Intern should have built-in support for snapshot testing for serializable data values. The goal would be for Intern to record values (any JSON-serializable value, like React render trees) to files and provide a way to easily update them.
The simplest API would probably be to create or use an existing chai plugin, something like chai-karma-snapshot or mocha-chai-snapshot. This would give us an API like:
Intern should have two functions accessible via the CLI: a way to update snapshots, and a way to prune them (delete any that are no longer relevant). On the config side, these could live under a snapshots property:
{
"snapshots": {
"update": true
}
}
From the command line, using the current option format in Intern master, the above config could be temporarily enabled with --snapshots-update.
