Suitape

A tiny wrapper for Tape to allow grouping tests in suites, promises support and extend Tape with new assertions.

Example of use:

import { suite, tape, addAssertions } from 'suitape';
import myComponent from 'path/to/my/component';

suite('/path/to/my/component', (test) => {
  test('My component should do its job', (assert) => {
    const actual = myComponent.returnOne();
    const expected = 1;

    assert('equal', actual, expected);
  });
});

Instead of using tape's assetions directly as methods, they should be passed as first parameter of assert function. If an invalid assertion name is provided an error will be thrown.

Extending Tape assertions:

Assertions can be extended using addAssertions function provided by extend-tape module:

import React from 'react';
import { createRenderer } from 'react-addons-test-utils';
import createComponent from 'react-unit';

import {suite, addAssertions } from 'suitape'
import jsxEquals from 'tape-jsx-equals';

addAssertions({ jsxEquals })

import Button from './Button';

suite('path/to/Button', (test) => {
  test('Button should set default className if no one is passed as property', (assert) => {
    const component = createComponent.shallow(<Button/>);

    const actual = component.props.className;
    const expected = 'default-class';

    assert('equal', actual, expected);
  });
});

Promises support:

Similar to blue-tape, if some test returns a promise it's suite won't be finished until all remaining promises are resolved:

import { suite } from 'suitape';
import component from 'component/path';

suite('async/component', (test) => {
  test('This async operation should return expected value', assert => new Promise((resolve) => {
    component.doAsyncOp().then((result) => {
      const actual = result;
      const expected = { id: 1, name: 'Someone' };
      
      assert('deepEqual', actual, expected);
      resolve(); //If resolve isn't called, the suite will never end
    });
  }));

Finally, original Tape can be imported directly from suitape for any purpose:

import { tape } from 'suitape';
