Deprecate Support for ember-cli-qunit and ember-cli-mocha When Generating Test Blueprints

Summary

This RFC proposes to deprecate support for ember-cli-qunit and ember-cli-mocha when generating test blueprints.

Motivation

Both ember-cli-qunit and ember-cli-mocha were deprecated a long time ago in favor of ember-qunit and ember-mocha respectively.

Deprecating (and later on, removing) support for both addons would greatly reduce the amount of test blueprints we have in ember-source and ember-data.

Transition Path

The test-framework-detector.js files in ember-source and in ember-data will be updated to display a deprecation message whenever ember-cli-qunit or ember-cli-mocha is detected when generating test blueprints:

Support for `ember-cli-qunit` when generating test blueprints has been deprecated.
Please migrate to using `ember-qunit` instead.

Deprecation details:

Key	Value
for	'ember-source'
id	'ember-source.ember-cli-qunit-test-blueprints'
since	{ available: '4.X.X', enabled: '4.X.X' }
until	'5.0.0'

NOTE: ember-cli-qunit and ember-source in the deprecation message and details above should be replaced with ember-cli-mocha and ember-data appropriately.
