Fiddle: https://jsfiddle.net/69z2wepo/33980/ (check console)

For an example providing `NaN` to a css property will result in "_NaN is an invalid value for the fontSize css style property_".
Now I'm aware that there is an error in my code but I have no idea which component I should check.
I would like to have something like this: "_NaN is an invalid value for the fontSize style property. Check the render method of Header_".
I'll be happy to try to solve this if this is something we want to do.

it('should validate against multiple children props', function() {
      ReactDOM.render(<div></div>, container);
      expect(function() {
        ReactDOM.render(
          <div children="" dangerouslySetInnerHTML={{__html: ''}}></div>,
          container
        );
      }).toThrow(
        'Can only set one of `children` or `props.dangerouslySetInnerHTML`.'
      );
    });
    it('should warn about contentEditable and children', function() {
      spyOn(console, 'error');
      ReactDOM.render(
        <div contentEditable={true}><div /></div>,
        container
      );
      expect(console.error.argsForCall.length).toBe(1);
      expect(console.error.argsForCall[0][0]).toContain('contentEditable');
    });
    it('should validate against invalid styles', function() {
      ReactDOM.render(<div></div>, container);
      expect(function() {
        ReactDOM.render(<div style={1}></div>, container);
      }).toThrow(
        'The `style` prop expects a mapping from style properties to values, ' +
        'not a string. For example, style={{marginRight: spacing + \'em\'}} ' +
        'when using JSX.'
      );
    });
