How to Write and Run Your First Nightwatch.js Test | Nightwatch.js Tutorial
In the third part of our Nightwatch.js tutorial series, ๐๐๐ฉ๐๐ฌ ๐๐๐ก๐ข๐ค๐๐ซ๐ฒ demonstrates how to write your first automated tests using the Behavior Driven Development (BDD) approach with Nightwatch.js.
You'll learn how to structure test suites with describe blocks, write individual test cases using it functions, and implement setup/teardown hooks like before, after, beforeEach, and afterEach. Additionally, Tapas explains how to interact with web elements, make assertions, and organize your tests professionally for real-world e-commerce testing scenarios.
๐ฏ What You'll Learn:
โ BDD fundamentals and methodology
โ Essential test syntax (describe, it, expect, before, after)
โ Writing real test cases for e-commerce scenarios
โ Element interaction (setValue, click, waitForElementVisible)
โ Assertions and test validation techniques
โ Test execution and HTML report generation
By the end of this session, you'll be able to write, run, and debug your own Nightwatch.js test cases, setting the foundation for comprehensive web application testing.

In this episode of the NightwatchJS series, we dive into setting up NightwatchJS for your project. Youโll learn how to install and configure NightwatchJS for both new and existing projects, define your test folders, page objects, custom commands, and assertions, and understand the purpose of the nightwatch.conf.js configuration file.
We cover running tests on multiple browsers like Chrome, Safari, and Edge, including how to configure Safari for automation on Mac. The session also introduces globals for sharing data across test suites, and environment variables to securely manage sensitive information like API keys.
Finally, we explore single vs. parallel test execution using test workers to speed up your testing, and demonstrate how to run tests on one or multiple browsers in parallel. This session lays the foundation for writing effective NightwatchJS tests in the next episode.
