Cypress is a popular open-source testing tool that is used by many organizations to automate their testing processes. By automating browser operations, test automation technologies like Cypress and Selenium are used to test the functionality of web applications. Cypress is a relatively new tool in the test world, although Selenium has been a commonly used tool for many years.
In spite of Cypress being recently introduced, it has gained significant traction.
- The Cypress framework takes pictures while the test is running. In the Command Log, this enables QAs or developers to hover over a specific command to view exactly what occurred at that particular stage.
- Unlike Selenium, test scripts don’t require explicit or implicit wait commands. Cypress automatically waits for commands and assertions.
- Spies, Stubs, and Clocks can be used by developers or QAs to check for and manage server replies, functions, or timer behaviour.
- Before taking any action, the automated scrolling function makes sure that an element is visible (for example Clicking on a button)
- Only Chrome testing was previously supported by Cypress. Cypress now offers compatibility for the Firefox and Edge browsers given recent updates.
- Cypress runs instructions in real-time as the programmer types them, showing visual feedback as they do so. Cypress comes with top-notch documentation.
Although Selenium and Cypress are both developed to automate browsers for testing, their architecture and performance are very different. One significant distinction is that Cypress is a handy tool for exposing developers to test automation rather than just serving as a Selenium alternative. As a result, Cypress is one of the automation tools with the highest growth rates across the globe. Selenium, on the other hand, is a tool with a broader audience in mind and is more general in nature.
Cypress is preferred over Selenium when one need:
- Component, API, end-to-end, visual, accessibility, and performance testing in a single framework
- Test execution capabilities for video recording
- The Cypress Single Programming language across development (Front end) and Automation have out-of-the-box retry capabilities for operations performed over elements, reducing flaky tests.
- Early-stage development capability to mock/stut requests and responses
- Save time by using Cypress’s stable, ready-to-use Framework rather than creating your own from scratch with Selenium because it comes with everything wrapped up and ready to use.
- Test Runner has the ability to return back in time to each individual step and attach before-and-after screenshots to debug errors
- When any test fails, there are meaningful exceptions.
Despite significant limitations in its functionality, Cypress still has a lot to offer. Here are some reasons why a QA engineer should become familiar with Cypress:
Continuous testing is the technique of executing tests automatically as part of the software development cycle in order to find and repair bugs as soon as possible. By executing tests each time code is uploaded to a repository or deployed to a staging environment, Cypress can be used to automate this process. This enables businesses to shorten their software development cycles and detect flaws early in the development process.
In order to save time and decrease the need for manual testing, test automation involves using tools and scripts to automate the process of executing tests. Cypress is a great pick for this task since it offers a variety of capabilities that make it simple to create and execute automated tests. The ability to run tests simultaneously, support for a number of test frameworks and an accessible user interface are all included.
Artificial intelligence and machine learning
In order to automate challenging tasks and enhance the precision of test results, artificial intelligence (AI) and machine learning (ML) technologies are being employed more frequently in testing. In order to benefit from these technologies’ features, Cypress can be integrated with them. An AI-powered testing tool might be used, for instance, to generate test cases or forecast which tests are most likely to find flaws.
Shift-left testing is the practice of bringing testing up front in the software development cycle in an effort to identify and correct bugs as soon as possible. By enabling developers to create and execute tests early in the development cycle, Cypress can be used to promote this technique. As a result, testing will take less time and money for businesses to complete.
Cloud-based testing platforms such as LambdaTest allows testers to perform Cypress testing across 3000+ browsers, OS and device combinations. In order to scale testing efforts and save infrastructure costs, cloud-based testing includes employing cloud computing resources to perform tests. In order to benefit from the adaptability and scalability of cloud computing, Cypress can be used in conjunction with cloud-based testing platforms. Due to this, businesses may be able to run numerous tests simultaneously and simply scale up or down their testing efforts.
Overall, Cypress is a powerful tool that can be used to support a wide range of testing trends. Whether you’re looking to automate your testing process, take advantage of AI and machine learning technologies, or scale your testing efforts to the cloud, Cypress can help you to do it efficiently and effectively.
