A simple, lightweight API testing framework built with TypeScript, Supertest, and Mochawesome reporting.

• TypeScript support for better development experience
• Supertest integration for HTTP API testing
• Mochawesome HTML reporting
• Simple, clean architecture
• Built-in assertion helpers

npm install

import { BaseTest } from '../helpers/BaseTest';
import { AssertionHelpers } from '../utils/AssertionHelpers';

class MyAPITest extends BaseTest {
  constructor() {
    super({
      baseURL: 'https://api.example.com',
      timeout: 5000
    });
  }
}

describe('My API Tests', () => {
  let apiTest: MyAPITest;

  before(() => {
    apiTest = new MyAPITest();
  });

  it('should get data', async () => {
    const response = await apiTest.get('/endpoint');
    AssertionHelpers.expectStatus(response, 200);
  });
});

• get(endpoint, headers?)
• post(endpoint, body?, headers?)
• put(endpoint, body?, headers?)
• delete(endpoint, headers?)
• patch(endpoint, body?, headers?)

• AssertionHelpers.expectStatus(response, expectedStatus)
• AssertionHelpers.expectProperty(response, property, expectedValue?)
• AssertionHelpers.expectArrayProperty(response, property)
• AssertionHelpers.expectContentType(response, contentType)
• AssertionHelpers.expectHeader(response, headerName, expectedValue?)
• AssertionHelpers.expectBodyContains(response, substring)
• AssertionHelpers.expectErrorMessage(response, expectedMessage)

# Run all tests
npm test

# Run tests in watch mode
npm run test:watch

# Build the project
npm run build

Set the API base URL using environment variables:

export API_BASE_URL=https://your-api.com
npm test

Test reports are generated in the reports/ directory with both HTML and JSON formats.
