In an effort of ensuring consistent code style in test files as with
the "production" source code, we should run eslint as part of the
`$ npm test` script as well.

Most of the related fixes was done by `eslint` using the `--fix` argument.

Only special configuration tweaks for tests compared to the other
source code, is to allow functions declaration without names. The
rationale for allowing that in tests, is that the important reason we
have them in the source code (proper stacktraces) aren't as important
in test files.

Fixes this failure:

      1) Mustache CLI without partials writes rendered template into the file specified by the third argument:
         Uncaught TypeError [ERR_INVALID_CALLBACK]: Callback must be a function
          at makeCallback (fs.js:136:11)
          at Object.unlink (fs.js:943:14)
          at test/cli-test.js:86:12
          at ChildProcess.exithandler (child_process.js:285:7)
          at maybeClose (internal/child_process.js:982:16)

* prevent value from being returned by Context.prototype.lookup if lookupHit is false

* add test for renderability of Array.length via dot notation

* Remove `typeof obj === 'object'` constraint in prop lookup

Allows rendering properties of primitive types that are not objects, such as a string.

* pop lookup needs to use hasOwnProperty for non-objs

* re-add  constraint in prop lookup, but make property lookups for primitives possible through dot notation

* add test to address #589 specifically

* enhance readability of primitiveHasOwnProperty and add comments to explain why it is used in one case but not the other

parse method

Pull requests #643 and #664 together fix the issue reported in issue #617, but the change in behavior is causing semvers concerns. See issue #669. Therefore, roll back #643 and #664 and later reintroduce in next planned major release (v3.0).

Fixes #669

Resolve issue #663 and add test.

* Fixes CLI tests for windows

* Hijacked exec so we don't have to wrap each command in changeForOS, and made replacing 'cat' safer with word boundaries

* Fixing changed tests to be more consistent with the code base

It was not being asserted anywhere else, and I was suspecting that
PR #552 was changing current (and correct) behaviour.

Either vim or git was going crazy with the indentation when I tried
improving the test via changing one of the lines, so I linted it all
together.

This closes a couple of potential exploit scenarios.
Backtick (`) for older IEs and equals (=) for unquoted attributes.

Closes https://github.com/janl/mustache.js/pull/388

This fixes a small blooper introduced in a3f4339.
Error message thrown for invalid template type, should be equal on
the server and in the browser.

As we require the template to be a `string` we now throw an error when given
any other data type. This should provide the developers with a meaningful
error rather than a cryptic TypeError from the murky depths of our source code.

Fixes #464

Fixes #445

Fixes #442

Covers the project with browser tests, not only V8 via node/iojs. Tests are runned with [zuul](https://github.com/defunctzombie/zuul) which
provides simple local browser testing, aswell as cloud testing on multiple browsers with [saucelabs](http://saucelabs.com).

+ minor fix for better error message when running specific render test

Fixes #415

Fixes #431

CLI used to render a mustache template with a data view, writes the template into stdout when successfull. Otherwise meaningfull errors into stderr.

Fixes #424

Removed cache* functions altogether. mustache.parse is all that's
really needed.

Issue: If I create a Mustache lambda to return numbers and I expect 0 to be of
those numbers, I'll instead only receive an empty string for 0 because it
evaluates to falsy.

Fix: Check the result of the lambda to be undefined or null. Only then should
it return the empty string.

Fixes #258
