這就是我正在覆蓋的功能，但是仍然抱怨我沒有覆蓋之前的第4行。npm run coverageexport const CardContainer = ({ index, icon, copy, click }) => (    <BlankCard variant="light" title={copy}>{icon}<p>{copy}</p>        {click && <a className="tile-learn-more" id={`tile-id-${index}`} onClick={() => click(index)}>Learn More</a>}    </BlankCard>);有問題的行：{click && <a className="tile-learn-more" id={`tile-id-${index}`} onClick={() => click(index)}>Learn More</a>}describe('CardContainer component', () => {    it('will contain BlankCard component', () => {        const props = { icon: 'icon', copy: 'foo' };        const wrapperBlankCard = shallow(<CardContainer {...props} />);        const blankCard = wrapperBlankCard.find('BlankCard');        expect(blankCard).toHaveLength(1);        expect(blankCard.at(0).prop('variant')).toEqual('light');        expect(blankCard.at(0).prop('title')).toEqual('foo');    });    it('will contain a Learn More link if click contains a function', () => {        const mockOnClick = jest.fn();        const props = { index: 1, icon: 'icon', copy: 'foo', click: mockOnClick };        const wrapper = shallow(<CardContainer {...props} />);        const learnMore = wrapper.find('.tile-learn-more');        expect(learnMore).toEqual({});        expect(learnMore.prop('id')).toEqual('tile-id-1');        expect(learnMore.contains('Learn More'));        expect(learnMore.prop('onClick')).toEqual(expect.any(Function));    });    it('will not contain a Learn More link if click is undefined', () => {        const props = { icon: 'icon', copy: 'foo', click: null };        const wrapper = shallow(<CardContainer {...props} />);        expect(wrapper.find('.tile-learn-more')).toEqual({});    });});我正在測試點擊道具的不同狀態，但是到目前為止還無法覆蓋該行，這里有任何想法嗎？
