Pry doesn't work when launched from method invoked by RSpec test - ruby

Question

I'm trying to use Pry with RSpec.
Goal is to be able to drop binding in method and debug it.
Here is what I have.
lib/play.rb
class Play
def self.hello
print 'Hello world!'
require 'pry'; binding.pry
end
end
spec/play_spec.rb
require_relative '../lib/play'
describe Play do
it 'Play#hello should print message' do
expect {Play.hello}.to output('Hello world!').to_stdout
#require 'pry'; binding.pry
end
end
If I uncomment binding in spec file and run
rspec
I'm getting into Pry which behaves as expected

If I comment out binding.pry in spec fill, put it in method which is tested and invoke "rspec" again. I'm getting into completely messed Pry.

Anyone faced such issue?

Answer 1

As the answer by OP indicates, the problem involves console output suppression, which can inadvertently break Pry.
If you check your spec/spec_helper.rb file, there is likely some code inside the RSpec configuration block that is referring to $stderr and/or $stdout. Removing those lines of code should fix the problem.
For other examples of how this output might be getting suppressed, see the answers to this question: Suppress console output during RSpec tests

Answer 2

Issue resolved by removing stdout capturing from test. Thanks everyone.
