Take On Cypress Automation Tool — Discoveries & Comparison
Cypress: A Free Thinker In Test Automation
What I Discovered
There are two categories of testing in the world of software — manual and automation. Test automation is the practice of running tests automatically, managing test data, and utilizing results to improve software quality and it will make software applications bug-free. It’s first and foremost a quality assurance measure, but its activities necessitate the commitment of the entire software development company.
We all know the big changes made by Selenium in test automation -now it’s time to move on to new tools. In this blog, we are going to discuss Cypress.io which is now considered as an alternative to Selenium for writing the tests and infrastructure. There are some of the advantages that I captured from my method:
- Easy to read the code (and tests)
- Very modular and maintainable code
- It’s pretty easy to diagnose the root cause of failure
Cypress Automation Tool
Cypress is a JavaScript-based framework for end-to-end testing. Cypress tests anything that runs in the context of a browser. It involves everything needed to test modern web apps, and hold up for multiple browsers. Users create a test file in the editor tool to automate the software application and test the outcomes in a website running live in a browser. Cypress records videos and saves screenshots as it goes to ease the debugging process.
This fascinating determination about Cypress really surprised me. I thought that it works one way, while in fact, it works in a completely different pattern which was new to me.
Cypress vs Selenium
We can compare Selenium and Cypress from many viewpoints, there’s one key difference between the two i.e, Selenium is a library but requires a unit for assertions library to build out its capabilities. Cypress provides a strong, complete framework for running automated tests but takes independence out of Selenium by enclosing the user to specific frameworks and languages. This means that in Selenium you must integrate it with other tools, like a testing framework (e.g. Jasmine), reporting, registering, and a lot of other stuff to create your entire solution. For masses of these integrations, you need to write the code yourself and then need to feed it. Cypress, on the other side, attempts to give you everything single thing you need to start working on and relieves you to focus on the tests themselves. By default, they build a mocha framework in cypress

Cypress Features:
Time Travel: Snapshots of the application can be taken when the tests are running. At each step test, developers can hover on each command to see what happened in the Test Runner panel.
Debuggability: Developer Tools that are familiar are used to debug the test directly. The readable errors and active stack traces make troubleshooting/debugging lightning fast.
Automatic Waiting: It instinctively waits for commands and assertions in cypress before proceeding; there is no need to use explicit waits/sleeps to your tests.
Spies, Stubs, and Clocks: These are used to verify and manage the behavior of functions, server responses, or timers in run time which are similar to unit test cases.
Network Traffic Control: Response of the API calls can be customized and also can stub the network traffic using cypress as per your need.
Consistent Results: Cypress is fast, consistent and tests are flake-free also Cypress doesn’t use Selenium or WebDriver to run the tests in the browser directly.
Screenshots and Videos: It takes screenshots automatically on failure, or records videos of your entire test suite when running from the CLI.
Faster Execution: Using DOM events cypress performs in-browser execution directly. Say it sends a click command directly to the button. Test duration time and resolution changes, pass/fail, browser migration.
1.Setting up tests(Installation)
Repository: https://github.com/navya1096/Cypress
2.Writing Your First Test
3.Testing Your Application
Step 1: Enter the npm command in the terminal to open the cypress server
Step 2: Start and visit your server
(i) It should look something like http://localhost:8080.
(ii) Visit the cypress application
Step 3: Test Runner
Advantages of Cypress:
- Fast execution and setup
- Open-source software
- If there are any changes that have been done to the test it automatically reloads Test Runner.
- Rich Documentation
- Reliable Testing
- Assertions
- Visualization of the running commands and tests
- Helps you finding a locator
- Ease to Debug when compared to other frameworks
- Earlier Cypress supported only Chrome testing. However, with recent updates, firefox and edge browsers are supported in cypress.

Conclusion:
Cypress is a powerful web test automation tool for testing modern web applications. The use of powerful in-built commands allows for the testing of all types of web elements. After you've gotten used to cypress, you can decide to keep all of these factors in mind and notice that you're more productive than before. People are still getting trained on Cypress and finding new things about it every day. Few things excite while others still displease. Focus on what’s important to you. I guess that most things in life are a deal…
