Test withoutefforts.

• no tooling, vanilla ESM
• works both node/browser
• async functions support
• inspectable errors
• stacktrace with sourcemaps
• clean l&f in browser/node
• supportsassert,chai etc.
• minimal, 0dep
• tape API

importtest,{ok,is,not,throws}from'tst.js'test('tst demo test',()=>{ok(true);ok(true,'this time with an optional message');ok('not true, but truthy enough');is(1+1,2);is(Math.max(1,2,3),3);is({},{})throws(()=>{thrownewError('oh no!');},/ohno!/);})

• test.only − run only selected test(s)
• test.mute − run test(s), mute assertions
• test.skip − bypass test(s)
• test.todo − bypass test(s), mark as WIP
• test.demo − demo run, skip failed assertions.

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

Testing should not involve maintaining test runner.
It should be simple astap/tape, working in browser/node, ESM, with nice l&f, done in a straightforward way.
I wasn't able to find such test runner that so I had to create one.
