Testing apps and products for quality and performance is an integral part of the app development life cycle. While manual testing was the go-to process many years ago, automated testing is the new norm. With advanced automated testing tools, such as Selenium, Cypress, and LoadView, businesses the testing process of their software applications and ensure the quality before it gets to the end users.
However, businesses must exercise caution and carefully evaluate the numerous app testing automation tools available to select the most suitable one for their needs and requirements.
That’s why we have done extensive research and carefully compared the top three web app testing automation platforms—Selenium, Cypress, and LoadView—to help you make the right choice that aligns with your unique requirements.
Selenium – A Closer Look
Selenium, a popular testing framework, enables users to automate web browsers for testing purposes across various programming languages and operating systems.
There are three tools in the larger Selenium ecosystem. They are:
- Selenium WebDriver: Most users prefer to use Selenium WebDriver, which helps automate web browsers for testing. Using various automation scripts, it simulates user interactions, such as clicking on links, filling out forms, and navigating through pages that normal users carry out.
- Selenium Grid: This tool helps users delegate testing across multiple machines to reduce testing time and improve software efficiency.
- Selenium IDE: Selenium IDE is less potent than Selenium WebDriver. However, it runs quick tests. In addition, it also records tests that can be played back later.
Advantages of Selenium
Selenium offers many benefits for testers. Here are the top benefits of using Selenium:
- Cross-Browser Compatible: Selenium framework is suitable for testing web apps across multiple browsers, such as Chrome, Microsoft Edge, Safari, Mozilla Firefox, etc. This feature is handy for developers as it ensures that web apps perform seamlessly across browsers.
- Support for Multiple Languages: Selenium provides support for multiple programming languages. Testers can create and execute test cases using popular programming languages like Python, Ruby, Java, and C#, allowing them to work with the language they are most familiar with.
- Extensive Automation Capabilities: Selenium offers extensive automation capabilities for web applications. It allows testers to automate various aspects of web testing, including interaction with web elements, navigating through web pages, handling different alerts, and managing cookies.
- Efficient Handling of Dynamic Web Elements: Selenium uses methodologies like explicit and implicit wait, dynamic locators, and Page Object Model (POM) to handle dynamic web elements. This enables users to improve test performance by automating web UI testing from the root node.
- Open-Source Framework: Selenium is an open-source tool without any license fee. It offers flexibility, allowing users to customize and extend its functionalities to suit their needs.
- Strong Community Support: Selenium boasts a large community of developers, testers, and users who constantly contribute to the framework. As a result, users can rely on an extensive library of tutorials, resources, and forums for support and assistance.
Disadvantages of Selenium
Although Selenium has many benefits, it also has some disadvantages. Here are some drawbacks of Selenium:
- It is Challenging to Master: Mastering the Selenium framework can pose challenges for beginners, particularly those with limited prior experience in programming languages.
- Lack of Documentation Features: Selenium boasts a strong tech community for support. However, users may encounter challenges due to a lack of documentation for certain features, which can hinder their ability to fully utilize this tool’s capabilities.
- Compatibility Issues with New Browser Versions: As web browsers are constantly updated and evolving, Selenium may not always be fully compatible with the latest browser versions. This can result in unexpected behavior, errors, or failures in Selenium scripts, requiring developers to update their code or wait for Selenium to release updates to address compatibility issues.
- Lack of Mobile Testing Capabilities: Selenium is primarily designed for testing web applications on desktop browsers, and it does not provide built-in support for testing mobile applications on different mobile platforms such as Android and iOS. This limitation means that Selenium may not be ideal for organizations or teams that require comprehensive mobile testing as part of their software testing strategy.
Selenium Use Case Examples
Selenium is used by many top brands worldwide to streamline their testing processes. Some notable examples include:
- Google: Google leverages Selenium to test most of its web applications, such as Gmail, Google Maps, and Google Search. Selenium helps ensure the reliability and performance of these critical applications.
- Netflix: Netflix utilizes Selenium to rigorously test its OTT (Over-The-Top) offerings across multiple devices and browsers. This ensures that users can enjoy a seamless streaming experience.
- LinkedIn: LinkedIn also employs Selenium to thoroughly test and automate various features of its professional networking app, including its ads and feed-sharing functionalities. This helps maintain the quality and functionality of the app.
- HubSpot: HubSpot, a popular marketing automation and CRM platform, uses Selenium to thoroughly test its web applications and products. This allows HubSpot to deliver a reliable and user-friendly experience to its customers.
Cypress – A Deep Dive
By directly integrating into the browser, Cypress allows faster and more effective debugging of test cases, enabling testers to identify and resolve issues quickly.
Cypress can be the ideal tool for testers who value quick test results and efficient debugging. Its unique approach and seamless integration into the browser make it a powerful choice for modern web application testing, providing an improved testing experience for developers and testers alike.
Advantages of Cypress
- Simple User Interface: Cypress has an intuitive and simple interface that makes it easier for testers to create and run tests quickly.
- Provision of Real-Time Feedback: Cypress allows developers to gain feedback on the test results quickly. This means that developers can adopt quick strategies and means to address errors.
- Fast-Performing: Cypress is a fast-performing tool that allows businesses to test their web apps quickly and reduce the time to market.
- End-to-End Testing: With Cypress, developers can test full web application flow from user experience, performance, and compatibility to the database.
- Integrated Debugging: Developers can debug the web application from the browser itself, expediting the testing and debugging process.
- Open-Source: As an open-source testing framework, it is free to use. It has a huge community of developers and users who make the community a knowledge hub for everyone using the tool.
Disadvantages of Cypress
There are several limitations associated with Cypress, which include the following:
Limited Browser Support: Cypress works only on Chromium-based browsers such as Google Chrome, Opera, Microsoft Edge, etc.
Lack of Mobile Testing Capabilities: Cypress is primarily designed for web application testing and does not have built-in support for testing mobile applications, such as mobile websites or mobile apps.
Long Learning Curve: Cypress can be challenging for beginners due to its steep learning curve. As a result, it may require developers and agencies to invest additional time in mastering the tool.
Limited Online Community Support: Cypress’s online community support is currently limited, making it challenging for users to find comprehensive resources and assistance to tackle problems while using the tool.
Cypress Use Case Examples
Cypress, a popular end-to-end testing framework, is utilized by several major companies to enhance their testing processes. Some notable examples include:
- Slack: Slack uses Cypress to test its messaging platform, ensuring seamless communication and collaboration for its users across multiple devices and browsers.
- Autodesk: Autodesk leverages Cypress to test its suite of design and engineering software, verifying the reliability and performance of its applications to deliver optimal user experiences.
