tst

Tests without efforts.

Gems

• tape-like
• async functions support
• inspectable errors
• correct stacktrace with sourcemaps
• muted skipped
• better colors
• multiple only tests
• start by idle event
• ES export
• test.todo, test.fixme for broken / unfinished tests
• test.node, test.browser - environment conditional tests
• test.demo - demo-run (can fail)
• console.group in browser

Install

or

import t from 'https://unpkg.com/tst?module'

Use

t('these tests will all pass', t => {
	t.ok(true);
	t.ok(true, 'this time with an optional message');
	t.ok('not true, but truthy enough');

	t.is(1 + 1, 2);
	t.is(Math.max(1, 2, 3), 3);
	t.is({}, {})

	t.throws(() => {
		throw new Error('oh no!');
	}, /oh no!/);

	t.pass('ok')
})

t('these tests will not pass', t => {
	t.is(42, '42');
	t.is({}, {x:1});

	t.fail('nok')
})

t.skip('this test will not run', t => {
	t.pass('ok')
})

Creates output in console:

Assertions

• t.ok(a, b, msg?) − generic truthfulness assert
• t.is(a, b, msg?) − assert with equal for primitives and deepEqual for objects
• t.not(a, b, msg?) - assert with equal for primitives and deepEqual for objects
• t.any(a, [a, b, c], msg?) − assert with optional results
• t.almost(a, b, eps, msg?) − assert approximate value/array
• t.same(listA, listB, msg?) − assert same members of a list/set/map/object
• t.throws(fn, msg?) − fn must throw
• t.pass(msg), t.fail(msf) − pass or fail the whole test.
