所以我试图测试 onSubmit 函数是否在单击按钮时被触发 - 我这样做的方式是通过测试 onSubmit 函数的内部正在获取调用（axios post 方法）

考试

describe('RecipeSearch', () => {
    test('submit button should return post function to recipes/search/', () => {
        let mock = new MockAdapter(axios);
        userEvent.selectOptions(screen.getByRole('combobox'), 'Sweet');
        userEvent.click(screen.getByText('Search'));

        const config = {
            headers: {
                'Content-Type': 'application/json',
            },
        };
        const searchRecipes = mock.onPost(
            `${process.env.REACT_APP_API_URL}/recipes/search/`,
            { flavor_type: 'Sweet' },
            { config }
        );
        expect(searchRecipes).toHaveBeenCalled();
    });
});

错误

    expect(received).toHaveBeenCalled()

    Matcher error: received value must be a mock or spy function

    Received has type:  object
    Received has value: {"abortRequest": …
