Walkthrough

This pull request introduces a new unit test file named Action.spec.tsx for the Action component, transitioning the testing framework from Jest to Vitest. It modifies the Vitest configuration to specify a setup file and updates the import source for the configuration function. Additionally, the setup file vitest.setup.ts is enhanced by importing @testing-library/jest-dom to extend the testing capabilities with custom matchers.

Changes

File Path Change Summary
src/components/AddOn/support/components/Action/Action.spec.tsx New test file added for the Action component, implementing unit tests using Vitest.
vitest.config.ts Updated import for defineConfig and added setupFiles property pointing to vitest.setup.ts.
vitest.setup.ts Added import for @testing-library/jest-dom to enhance testing capabilities with custom matchers.

Assessment against linked issues

Objective Addressed Explanation
Replace Jest-specific functions and mocks with Vitest equivalents (2474)
Ensure all tests pass after migration using npm run test:vitest (2474)
Maintain test coverage for the file as 100% after migration (2474)

Our code is tested, all feels right!
So let’s all dance, with joy we sing,
For unit tests are a wonderful thing!" 🐇✨

9-14: Consider adding more test cases for comprehensive coverage

While the basic test case is good, consider adding tests for:

  • Empty label/children
  • Long text content
  • Optional props handling (if any)

Example structure:

describe('Testing Action Component', () => {
  const defaultProps = {
    children: 'dummy children',
    label: 'dummy label',
  };

  test('renders with default props', () => {
    // Current test
  });

  test('handles empty strings', () => {
    // Test with empty strings
  });

  test('renders long content correctly', () => {
    // Test with long strings
  });
});

15-24: 🛠️ Refactor suggestion

Enhance test robustness with better queries and interaction testing

The current implementation can be improved in several ways:

  1. Use more specific queries (e.g., getByRole or getByTestId) instead of getByText
  2. Add error boundary testing
  3. Include user interaction tests if the component has any clickable elements

Example implementation:

test('should render and handle interactions correctly', () => {
  const { getByRole, getByTestId } = render(
    <Provider store={store}>
      <Action {...props} />
    </Provider>,
  );

  // Use more specific queries
  const actionElement = getByRole('button', { name: props.label });
  expect(actionElement).toBeInTheDocument();
  
  // Test interactions if applicable
  // userEvent.click(actionElement);
  // expect(...).toHaveBeenCalled();
});

Let's verify if the component has any interactive elements:

vitest.config.ts (2)

1-1: LGTM! Correct import source for Vitest configuration

The change from 'vite' to 'vitest/config' follows Vitest's recommended configuration approach.


18-18: Verify setup file and consider adding file extension

The setupFiles configuration correctly enables custom test setup for jest-dom support. However, let's verify the setup file exists and consider adding the file extension for clarity.

Consider updating the path to explicitly include the extension:

-    setupFiles: 'vitest.setup.ts',
+    setupFiles: './vitest.setup.ts',
✅ Verification successful

Setup file exists and contains jest-dom import - no changes needed

The verification confirms that:

  1. The setup file vitest.setup.ts exists in the root directory
  2. The file correctly imports @testing-library/jest-dom

The suggested path update to ./vitest.setup.ts is unnecessary since Vitest correctly resolves the current path format, and both notations are functionally equivalent in this context.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the existence of setup file and its content

# Check if the setup file exists
if [ -f "vitest.setup.ts" ]; then
    echo "Setup file exists"
    # Verify jest-dom import
    rg -l "@testing-library/jest-dom" "vitest.setup.ts"
else
    echo "Setup file not found"
fi

@palisadoes No! My University exams are ongoing now and I delegated the same to @prayanshch (well he also has exams).

I will redirect this to any other contributor

@varshith257

  1. There are 177 test.tsx files in the repo. That's too many issues to create.
  2. How about creating issues just for screens and include all the components each uses? That would be faster as it would require only 60 issues.

Yes, that makes sense
