Introduction to NRPRTest

NRPRTest is a powerful testing library designed to help developers efficiently test and monitor APIs across various platforms. With its intuitive design and rich set of features, it can drastically simplify the API testing process. In this comprehensive guide, we’ll introduce NRPRTest and explore its extensive API capabilities with practical examples.

Getting Started

First, let’s initialize a new NRPRTest instance:

  const nrptest = require('nrptest');
  const tester = new nrptest.Tester();

1. Creating a Simple Test

Creating a simple test with NRPRTest:

   tester.test('GET /api/status', async (context) => {
     const response = await context.sendRequest('GET', '/api/status');
     context.assert(response.status).toBe(200);
   });

2. Testing with Query Parameters

How to test an API with query parameters:

   tester.test('GET /api/users?name=John', async (context) => {
     const response = await context.sendRequest('GET', '/api/users?name=John');
     context.assert(response.data).toContain('John');
   });

3. Making POST Requests

Sending data using POST requests:

   tester.test('POST /api/users', async (context) => {
     const payload = { name: 'John Doe', email: 'john@example.com' };
     const response = await context.sendRequest('POST', '/api/users', payload);
     context.assert(response.status).toBe(201);
   });

4. Authentication Tests

Testing endpoints requiring authentication:

   tester.test('POST /api/login', async (context) => {
     const credentials = { username: 'user1', password: 'password123' };
     const response = await context.sendRequest('POST', '/api/login', credentials);
     context.assert(response.data.token).toBeTruthy();
     context.set('authToken', response.data.token);
   });

   tester.test('GET /api/profile', async (context) => {
     const token = context.get('authToken');
     const response = await context.sendRequest('GET', '/api/profile', null, {
       Authorization: `Bearer ${token}`
     });
     context.assert(response.status).toBe(200);
   });

5. Example Application with NRPRTest

Given the APIs above, let’s develop an example application structure to show how these tests can be integrated into a live project:

   const express = require('express');
   const app = express();
   app.use(express.json());

   app.get('/api/status', (req, res) => {
     res.json({ status: 'ok' });
   });

   app.get('/api/users', (req, res) => {
      const users = [{name: 'John'}];
      res.json(users.filter(user => user.name === req.query.name));
   });

   app.post('/api/users', (req, res) => {
     res.status(201).json(req.body);
   });

   app.post('/api/login', (req, res) => {
     const { username, password } = req.body;
     if(username === 'user1' && password === 'password123') {
       res.json({ token: 'fake-jwt-token' });
     } else {
       res.status(401).json({ error: 'Unauthorized' });
     }
   });

   app.get('/api/profile', (req, res) => {
     if(req.headers.authorization === 'Bearer fake-jwt-token') {
       res.json({ user: 'John Doe' });
     } else {
       res.status(401).json({ error: 'Unauthorized' });
     }
   });

   app.listen(3000, () => console.log('Server is running on port 3000'));

In conclusion, NRPRTest offers a streamlined approach to API testing with its rich feature set and intuitive design. By incorporating these testing strategies into your development workflow, you can ensure the robustness and reliability of your APIs. Remember to keep experimenting and adapting API tests based on evolving project requirements.
