expect.hasAssertions() triggered in different test

[a-omsk]

Hello, i found some bug while i use expect.hasAssertions || expect.assertions in async it().

My case:

https://github.com/a-omsk/x-task/blob/master/__tests__/components/Pipe.test.js

if i try to insert expect.hasAssertions() in first it() case i catch the error in next it(), but i have no any expect.hasAssertions() in second it()

 FAIL  __tests__/components/Pipe.test.js
  ● Pipe › should sequentially do the tasks passed as children

    expect.hasAssertions()

    Expected at least one assertion to be called but received none. 

My jest version: 21.0.1

Checked out your project, installed with yarn, added expect.hasAssertions() and the test passes. So cannot repro. Closing.

Actually, there's indeed a bug. .hasAssertions holds global state without resetting, so it leaks to all other test blocks.
