Zero dependency test framework
The implementation is <250 loc, (<500 with comments) ( https://github.com/Raynos/tapzero/blob/master/index.js ) and very readable.
const tape = require('tape') // Tapzero exports an object with a test function property. const tapzero = require('@socketsupply/tapzero').test
tape('my test', (t) => { t.equal(2, 2, 'ok') t.end() }) // Auto ending behavior on function completion tapzero('my test', (t) => { t.equal(2, 2, 'ok') // t.end() does not exist. })
Return a promise. The test will end when the promise resolves.
// tapzero "auto" ends async tests when the async function completes tapzero('my cb test', async (t) => { await new Promise((resolve) => { t.equal(2, 2, 'ok') setTimeout(() => { // instead of calling t.end(), resolve a promise resolve() }, 10) }) })
tapzero('planning example', t => { // this test will fail if we execute more or fewer // than planned assertions t.plan(2) t.ok('hello') t.equal(2, 2, 'two is two') })
No aliases, smaller API surface area
tape('my test', (t) => { t.equals(2, 2) t.is(2, 2) t.isEqual(2, 2) }) tapzero('my test', (t) => { // tapzero does not implement any aliases, very small surface area. t.equal(2, 2) t.equal(2, 2) t.equal(2, 2) })

const test = require('@socketsupply/tapzero').test
Run a single named test case. The fn will be called with the t test object.
Tests run one at a time and complete when the fn completes, the fn can be async.
Like test(name, fn) except if you use .only this is the only test case that will run for the entire process, all other test cases using tape will be ignored.
Creates a test case that will be skipped
const testHarness = require('@socketsupply/tapzero/harness')
