How to access history object in Jest

I have an if condition that looks like this:

if (history.state !== null && history.state.query)

      

        
        
        
      

    

The problem is, although it doesn't work in Jest, as it history

is an empty object in my tests.

What do I need to do in my tests to use the object history

? I am running this with React on a Node.js server. Not sure if this matters, but I'm using React Router as well.

Test case:

beforeEach(() => {
  window.ga = jest.fn();
  window.analytics = jest.fn();
  window.analytics.track = jest.fn();
});

it('should set up props from history state', () => {
  let location = {
    pathname: '/explore',
    query: {
      query: 'yahoo',
    },
  };

  global.history = { state: { query: 'google'} };

  const wrapper = mount(
    <LandingPage location={location} />
  );

  console.log("global.history.state: " + global.history.state); // prints null
});

      

        
        
        
      

    

Part of a component (cannot fit the whole component):

if (props.location && props.location.pathname === '/explore') {
  explorePath = true;
  skipIntro = true;
  explore = true;

  /* checks if history.state is not equal to null
   * if check passes, search query and results will appear
   */
  if (history.state !== null && history.state.query) {
    currentValue = history.state.query;
    employeeMin = history.state.eMin;
    employeeMax = history.state.eMax;
    revenueMin = history.state.rMin;
    revenueMax = history.state.rMax;
  }
} else {
  explore = skipIntro;
}
