Added HKVisualizations UI Tests (#40)
# *Added HKVisualizations UI Tests* ## ♻️ Current situation & Problem *Link any open issues or pull requests (PRs) related to this PR. Please ensure that all non-trivial PRs are first tracked and discussed in an existing GitHub issue or discussion.* ## ⚙️ Release Notes *Add a bullet point list summary of the feature and possible migration guides if this is a breaking change so this section can be added to the release notes.* *Include code snippets that provide examples of the feature implemented or links to the documentation if it appends or changes the public interface.* This PR introduces a comprehensive set of UI tests to cover the HKVisualization view. The tests validate the correct rendering of UI elements, state handling, and user interactions. Test Coverage Overview: UI Rendering - Test Correct View Rendering – Ensures that the view renders correctly when data is available or unavailable. - Test Title and Labels – Verifies that chart titles, x-axis, and y-axis labels are correctly displayed. - Test Threshold Rendering – Confirms that the threshold line appears on the chart. Interaction and State Handling - Test Tap Gesture for Lollipop – Verifies that tapping a bar or point brings up the lollipop with correct data. - Test Data Accuracy in Lollipop – Validates that the correct data values appear in the lollipop. - Test Average Line Rendering – Ensures that the average line appears only when average data is available. - Test Accessibility Labels – Confirms that chart elements have accurate accessibility labels. The tests are located in HKVisualizationTests.swift. Tests run using XCTest and XCTestExtensions. Mock data is injected via launch arguments (--skipOnboarding, --mockLabData). ## 📚 Documentation *Please ensure that you properly document any additions in conformance to [Spezi Documentation Guide](https://github.com/StanfordSpezi/.github/blob/main/DOCUMENTATIONGUIDE.md).* *You can use this section to describe your solution, but we encourage contributors to document your reasoning and changes using in-line documentation.* ## ✅ Testing *Please ensure that the PR meets the testing requirements set by CodeCov and that new functionality is appropriately tested.* *This section describes important information about the tests and why some elements might not be testable.* ## 📝 Code of Conduct & Contributing Guidelines By submitting creating this pull request, you agree to follow our [Code of Conduct](https://github.com/CS342/.github/blob/main/CODE_OF_CONDUCT.md) and [Contributing Guidelines](https://github.com/CS342/.github/blob/main/CONTRIBUTING.md): - [x] I agree to follow the [Code of Conduct](https://github.com/CS342/.github/blob/main/CODE_OF_CONDUCT.md) and [Contributing Guidelines](https://github.com/CS342/.github/blob/main/CONTRIBUTING.md). --------- Co-authored-by: Sixian Du <[email protected]>
