We are going to be working with a collection of objects. We've been provided two classes and tests that describe the behaviors of the classes. Take a look at the provided code.

The Soda class have been created for us. Furthermore, tests have been provided that describe the behaviors of this class. Read the code for these classes and the test code because we'll be working with these objects later.

The SodaMachine class is somewhat complete. We can initialize an instance of SodaMachine with a collection of sodas. The challenge is to write methods that provide a SodaMachine instance with ways of interacting with its sodas. The desired behaviors have been described in tests, but are summarized here, in English:

• A soda machine will be able to return the number of sodas it contains. This method should be called SodaMachine#current_inventory_count.
• A soda machine will be able to find a single soda with a given brand. This method will be called SodaMachine#find_soda.
• A soda machine will be able to sell a soda with a given brand. When a soda is sold, it should be removed from the soda machine and the price of the soda should be added to the soda machine's cash This method will be called SodaMachine#sell.

Use RSpec to help validate that your implementation meets these provided expectations.

To run all the tests, you can use:

rspec spec

or simply:

rspec

To run the tests for a specific file, you can use:

rspec spec spec/<file_name_goes_here>

If you would like RSpec to stop running the tests as soon as it executes a failing test, you can use the --fail-fast option with any of the above commands. This will cut down on the output and may make it easier to read.

Update the SodaMachine class in soda_machine.rb to make the tests pass.

Do not modify the tests and do not modify the Soda class.
