My goal is to verify the correct scroll position in the browser using NightwatchJS and Selenium. Below is the command I am using in Nightwatch:
assertScrollPosition(testValue) {
this.api.execute(() => {
const offsetValue = window.pageYOffset;
return offsetValue;
}, [], (result) => {
console.log(result);
this.assert.equal(
testValue,
result.value,
);
});
},
Initially, everything was working fine with this test. However, something changed recently and now the result object is throwing an error:
{ status: -1,
value:
