$ cnpm install harness
harness-js
Yet another test organizers except that is work in NodeJS, Mongo's shell. Being able to run across these three environments with depending on things like RequireJS was a major reason to write this module. Hopefully it is helpful to others.
Overview
Harness provides a simple way of organizing assertive tests in Mongo's shell (using mongo-modules), NodeJS and in many web browsers.
NodeJS example
var path = require("path"),
assert = require("assert"),
harness = require("harness");
// Setup a test by assigning a function to callback and
// a label to the test group.
harness.push({callback: function () {
assert.strictEqual(harness.counts("running"), 1, "Should have on test running for 'Testing push()'");
// Now that you've completed this test
// group tell harness that this label
// is now complete.
harness.completed("Test group 1");
}, label: "Test group 1"});
// This is a second test group just to show you can do
// more than one group of tests.
// Setup a test by assigning a function to callback and
// a label to the test group.
harness.push({callback: function () {
assert.strictEqual(harness.counts("running"), 2, "Should have on test running for 'Testing push()'");
// Now that you've completed this test
// group tell harness that this label
// is now complete.
harness.completed("Test group 2");
}, label: "Test group 2"});
harness.RunIt(path.basename(module.filename), 10);
The command to run example/node-example.js looks like-
node example/node-example.js
The output would look something like-
Starting [node-example.js] ...
Starting Test group 1 ...
Test group 1 called
Test group 1 OK
Starting Test group 2 ...
Test group 2 called
Test group 2 OK
node-example.js Success!
Mongo example
Harness support comes with mongo-modules and mongo-modules will need to be installed for it to work. Other than that it looks much like the NodeJS version above. The difference is that the module.filename object isn't defined by mongo-modules so we must define that ourselves.
var path = require("path"),
assert = require("assert"),
harness = require("harness"),
// mongo-modules does not define the module object's
// filename.
module = {
filename: "mongo-example.js"
};
// Setup a test by assigning a function to callback and
// a label to the test group.
harness.push({callback: function () {
assert.strictEqual(harness.counts("running"), 1,
"Should have on test running for 'Testing push()'");
// Now that you've completed this test
// group tell harness that this label
// is now complete.
harness.completed("Test group 1");
}, label: "Test group 1"});
// This is a second test group just to show you can do
// more than one group of tests.
// Setup a test by assigning a function to callback and
// a label to the test group.
harness.push({callback: function () {
assert.strictEqual(harness.counts("running"), 2, "Should have on test running for 'Testing push()'");
// Now that you've completed this test
// group tell harness that this label
// is now complete.
harness.completed("Test group 2");
}, label: "Test group 2"});
harness.RunIt(path.basename(module.filename), 10);
Running the example/mongo-example.js with mongo-modules available is done like-
mongo ~/.mongojs.rc example/mongo-example.js
The output should look something like-
MongoDB shell version: 2.2.0
connecting to: test
loading file: /Users/johndoe/.mongorc.js
loading file: example/mongo-example.js
Starting [mongo-example.js] ...
Starting Test group 1 ...
Test group 1 called
Test group 1 OK
Starting Test group 2 ...
Test group 2 called
Test group 2 OK
mongo-example.js Success!
