Teston

Test runner similar to tape, but with ES6 module support, simpler subtest syntax and nice indentation.

Oh, and Teston is blazing fast, of course!

Installation

You can install the production version via npm.

npm i teston

Or you can install the development version from git, providing it is installed.

git clone https://github.com/testonjs/teston.git

Usage

Teston has an easy to use api, which you should be familiar with if you have ever worked with Mocha.

import t from 'teston';

t('Testing things', (t) => {
  t('Test A', (t) => {
    t.plan(1);
    t.pass('Works!');
  });

  t('Test B', (t) => {
     t.plan(1);
     t.pass('Works!');
  });
});

The output of the above code when passed to Teston would be:

node --experimental-modules test.mjs

 Testing things

  Test A
   Works!

  Test B
   Works!

 All tests passed! 

API

t

t(description: String, test: Function)

The main function for creating a test. You may also call this function when inside a test, which is called a subtest.

t.plan

t.plan(count: Number)

Define how many tests there will be.

t.pass

t.pass(message: String)

Pass the current test with an optional message which will be logged to the console.

t.fail

t.fail(message: String)

Fail the test, passing a message that will be logged to the console.

t.ok

t.ok(value : Boolean, message : String)

Pass if value is truthy, fail if not.

t.notOk

t.notOk(value : Boolean, message : String)

Pass if value is not truthy, fail if is.

t.equals

alias: t.equal t.equals(a: *, b: *, message: String)

Assert that a and b are equal.

t.deepEqual

alias: t.deepEquals t.deepEquals(a: *, b: *, message: String)
