Test inbox pagination after loading all messages

[sosnovsky]

Steps:

1. Login to e2e account
2. Observe Inbox screen - 36 emails are displayed
3. Pull down for refresh
4. Observe Inbox screen - it should load all 36 emails

Previously there was an issue when after loading all 36 emails and performing pull-to-refresh only 20 emails were loaded (#1284)

But emails count probably will change in the future, so test shouldn't depend on it - it'll be better to compare title of the last message on first load with last email title on the second load (after pull-to-refresh).

@sosnovsky I get email count from inbox before scroll and after, and check that counts after scroll should be great than before

[sosnovsky]

Ah, great, then we should check if total email count after pull-to-refresh is the same as on the first load (currently it's 36 emails)

@sosnovsky sure, how many email should be in Inbox screen for check pagination?
I tried to check it in e2e account but 36 email in not enough

[sosnovsky]

Initial issue happened only after user have loaded all messages in Inbox. Is it possible to check when all emails have loaded?
Like this:

1. scroll down
2. check if number of emails changed
3. if changed - scroll down one more time to load next page of emails
4. if emails count didn't change - all messages are loaded, can do pull-to-refresh now

For this case we have this ticket, #1156

but I dont know how many emails should be in inbox for pagination, with 36 emails pagination is not working, i think we need more emails

[fcvakintos]

I found 1 page contains 40 emails

[sosnovsky]

I think currently we have 20 emails per page

[fcvakintos]

@sosnovsky hmmm. strange
I have 40 emails in page
but after open some email/ click back to inbox screen-> the emails count = 20

On 00:10 of your video you can see how page #2 of email is added on the bottom, as next page is automatically loaded when you scroll to the bottom of the list. So each page contains 20 emails which are automatically loaded on scroll.

But I just noticed another bug - emails shouldn't disappear when you go back from email detail screen. And also there is something wrong with sorting, as email with Jan 10 date is below emails from November. I'll create separate issue for these issues
