Testing Utilities

Description

The Testing Utilities package provides common functionalities for writing and executing tests in JavaScript projects. It includes assertion methods for comparing values, checking truthiness and falsiness, as well as a method to run multiple test cases and output the summary.

Installation

You can install the package via npm:

npm install <package-name>

Usage

const TestingUtils = require('testing-utils');

// Example test cases
TestingUtils.runTests([
  () => {
    TestingUtils.assertEquals(2 + 2, 4, "Adding 2 + 2");
  },
  () => {
    const arr = [1, 2, 3];
    TestingUtils.assertTruthy(arr.length === 3, "Checking array length");
  },
  () => {
    const name = "John";
    TestingUtils.assertFalsey(!name, "Checking if name is defined");
  }
]);
