Search for nested Ruby object

So I have a question I want to ask my Ruby object:

Are there any failed scenarios in my testing results?

The object that I am inquiring looks like this:

=> #<Newman::Results:0x007fdcc2b48b28 @environment="dev", @build_name="customers", @build_id="119f3875-3793-4ae7-9155-78f0ce8c7047", @scenarios=[#<Newman::Scenario:0x007fdcc2b489c0 @name="POST /customers/zuora/create", @assertions=[#<Newman::Assertion:0x007fdcc2b48970 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48948 @name="GET ssoauthentication/../Authentication/token", @assertions=[#<Newman::Assertion:0x007fdcc2b488f8 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b488d0 @name="GET /users?CustomerId={customerId}", @assertions=[#<Newman::Assertion:0x007fdcc2b48880 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48858 @name="GET /locations?CustomerId={customerId}", @assertions=[#<Newman::Assertion:0x007fdcc2b48808 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b487e0 @name="PUT/users/{userId}/avatar", @assertions=[#<Newman::Assertion:0x007fdcc2b48790 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48768 @name="PUT /customers/{customerId}/logo", @assertions=[#<Newman::Assertion:0x007fdcc2b48718 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b486f0 @name="POST /customers/{customerId}/positions", @assertions=[#<Newman::Assertion:0x007fdcc2b486a0 @test="Successful POST request", @exception_message="expected 200 to be one of [ 201, 202 ]", @exception_source="AssertionError: expected 200 to be one of [ 201, 202 ]\n   at Object.eval sandbox-script.js:1:7)">]>, #<Newman::Scenario:0x007fdcc2b48678 @name="POST /users", @assertions=[#<Newman::Assertion:0x007fdcc2b48628 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48600 @name="POST /users/{userId}/invitation", @assertions=[#<Newman::Assertion:0x007fdcc2b485b0 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48588 @name="POST /registration", @assertions=[#<Newman::Assertion:0x007fdcc2b48538 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48510 @name="PUT /users/{userId}/avatar", @assertions=[#<Newman::Assertion:0x007fdcc2b484c0 @test="Status code is 200">]>, #<Newman::Scenario:0x007fdcc2b48498 @name="post to slack", @assertions=[#<Newman::Assertion:0x007fdcc2b48448 @test="Status Code is correct">]>]>

...but the gist is that there's a Results object, which has a Scenarios array filled with 1 or more Scenario objects. Each Scenario object has an Assertions array filled with 1 or more Assertion objects, and each Assertion object contains an @exception_message attribute. This @exception_message attribute will be nil unless the assertion fails, in which case it will be true.

So, going back to the question ("Are there any failed scenarios in my testing results?"): what is the best way to ask this in Ruby (not Rails)?

My best attempt, where results is my parsed results file and true or false is my desired answer:

results.scenarios.to_a.find { |scenario| scenario.assertions.to_a.find { |assertion| assertion.exception_message != nil }}

This seems to work but there must be a more efficient way.

Here's a more concise way of writing your above logic:

results.scenarios.any? do |scenario|
  scenario.assertions.any?(&:exception_message)
end

However, that's still quite a complex block of logic to put in one place. You could break this down further by doing something like:

results.scenarios.any?(&:failed?)

class Newman::Scenario
  def failed?
    assertions.any?(&:exception_message)
  end
end

Or even, to take it a step further:

results.scenario_failed?

class Newman::Results
  def scenario_failed?
    scenarios.any?(&:failed?)
  end
end

class Newman::Scenario
  def failed?
    assertions.any?(&:exception_message)
  end
end
