Top Practices and Tools For Testing React Applications

One of the most widely used front-end libraries today is react, and for a good reason. It has emerged as a top option for web developers worldwide thanks to its modular design, reusable components, and quick rendering capabilities. However, developers must ensure that their React applications are adequate. Tested to ward off any potential defects or problems because great power comes with great responsibility. We will talk about the best methods and resources for testing React applications in this blog article.

Why Test React Applications?

The process of developing software must include testing. It enables developers to find potential faults and problems before they are implemented. Which can ultimately save time, money, and hassles. Several factors make testing React apps so crucial, including the following:

1. Catching Bugs Early: You can find faults and problems in your React application early in the development phase, before they have a chance to reach the production environment, by testing it. Future time, money, and hassle savings may result from this.
2. Ensuring Quality: By testing your React application, you can ensure it is well-made and adheres to your specifications.
3. Increased Confidence: You can improve your trust in your React application’s ability to function as intended by testing it, enabling you to decide whether to release it.

Best Practices For Testing React Applications

1. Write Testable Code: Writing testable code is one of the most crucial things you can do to make testing your React application easier. This entails building reusable components with a modular design that can be tested separately from one another.
2. Use Test-Driven Development (TDD): In the test-driven development method, developers create tests for their code before developing any actual code. By using this method, you can make sure that your code complies with your requirements and find errors and problems early on in the development process.
3. Test User Interactions: Any React application must include user interactions. To verify that your application functions as intended, make sure to properly test user interactions.
4. Use Mock Data: You can insulate your application from external dependencies and increase the reliability of your tests by using mock data in them.
5. Use Code Coverage Tools: You can use code coverage tools to find portions of your application that are not being tested and to make sure that all of your code is covered by your tests.

Tools for Testing React Applications

1. Jest: Testing React apps frequently make use of the JavaScript testing framework Jest. It has capabilities like code coverage and mocking and offers an easy-to-use interface for writing tests.
2. Enzyme: React has a testing tool called Enzyme that makes it simple to test React components. It offers a variety of testing tools for user interactions, state management, and component rendering.
3. Cypress: A potent end-to-end testing tool for online apps is Cypress. It enables you to test your application in various circumstances and mimic user interactions.
4. React Testing Library: A lightweight tool for React called React Testing Library offers an easy-to-use interface for testing React components.
5. Puppeteer: A Node.js library called Puppeteer offers a high-level API for managing headless Chrome or Chromium. It may be used to test web applications from beginning to end.

Conclusion

To make sure React applications are of good quality and satisfy your needs, testing them is essential. You can simplify and improve the effectiveness of testing your React application by adhering to standard practices and utilizing the appropriate tools. Whichever tool you decide to use—Jest, Enzyme, Cypress, React Testing Library, or Puppeteer—be sure to utilize it because it will help you meet your testing objectives.

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

• Performance: It delivers optimal performance.
• Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
• UI design: React Native enables you to design simple and responsive UI for your mobile app.
• 3rd party plugins: This framework supports 3rd party plugins.
• Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

• Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
• Near-native user experience: React Native provides several native components, and these are platform agnostic.
• The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Top 10 Automation Testing Tools: 2020 Edition

The demand for delivering quality software faster — or “Quality at Speed” — requires organizations to search for solutions in Agile, continuous integration (CI), and DevOps methodologies. Test automation is an essential part of these aspects. The latest World Quality Report 2018–2019 suggests that test automation is the biggest bottleneck to deliver “Quality at Speed,” as it is an enabler of successful Agile and DevOps adoption.

Test automation cannot be realized without good tools; as they determine how automation is performed and whether the benefits of automation can be delivered. Test automation tools is a crucial component in the DevOps toolchain. The current test automation trends have increased in applying artificial intelligence and machine learning (AI/ML) to offer advanced capabilities for test optimization, intelligent test generation, execution, and reporting. It will be worthwhile to understand which tools are best poised to take advantage of these trends.****

Top 10 Mobile Performance Testing Tools

Challenge for brands: how to offer a seamless, fast, and user-friendly mobile experience?

App users have a low tolerance for slowness, with a reported 43% of users unhappy if they have to wait longer than three seconds for an app to load. ([App Samurai])

It’s not enough to ensure that your mobile app functions properly, but also to test how it behaves on different devices, under heavy user load, different network connections, etcetera. It’s equally important to test different metrics on both the client-side as well as the server-side. This is where finding the right tool or set of tools for mobile performance testing is essential.

After extensively researching, I’ve put together a list of top-rated mobile performance testing tools and provided an overview of each below.

Top Security Penetration Testing Companies

Cybercrime is one of the world’s fastest-growing threats, with malicious actors constantly elaborating their methods of undetectable intrusion. According to Verizon’s Business 2020 Data Breach Investigations report, there has been a 100% increase in web app breaches, and stolen credentials were used in more than 80% of these cases. These statistics are worrying for many businesses that actively move their processes to the cloud and deal heavily with customers’ personal data.

Under these circumstances, companies need to run regular automated and manual tests to determine weak spots in their infrastructure, software, network and physical perimeter security. One of the most efficient testing methods is security penetration testing, or pentesting.

Pentesting is a benign hacking attempt, manual or automated, to break into the system and uncover its vulnerabilities before actual cyber criminals do it. This method is directed at testing the system security controls for their real-world effectiveness. It involves such stages as data collection, threat modeling, vulnerability scans, penetration tests, and so on.

To get proactive with their cyber security protection, many businesses cooperate with professional security testing companies that are able to comprehensively check the system, identify risks, fix vulnerabilities, and stay one step ahead of potential hackers.

The ranking criteria for security testing companies

When asking a professional software testing company to check your system’s security, in most cases you need to grant them access to sensitive information. For this reason, it’s important to choose a reliable company with an exceptional reputation, which will become your trusted partner.
