After upgrading rails from 4.2 to 5.2 my test gets stuck on a request while it is working in development server I'm getting following failure on running test suit.

in my spec the line sign_in current_user takes too much time actually it redirects to a page and do not get response even long time while it is working on development environment.
what can be the reason if you need anything else please comment.
I've just arrived here myself after upgrading from 4.2 to 5.1 and now 5.2, and I'm seeing the same thing in my testing, when I have frozen a test in mid-request with binding.pry, I get the message Requests did not finish in 60 seconds. What a great story, skip to the end for tl;dr (I may have figured it out.)
Now I have upgraded all of the gems, incrementally so I can preserve the capacity to bisect and observe the source of interesting changes like this one. I only noticed this new 60 second timeout after changing over from chromedriver-helper which reported it had been deprecated to the new webdrivers gem that's taking over, but that seems to be not related as I searched webdrivers for any timeout or 60 second value, and only found references to an unrelated Pull Request #60 (fixes Issue #59).
I checked my gem source directory for this message, Requests did not finish in 60 seconds, and found it was not in fact an older version of Capybara, but that it has been raised from versions dating back to at least 3.9.0, and in the most current version 3.24.0 in lib/capybara/server.rb.
The object used there is a Timer which you can find an interface to it here, in the helper:
This particular message is raised out of the method wait_for_pending_requests which passes a hard 60 into the :expire_in named parameter, then after sends any errors that were encountered in the server thread. This means the time is not configurable, probably 60 seconds is a reasonable length of time to wait for a web request in progress to complete, although it's a bit inconvenient for my test.
That method is only called in one place, reset!, which you can find defined here in capybara/session.rb: https://github.com/teamcapybara/capybara/blob/320ee96bb8f63ac9055f7522961a1e1cf8078a8a/lib/capybara/session.rb#L126
The reset! method is an interesting one that comes with some documentation about how it's used. @server&.wait_for_pending_requests looks like it might call wait_for_pending_requests if it has an active server thread in a request, and then raise_server_error! which similarly acts only if @server&.error is truthy.
Now we find that reset! comes with two aliases, this message reset! is received whenever Capybara calls cleanup! or reset_session!. At this point we can probably understand what happened, but it's still a little bit mysterious when I've been using chromedriver-helper and selenium testing for several years, but never recall seeing this 60 second timeout before. I'm hesitant to point the finger at webdriver, but I don't have any other answers for why this timeout is new. I haven't done really anything that could account for it but upgrade to this gem, and any other gems, plus clearing out deprecation warnings.
It seems possible that in Rails 5.1+, capybara calls reset! a lot more, maybe more than in between test examples. Especially when you read that documentation of the method and think about what Single-Page focus there has been now, and consider all of the things that reset! documentation tells you it doesn't reset, clear browser cache/HTML 5 local storage/IndexedDB/Web SQL database/etc — or maybe I'm imagining it, and this isn't new. But I'm imagining there are a lot of ways that it can call reset! and not land in this timeout code, that are likely to be driver-dependent.
Did you change to webdrivers gem by any chance when you did your Rails upgrade?
Edit: I reverted to chromedriver-helper just to be sure, and that wasn't it. What's actually happening is my test is failing in one thread, but the server has left a binding.pry session open. Capybara has moved onto the next test, and thus to get a fresh session it has called reset!, but 60 seconds later I am still in my pry session, and the server is still not ready to serve a root request. I have a feeling that the threading behavior of capybara has changed, in my memory a pry session opened during a server request would block the test from failing until it had returned. But that's apparently not what's happening anymore.
How did you arrive here? I have no idea unfortunately, but this is a fair description of what's happening when that message is received.
