Test runner (and community) for Meteor apps. Under heavy development.

The Velocity package itself is not something that you include, rather you use Velocity-compatible framework.
To see frameworks in action, have a look at the velocity-examples repository.
Sometimes things break and its useful to get more debugging info. Most of the test frameworks support some kind of debugging environment variable flag. You can usually see a lot more details about what's happening if you run your app with this command:
$ DEBUG=1 JASMINE_DEBUG=1 VELOCITY_DEBUG=1 VELOCITY_DEBUG_MIRROR=1 meteor
Please report bugs directly on the issues of the framework(s) you are using. Framework authors will then post issues to the core if they are core issues.
##Velocity Compatible Packages
Below is a list of the currently available frameworks.
####Fully Integrated
These frameworks have an example in the velocity-examples repository. They also include a set of sample tests that the framework can add directly to the reporter when you first install the framework.
- sanjo:jasmine - Write client and server unit and integration tests with Jasmine.
- mike:mocha - A Velocity version of mocha-web. Runs mocha tests in the Meteor context which is great for integration testing.
- xolvio:cucumber - Use Gherkin-syntax cucumber to test your app. Integrated nicely with meteor-webdriver
####Partially Integrated
These frameworks are very usable, and they are placed under this section as they currently don't have an example app and do not offer a sample-test button in the reporter.
- clinical:nightwatch - run acceptance tests with automated browsers using the Nightwatch bridge to Selenium
- nblazer:casperjs - CasperJS end to end test integration
Reporters display test results.
- velocity:html-reporter - Adds an overlay to your app indicating test success/failure (green/red dot in top right). Click dot for test details.
meteor add velocity:html-reporter
Mirrors are used by test frameworks to run tests within. Tests are typically destructive and as such require a different database. Mirrors run a parallel version of your app with a different database as not to intrude on the main development workflow.
- node-soft-mirror - This mirror offers an extremely fast startup time. It creates a mirror using a node form from within the running meteor process.
- xolvio:webdriver - Adds webdriver.io to any test framework for UI testing. Uses PhantomJS in GhostDriver mode for ultra-fast UI testing
We would love to add your framework to the list! Take a look at how some of these interface with velocity and let us know about your framework on the velocity-core google group.
Please see the velocity-wiki for basic instructions on making your test framework work with Velocity.
Also, be sure to check out the documentation for the public API. You can view them in the browser by cloning this repo and then running: open docs/classes/Velocity.html
A few notes on being velocity-compatible:
Use Velocity.registerTestingFramework(frameworkName, options)
to register your package as testing framework. You can find a description of the expected arguments in the docs.
Please put some sample tests in a directory named sample-tests
at the root of your package.
These will be used by the velocity-quick-start package and also allows users to click a button
in the html-reporter to have them added to their apps.
Please include a way to get more detailed info about your frameworks' test runs.
One way that we've done it is by having an environment flag that the user can set. Feel free to use VELOCITY_DEBUG
if you'd like.
For example, you could write your logging like this:
var DEBUG = process.env.VELOCITY_DEBUG;
DEBUG && console.log('[my-framework] helpful debugging info', someVar)
- Clone https://github.com/meteor-velocity/velocity-examples.git
- Create a symlink to your local velocity:core package:
cd velocity-examples/leaderboard-jasmine
mkdir packages
cd packages
# Replace ~/velocity with your path
ln -s ~/velocity velocity:core
- Start the velocity example app. It will use your local velocity:core version.
cd ..
meteor
- Make code changes
- Commit changes
- Update History.md with summary of changes
- Bump version numbers in package.js, History.md and yuidoc.json
- Execute
yuidoc
command from velocity root path - Commit changes
meteor publish
- Tag last commit with the new version
X.X.X
- Push to github. Also push the new tag! (
git push --tags
)
We have to publish velocity:core for the different architectures (Mac OS, 64-bit Linux and 32-bit Linux).
First publish velocity:core on your development machine with meteor publish
. Then you will need machines with the other two architectures. Use meteor publish-for-arch velocity:core@VERSION --release 0.9.4
on a computer with the right architecture. Also see Meteor docs.
We have two naming schemas:
- When the method does something with a resource type:
velocity/<RESOURCE_NAME>/<ACTION>
- When the method isn't specific to a resource type:
velocity/<ACTION>
All parts are camelCase and start with a lowercase letter.
