Alltheversions NPM

alltheversions

Do you just love it when dependencies make breaking changes in a patch release? Do you live for the mystery and intrigue of never quite knowing if a deploy will blow up in production? Then this is probably not the module for you!

With alltheversions, you can run your test suite against--you guessed it--all the versions of your dependencies. You simply create a versions spec file to define what modules and version ranges you want to test against, along with what task you want to run for that particular module--the default being npm test.

Usage

Basic usage is as simple as running alltheversions in the command line. However, there are some useful options, including:

-c, --config - Look for version spec file in different location
-m, --module - Only run version tests for the specified module
-v, --verbose - Include stdout of test runs in output

Versions File

A typical versions spec file looks something like this:

[
  {
    "name": "express",
    "range": "~4.0.0",
    "task": "gulp test:express"
  },
  {
    "name": "redis",
    "range": ["0.10.x","^0.12.0"],
    "task": "gulp test:redis"
  },
]

If task is omitted from a module entry, it will default to npm test, and omitting range will default it to *.
