About this piece

Test Runner

Test list that runs top to bottom, each spinner resolving into a green check or a red cross while the summary counts passes and failures and a thin bar tracks progress.

Usage

The import and the props worth knowing about, in one place.

import { Code15 } from "@/components/beste/piece/code15";

<Code15
  filename="checkout.test.ts"
  tests={[
    {
      "name": "renders cart summary",
      "duration": 18
    },
    {
      "name": "applies coupon code",
      "duration": 42
    },
    {
      "name": "rejects expired coupon",
      "duration": 31
    },
    {
      "name": "calculates shipping",
      "duration": 124,
      "fails": true
    },
    {
      "name": "charges saved card",
      "duration": 87
    }
