Description

Instructions

A small test case for a login page function in the task file (TypeScript) file that checks whether a user can log in with valid credentials. Write the test case in a test framework of one's choice.

Requirements:

• Use a mock or similar techniques for any external dependencies (e.g. a database or authentication service).
• Check for both positive and negative cases
• Use descriptive test method names and comments to explain the test case.

Tools

For the assignment, I chose a set of widely known and well-supported tools:

• Mocha - Test framework running on Node.js;
• Chai - Assertion library;
• Sinon.JS - Mocking framework;
• Sinon-chai - A set of custom assertions for Sinon.JS of custom assertions for Chai.
• ts-mocha - A wrapper on top of mocha that simplifies setup and running tests with ts-node

Running

Node.js v14-v16 is required to run the code

• Run npm i to install all required dependencies
• To build the code, execute npm run build
• To run the test suite, call npm test
