Yasnippets for the Buster test framework.

branch: master
README.md

buster-snippets.el

Yasnippets for the Buster javascript testing framework.

Common snippets

tc => new testCase (one for node, browser and node+browser)
tt => additional test
cx => nested context
su => setup method
td => teardown method

Assert and refute snippets follow a common pattern. They start with as or re followed by a mnemonic shortcut. Most are simply the 'initials' of the method name, but the best shortcuts are saved for the most common assertions.

ase - assert.equals
asm - assert.match
ass - assert.same
asx - assert.exception
asd - assert.defined
ast - assert.threw
asat - assert.alwaysThrew
asin - assert.isNull
asio - assert.isObject
asto - assert.typeOf
ascn - assert.className
astn - assert.tagName

Buster also includes Sinon and its assertions:

asc - assert.called
asc1 - assert.calledOnce
asc2 - assert.calledTwice
asc3 - assert.calledThrice
ascw - assert.calledWith
ascc - assert.callCount
asco - assert.callOrder
asco - assert.calledOn
asaco - assert.alwaysCalledOn
asacw - assert.alwaysCalledWith
asacwe - assert.alwaysCalledWithExactly
ascwe - assert.calledWithExactly

Refutations mirrors assertions exactly, except that they start with re instead of as. It is the beautiful symmetry of the buster assertions package.

Installation

If you haven't, install yasnippet then install buster-snippets like so:

git submodule add https://github.com/magnars/buster-snippets.el.git site-lisp/buster-snippets

Then require buster-snippets at some point after yasnippet.

(require 'buster-snippets)

Customization

Add "use strict"-declarations to the test cases:

(setq buster-use-strict t)

Declare assert and refute if you've disabled additional globals:

(setq buster-exposed-asserts nil)

Set the default global namespace-object on a per-project basis:

(add-hook 'js2-mode-hook
      (lambda ()
        (when (string-match-p "projects/zombietdd" (buffer-file-name))
          (setq js2-additional-externs '("ZOMBIE"))
          (setq buster-default-global "ZOMBIE"))))

;; example from one of my projects

Add the default global to the IIFE (immediately invoked function expression)

(setq buster-add-default-global-to-iife t)

The global will by default be shortened to a one-letter var, like this:

(function (Z) {

   // use Z instead of ZOMBIE inside the namespace

}(ZOMBIE));
