3.5 Testing with lab and code

Testing with lab and code

Make sure lab and code are installed.
Install Instructions

Make directory and files:
./test/index.js
./test/version.js.

Configure package.json and Makefile for testing

step1: Configure package.json to allow npm to execute needed test commands.
npm run syntax allows you to run custom commands with npm.
This package.json illustrates npm run syntax

 "scripts": {
    "start": "node start.js",
    "test": "lab",
    "test-coverage": "lab -t 100",
    "test-coverage-html": "lab -r html -o test/coverage.html"
  },

The above part of the package.json file allows you to run commands like:
npm run test // This executes: lab -t 100.
npm run test-coverage // executes:lab -t 100

step2: Use Makefile to simplify the commands you run.
Important: put ".PHONY: all test clean" in your make file to ensure the
command "make test" does not conflict with the ./test directory.
See Sample Makefile

Build tests for corresponding files in /lib.

Make sure you get 100% coverage.
Important: Use your Makefile commands as short cuts to execute your tests.
For example:
make test (should run your tests)
make cov (should run your coverage tests)
See Sample Makefile
