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.

Usage

From the application folder, run

./gradlew bootRun

To get all published tweets

curl http://localhost:8080/tweet

To publish a new tweet

curl -XPOST -d '{ "publisher": "Prospect", "tweet": "Breaking the law" }' -H 'Content-Type: application/json' http://localhost:8080/tweet
