React Native Testing Library显示了使用"waitFor"的警告

Question

我用Jest和react本机测试库进行了这个测试

it('submits form on submit button press', async () => {
const onSubmit = jest.fn();
const values = { username: 'jack' };
const { getByRole } = render(
<Form initialValues={values} onSubmit={onSubmit} />,
);
const button = getByRole('button');
fireEvent.press(button);
await waitFor(() => {
expect(onSubmit).toBeCalledWith(values, expect.anything());
});
});

它通过了，但它抛出了这个警告

Warning: You seem to have overlapping act() calls, this is not supported. Be sure to await previous act() calls before making a new one.

注意：如果我删除waitFor，警告会消失，但测试失败，因为它没有立即调用onSubmit函数。

Answer 1

将Jest预设从"react-native"更改为"@testing-library/react-native"解决了问题。

Answer 2

尝试更改

await waitFor(() => {
expect(onSubmit).toBeCalledWith(values, expect.anything());
});

至

waitFor(() => {
expect(onSubmit).toBeCalledWith(values, expect.anything());
});
