📦 boxtape

This is just regular tape, but with some quality of life improvements for the ESM era.

Usage

See tape.

npm install boxtape

# If you use typescript:
npm install @types/tape
boxtape tests/**/*.js
import test from 'boxtape'

Additions

beforeEach

import test from 'boxtape'

test.beforeEach(async (t) => {
  // Do something before each test.
})

afterEach

import test from 'boxtape'

test.afterEach(async (t) => {
  // Do something after each test.
})

Default TAP Output Formatter

This uses a fork of tap-pretty to provide a nice output by default. The fork has added error stack trace so that you can navigate to where the error occurred.

error example

Since boxtape automatically pipes tape output into tap-pretty, you cannot pipe into your own tap formatter.

Examples

Frontend Testing

Here is a simple example to get you started for frontend testing.

// In this example, we are doing some frontend testing.
import test from 'boxtape'
import sinon from 'sinon'
import {JSDOM} from 'jsdom'

// Load DOM functions:
const dom = new JSDOM()
global.document = dom.window.document
global.window = dom.window

sinon.spy(document)

test.beforeEach(() => {
  // Maybe you want to reset your spy counts:
  for (const method in document) {
    if (typeof document[method] === 'function') {
      if (document[method].callCount !== undefined) {
        document[method].callCount = 0
      }
    }
  }
})
