@ -7,6 +7,25 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
## [Unreleased]
## [1.0.0-beta.13] - 2025-01-08
### Added
- Comprehensive local-only test framework for testing actual screenshot functionality
- SwiftUI test host application for controlled testing environment
- Screenshot validation tests including content validation and visual regression
- Performance benchmarking tests for capture operations
- Multi-display capture tests
- Test infrastructure for permission dialog testing
### Improved
- The `list` tool with `item_type: 'running_applications'` now intelligently filters its results to only show applications that have one or more windows. This provides a cleaner, more relevant list for a screenshot utility by default, hiding background processes that have no user interface.
- Test coverage with local-only tests that can validate actual capture functionality
- Test organization with new tags: `localOnly`, `screenshot`, `multiWindow`, `focus`
### Fixed
- Fixed a bug where calling the `image` tool without any arguments would incorrectly result in a "Failed to write to file" error. The tool now correctly creates and uses a temporary file, returning the capture as Base64 data as intended.
- The `list` tool's input validation is now more lenient. It will no longer error when an empty `include_window_details: []` array is provided for an `item_type` other than `application_windows`.
## [1.0.0-beta.12] - 2025-01-08
### Added

# Local-Only Tests for Peekaboo
This directory contains tests that can only be run locally (not on CI) because they require:
- Screen recording permissions
- Accessibility permissions (optional)
- A graphical environment
- User interaction (for permission dialogs)
## Test Host Application
The `TestHost` directory contains a simple SwiftUI application that serves as a controlled environment for testing screenshots and window management. The test host app:
- Displays permission status
- Shows a known window with identifiable content
- Provides various test patterns for screenshot validation
- Logs test interactions
## Running Local Tests
To run the local-only tests:
```bash
cd peekaboo-cli
./run-local-tests.sh
```
Or manually:
```bash
# Enable local tests
export RUN_LOCAL_TESTS=true
# Run all local-only tests
swift test --filter "localOnly"
# Run specific test categories
swift test --filter "screenshot"
swift test --filter "permissions"
swift test --filter "multiWindow"
```
## Test Categories
### Screenshot Validation Tests (`ScreenshotValidationTests.swift`)
- **Image content validation**: Captures windows with known content and validates the output
- **Visual regression testing**: Compares screenshots to detect visual changes
- **Format testing**: Tests PNG and JPG output formats
- **Multi-display support**: Tests capturing from multiple monitors
- **Performance benchmarks**: Measures screenshot capture performance
### Local Integration Tests (`LocalOnlyTests.swift`)
- **Test host window capture**: Captures the test host application window
- **Full screen capture**: Tests screen capture with test host visible
- **Permission dialog testing**: Tests permission request flows
- **Multi-window scenarios**: Tests capturing multiple windows
- **Focus and foreground testing**: Tests window focus behavior
## Adding New Local Tests
When adding new local-only tests:
1. Tag them with `.localOnly` to ensure they don't run on CI
2. Use the test host app for controlled testing scenarios
3. Clean up any created files/windows in test cleanup
4. Document any special requirements
Example:
```swift
@Test("My new local test", .tags(.localOnly, .screenshot))
func myLocalTest() async throws {
// Your test code here
}
```
## Permissions
The tests will automatically check for required permissions and attempt to trigger permission dialogs if needed. Grant the following permissions when prompted:
1. **Screen Recording**: Required for all screenshot functionality
2. **Accessibility**: Optional, needed for window focus operations
## CI Considerations
These tests are automatically skipped on CI because:
- The `RUN_LOCAL_TESTS` environment variable is not set
- CI environments typically lack screen recording permissions
- There's no graphical environment for window creation
The `.enabled(if:)` trait ensures these tests only run when explicitly enabled.
