I am trying to generate an iron-ajax request and run a test on its response in Polymer 2.x with using the Mocha test suite.
However, when running this test I get the following error:
Cannot read property 'generateRequest' of undefined Context. at my-test.html:25

test('checking for AJAX response', () => {
let request = ajax.generateRequest();
request.completes.then(response => {
console.log(response);
})
});
});
</script>

How can I make an AJAX request and handle the response in this framework?
I would advice to use fetch for this. It also will send an ajax call and is native to your browser.

}).then(res => {
assert.equal(res.status, 200)
return res.json()
})
.finally(res=>{
console.log(res)
done()//async test needs to tell when done
})
});
});
