[Today I learned] Minitest

Minitest, a testing framework included with Ruby, is used to validate that our code behaves as expected under various conditions.
`

calculator.rb

class Calculator
def add(a, b)
a + b
end
end

tests/test_calculator.rb

require 'minitest/autorun'
require './calculator'

class TestCalculator < Minitest::Test
def test_addition
calculator = Calculator.new
assert_equal 4, calculator.add(2, 2), "Addition method failed"
end
end

Today I learned - Programming languages can be brought together

In my understanding, each project would be written using only one programming language; however, today I learned that it is possible to combine different languages in one project.
For example:
Let's say we have a script written in Ruby*:

# my_ruby_script.rb
puts "Hello from Ruby!"

We can execute this Ruby script in a Python script*:

import subprocess

# Execute the Ruby script from Python
result = subprocess.run(['ruby', 'my_ruby_script.rb'], capture_output=True, text=True)

# Print the output of the Ruby script
print(result.stdout)

Although programming languages can be used together, mixing languages can make it more difficult to read and modify code; it must be done cautiously.
