Factorial Calculator Testing

This repository contains a TypeScript project designed to test the functionality of a factorial calculator. The project is structured into three main components: an API endpoint class which targets the factorial calculator of a https://qainterview.pythonanywhere.com/ , a factorial calculation function, and a suite of tests using Playwright.

Overview

The project aims to ensure that the factorial calculator operates correctly across a range of inputs, specifically integers between 10 and 100. It includes a TypeScript class for interacting with the API, a function to calculate factorial values, and automated tests to validate the calculator's responses against expected outcomes.

File Structure

• ApiEndpoint.ts: Defines the ApiEndpoint class for making POST requests to the /factorial endpoint. It validates input and sends a factorial calculation request.
• factorialCalculator.ts: Contains the calculateFactorial function that computes the factorial of a number, supporting large integers by returning results in scientific notation if necessary.
• factorialTests.spec.ts: Playwright test suite that includes tests for specific, random, and all integers in the range 10-100, ensuring the API and calculator function correctly.
