Provides a set of assertion methods compatible with the built-in assert module usable in both Node.js and the browser.

const test = require('tehanu')('sum'),
      { equal } = require('tehanu-teas'),
      sum = require('./sum'),
      test = tehanu('sum')

test('two numbers', () => equal(sum(1, 2), 3))

You can install the assertion library using your favourite Node.js package manager:

npm i -D tehanu-teas
yarn add -D tehanu-teas
pnpm i -D tehanu-teas
