ember-try

An ember-cli addon to test against multiple bower dependencies, such as ember and ember-data.

Installation

ember install:addon ember-try

Limitations

Can only change versions for Ember 1.10+ due to template compiler changes that this addon does not attempt to handle.

Usage

This addon provides a few commands:

ember try:testall

This command will run ember test with each scenario's specified in the config and exit appropriately. Especially useful to use on CI to test against multiple ember versions.

ember try <scenario> <command (Default: test)>

This command will run any ember-cli command with the specified scenario. The command will default to ember test.

For example:

  ember try ember-1.11-with-ember-data-beta-16 test

or

  ember try ember-1.11-with-ember-data-beta-16 serve

ember try:reset

This command restores the original bower.json from bower.json.ember-try, rm -rfs bower_components and runs bower install. For use if any of the other commands fail to clean up after (they run this by default on completion).

Config

Configuration will be read from a file in your ember app in config/ember-try.js. It should look like:

module.exports = {
  scenarios: [
    {
      name: 'Ember 1.10 with ember-data',
      dependencies: {
        'ember': '1.10.0',
        'ember-data': '1.0.0-beta.15'
      }
    },
    {
      name: 'Ember 1.11.0-beta.5',
      dependencies: {
        'ember': '1.11.0-beta.5'
      }
    },
    {
      name: 'Ember canary',
      dependencies: {
        'ember': 'canary'
      }
    },
    {
      name: 'Ember beta',
      dependencies: {
        'ember': 'components/ember#beta'
      },
      resolutions: { // Resolutions are only necessary when they do not match the version specified in `dependencies`
        'ember': 'canary'
      }
    }
  ]
};

Scenarios are sets of dependencies (bower only). They can be specified exactly as in the bower.json The name can be used to try just one scenario using the ember try command.

If no config/ember-try.js file is present, the default config will be used. This is the current default config:

{
  scenarios: [
    {
      name: "ember-1.10",
      dependencies: {
        "ember": "1.10.0"
      }
    },
    {
      name: "ember-1.11.0",
      dependencies: {
        "ember": "1.11.0"
      }
    },
    {
      name: "ember-1.12.0-beta.1",
      dependencies: {
        "ember": "1.12.0-beta.1"
      }
    }
  ]
}

See an example of using ember-try for CI here, and the resulting build output.

Special Thanks

• Much credit is due to Edward Faulkner The scripts in liquid-fire that test against multiple ember versions were the inspriation for this project.

TODO

• Add tests
• Add a blueprint for the config
• Look into SilentError as seen on other ember-cli addons to see if its preferable to throw new Error for preconditions.
