React Jest测试

一、

 var jest = require('jest');

 jest.dontMock('../CheckboxWithLabel.js');
 describe('CheckboxWithLabel', function() {
     it('changes the text after click', function() {
         var React = require('react/addons');
         var CheckboxWithLabel = require('../CheckboxWithLabel.js');
         var TestUtils = React.addons.TestUtils;
         var checkbox = TestUtils.renderIntoDocument( < CheckboxWithLabel labelOn = "On"
             labelOff = "Off" / > );
         var label = TestUtils.findRenderedDOMComponentWithTag(checkbox, 'label');
         expect(label.getDOMNode().textContent).toEqual('Off');
         var input = TestUtils.findRenderedDOMComponentWithTag(checkbox, 'input');
         TestUtils.Simulate.change(input);
         expect(label.getDOMNode().textContent).toEqual('On');
     });
 });
