BaseTestData

A powerful utility designed to manage default test payloads and effortlessly modify them on the fly using override, exclude, and only arguments.

Example

import { BaseTestData } from "@pdnsyamkumar/test-utils";

const testData = new BaseTestData();

const defaults = {
  name: "Syam",
  preferences: { theme: "dark", notifications: true },
};

// Override specific fields
const updated = testData.getTestData(defaults, {
  override: { name: "Pdn" },
});

// Exclude nested dot paths
const minimal = testData.getTestData(defaults, {
  exclude: ["preferences.notifications"],
});

override accepts DeepPartial<T>, so nested values can be changed without repeating sibling fields. exclude and only accept top-level keys or nested dot paths (including array indices). Use either exclude or only, not both.

getTestData returns Partial<T>. When selecting or removing a nested path, the returned nested object can be incomplete at runtime; access those nested values defensively.
