Question

我有以下React组件：

read()

我还有一个测试文件，用于检查uart0_filestream = open("/dev/ttyUSB0", O_RDWR | O_NOCTTY | O_NDELAY);功能，效果很好：

const titleText = translate('header.about');

const About = ({onClose}) => (
  <div>
    <ModalHeader title={titleText} onClose={onClose} />
    <Content />
  </div>
);

但是，运行测试时，我在终端中收到以下警告：

onClose

仅在运行测试时，我才在浏览器中未收到警告。虽然这只是一个警告，但我宁愿解决此问题。

有什么方法可以给const spy = sinon.spy(); const wrapper = shallow(<About onClose={spy} />); // I also tried "mount()" ... assert.equal(spy.callCount, 1, 'onClose was called exactly once');赋予模拟值？我只对模拟局部变量的可能解决方案感兴趣（即本示例中的Warning: Failed prop type: The prop `title` is marked as required in `ModalHeader`, but its value is `undefined`）。

Answer 1

使用笑话，您可以像这样模拟翻译包：

// this will mock the translate package
jest.mock('translate', () => () => 'some test title');

const spy = sinon.spy();
const wrapper = shallow(<About onClose={spy} />);

...

assert.equal(spy.callCount, 1, 'onClose was called exactly once');

Answer 2

TcpClient

酶-模拟非实例变量
