TypeError: routingState.equals is not a function | Jest test case
This is my selector.js file:-
const makeSelectLocationState = () => {
let prevRoutingState;
let prevRoutingStateJS;
return (state) => {
const routingState = state.get('route'); // or state.route
if (!routingState.equals(prevRoutingState)) {
prevRoutingState = routingState;
prevRoutingStateJS = routingState.toJS();
}
return prevRoutingStateJS;
};
};
and the following test case I have written:-
it('makeSelectLocationState function testing', () => {
const selectLocationState = makeSelectLocationState();
const mockedState = fromJS({
route: '',
});
expect(selectLocationState(mockedState)).toEqual('');
});
While running the test case using jest I get the following error:-
TypeError: routingState.equals is not a function

The problem is here:
const routingState = state.get('route');
Sense you didn't get the routingState,possible undefined, so you will get this above error message.So check the date of routingState.
And in the test file, pass mockedState to selectLocationState
selectLocationState(mockedState)
However,makeSelectLocationState function didn't have property.Maybe change to this:
const makeSelectLocationState = (state) => {}

@Shwetank while the type of routingState is Map,and Map actually don't have equals function.You can use this:routingState.toString() === prevRoutingState.toString() or use forEach to check every item of routingState.

Perhaps you could set mockedState.route to an object that has an equals function:
const mockedState = fromJS({

});
