.slice([begin[, end]]) => ShallowWrapper

Arguments

  1. begin (Number [optional]): Index from which to slice (defaults to 0). If negative, this is treated as length+begin.
  2. end (Number [optional]): Index at which to end slicing (defaults to length). If negative, this is treated as length+end.

Returns

ShallowWrapper: A new wrapper with the subset of nodes specified.

Examples

const wrapper = shallow((
  <div>
    <div className="foo bax" />
    <div className="foo bar" />
    <div className="foo baz" />
  </div>
));
expect(wrapper.find('.foo').slice(1)).to.have.length(2);
expect(wrapper.find('.foo').slice(1).at(0).hasClass('bar')).to.equal(true);
expect(wrapper.find('.foo').slice(1).at(1).hasClass('baz')).to.equal(true);
const wrapper = shallow((
  <div>
    <div className="foo bax" />
    <div className="foo bar" />
    <div className="foo baz" />
  </div>
));
expect(wrapper.find('.foo').slice(1, 2)).to.have.length(1);
expect(wrapper.find('.foo').slice(1, 2).at(0).hasClass('bar')).to.equal(true);
