                        Don't know how to get step code to run
I've posted this question twice to the cucumber slack and no response, so asking here now. I was under the impression from the docs that I could use cucumber core to execute and report on tests.
I am trying to use cucumber core to make a test runner that can be executed from ruby code. I'm wanting to use my runner to run tests (with step code) concurrently while being able to fully control behavior and reporting.
My apologies if this is obvious but it appears to me now that the cucumber core api itself does not execute step code and I would like to know (or pointed to some examples/docs of) how to use cucumber core to accomplish the above.
I have made a runner referencing the docs here
My tests have some set to fail expect(1).to eql(2) but when running with my test runner they all are marked as passed and it seems the step code is not run at all.
Here is the output from running my tests
Para cukes are running ✓ Tests will finish ✓ Para runner one is running--PASSED Para cukes are running ✓ Tests will finish ✓ Para runner two is running--PASSED Para cukes are running ✓ Tests will fail ✓ Para runner three is running--PASSED Para cukes are running ✓ Tests will fail ✓ Para runner four is running--PASSED
The steps "Tests will fail" should fail and not be marked as pass (they fail when running with the CLI)
Here is my runner code
class CoreRunner
  include Cucumber::Core
end
# Custom runner class using cucumber API
class ParaRunner
  def run
    scenario = 'features/test/para_runner/para_test_2.feature'
    file_body = File.read(scenario)
    feature = Cucumber::Core::Gherkin::Document.new(scenario, file_body)
    CoreRunner.new.execute([feature], [ActivateSteps.new]) do |events|
      events.on(:test_step_finished) do |event|
        test_step = event.test_step
        result = event.result
        puts "#{test_step.text} #{result}"
      end
      events.on(:test_case_finished) do |event|
        puts "#{event.test_case.name}--#{event.result.to_message.status}"
      end
    end
  end
end
# Activator
class ActivateSteps < Cucumber::Core::Filter.new
  def test_case(test_case)
    test_steps = test_case.test_steps.map do |step|
      activate(step)
    end
    test_case.with_steps(test_steps).describe_to(receiver)
  end
  def activate(step)
    step.with_action {}
  end
end
Thanks for all your help!
Are you able to get up something runnable ideally in the form of a branch against this repo or a fork that shows the failing test? I'll be able to look at it better that way as I don't have huge amounts of free time now
It looks like your step code "might" be the issue here. But I can't say for certainty as I've not used this area of the codebase much
Hello @luke-hill and thanks for the suggestion. Sorry for the delayed response, I was on vacation then got sick :(
I have recreated the code I have in my project in a fork of cucumber core here https://github.com/calderete/cucumber-ruby-core
I added a test that can be run with rspec spec/custom_runner_spec.rb because of the nature of the behavior though I cannot get it to fail.
Here is the step code
When('Some cukes are running') do
  $stdout.puts('This step is running')
end
Then('This test will fail') do
  $stdout.puts('This step should fail')
  expect(2).to eql(3)
end
The console does output the scenarios so it seemed to find the scenarios but appears disconnected from the step code in my implementation.
The log outs are not printing and the test gets marked as passed. Because of this I'm not able to make failing test, but it demonstrates that the step code is not being run.
If you could see what I'm doing wrong here I would much appreciate it!
Thanks for all you do!!
