.containsAllMatchingElements(nodes) => Boolean

Returns whether or not one of the given react elements are all matching one element in the render tree. It will determine if an element in the wrapper looks like one of the expected element by checking if all props of the expected element are present on the wrappers element and equals to each other.

Arguments

1. nodes (Array<ReactElement>): The array of nodes whose presence you are detecting in the current instance's render tree.

Returns

Boolean: whether or not the current wrapper has nodes anywhere in its render tree that looks like the nodes passed in.

Example

const wrapper = mount(
  <div>
    <span className="foo">Hello</span>
    <div style={{ fontSize: 13 }}>Goodbye</div>
    <span>Again</span>
  </div>
);

expect(wrapper.containsAllMatchingElements([
  <span>Hello</span>,
  <div>Goodbye</div>,
])).to.equal(true);

Common Gotchas

• .containsAllMatchingElements() expects an array of ReactElement, not a selector (like many other methods). Make sure that when you are calling it you are calling it with an array of ReactElement or a JSX expression.
• Keep in mind that this method determines mathcing based on the matching of the node's children as well.
