Ghost Data Factory

A minimal test data factory for Ghost e2e tests, written in TypeScript.

Setup

This is part of the Ghost e2e test suite. All dependencies are managed by the main Ghost monorepo.

1. Start Ghost development server (provides database):

   yarn dev
   

2. Configure database connection (optional - uses Ghost's database by default):

   cp e2e/data-factory/.env.example e2e/data-factory/.env
   # Edit .env if using different database credentials
   

3. Build the e2e package (includes data-factory):

   cd e2e && yarn build
   

Usage

In Tests

// Import from the built files
const {PostFactory, KnexPersistenceAdapter} = require('../build/data-factory');

// Set up
const db = knex(dbConfig);
const adapter = new KnexPersistenceAdapter(db);
const postFactory = new PostFactory(adapter);

// Build in memory (not persisted)
const draftPost = postFactory.build({
    title: 'My Draft',
    status: 'draft'
});

// Create and persist
const publishedPost = await postFactory.create({
    title: 'My Published Post',
    status: 'published'
});

Running Tests

# From e2e directory
yarn test:factory

# This will:
# 1. Build the TypeScript files
# 2. Run Playwright tests in the data-factory directory

# Or manually:
yarn build
yarn playwright test data-factory

Development

Build Process

• TypeScript source files (*.ts) are in e2e/data-factory/
• Compiled JavaScript (*.js) goes to e2e/build/data-factory/
• The e2e/build/ directory is gitignored
• Always rebuild after making changes: cd e2e && yarn build

Adding New Factories

1. Create a new factory class extending Factory<TOptions, TResult>
2. Implement the build() method
3. Set name and entityType properties
4. Export from index.ts

Example:

export class UserFactory extends Factory<Partial<User>, User> {
    name = 'user';
    entityType = 'users';
    
    build(options: Partial<User> = {}): User {
        // Generate test data
    }
}

Notes

• The test file (test/post-factory.test.js) is JavaScript because it's a standalone script
• All factory code is TypeScript and must be compiled before use
• The compiled files in e2e/build/ should never be committed to git
