Umbraco Test Builders

What is it?

The @umbraco/json-models-builders package provides fluent builder classes for creating Umbraco backoffice models. These builders simplify test data creation with sensible defaults and chainable configuration methods.

Installation

npm install @umbraco/json-models-builders

Builder Pattern

All builders follow this pattern:

const model = new SomeBuilder()
  .withProperty(value)        // Configure scalar properties
  .withOtherProperty(value)   // Chain multiple configurations
  .addChild()                 // Create nested builder
    .withChildProperty(value)
    .done()                   // Return to parent builder
  .build();                   // Generate final object

Method Types

Core Builders

DocumentTypeBuilder

Create document types with properties, groups, and tabs:

import { DocumentTypeBuilder } from '@umbraco/json-models-builders';

const documentType = new DocumentTypeBuilder()
  .withName('Article')
  .withAlias('article')
  .withAllowAsRoot(true)
  .withAllowCultureVariation(true)
  .addGroup()
    .withName('Content')
    .addTextBoxProperty()
      .withLabel('Title')
      .withAlias('title')
      .done()
    .addRichTextProperty()
      .withLabel('Body')
      .withAlias('body')
      .done()
    .done()
  .addGroup()
    .withName('SEO')
    .addTextBoxProperty()
      .withLabel('Meta Title')
      .withAlias('metaTitle')
      .done()
    .done()
  .build();

Key Methods :

• withName(name) - Document type name
• withAlias(alias) - Document type alias
• withAllowAsRoot(bool) - Allow at content root
• withAllowCultureVariation(bool) - Enable variants
• AsElementType() - Mark as element type (for blocks)
• addGroup() - Add property group
• addTab() - Add tab
• withDefaultTemplate(template) - Set default template

ContentBuilder

Create content items:

import { ContentBuilder } from '@umbraco/json-models-builders';

const content = new ContentBuilder()
  .withContentTypeAlias('article')
  .withAction('publishNew')
  .withParent('-1') // Root
  .addVariant()
    .withName('My Article')
    .withCulture('en-US')
    .addProperty()
      .withAlias('title')
      .withValue('Hello World')
      .done()
    .addProperty()
      .withAlias('body')
      .withValue('<p>Article content</p>')
      .done()
    .done()
  .build();

Key Methods :

• withContentTypeAlias(alias) - Document type alias
• withTemplateAlias(alias) - Template alias
• withAction(action) - 'publishNew', 'save', etc.
• withParent(parentId) - Parent node ID
• addVariant() - Add content variant

MediaBuilder

Create media items:

import { MediaBuilder } from '@umbraco/json-models-builders';

const media = new MediaBuilder()
  .withName('My Image')
  .withMediaTypeAlias('Image')
  .addProperty()
    .withAlias('umbracoFile')
    .withValue({ src: '/media/image.jpg' })
    .done()
  .build();

Create data types:

import { DataTypeBuilder } from '@umbraco/json-models-builders';

const dataType = new DataTypeBuilder()
  .withName('My Text Box')
  .withSaveNewAction()
  .build();

      .withMandatory(true)
      .done()
    .done()

Rich Text Property
