Luminus 를 이용한 Clojure 방명록 만들기 (5) - 테스트 및 패키지화

Luminus 를 이용한 Clojure 방명록 만들기 (5)

Adding some tests

이제 어플리케이션이 작동할 준비를 마쳤다. 몇 가지 테스트를 하기 위해 test/clj/guestbook/test/db/core.clj 파일을 열어 다음과 같이 업데이트해보자. 

/home/fukaerii/guestbook/test/clj/guestbook/test/db/core.clj

(ns guestbook.test.db.core
  (:require [guestbook.db.core :refer [*db*] :as db]
            [luminus-migrations.core :as migrations]
            [clojure.test :refer :all]
            [clojure.java.jdbc :as jdbc]
            [guestbook.config :refer [env]]
            [mount.core :as mount]))
 
(use-fixtures
  :once
  (fn [f]
    (mount/start
      #'guestbook.config/env
      #'guestbook.db.core/*db*)
    (migrations/migrate ["migrate"] (select-keys env [:database-url]))
    (f)))
 
(deftest test-message
  (jdbc/with-db-transaction [t-conn *db*]
    (jdbc/db-set-rollback-only! t-conn)
    (let [message {:name "test"
                   :message "test"
                   :timestamp (java.util.Date.)}]
      (is (= 1 (db/save-message! t-conn message)))
      (let [result (db/get-messages t-conn {})]
        (is (= 1 (count result)))
        (is (= message (dissoc (first result) :id))))))
  (is (empty? (db/get-messages))))

이제 작동시켜보자.

터미널 상에서 lein test 명령을 실행시켜 데이터베이스와의 연동작업이 제대로 이루어지고 있는지 확인할 수 있다.

이 과정에서 에러가 발생하는 경우 다음 링크를 참조한다.

Luminus 는 기본적으로 lein-test-refresh 명령을 사용할 수 있게 되어있다. 이 플러그인은 네임스페이스상의 변화를 자동으로 감지하여 지속적으로 테스트를 진행한다.

Packaging the application

어플리케이션은 개별배포를 위해 다음의 명령을 통해 패키징이 가능하다. 

lein uberjar

이를 통해 다음과 같이 실행할 수 있는 jar 를 만들 수 있다.

export DATABASE_URL="jdbc:h2:./guestbook_dev.db"
 
java -jar target/uberjar/guestbook.jar
 
 

다만 jar 로 실행할 때는 DATABASE_URL 환경변수를 제공해야한다는 점을 기억해야 한다. 

최종완성본을 구동해보자.
