Within your tbody element, add four tr elements. Give the first three a class attribute set to data, and the fourth a class attribute set to total.
Your tbody element should have four tr elements.
const children = [...document.querySelector('tbody')?.children];
assert.lengthOf(children, 4);
children.forEach(child => assert.strictEqual(child?.localName, 'tr'));
Your first three tr elements should have the class attribute set to data.
const children = [...document.querySelector('tbody')?.children];
children.forEach((child, index) => {
if (index < 3) {
assert.isTrue(child?.classList?.contains('data'));
}
});
Your fourth tr element should have the class attribute set to total.
const children = [...document.querySelector('tbody')?.children];
assert.isTrue(children?.[3]?.classList?.contains('total'));
