proposal: basic skeleton test files

[jokeyrhyme]

Proposal is to detect ava, mocha, jest, jasmine, tape, and other popular test frameworks. If none of these exist, then install a preferred test framework and copy in basic skeleton files so the developer can get started more quickly.

ava

• each test file executes in its own process (easy environment isolation)

• test files are auto-transpiled with babel and power assertions

• tests execute concurrently (non-deterministic sequence) by default

• provides runner and assertions in 1 devDependencies entry

• mocks and coverage via 2 extra devDependencies

• provides assertion for auto-snapshot testing

• npm install pulls down babel and half the NPM eco-system

• runner does not execute in the browser (but tests could hit browser automation APIs)

• runner provides grouping and before/after each/all functionality

jest

• each test file executes in its own process (easy environment isolation)

• supported by Facebook

• provides runner, assertions, mocks, and coverage all in 1 devDependencies entry

• provides assertion for auto-snapshot testing

• assertions smell like BDD (but at least they are isDoneCorrectly(), not is.done.correctly)

• runner does not execute in the browser (but tests could hit browser automation APIs)

• runner provides grouping and before/after each/all functionality

mocha

• provides runner in 1 devDependencies

• assertions, mocks, and coverage via 3 extra devDependencies

• runner executes in both Node.js and the browser

• runner provides grouping and before/after each/all functionality

tape

• provides runner and assertions in 1 devDependencies

• mocks and coverage via 3 extra devDependencies

• runner executes in both Node.js and the browser
