Overview

Represents an attribute that generates data structures dynamically.

This class provides generation functions like array that can create collections of arbitrary size with evaluated values. It's useful for testing batch endpoints or generating large payloads.

Examples:

Generate an array of static values

generate.array:
  size: 5
  value: "test"

Generate an array with faker values

generate.array:
  size: 100
  value: "{{ faker.string.alphanumeric }}"

Generate an array with sequential indices

generate.array:
  size: 3
  value: "user_{{ index }}"
# Produces: ["user_0", "user_1", "user_2"]

Combine faker with index

generate.array:
  size: 10
  value: "{{ faker.internet.username }}_{{ index }}"
