Test automation is a method of using specialized tools and frameworks to verify and validate test scenarios. QAs write automated scripts that are put into automation tools that start the app, perform the test scenario, and label whether the test has succeeded or failed. Test automation is only suggested for repeated situations since it saves time and work that manual testers would otherwise have to put in.

The Cypress testing framework has risen in popularity, and it is now generally recognized as an easy to set up and use automation framework. This article will give you insights into the checklist for Cypress Automation Testing and an overview of it.

Cypress Overview

Cypress Automation Testing

Cypress is a contemporary web test automation framework based on NodeJS. The programming language is JavaScript.

The Cypress automation tool may be used for a range of tests, including integration and unit tests, end-to-end tests, API testing, and so on. Cypress also has a number of built-in features to assist developers and quality assurance personnel. Screen capture, video recording, time travel, and simple debugging are just a few of them. Cypress currently supports Edge, Firefox, and Chrome cross-browser testing.

Assertions from Chai and Mocha are used by default in the Cypress framework, therefore testers may utilize assertions from these libraries. One of the most prevalent characteristics of the automation sector is reporting. Internally, Cypress employs Mocha reporters, thus testers may specify Mocha reporters or Spec reporters in their specifications.

Folder Structure Of Cypress

Cypress comes with a folder structure by default. The primary folder is cypress, which has subfolders inside it. The real test scripts are stored in this folder.

  • Fixtures: If you’re utilizing external data in your tests, the Fixtures folder might help you arrange it.
  • Assets: After the test run, a folder named downloads will be generated with screenshots, videos, and other assets.
  • Support: Utility, global commands, commonly used codes, and other items may be found in the Support folder. It contains two files by default: commands.js and index.js. As needed, more files and directories may be added.
  • Plugins: The Plugins folder includes special files that may be used to run code prior to the project loading. Include any pre-processors that your project needs in this subdirectory and configure them appropriately. The index.js file is located in the plugins folder by default, and it may be changed to create your own tasks.
  • Assets: After the test run, a folder named downloads will be generated with screenshots, videos, and other assets.

Basics Of Cypress:

Cypress Automation Testing

  • Introduction and Architecture: Cypress is a cutting-edge front-end testing tool for a contemporary web application. Most testing tools like Selenium function by operating outside of the browser and performing network instructions. However, the Cypress engine runs entirely inside the browser. It allows Cypress to monitor and change browser behavior in real-time by modifying the DOM and changing network requests and answers.
  • Installation Of Cypress And Project Setup: The direct download will always get the most recent version for your OS. This would download a zip file. This zip file has to be extracted by the user. npm may also be used to get it. It also shows how to put up a simple package project. It comes with JSON and Cypress pre-installed.
  • Install Visual Studio Code: Visual Studio Code is a lightweight yet powerful source code editor for Windows, macOS, and Linux that runs on your desktop. Visual Studio Code comes with in-built support for TypeScript, Node.js, and JavaScript. A large network of extensions for additional languages and runtimes including C#, C++, Java, Go, Python, and PHP are also available.
  • Non-Cypress Async Promises To Handle: We know that Cypress manages the asynchronous nature of its commands internally and yet executes the test cases in a smooth, consistent and sequential manner. In spite of this, there may be times when you need to clearly handle commands or promises, like when integrating Cypress instructions with JavaScript commands or third-party libraries.
  • Cypress Test: Tests on Cypress are built on Chai and Mocha as they are one of the most well-known assertion libraries in JavaScript and it uses the same test case authoring methodology as any other framework that is Java-base. In the Cypress Workshop project, you can organize and create test cases using the default folder structure offered by Cypress.
  • Cypress Test Runner: Cypress features a special test runner that enables us to watch instructions run. It also displays the application under test running in real-time.
  • Locators In Cypress: They are the backbone of all automation frameworks for Web-based applications in Cypress. A locator is also an identifier that notifies any automation tool which GUI components such as TextBoxes, Check Boxes, and Buttons must operate. Cypress makes use of locators to recognize the UI element for the application that is under test, using the same principles.
  • Get And Find Commands: Cypress offers two fundamental methods for searching for web items based on locators: get() and find(). Both of these strategies provide almost similar outcomes. However, each has its significance and implementation location.
  • Installation And Setup For Node.js: Node.js is a server-side runtime environment based on Chrome’s V8 JavaScript engine. It’s open-source and completely free, and lots of developers use it throughout the world. It’s a programming environment. Furthermore, it provides everything you’ll need to execute a JavaScript application. Before you start developing your Node.js application, make sure that you must first set up the Node JS framework.
  • Asynchronous Nature Of Cypress: Asynchronous programming is a kind of parallel programming in which a unit of work performs independently. It also informs the caller thread when it fails, progresses, or completes. These applications are, therefore, referred to as “non-blocking.” Basically, you wait for something to complete before moving on to another activity when you perform it synchronously. If you execute anything asynchronously, on the other hand, you may move on to another activity before it finishes.
  • Interacting With DOM Elements: Every UI automation tool has APIs or methods for interacting with web elements, allowing the user to execute the anticipated action on the UI element. Furthermore, such technologies aid in the necessary user trip modeling. Cypress also includes several instructions that may be used to emulate the user’s interaction with the program.
  • Assertions In Cypress: Assertions are basically validation processes that regulate whether or not the provided step in the automated test case was successful or not. In reality, Assertions actually verify that your objects, application, or components under test are in the planned condition. Assertions, for instance, also allow you to examine if an element is visible or has a certain attribute, CSS class, or condition. It is usually advised to include assertion procedures in all automated test cases; otherwise, it would be impossible to determine if the program has achieved the desired state.

