@push.rocks/tapbundle

tap bundled for tapbuffer

Install

Install the package by running the following command in your terminal:

npm install @push.rocks/tapbundle --save-dev

This will add @push.rocks/tapbundle to your project's devDependencies.

Usage

The @push.rocks/tapbundle package is a tap-compatible testing framework written in TypeScript, intended for use with tapbuffer. It includes a range of useful features enabling easy setup and execution of tests, assertion handling through expect and expectAsync, as well as auxiliary tools for delay and colored console output.

Getting Started

First, ensure your project is set up with Typescript and supports ESM syntax. You can then import tap, expect, and expectAsync from @push.rocks/tapbundle to start defining your tests.

import { tap, expect, expectAsync } from '@push.rocks/tapbundle';

Here is a simple test example:

import { tap, expect } from '@push.rocks/tapbundle';

tap.test('should succeed on true assertion', async () => {
  return expect(true).toBeTrue();
});

tap.start();

Defining Tests

You can define tests with descriptions and async functions. The tap instance manages test execution, supports test skipping, and managing exclusive tests with the .only modifier.

const myTest = tap.test('expect true to be true', async () => {
  expect(true).toBeTrue();
});

const skippedTest = tap.skip.test('this test is skipped', async () => {
  // This will not be executed
});

tap.only.test('only this test will run', async () => {
  expect('TapBundle').toContainString('Tap');
});

tap.start();

Using expect and expectAsync

The package provides expect and expectAsync for assertions:

await expectAsync(Promise.resolve(true)).toBeResolved();
expect(5).toBeGreaterThan(2);

Handling Asynchronous Operations

tapbundle facilitates working with async operations in tests. You can introduce delays or set timeouts:

tap.test('async operation with delay', async (tools) => {
  await tools.delayFor(2000); // Wait for 2000 milliseconds
  expect(true).toBeTrue();
});

tap.start();

Advanced Usage

Pre Tasks

You can define tasks to run before test execution begins:

tap.preTask('setup database', async () => {
  // Perform setup here
});

tap.test('test database connection', async () => {
  // Test the setup
});

tap.start();

Accessing Test Metadata

Each test returns a TapTest instance, from which you can access metadata and manipulate test behavior:

const test = tap.test('metadata example', async (tools) => {
  tools.allowFailure();
  expect(true).toBeTrue();
});

tap.start().then(() => {
  console.log(`Test duration: ${test.hrtMeasurement.milliSeconds}ms`);
});

Running Tests

Tests are executed by calling tap.start(). This method runs all defined tests in sequence and respects .skip and .only modifiers.

Debugging and Output

@push.rocks/tapbundle supports colored console output via consolecolor to help with debugging and test result readability:

tap.test('colored output', async (tools) => {
  const coloredString = await tools.coloredString('Hello, world!', 'green');
  console.log(coloredString);
});

tap.start();
