# Requirements Document

## Introduction

This specification addresses the inconsistency in GitHub Actions testing across different branches (develop, release, main, hotfix) in the tree-sitter-analyzer project. The current setup causes tests to pass on develop but fail on release/main branches, leading to unnecessary version increments and violating GitFlow best practices.

## Glossary

- **CI Pipeline**: Continuous Integration automated testing and validation workflow
- **GitFlow**: A branching model that defines a strict branching structure for project development
- **Test Matrix**: A configuration that runs tests across multiple environments (OS, Python versions)
- **Quality Gates**: Automated checks that must pass before code can be merged
- **Branch Protection**: Rules that enforce quality standards before merging
- **Pre-commit Hooks**: Automated checks that run before code is committed
- **Test Coverage**: Percentage of code exercised by automated tests
- **System Dependencies**: External tools required for testing (fd, ripgrep)

## Requirements

### Requirement 1

**User Story:** As a developer, I want consistent testing across all branches, so that code passing on develop will also pass on release and main branches.

#### Acceptance Criteria

1. WHEN tests run on develop branch THEN the system SHALL execute the same test suite, quality checks, and system dependencies as release and main branches
2. WHEN tests run on release branch THEN the system SHALL execute the same test suite, quality checks, and system dependencies as develop and main branches
3. WHEN tests run on hotfix branch THEN the system SHALL execute the same test suite, quality checks, and system dependencies as develop, release, and main branches
4. WHEN tests run on main branch THEN the system SHALL execute the same test suite, quality checks, and system dependencies as develop and release branches
5. WHERE any branch runs tests THEN the system SHALL install all extras using `--all-extras` flag consistently

### Requirement 2

**User Story:** As a DevOps engineer, I want standardized quality gates across all branches, so that we maintain consistent code quality standards.

#### Acceptance Criteria

1. WHEN code is pushed to any branch THEN the system SHALL run pre-commit quality checks (mypy, black, ruff, isort, bandit)
2. WHEN quality checks execute THEN the system SHALL use identical tool versions and configurations across all branches
3. WHEN quality checks fail THEN the system SHALL prevent the workflow from proceeding to deployment
4. WHEN quality checks pass THEN the system SHALL record the results consistently across all branches
5. WHERE quality tools are configured THEN the system SHALL use the same Python version (3.11) for quality checks across all branches

### Requirement 3

**User Story:** As a release manager, I want identical test matrices across branches, so that platform-specific issues are caught early.

#### Acceptance Criteria

1. WHEN tests execute on any branch THEN the system SHALL test against the same Python versions (3.10, 3.11, 3.12, 3.13)
2. WHEN tests execute on any branch THEN the system SHALL test against the same operating systems (ubuntu-latest, windows-latest, macos-13)
3. WHEN system dependencies are installed THEN the system SHALL install fd and ripgrep consistently across all branches
4. WHEN tests run with coverage THEN the system SHALL use the same coverage configuration (ubuntu-latest, Python 3.11) across all branches
5. WHERE test markers are used THEN the system SHALL apply the same markers (`-m "not requires_ripgrep or not requires_fd"`) consistently

### Requirement 4

**User Story:** As a project maintainer, I want to follow GitFlow best practices, so that our branching strategy is predictable and reliable.

#### Acceptance Criteria

1. WHEN develop branch tests pass THEN the system SHALL ensure the same tests will pass on release branches
2. WHEN release branch is created THEN the system SHALL run comprehensive tests before allowing PyPI deployment
3. WHEN hotfix branch is created THEN the system SHALL run the same comprehensive tests as release branches
4. WHEN code merges to main THEN the system SHALL have already passed all tests in the source branch
5. WHERE branch-specific workflows exist THEN the system SHALL maintain test consistency while allowing deployment differences

### Requirement 5

**User Story:** As a developer, I want clear separation between testing and deployment, so that test failures don't cause version number increments.

#### Acceptance Criteria

1. WHEN tests fail on any branch THEN the system SHALL prevent deployment to PyPI
2. WHEN tests pass on release branch THEN the system SHALL proceed to build and deployment only after test success
3. WHEN tests pass on hotfix branch THEN the system SHALL proceed to build and deployment only after test success
4. WHEN develop branch tests pass THEN the system SHALL NOT attempt PyPI deployment
5. WHERE deployment occurs THEN the system SHALL only happen on release and hotfix branches after all tests pass

### Requirement 6

**User Story:** As a CI/CD administrator, I want reusable workflow components, so that we maintain consistency without duplication.

#### Acceptance Criteria

1. WHEN test jobs are defined THEN the system SHALL use reusable workflow components to avoid duplication
2. WHEN quality check jobs are defined THEN the system SHALL use reusable workflow components to avoid duplication
3. WHEN system dependencies are installed THEN the system SHALL use a shared installation script across all workflows
4. WHEN workflows are updated THEN the system SHALL update the shared component once to affect all branches
5. WHERE workflow reuse is implemented THEN the system SHALL maintain the same behavior as the original workflows

### Requirement 7

**User Story:** As a developer, I want comprehensive documentation of CI/CD changes, so that I understand what tests run on each branch.

#### Acceptance Criteria

1. WHEN CI/CD workflows are modified THEN the system SHALL document the changes in a migration guide
2. WHEN workflows differ between branches THEN the system SHALL document the specific differences and reasons
3. WHEN new quality gates are added THEN the system SHALL document the requirements and expected behavior
4. WHEN troubleshooting CI failures THEN the system SHALL provide clear error messages and resolution steps
5. WHERE workflow documentation exists THEN the system SHALL keep it synchronized with actual workflow implementations
