Motivation

Born from a project where full-featured testing frameworks placed unwanted restrictions on a test.

Principles

• Test small scripts with small testing frameworks, test large projects with large testing frameworks.
• Failing a setup or teardown function should fail the whole program, but not the test.
• Scoping is the responsibility of the engineer.
• Ordering is the responsibility of the engineer.
• Failing fast means better tests. Proactive testing is better.
• More emoji is better than less emoji.

Installation

# NPM
npm install --save-dev slither-js

# YARN

Usage

import Slither, { pass, fail } from 'slither-js';

Slither.setup('Setting things up', () => {
  // Do some setup stuff

Slither.test('Testing things', () => {
  // Call pass() or fail()
});

Slither.teardown('Clean stuff up', () => {
  // Undo the setup
});
