Possible Bug: The deletion of global.window in the canUseDOM test could potentially affect other tests if they run concurrently or if the restoration of global.window fails. Consider using a more isolated approach for mocking or stubbing window. |
|
Redundancy: The tests for getOwnerWindow and getOwnerDocument might be redundant if these functions are simple wrappers around native DOM properties. Review if these tests add significant value or if they could be simplified. |

2 months ago @CodiumAI-Agent /ask Are there any improvements can be made to the test of "isHTMLElement"? I want to verify a test case where a node is an Element, but not instance of HTMLElement.
export const isElement = (el) => {
return (
el !== null &&
el !== undefined &&
typeof el === 'object' &&
'nodeType' in el &&
el.nodeType === Node.ELEMENT_NODE
);
};
export const isHTMLElement = (el) => {
if (!isElement(el)) {
return false;
}
const win = el.ownerDocument.defaultView ?? window;
return el instanceof win.HTMLElement;
};Are there any improvements can be made to the test of isHTMLElement? I want to verify a test case where a node is an Element, but not instance of HTMLElement.
To improve the test coverage for isHTMLElement, you can add a test case to verify a scenario where a node is an Element but not an instance of HTMLElement. This can be done by creating an SVG element, which is an instance of Element but not HTMLElement.
Here's how you can add this test case:
describe('isHTMLElement', () => {
it('should return true for a valid HTML element', () => {
const element = createMockElement('div');
expect(isHTMLElement(element)).toBe(true);
});
it('should return false for a text node', () => {
const textNode = document.createTextNode('text');
expect(isHTMLElement(textNode)).toBe(false);
});
it('should return false for non-HTML element values', () => {
expect(isHTMLElement(null)).toBe(false);
expect(isHTMLElement(undefined)).toBe(false);
expect(isHTMLElement('string')).toBe(false);
expect(isHTMLElement(123)).toBe(false);
expect(isHTMLElement(true)).toBe(false);
expect(isHTMLElement({})).toBe(false);
expect(isHTMLElement([])).toBe(false);
});
it('should return false for an SVG element', () => {
const svgElement = document.createElementNS('http://www.w3.org/2000/svg', 'svg');
expect(isHTMLElement(svgElement)).toBe(false);
});
});In this new test case, document.createElementNS is used to create an SVG element, which is an instance of Element but not HTMLElement. This ensures that the isHTMLElement function correctly identifies it as not being an HTMLElement.
