What is the best way to get the count of elements on a page? Here is my code snippet:
public countElements(){
element.all(by.repeater('app in userApps')).count().then(function(count) {
console.log(count);
});
return count; // unable to retrieve element count
}
I understand that the count is invisible outside the function, but how can I make it visible? How can I properly return the count variable in the method countElements() ?
function getTotalElements(){
return elements.all(by.repeater('item in items')).count();
}
Next, in the testing phase:
page.getTotalElements().then(total => {
console.log(total);
expect(total).toBe(expectedTotal);
});
If you want to use the total count in other functions, consider using async/await.
let total = await page.getTotalElements();
anotherFunction(total);
Alternatively, you can create your custom promise and resolve it. You can achieve this by implementing something similar to the following code.
function getTotalElements(){
return new Promise((resolve, reject) => {
elements.all(by.repeater('item in items'))
.count()
.then(total => {
if(total > 0) {
resolve(total);
} else {
reject('An error occurred...');
}
});
}
}
