazuh-Engine helper functions.
• Enhanced documentation that aids in understanding and utilizing helper functions effectively.
• Continuous integration and delivery processes that ensure the reliability of helper functions through systematic testing.

Notes

This epic represents a strategic enhancement to the development lifecycle of Wazuh-Engine, aiming to improve code quality, reduce bugs, and streamline function validation. Each stage of this epic will require close collaboration between developers, testers, and documentation specialists to ensure alignment and success.
