Can we locate the line number when react makes a warning like this "Unknown DOM property class. Did you mean className?"

There is no hint about which code made this warning.

expect(stubStyle.lineHeight).toEqual('0.5');
      ReactDOM.render(<div style={undefined} />, container);
      expect(stubStyle.display).toBe('');
      expect(stubStyle.fontFamily).toBe('');
      expect(stubStyle.lineHeight).toBe('');
    });
    it('should warn when mutating style', function() {
      spyOn(console, 'error');
      var style = {border: '1px solid black'};
      var App = React.createClass({
        getInitialState: function() {
          return {style: style};
        },
        render: function() {
          return <div style={this.state.style}>asd</div>;
        },
      });
      var stub = ReactTestUtils.renderIntoDocument(<App />);
      style.position = 'absolute';
      stub.setState({style: style});
      expect(console.error.argsForCall.length).toBe(1);
      expect(console.error.argsForCall[0][0]).toEqual(
        'Warning: `div` was passed a style object that has previously been ' +
        'mutated. Mutating `style` is deprecated. Consider cloning it ' +
        'beforehand. Check the `render` of `App`. Previous style: ' +
        '{border: "1px solid black"}. Mutated style: ' +
        '{border: "1px solid black", position: "absolute"}.'
      );
      style = {background: 'red'};
      stub = ReactTestUtils.renderIntoDocument(<App />);
