@push.rocks/tapbundle

A test automation library bundling utilities and tools for TAP (Test Anything Protocol) based testing, specifically tailored for tapbuffer.

Features

• TAP (Test Anything Protocol) compliant output
• Support for both browser and Node.js environments
• Built-in test coordination and timing measurements
• Parallel and sequential test execution
• Pre-task support for setup operations
• Rich assertion library via expect
• Comprehensive Node.js tooling (shell, crypto, MongoDB, S3)

Installation

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

Usage

The @push.rocks/tapbundle is a versatile testing framework compatible with TAP, designed using TypeScript to facilitate robust and scalable testing of applications, whether you are dealing with unit tests, integration tests, or simply need a streamlined way to automate assertions across your application's lifecycle. The framework is especially useful if you are already using or planning to use tapbuffer.

Core API

The main test runner is accessed through the tap object:

tap.test(
  description: string,           // Test description
  testFunction: async (tools?: TapTools) => Promise<any>,  // Test implementation
  modeArg: 'normal' | 'only' | 'skip' = 'normal'          // Execution mode
): TapTest

Getting Started

1. Basic Setup

   First, import the necessary modules:

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

   Start with a simple test:

   tap.test('Initial test succeeds', async () => {
     return expect(true).toBeTrue();
   });
   
   tap.start();

2. Defining and Organizing Tests

   tap.test('basic arithmetic test', async () => {
     expect(1 + 1).toEqual(2);
   });
   
   // Async Tests
   tap.test('async operation test', async () => {
     const fetchData = async () => Promise.resolve('data');
     await expectAsync(fetchData()).toBeResolved();
   });

3. Tools for Advanced Testing

   // Delay and Timing
   tap.test('test with delay', async (tools) => {
     await tools.delayFor(500); // waits for 500ms
     expect(true).toBeTrue();
   });
   
   // Custom Pre Tasks
   tap.preTask('initialize environment', async () => {
     console.log('Setting up preconditions');
   });

4. Execution Control

   // Skip tests
   tap.skip.test('skip this test', async () => {
     // This test will be ignored
   });
   
   // Exclusive tests
   tap.only.test('run this test exclusively', async () => {
     // Only this test will run
   });
   
   // Colored output
   tap.test('test with colored output', async (tools) => {
     const message = await tools.coloredString('Test Passed!', 'green');
     console.log(message);
   });

5. Node.js Integration

   import { tapNodeTools } from '@push.rocks/tapbundle/node';
   
   tap.test('execute shell command', async () => {
     const result = await tapNodeTools.runCommand('ls -la');
     expect(result.exitCode).toEqual(0);
   });
   
   tap.test('create HTTPS certificate', async () => {
     const { key, cert } = await tapNodeTools.createHttpsCert('localhost');
     expect(key).toInclude('-----BEGIN RSA PRIVATE KEY-----');
   });

6. Environment Variables

   tap.test('use environment variable', async (tools) => {
     const dbUrl = await tools.getEnvVarOnDemand('DB_URL');
     expect(dbUrl).toBeDefined();
   });

7. Asynchronous Control

   tap.test('controlled async scenario', async (tools) => {
     const asyncOp = async () => Promise.resolve('complete');
     tools.timeout(1000); // if operation exceeds 1000ms, test fails
     const result = await asyncOp();
     expect(result).toBe('complete');
   });

8. Web Testing

   import { webhelpers } from '@push.rocks/tapbundle';
   
   tap.test('web component test', async () => {
     const element = await webhelpers.fixture(
       webhelpers.html`<my-element></my-element>`
     );
     expect(element.shadowRoot.querySelector('div')).toBeDefined();
   });

9. Database and Storage Testing

   tap.test('Smartmongo setup test', async () => {
     const smartmongo = await tapNodeTools.createSmartmongo();
     await smartmongo.stop();
   });
   
   tap.test('Smarts3 setup', async () => {
     const smarts3 = await tapNodeTools.createSmarts3();
     console.log('Smarts3 running');
     await smarts3.stop();
   });

Best Practices

1. Use descriptive test names that explain the expected behavior
2. Leverage pre-tasks for common setup operations
3. Use testParallel for independent tests that can run concurrently
4. Utilize test coordination for dependent tests
5. Set appropriate timeouts for async operations
