Are you the one who is considering switching from Selenium to Cypress? Then, this post is for you. Here we have discussed Selenium and Cypress and the differences between the two that would help you move quickly from Selenium to Cypress with ultimate ease.
What is Selenium?
Testers may provide test cycles quicker using the Selenium framework by automating repeated test cases. Selenium can aid with a stable, bug-free release deployment workflow when used with a CI/CD pipeline.
Selenium provides a set of browser automation technologies. It comprises four Selenium components, each of which serves a distinct role for web testers.
- Selenium IDE(Integrated Development Environment)
- Selenium RC(Remote Control)
- Selenium WebDriver
- Selenium Grid
Limitations Of Selenium
Here’s a short rundown of Selenium’s drawbacks:
Selenium demands your team’s skill — as well as resources to manage. The framework requires a lot of maintenance and is difficult to expand as your business grows. A cloud-based lab is safer than the Selenium Grid. Selenium does not provide test visibility via reporting.
1. Expertise And Resources
Operating Selenium and its dependent frameworks require knowledge, expertise, and technical competence. Development and testing teams must be familiar with its architecture to utilize the Selenium framework to its most significant potential. Some teams might face trouble finding the right resources to handle Selenium testing.
2. Inadequate Reporting
When it comes to software engineering, the ability to report is quite helpful. Teams must be able to monitor critical testing information, outcomes, and remedial actions to improve constantly. Testers should also discuss and share their findings. Because Selenium does not enable reporting out of the box, it must be supplemented with external tools.
3. Limited Lab
Selenium provides the “Selenium Grid” as the testing lab. This component of Selenium allows you to run many tests on various browsers, devices and operating systems.
The Selenium Grid requires both trained engineers and IT permission to construct and maintain. Additionally, it is less secure than cloud-based laboratories, which are more versatile and powerful.
4. Scalability And Maintenance
Test maintenance might be complex for test automation engineers when using Selenium. Minor UI changes might cause tests to fail. Maintaining tests with the Selenium framework, on the other hand, takes years of expertise in debugging and preserving such scripts. Selenium enables you to test on almost any browser and operating system. However, the amount of testing time and volume permitted is limited by the number of hub/nodes accessible.
What is Cypress?
Cypress is a front-end testing tool and its goal is to alleviate developers’ and QA engineers’ difficulties while testing an application. Cypress is a more developer-friendly tool. It functions directly in the browser and employs a unique DOM manipulation method. In addition to this, Cypress also offers a one-of-a-kind interactive test runner that performs all instructions. Cypress is fundamentally and structurally different from Selenium.
QAs or developers may use Cypress to create:
- End to end tests
- Integration Tests
- Unit Tests
Testers can now do Test-Driven Development (TDD) with comprehensive end-to-end testing, thanks to architectural enhancements in Cypress. Cypress was created to make development and testing run in parallel.
Features of Cypress:
Cypress offers many features, but the most important ones are mentioned below:
- At the time of test implementation, the Cypress framework takes snapshots. This enables QAs or developers to hover over a command in the Command Log to view precisely what occurred at that point.
- Unlike Selenium, there is no requirement to include explicit or implicit wait instructions in test scripts. Cypress waits for orders and assertions automatically.
- Cypress implements instructions in real-time as they are written by the programmer, delivering visual feedback as they run.
- Cypress comes with a wealth of documentation.
- Developers and QAs may use Spies, Stubs, and Clocks to check and manage the behavior of server replies, functions, and timers.
- Before taking any action, the automated scrolling checks that an element is visible (for example, Clicking on a button)
- Previously, Cypress only allowed Chrome testing. On the other hand, Cypress now supports Firefox and Edge browsers, thanks to recent revisions.
Why Should You Move To Cypress?
Cypress may be used instead of or in conjunction with other web testing frameworks for various reasons. Here are a few of the most important advantages.
1. It’s Easy to Set Up Cypress Automation
Cypress testing for web is simple to get started with and if you have worked with Selenium previously, you will know that you must first pick all of the dependencies and libraries you might require before you begin testing. These particular dependencies and libraries are already installed with Cypress, so there’s no need to configure them.
Furthermore, Cypress includes a Chrome browser, so there is no need to set up a complicated environment. You may also try Cypress with any other browser installed on your local PC. This flexibility and ease of setup are huge benefits compared to Selenium, which needs the user to download an appropriate driver and set up a grid before starting to test.
2. Cypress Is More Adaptable
3. Cypress Is Capable Of Debugging
With Cypress, you can rapidly debug your web projects. When tests fail, you will be advised to address the problem. Hereafter, you may use Chrome DevTools to debug them directly. Cypress also includes features like Time Travel and real-time reloading, allowing developers to see their website code during and after a test run.
Because Cypress has access to every item, error analysis is simplified and streamlined. Cypress can generate pictures of test failures, making detecting bugs and troubleshooting applications a breeze.
4. Cypress Has A Very Active Network
Cypress is an open-source framework. Not only this, it is also free to use. It works on a freemium approach to choose between the free and premium versions. Advanced capabilities include a dashboard containing artifacts, such as DOM snapshots, useful for debugging and video storage in the commercial edition.
5. Cypress Automation Allows You to Run Tests Quickly
Cypress is recognized for its lightning-quick test execution, with response times of under 20 milliseconds. Automatic waiting is incorporated into the Cypress framework, so you don’t have to create implicit or explicit waits. The framework automatically waits for things like DOM loading, animation, elements, and more.
In addition, when the first test is completed, the framework automatically executes the following tests. This reduces downtime and removes the need to initiate the next test manually.
Difference Between Cypress And Selenium
Let’s have a quick insight into the difference between Cypress and Selenium:
- One of the most notable differences between Cypress and Selenium is that Selenium operates in a separate process from the browser or device being tested.
- Cypress has overcome the primary difficulty with Selenium by running it in the same run loop as the device. Cypress is in charge of waiting for DOM components to appear. Cypress will wait for your application to reach this state before proceeding. You’ll never have to bother with retries or manual delays again. Because Cypress waits for objects to exist, it will never send you stale items that have been severed from the DOM.
- Despite the fact that Selenium and Cypress are both designed to automate browsers for testing, their architecture and performance are quite different. Cypress is not only a good Selenium replacement, but it’s also a great way to educate engineers about test automation. This is the reason why Cypress is one of the fastest-growing automation platforms in the world. Selenium is a more all-purpose tool intended towards a broader audience.
Before selecting a Cypress testing tool, it is necessary to weigh the benefits and drawbacks of each option. Spend some time trying a cloud-based platform like LambdaTest, which supports both Cypress and Selenium, to automate a few test cases.
LambdaTest is the fastest-growing cross-browser testing cloud in the world. Over 1Million devs and testers across the globe, LambdaTest ensures that their websites and web apps are displayed flawlessly across all browsers, devices, and operating systems. You may also benefit from live-interactive manual testing and responsive testing and a cloud Selenium Grid of 3000+ browsers.
While using LambdaTest, you may also use a single test session to collect full-page screenshots of your websites in up to 25 different browsers and operating systems. You may also do pixel-by-pixel comparisons using visual regression testing across images of your online application. With this LambdaTest, you can perform Cypress testing across 40+ browser versions on cloud.
