Redux Testing

Redux Testing uses JEST as a testing engine.
We can use vitest as a test runner if we are using vite to build a project.
Syntax to install Jest:

npm install --save-dev jest

A basic example of testing using jest :

In product.js:

function product(a, b) {
  return a * b;
}
module.exports = product;

In product.test.js:

const product = require('./product');

test('multiply 1 * 2 to equal 2', () => {
  expect(product(1, 2)).toBe(2);
});

On run command npm test

PASS  ./product.test.js
✓ multiply 1 * 2 to equal 2 (5ms)
