Instructions to start the server

• Clone Git repository at https://github.com/muratdozen/BE_music_MURAT_DERYA_OZEN/
• On the terminal, change directory (cd) to nodejs directory.
• Issue the command npm install. This will install required dependencies including the ones listed in package.json.
• Issue the command node app.js
• The server shall start and you shall see an output similar to the following:

Last login: Thu Mar 20 04:23:37 on ttys001
murat:BE_music_MURAT_DERYA_OZEN murat$ pwd
/Users/murat/Documents/code/git/BE_music_MURAT_DERYA_OZEN
murat:BE_music_MURAT_DERYA_OZEN murat$ cd nodejs
murat:nodejs murat$ node app.js
Loading musics json file from '/Users/murat/Documents/code/git/BE_music_MURAT_DERYA_OZEN/nodejs/public/json/musics.json'
Express server listening on port 3000

Instructions to test

• After the server has started, cd to nodejs directory.
• Issue the command mocha "test/acceptance/test.user-acceptance.js" | grep "Recommendations result" -A 9
• This command (1) tells mocha to execute the acceptance test and (2) from output produced by mocha, grep the line containing Recommendations result and 9 other lines after it.
• The output should be similar to the following:

murat:nodejs murat$ mocha "test/acceptance/test.user-acceptance.js" | grep "Recommendations result" -A 9
Recommendations result for userId 'a':
{
  "list": [
    "m7",
    "m4",
    "m8",
    "m9",
    "m10"
  ]
}

If mocha is not listed under your PATH variable, providing the path for the executable should work out fine: ./node_modules/.bin/mocha "test/acceptance/test.user-acceptance.js" | grep "Recommendations result" -A 9

The acceptance test located at test/acceptance/test.user-acceptance.js loads and parses follows.json and listen.json files, feeds in these input to POST /follow and POST /listen endpoints and finally issues a GET /recommendations request for user a and outputs the results.

The json input files are located under test/acceptance/input.
