## Contribution process
## Contribution workflow
### Finding Issues to Work On
- Browse issues labeled **`good first issue`** (newcomer-friendly) or **`help wanted`** (general contributions).
- For other issues, please kindly ask before contributing to avoid duplication.
### Requirement for PRs
- All PRs, other than small documentation or typo fixes, should have a Issue assoicated. If not, please create one.
- Small, focused PRs. Keep changes minimal—one concern per PR.
- For bug fixes or features, please provide logs or screenshot after the fix is applied to help reviewers better understand the fix.
- Please include a `testing plan` section in your PR to talk about how you will test. This will save time for PR review. See `Testing Requirements` section for more details.
### Large or Complex Changes
For substantial features or architectural revisions:
- Open an Issue First: Outline your proposal, including design considerations and impact.
- Gather Feedback: Discuss with maintainers and the community to ensure alignment and avoid duplicate work
### Testing Requirements
To maintain code quality and prevent regressions, all code changes must include comprehensive tests and verifiable end-to-end (E2E) evidence.
#### Unit Tests
Please add or update unit tests for your change. Please include a summary of passed `pytest` results.
Requirements for unit tests:
- **Coverage:** Cover new features, edge cases, error conditions, and typical use cases.
- **Location:** Add or update tests under `tests/unittests/`, following existing naming conventions (e.g., `test_<module>_<feature>.py`).
- **Framework:** Use `pytest`. Tests should be:
- Fast and isolated.
- Written clearly with descriptive names.
- Free of external dependencies (use mocks or fixtures as needed).
- **Quality:** Aim for high readability and maintainability; include docstrings or comments for complex scenarios.
#### Manual End-to-End (E2E) Tests
Manual E2E tests ensure integrated flows work as intended. Your tests should cover all scenarios. Sometimes, it's also good to ensure relevant functionality is not impacted.
Depending on your change:
- **ADK Web:**
- Use the `adk web` to verify functionality.
- Capture and attach relevant screenshots demonstrating the UI/UX changes or outputs.
- Label screenshots clearly in your PR description.
- **Runner:**
- Provide the testing setup. For example, the agent definition, and the runner setup.
- Execute the `runner` tool to reproduce workflows.
- Include the command used and console output showing test results.
- Highlight sections of the log that directly relate to your change.
### Documentation
For any changes that impact user-facing documentation (guides, API reference, tutorials), please open a PR in the [adk-docs](https://github.com/google/adk-docs) repository to update relevant part before or alongside your code PR.
