Tehanu-tenbo NPM

Test in Browser

Runs test suites written with tehanu in a browser. Experimental.

Synopsis

sum1.test.js:

import test from './node_modules/tehanu/dist/suite.min.mjs?name=sum1'
import './node_modules/tehanu-repo-tape/dist/index.min.mjs'
import { equal } from './node_modules/tehanu-teas/dist/index.min.mjs'
import sum from './sum.js'

test('one number', () => equal(sum(1), 1))

sum2.test.js:

import test from './node_modules/tehanu/dist/suite.min.mjs?name=sum2'
import './node_modules/tehanu-repo-tape/dist/index.min.mjs'
import { equal } from './node_modules/tehanu-teas/dist/index.min.mjs'
import sum from './sum.js'

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

Running tenbo *.test.js or tenbo sum1.test.js sum2.test.js allows executing some or all test suites.
