Ruby - Testing with RSpec and Minitest

What will be the result when running this RSpec test?

describe 'Array' do
  it 'checks size' do
    expect([1, 2, 3].size).to eq(4)
  end
end

AThe test will pass successfully

BThe test will fail because the expected size is incorrect

CThe test will raise a syntax error

DThe test will be skipped

Step-by-Step Solution

Solution:

Step 1: Analyze the test code
The array has 3 elements, but the expectation is 4.
Step 2: Understand RSpec behavior
RSpec will run the test and fail because the expectation does not match the actual value.
Final Answer:
The test will fail because the expected size is incorrect -> Option B
Quick Check:
Expectation mismatch causes test failure [OK]

Quick Trick: Mismatch between actual and expected causes failure [OK]
