Add Test Coverage for AlertDialog Component
Issue Summary
Add comprehensive test coverage for AlertDialog component, ensuring correct rendering, interaction handling, and UI behavior.
Currently, AlertDialog lacks structured tests to validate dialog opening, closing, actions, and styling behavior. The expected behavior is to ensure all dialog flows work reliably under user interactions.
Problem Statement
The AlertDialog component does not have sufficient automated test coverage.
What is missing:
No validation for dialog rendering No tests for open/close interactions No verification of cancel/confirm actions No checks for applied CSS/Tailwind classes
Who is affected:
Developers maintaining UI components Users relying on confirmation dialogs Impact:
Risk of regressions in dialog behavior UI inconsistencies may go unnoticed Reduced confidence in component stability Styling issues may break silently
Proposed Solution
Add unit and interaction tests using Vitest + React Testing Library to cover:
Rendering of AlertDialog and Trigger Opening dialog via user interaction Cancel action behavior Confirm (action) behavior Proper closing of dialog Verification of custom className application
Files involved:
alert-dialog.test.tsx
Test-Driven Development Acceptance Criteria (Given-When-Then)
Scenario 1: AlertDialog renders correctly
Given the AlertDialog component is rendered When the page loads Then the trigger should be visible And dialog content should not be visible initially
Scenario 2: Dialog opens on trigger click
Given the AlertDialog is rendered When the user clicks the trigger Then the dialog content should be visible And title and action buttons should appear
Scenario 3: Cancel action closes dialog
Given the dialog is open When the user clicks the Cancel button Then the dialog should close And content should be removed from the DOM
Scenario 4: Confirm action closes dialog
Given the dialog is open When the user clicks the Action/Confirm button Then the dialog should close And no dialog content should remain visible
Scenario 5: Custom classes are applied
Given custom className props are passed When the component renders Then the classes should be applied to trigger, content, header, footer, and buttons
Test Cases
| Test ID | Test Description | Precondition | Test Steps | Expected Result | Priority |
|---|---|---|---|---|---|
| TC-001 | Render AlertDialog | Component loaded | 1. Render component | Trigger visible, dialog hidden | High |
| TC-002 | Open dialog | Component loaded | 1. Click trigger | Dialog content appears | High |
| TC-003 | Cancel action | Dialog open | 1. Click cancel | Dialog closes | High |
| TC-004 | Confirm action | Dialog open | 1. Click confirm | Dialog closes | High |
| TC-005 | Class verification | Custom classes passed | 1. Render component | Classes applied correctly | Medium |
