RSpec失败，然后通过，然后失败

Question

Weirdly, the test suite is passing or failing intermittently. And I'm at a loss to work out why? I am changing nothing, just running the test over a over. Sometimes its green, other times its red.

Error message displayed for each error below:

Failure/Error: before { sign_in user }
     NoMethodError:
       undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_2::Nested_2::Nested_2::Nested_1:0x0000000577cb58>
