# TDD Book Store
Practice to TDD mindset
## Requirements
Think like Minimum Viable Function
### Use `success` as boolean and `reason` as string approach
- [x] 1) It should return **remaining books** if the book to borrow is existed in the store
- [x] 2) It should return the `success` as false and **original book collection** when borrow the book which isn't existed in the book store
- [x] 3) In addition to the behavior described in requirement 1, it should also return a `success` as true
- [x] 4) In addition to the behavior described in requirement 2, it should also return the `reason` as "There is no book [«book_name»] in this store"
- [x] 5) In addition to the behavior described in requirement 3, it should also return `amount` as **original amount** - 1
- [x] 6) In addition to the behavior described in requirement 2, it should also return `amount` as **original amount** and a `reason` as "The book [«book_name»] is out of stock" when that book's `amount` is `0`
### Use throwing an error and a `reason` as an **error message** approach
- [x] 1) It should return **remaining books** if the book to borrow is existed in the store
- [x] 2) It should throw an **error** when borrow the book which isn't existed in the book store
- [x] 3) In addition to the behavior described in requirement 2, it should also attach an **error message** as "There is no book [«book_name»] in this store"
- [x] 4) In addition to the behavior described in requirement 3, it should change the **error type** from a normal `Error` to be a `BookNotFoundError`
- [x] 5) In addition to the behavior described in requirement 1, it should also return an `amount` as **original amount** - 1
- [x] 6) It should throw a `BookOutOfStockError`, with the **error message** as "The book [«book_name»] is out of stock" when that book's `amount` is `0`
