couchdb-ddoc-test

This is a simple CouchDB design doc testing tool.

Usage:

``javascript
var DDocTest = require('couchdb-ddoc-test');
var test = new DDocTest({
fixture: {a: 1},
src: 'path/to/map.js'
});
var result = test.runMap();

assert.equals(result, fixture);

CouchDB supports require() within design doc functions. It works slightly
different from require() in e.g. Node.js (in which these tests are run).
Instead of relying on CouchDB’s require() we will be using a couchapp
specific pre-processing directive. To make everything work, we have to
jump through a small hoop:

Say you want to var foo = require('foo'); within a map function. Do this:

`javascript
function(doc) {
// prepare for require
var module = module || {};

// This next line is a couchapp preprocessor line, that copy and pastes the
// contents of path/to/foo.js into this function. It should define the
// variable foo. That is how this code is run within CouchDB. !code
// path/to/foo.js

// This next line makes sure that we only run the Node.js require() when the
// !code macro is not expanded. This is why !code path/to/foo.js should
// create the foo variable. If it doesn’t exist, we run a regular Node.js
// require(). With one caveat: since map.js will be run within eval()
// in another module than your tests, we need to put the full module path into
// require(), otherwise, the foo package would have to be a dependency of
// the couchdb-ddoc-test package, which wouldn’t work out. Anyhoo!
var foo = foo || require(process.cwd() + '/different/path/to/foo'
}
