E2E Testing

End-to-end tests are located in the src/e2e directory.

Build and Run E2E Tests#

Watch mode (for development)#

npm run e2e

This command builds and executes the e2e tests. If you modify a file and save it, the code is rebuilt and the tests are run again. This is particularly useful in development: you do not need to re-run the command every time you make code changes.

The process runs forever until you stop it.

Simple mode (for CI and Git hooks)#

If you need to build and run the tests only once, you can use these two commands:

npm run build:e2e # Build the e2e tests code (compile the typescript files and copy the templates)npm run start:e2e # Execute the e2e tests from the built files

These commands are particularly useful when you want to integrate your tests into a CI pipeline or a Git hook.

The SuperTest library#

You can use the SuperTest library to write your e2e tests. It is installed by default.

Example:

// 3pimport { createApp } from '@foal/core';import * as request from 'supertest';import { createConnection, getConnection } from 'typeorm';
// Appimport { AppController } from '../app/app.controller';
describe('The server', () => {
  let app;
  before(async () => {    await createConnection();    app = createApp(AppController);  });
  after(() => getConnection().close());
  it('should return a 200 status on GET / requests.', () => {    return request(app)      .get('/')      .expect(200);  });
});
