TypeScript Unit Test

What is Unit Testing in TypeScript?

Unit testing in TypeScript ensures that individual functions and components work as expected in isolation. Popular frameworks for TypeScript testing include Jest, Mocha, and Jasmine.

Setting Up TypeScript Unit Testing

1. Install Dependencies

For Jest:

npm install --save-dev jest ts-jest @types/jest

For Mocha and Chai:

npm install --save-dev mocha chai ts-node @types/mocha @types/chai

2. Writing a Simple Jest Test

Example of a unit test using Jest:

test('adds 2 + 3 to equal 5', () => {
    function add(a: number, b: number): number {
        return a + b;
    }
    expect(add(2, 3)).toBe(5);
});

3. Running Tests in VS Code

For Jest

npx jest

For Mocha using npm:

npx mocha
