Implement testing infrastructure and initial unit tests (#1)

This PR introduces a comprehensive testing suite for the FreeClaw core, ensuring reliability for critical modules such as Filesystem, Memory, Agent, and Task Scheduler.

Primary Changes

1. Core Test Suite (29 Tests)

A testing architecture based on pytest has been implemented covering:

  • Agent: Resilience against malformed responses from LLM providers and Think-Act-Observe execution flow.
  • FileSystem: CRUD operations, line handling, and protection against Path Traversal attacks.
  • Memory (SQLite): Memory items CRUD, FTS5 searches, and expiration logic (TTL).
  • Task Scheduler: tasks.md parsing, duplicate task handling, and format error tolerance.
  • Configuration: Validation of precedence where environment variables correctly override JSON configurations.

2. Security and Robustness

  • SSRF Prevention: Strict validations were added to the Web module to prevent the agent from accessing private networks or localhost.
  • Time-Travel Testing: Static time.sleep calls were removed from memory tests in favor of time mocks, making the suite instantaneous and deterministic.

3. Maintenance

  • A comprehensive .gitignore file was added to prevent tracking of caches, virtual environments, local databases, and logs.
  • Cleaned up history to remove Python binary files that were accidentally tracked.

How to run tests

  1. Install development dependencies:
    pip install -e ".[test]"

  2. Run the full suite:
    PYTHONPATH=. pytest -v

Suite Results

  • Total: 29 tests PASSED.
  • Execution time: ~0.13 seconds.

Pull request overview

This PR adds a pytest-based testing setup for core FreeClaw modules (agent + tool layer), along with initial unit tests and a baseline .gitignore, aiming to prevent regressions in key behaviors like filesystem boundaries, memory persistence, task scheduling parsing, and web SSRF protections.

Changes:

  • Added a new tests/ suite with fixtures and unit tests for agent + tools (fs, memory, task scheduler, web) and config precedence.
  • Added test optional dependencies (pytest, pytest-asyncio, pytest-mock) to pyproject.toml.
  • Added a repository .gitignore for common Python/test/runtime artifacts.

I've pushed a new commit (refactor(test): apply Copilot suggestions) that fully addresses all the automated suggestions:

  1. Canonical Imports: Replaced all test imports referencing the nested physical structure (freeclaw.freeclaw.*) with the actual public package interface (freeclaw.*). This guarantees our test suite is strictly running against the same entry points used in production.
  2. Dead Code Elimination: Removed the memory_list ghost function from the memory tool tests, which was identified as deprecated/divergent code compared to the main canonical module.
  3. Hermetic SSRF Validations: Updated the URL validation assertions in test_tools_web.py to use literal public IPs (e.g., 93.184.216.34) instead of google.com. This completely decouples the test suite from external DNS resolvers, ensuring zero failures in offline or locked-down CI environments.

All 28 tests are running successfully and the regressions mentioned by Copilot have been neutralized.
