        const array = [];

        for (let i = 0; i <= elements.length - 2; i+=2) {

            const saleAmount = elements[i].textContent;

            if (customerName && saleAmount)
                array.push(`Customer ${customerName}: ${saleAmount}`);
        }

        return array;
    });

test('My test', async t => {
