# 7. Prefer running QUnit tests in node.js

|
Accepted
|
||
|
|
|
||
|
|
## Context
|
||
|
|
|
||
|
|
QUnit tests were set up to run on a browser or phantom.js on top of a running
|
||
|
|
mediawiki server.
|
||
|
|
|
||
|
|
We want to:
|
||
|
|
* Speed up the test running in a development cycle
|
||
|
|
* Full page reload every time you change tests or source takes too long
|
||
|
|
* Leverage common.js in our tests to load our sources and other test helpers
|
||
|
|
like stubs
|
||
|
|
* Remove global variables
|
||
|
|
|
||
|
|
## Decision
|
||
|
|
|
||
|
|
QUnit tests will be migrated from `tests/qunit/ext.popups/` to
|
||
|
|
`tests/node-qunit/` and will be run by the script `npm run test:node` in a node
|
||
|
|
environment with access to QUnit, a fake jsdom, and jQuery. Powered by the node
|
||
|
|
package `mw-node-qunit`.
|
||
|
|
|
||
|
|
Node tests will be run in CI too in the npm job that runs `npm test`.
|
||
|
|
|
||
|
|
It is preferred to use the node-qunit test environment, as it is fast,
|
||
|
|
leverages common.js modules, and isolated.
|
||
|
|
|
||
|
|
When impossible because of extreme coupling with mediawiki.js, put the
|
||
|
|
**integration** tests in `tests/qunit/`.
|
||
|
|
|
||
|
|
## Consequences
|
||
|
|
|
||
|
|
* README has instructions on how to run different types of tests
|
||
|
|
* Node based QUnit tests...
|
||
|
|
* can be run independently of mediawiki
|
||
|
|
* are isolated and need to stub global variables used in sources
|
||
|
|
* are run in node.js 6+ which runs in CI on wikimedia infrastructure
|
||
|
|
* which means they leverage that platforms advantages (loading files with
|
||
|
|
common.js, using es6, using the node stdlib if necessary)
|
||
|
|
* Most tests are migrated to `tests/node-qunit` and only the ones that strictly
|
||
|
|
need it remain in `tests/qunit` (`processLinks.test.js` for example, see
|
||
|
|
comment in file)
