Testing.js

Description

Testing.js is a lightweight JavaScript testing library that provides a simple and intuitive way to write and run tests for your JavaScript code. It allows you to define test cases with custom assertions and provides informative output about test results.

Installation

You can install Testing.js via npm:

npm install testing-library-js`

Usage

To use Testing.js in your JavaScript projects, simply import it into your test files:

const Testing = require("testing-library-js");`

Example

You can define tests using the it() method, which takes a name for the test and a test function:

const testing = new Testing();

testing.it('should return true for positive numbers', () => {
    testing.expect(5).isNumber().isGreaterThan(0);
});

testing.it('should return false for empty strings', () => {
    testing.expect("").isString().toBeFalsy();
});

Matchers

Testing.js provides a variety of built-in matchers for common assertions:

• isNumber(): Asserts that the value is a number.
• isString(): Asserts that the value is a string.
• equalsTo(expected): Asserts that the value equals the expected value.
• isGreaterThan(expected): Asserts that the value is greater than the expected value.
• isLessThan(expected): Asserts that the value is less than the expected value.
• toBeTruthy(): Asserts that the value is truthy.
• toBeFalsy(): Asserts that the value is falsy.

Running Tests

After defining your tests, you can run them using the runTests() method:

testing.runTests();

This will execute all the defined tests and display the results in the console.
