## What it is
tape is a minimalist TAP-producing test harness for Node.js and browsers. It lets you write tests as simple function calls with assertions and outputs standard TAP results.

## Use cases
- run unit tests in node
- produce TAP output for test runners
- write tests without a heavy framework
- run tests in the browser
- assert values in javascript tests

## When to choose
- you want a tiny, dependency-light test harness
- you need TAP-compatible output for CI or other tools
- you prefer plain functions over class-based test suites

## When to avoid
- you want built-in mocking, snapshot testing, or watch mode
- you prefer a batteries-included framework like Jest or Vitest

## Facets
- artifact type: library
- maturity: stable
