Although I am aware that there might be a more efficient way using cycle/time, my main focus is to grasp the fundamentals. For some reason, my action$ stream does not appear to be functioning; I have attempted to create multiple mock doms using xs.periodic. The testing framework being used is mocha.
import 'mocha';
import {expect} from 'chai';
import xs from 'xstream';
import Stream from 'xstream';
import {mockDOMSource, DOMSource} from '@cycle/dom';
import {HTTPSource} from '@cycle/http';
import XStreamAdapter from '@cycle/xstream-adapter';
export interface Props {
displayAbs: boolean
}
export interface ISources {
DOM: DOMSource;
http: HTTPSource;
}
function testIntent(sources: ISources):Stream<Props> {
return xs.merge<Props>(
sources.DOM
.select('.absShow').events('click')
.mapTo( { displayAbs: true } ),
sources.DOM
.select('.absHide').events('click')
.mapTo( { displayAbs: false } )
).startWith( {displayAbs: false } );
}
describe( 'Test', ()=>{
describe( 'intent()', ()=>{
it('should change on click to shows and hides', () => {
let listenerGotEnd = false;
const mDOM$: Stream<DOMSource> = xs.periodic(1000).take(6).map(ii => {
if (ii % 2 == 0) {
return mockDOMSource(XStreamAdapter, {
'.absShow': {'click': xs.of({target: {}})}
})
}
else {
return mockDOMSource(XStreamAdapter, {
'.absHide': {'click': xs.of({target: {}})}
})
}
});
const action$ = mDOM$.map(mDOM => testIntent({
DOM: mDOM,
http: {} as HTTPSource,
})).flatten();
action$.addListener({
next: (x) => {
console.log("x is " + x.displayAbs);
},
error: (err) => {
console.log("error is:" + err);
throw err;
},
complete: () => { listenerGotEnd = true; }
});
expect(listenerGotEnd).to.equal(true);
});
});/* end of describe intent */
});
