Testing ChakraWrapper Component Rendering in Apache Airflow

This test suite validates the ChakraWrapper component’s functionality in Apache Airflow’s UI, focusing on proper rendering of child components and empty wrapper states. The tests ensure the wrapper component correctly integrates with Chakra UI and maintains proper component hierarchy.

Test Coverage Overview

The test suite provides comprehensive coverage of the ChakraWrapper component’s core functionality.

Tests rendering with child components present
Validates empty wrapper rendering
Verifies DOM integration and presence

Implementation Analysis

The testing approach utilizes React Testing Library’s render method combined with Vitest for test execution. The implementation follows component testing best practices by checking both populated and empty component states, using modern React testing patterns with TypeScript integration.

Leverages React Testing Library’s getByText queries
Uses container assertions for empty state validation
Implements TypeScript for type-safe testing

Technical Details

Testing Framework: Vitest
UI Testing Library: @testing-library/react
Component Type: TypeScript React Component
Test Environment: JSDOM
Assertion Style: expect statements with DOM presence checks

Best Practices Demonstrated

The test suite exemplifies several testing best practices in React component testing.

Isolation of component rendering tests
Clear test case separation and naming
Use of describe blocks for logical grouping
Minimal test setup and clear assertions
Testing both normal and edge cases
