如何用TestCafe实现window.onerror？

import { ClientFunction } from 'testcafe';

fixture `Error Handling Test`
    .page `http://example.com`;

const handleWindowError = ClientFunction((errorMessage, source, lineNumber, columnNumber, error) => {
    console.error('An error occurred:');
    console.error('Message: ' + errorMessage);
    console.error('Source: ' + source);
    console.error('Line: ' + lineNumber);
    console.error('Column: ' + columnNumber);
    console.error('Error object: ', error);
});

test('Test window.onerror', async t => {
    await t
        .execute(() => {
            window.onerror = function(errorMessage, source, lineNumber, columnNumber, error) {
                handleWindowError(errorMessage, source, lineNumber, columnNumber, error);
            };
        })
        // Perform actions that may trigger an error
        // ...
});
