Description

To this evaluation i have 2 versions:

• Main branch is the more "complex" version
• MVP branch is the more simpler version of the same.

In both versions all the tests checks out. (Its all tested in travis, and code validated with Codacy)

I did some assumptions on how things should be constructed. I also avoid the use of gems. The only ones used are related with the testing framework.

TODO

• product price is required and has to be a positive value
• validate rules formating and set up default values
• when apply rule price, total price can't be lower than 0
• test cart without products shouldn't fail
• refactor rule
• refactor product
• create a rules manager
• needs a Rule#apply
• in rules should be unique products (related with rules manager)
• update readme
• should test Rules#each
• create a cart (no needed yet complexity is too low)
• extract the products and rule validation errors to its own error type
