Usage

The following tests are all passing:

class TestComponent extends React.Component {}

// equalJSX
expect(<div />).toEqualJSX(<div />);
expect(<TestComponent />).toEqualJSX(<TestComponent />);

expect(<div />).not.toEqualJSX(<span />);
expect(<TestComponent />).not.toEqualJSX(<span />);

// includeJSX
expect(<div><span>Hello World!</span></div>).toIncludeJSX(<span>Hello World!</span>);
expect(<TestComponent />).toIncludeJSX(<SomeSubComponent />); // assuming <SomeSubComponent /> is rendered by TestComponent's render

expect(<div><span>Hello World!</span></div>).not.toIncludeJSX(<span>Hello World!</span>);
expect(<TestComponent />).not.toIncludeJSX(<SomeSubComponent />); // assuming <SomeSubComponent /> is not rendered by TestComponent's render