Cypress Automation Checklist

Cypress Automation Checklist

1. Selecting Elements

Use cy. contains() with regex for a precise match, and avoids capitalization in CSS since it makes writing tests more complex. If you need to alter some text but don’t want to break the cypress test, you may utilize data-cy selectors, but this should not be your first choice.

2. Permissions For Users

Instead of logging in as a superuser with all access, try logging in as various users with varied permissions.

3. Control Information

As much as feasible, use mock or control test data. This keeps tests from flaking and makes them locally repeatable. Some tests might even go to the extent where the filter tables for a unique name are only used once.

4. Don’t use the word “wait” ().

If an assertion fails, Cypress will attempt the preceding command and so on until the global timeout is achieved. If you need to wait for an operation, you may use assertions like cy. contains(‘Successfully uploaded’) to wait for an element to not exist. should(‘not.exist’).

5. Commands of Cypress

Instead of writing new Cypress commands, you may reuse old ones. Instead of creating additional Commands, we chose to utilize ES6 classes with static methods in this project. Later on, upon introducing Typescript support, this worked better.

6. Do not use {force: true}

Cypress is an automation program that mimics user behavior. The actionable checks are overridden if you use force: true on any event. Cypress uses the default settings, such as visible, exist, and so on. If you attempt to automate without taking into account user behavior, you may find some difficulties afterward since the tests will pass even if the application is not functioning as planned.

True, there are certain circumstances in which you may need to use force: However, you should generally avoid using it. To avoid using {force: true}, you might first assert the parent or surrounding elements before asserting the element itself.

7. Using .eq(), .first(), and similar functions to chain array items should be avoided.

When a large collection of items is provided and you wish to utilize a particular element from that collection, such as the first or last member, you may specify it directly in the selector rather than chaining the instructions with .eq(),.first(),.last(), and so on. There’s a potential you’ll receive an Element disconnected from the DOM problem

Notable Characteristics Or Advantages Of Cypress

Cypress has several top-tier characteristics that provide numerous advantages, including:

  • Cypress takes a photo while your tests are running. One of the game’s changing product characteristics is this. It also allows you to go back in time when it comes to command execution.
  • Clocks, Spies, and Stubs β€” It regulates or checks the behavior of timers, server replies, and functions.
  • Manages Easily manage, test, and debug network traffic without involving your server. You have the ability to stub network traffic anytime you choose or need it.
  • Consistent results are ensured through Cypress. WebDriver and Selenium are not used in the Cypress design. That is why it is the flake-free test that is the most consistent, trustworthy, and fastest.
  • View screenshots are captured automatically on collapse, and videos of the whole test suite are taken throughout operation from the CLI.
  • Cypress is an all-in-one tool. Writing front-end tests necessitates the use of many tools. Cypress may provide you with a variety of tools in one package. To get your test suite configured, you don’t need to install any additional libraries or tools.

Wrapping Up!

Cypress is an open-source and free framework that is broadly regarded as a leading and promising tool. All of these solid features make Cypress a better end-to-end testing framework for both professional quality assurance experts and developers. For these reasons, Cypress is the latest testing tool that is universally applicable and more user-friendly. Cypress has features like automated scrolling, real-time reloads, time travel, lightning-fast implementation, and more that aren’t found in other conventional testing tools.

To conclude, cross-browser testing using the Cypress testing framework can be done at scale using the LambdaTest cloud grid, which is secure, scalable, and dependable that offers you to grow quicker. You can run cypress tests on 40+ browser versions and gain tools that help you run tests and release them quicker. Cypress and LambdaTest integration not only enables you to run Cypress tests on an online automation cloud but also allows you to do cross-browser testing at scale.

On the LambdaTest cloud grid, Cypress test automation includes complete test logs, screencasts (or video captures of executed tests), and more. These are useful resources for troubleshooting existing tests.

Although Cypress is a framework better suited for testing current online applications, it’s giving Selenium automated testing a run for its money. The Cypress testing framework’s capabilities may be further increased by combining it with a dependable cloud-based automation grid.

This is where the LambdaTest Cypress CLI comes in handy since it allows you to run Cypress tests on a variety of browsers and platforms. All of these may be accomplished by performing Cypress parallel testing. Not only is the LambdaTest Cypress CLI simple to use, but it also allows you to run Cypress tests on the LambdaTest Grid without modifying a single line of code logic.
