build-test

This package is currently in BETA

Overview

This is a command line tool that performs testing and code coverage. It uses mocha to perform testing and istanbul to perform code coverage.

Guide

To start you will need to install this package for your project by executing the following command within your project from the console.

npm install --save-dev build-test

Once the package is installed you can run the tool from a terminal using the build-test command. Normally you will do this within an npm script element. Take the following excerpt from an example package.json file:

{
  "scripts": {
    "test": "build-test \"src/tests/*.spec.js\" -c \"src/**/*.js\" -c \"!src/tests/**/*.js\" ",
    "test-watch": "build-test \"src/tests/*.spec.js\" -c \"src/**/*.js\" -c \"!src/tests/**/*.js\" -w",
  }
}

In the example above the test script will run the tests found in files that end with a .spec.js extension within the src/tests/ folder. It will also provide code coverage metrics for files with an extension of .js within the src/ but not the src/tests/ folder. The test-watch script will perform testing for the same .spec.js files whenever one of them is updated or added.

Also notice that the glob patterns are surrounded by double quotes. This is necessary in order to prevent the terminal from expanding the glob patterns into actual file paths.

API

Usage:

build-test <files> [<files>] [-c <files>]  
           [-o <out directory>] [-w] [-f <format>] [-r <module>]  
           [--branches <number>] [--functions <number>] [--lines <number>] [--statements <number>]

Options:

Option	Description
<files>	A glob pattern that identifies files that contain unit tests. Multiple glob patterns can be specified.
-c	A glob pattern that identifies files to produce code coverage metrics for. Multiple glob patterns can be specified.
-f	The format for the output. Options are: console, file.
-o	The directory to send output to. This defaults to testResults/.
-r	A modue to require before any tests are run.
-w	When present the files specified in the files glob pattern(s) will be watched for changes and tested when they do change.
--branches	Global branch coverage threshold when code coverage is performed.
--functions	Global function coverage threshold when code coverage is performed.
--lines	Global line coverage threshold when code coverage is performed.
--statements	Global statement coverage threshold when code coverage is performed.
