assert-snapshot
Snapshot UI testing for tape tests. Inspired by Jest snapshot testing, but implemented as a module instead of a custom runtime.
Usage
var snap = var tape = var html = { return html` Hello planet `}
Outputs
TAP version 13# my cool componentok 1 snapshot found for "my cool component"ok 2 <section>ok 3 ·· Hello planetok 4 </section> 1..4# tests 4# pass 4 # ok
Updating snapshots
By default no snapshot is saved. Set the UPDATE_SNAPSHOT=true
env variable to
update the snapshot and save it to snapshot.json
. Each snapshot is saved
using the name of the test as the key, so make sure test names are unique.
$ UPDATE_SNAPSHOT=true node example.js
API
snapshot(assert, html, [cache])
Assert a string of HTML using a custom assert function. Takes an optional cache object that contains the expected values. Use this if snapshot tests become I/O bound.
