Ruby - Testing with RSpec and Minitest

require 'minitest/autorun'

class StringTest < Minitest::Test
  def test_length
    assert_equal 4, 'ruby'.length
  end
end

A1 runs, 1 failure

BRuntime error

CNo tests found

D1 runs, 0 failures

Step-by-Step Solution

Solution:

Step 1: Check the assertion logic
The string 'ruby' has length 4, so assert_equal 4, 'ruby'.length passes.
Step 2: Understand Minitest output for passing tests
One test runs and passes, so output shows 1 run, 0 failures.
Final Answer:
1 runs, 0 failures -> Option D
Quick Check:
Correct assertion = 0 failures [OK]

Quick Trick: Correct assertions mean zero failures in test output [OK]
