var notifications = element.all(by.xpath("//div[@class='notification-content']"));
notifications.count().then(function (value) {
console.log(value);
});
console.log(value);
How to print the Value outside the promise loop which needs to compare with another variable? I need this 'value' to compare not in except statement. Please guide me.
This is a typical example of asynchronous programming in JavaScript. You can refer Protractor: what's the difference between ignoreSynchronization and async/await in Protractor this answer to understand how execution happens
Now to answer your question, you can use async/ await instead of.then and store the value.
it('should get count', async () => {
await browser.get("url of application");
let count = await element.all(by.xpath("//div[@class='notification- content']")).count();
console.log(count);
});
Hope this will solve your answer
Edit:
it("test", () => {
let count1, count2;
browser.get("url of application");
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);
});
It would be better to use async/await in this scenario. However, if you have to use the approach you posted in your snippet you would do it 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);
}
});
Try this out!
use async/await instead of promise chaining. Writing code with promise chaining is a bit complex and not gives a flexible approach to write code. https://www.protractortest.org/#/async-await
let notifications;
let value;
async GetElementCount() {
notifications = await element.all(by.xpath('//div[@class=\'notification-content\']'));
return notifications.count();
}
value = await GetElementCount();
now you can print the Value outside and compare with another variable.
