var alerts = element.all(by.xpath("//div[@class='notification-content']"));
alerts.count().then(function (val) {
console.log(val);
});
let compareValue = val;
Is there a way to access the 'value' outside of the promise loop for comparison with another variable? I want to compare this 'value' without using an exception statement. Any guidance would be appreciated.
Here's a great example showcasing asynchronous programming in JavaScript. To delve deeper into this topic, check out Protractor: Exploring the variance between ignoreSynchronization and async/await in Protractor. This will provide clarity on how the execution process unfolds.
To address your query, consider implementing async/await instead of .then to capture and save the value.
it('should retrieve count', async () => {
await browser.get("application URL");
let count = await element.all(by.xpath("//div[@class='notification-content']")).count();
console.log(count);
});
Hoping this resolves your question.
Edit:
it("test", () => {
let count1, count2;
browser.get("application URL");
var notifications = element.all(by.xpath("//div[@class='notification-content']"));
count1 = notifications.count();
var notifications = element.all(by.xpath("//div[@class='notification-content']"));
count2 = notifications.count();
expect(count1).toBe(count2);
});
In this situation, it is recommended to utilize async/await for better performance. However, if you must proceed with the method provided in your snippet, the implementation would look like this:
var notifications1 = element.all(by.xpath("//div[@class='notification-content1']"));
var notifications2 = element.all(by.xpath("//div[@class='notification-content2']"));
notifications1.count().then(function (count1) {
notifications2.count().then(function (count2) {
expect(count1).toEqual(count2);
}
});
Give it a try!
Instead of using promise chaining, consider implementing async/await. Promise chaining can be complex and may not offer the same flexibility when writing code. Check out this link for more information on async/await.
let notifications;
let value;
async function GetElementCount() {
notifications = await element.all(by.xpath('//div[@class=\'notification-content\']'));
return notifications.count();
}
value = await GetElementCount();
You can now print the 'value' variable outside and compare it with another variable.
