Technical test for Fotocasa backend developer

(For how to deliver this test, check DELIVERABLE.md)

This public service handles a list of tweets, each of 140 characters or less. The service can be described with the following user stories and acceptance criteria:

• As a User, I want to publish a Tweet.

  • A Tweet can't be empty.
  • A Tweet can't contain more than 140 characters.
  • A Tweet's Publisher name can't be empty.

• As a User, I want to view the list of published Tweets.

  • The list must be sorted by publication date in descending order.

To pass this test, we expect software that also fulfills the following list of strategic user stories

• As a User, I want to add links to the tweet text without affecting the 140 character limit.
  • A link is any set of non-whitespace consecutive characters starting with http:// or https:// and finishing with a space.
    • For example, the tweet Hey http://foogle.co is 4 characters long, instead of 20.
• As a User, I want to discard tweets.
  • Tweets shall be discarded globally, we don't need user-based discarding.
  • Discarded tweets will not be shown in the published tweet list.
• As a User, I want to view a list of discarded tweets.
  • The list must be sorted by the date it was discarded on in descending order.

Technical Requirements

• The application must fulfill all of the acceptance criteria.
• Feel free to refactor old code when adding new user stories.
• Application test coverage must not decrease.
• Do not use any framework or library not already in the codebase.
• API contracts can't be changed or modified any way.

APIs

For the two new endpoints, you must accept this API:

• As a User, I want to discard tweets:

  • POST /discarded
  • Content-Type: application/json
  • { "tweet": "%TWEET_ID%" }

• As a User, I want to view a list of discarded tweets:

  • GET /discarded
  • The response body format should be identical to the published tweets GET /tweet endpoint.
    • New fields are not allowed.

All other endpoint contracts must not be changed.
