Setup Jasmine BDD testing Framework in Node JS

1. Overview

Jasmine is a BDD framework for testing JavaScript code. It does not rely on any other JavaScript frameworks and aims to run on any JavaScript-enabled platform. Jasmine was originally developed by Pivotal Labs, which is now part of the Cloud Foundry project.

Node JS is a javascript runtime built on Chrome’s V8 engine. Node JS is an open source server environment that runs javascript on the server.

2. Node js download and Nodejs install

Node.js is a free, and one of the open-source JavaScript runtime environment that runs on various platforms, including Windows, Linux, and macOS. Node.js is used for developing server-side applications and networking applications. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient.

Node.js can be downloaded from the official website at There are two versions available – the current version and the LTS (Long Term Support) version. The LTS version is recommended for production environments as it has better stability and support.

Select your Operating system: Windows or MacOs or SourceCode

Check your Operating system resources for 32bit or 64bit

Download and install on latest node version on your PC

3. Jasmine install

Jasmine is a JavaScript testing framework that supports a software development approach known as behavior-driven development, or BDD. Jasmine provides functions to help developers structure their tests and also provides test doubles, spies, and matchers for making assertions about the behavior of code.

Start Installation: npm install --save-dev jasmine

To make initialize a project for Jasmine: npx jasmine init

To seed your first project with some examples: npx jasmine examples

To run your first test suite: npx jasmine

4. Jasmine is a Behavior-Driven Development (BDD) framework

Jasmine is one of the BDD framework for testing Js code by easily describing acceptance criteria in terms of scenarios. It provides the acceptance criteria in terms of scenarios, and it has been designed to use more effectively. Jasmine is one of the open source and can be used in any JavaScript environment.

Jasmine is a BDD framework for testing JavaScript code. Good part is that, it does not depend on any other JavaScript frameworks. It does not require a DOM or it has a clean, obvious syntax so that you can easily write tests fast.

Jasmine is one of the the great choice for unit testing because it is easy to use and easy to extend. Jasmine also has a rich set of features for programmers, such as spies and mock objects, that make it a best choice for behavior-driven programming.

Jasmine used together, describe, it blocks and expect


The describe block is overview of task

The it block is test task title

The expect block is a acceptance criteria.

4. Conclusion

Jasmine is a Behavior-Driven Development (BDD) framework that benefits developers by providing them with a tool to test their code’s output against a set of expectations. By using Jasmine, developers can catch errors early on and ensure that their code is functioning as intended. Additionally, Jasmine makes it easy to create tests that are readable and maintainable.

Node.js is an open source server environment that runs on various platforms (Windows, Linux, Unix, and Mac OS X). Node.js applications are written in JavaScript and can be run within the Node.js runtime on any platform.

Node.js provides a number of benefits over traditional server-side scripting environments.

First, Node.js is asynchronous, meaning that it can handle multiple concurrent requests without blocking or waiting for each request to finish before starting the next one. This makes Node.js very efficient and allows it to scale easily to support large numbers of users.

Second, Node.js has a large and active community that has created a vast ecosystem of modules and libraries that can be used to extend the functionality of your application. This means that you don’t have to start from scratch when building a Node.js application – you can simply use existing modules to add the functionality you need.

Finally, Node.js is fast. It uses Google’s
