10 Advanced Techniques for Testing with JavaScript Frameworks in 2023

Application testing is one of the most crucial processes in the app development lifecycle as it helps the developers to ensure that they’re providing the intended end-user experience to their customers. The testing process also helps the developers to ensure that the application is devoid of any critical bugs and errors that can cripple its performance. 

In the modern app development market, various tools, plugins, platforms, and frameworks assist developers during the application testing process. For instance, automation testing and JavaScript frameworks are two of the most important additions to the present app development market. 

Developers can integrate both of these practices to further elevate their app development environment. These integrations also help the app developers to improve the quality of the final application.

With this article, we will focus on some of the most advanced techniques that can help testing teams improve their experience with modern JavaScript frameworks. We will also understand how the integration of various platforms and tools can improve the efficiency of an application test bench.

Understanding JavaScript Frameworks and Automation Testing

These are some of the most advanced frameworks that can help developers to execute continuous application testing processes with the help of JavaScript. JavaScript is one of the most popular programming languages that are currently available. 

It is useful for not only the front-end testing processes but also the back-end test cases. It is worth mentioning that JavaScript has held its position for over 20 years in the application development industry. Moreover, due to the reputation of JavaScript, it receives native support in almost all the tools, platforms, and frameworks that are currently available

So, the developers can easily integrate a native ecosystem while working with this programming language. JavaScript is also easy to learn and understand compared to other programming languages in the market.

Since we are on the topic of integrating JavaScript app testing frameworks with automation testing, it is very important to have a basic idea about test automation. 

In simple terms, it is the process of eliminating human involvement in the application testing process. For the replacement process, the system will use a test file that will allow it to interact with the application like a normal user. Based on these interactions, the system can generate a report about the user-friendliness of the app. It also helps the developers to understand whether the application is ready to be released to the open market. 

The app developers can also make significant changes in the test file to make the results suitable and customized according to the requirements. It is also possible to store and reuse automated test files in future app development projects.

However, before transitioning to automated testing practices, the developer should also be aware of the massive drawbacks that come with automated testing. This is because, during the initial stages of this application process, the developers have to invest a significant amount of money in the setup. 

This setup process will consist of the expenses of integrating various plugins, tools, and libraries that are critical for the proper execution of automation testing. So we recommend that app development companies have a proper idea about their business perspectives and possible returns on investment before making the transition.

Advanced Techniques for Testing with JavaScript Frameworks

Various techniques can help app development companies properly utilize their JavaScript testing frameworks. To prevent any confusion or misunderstanding, we have created a list of the best techniques in this category. They are as follows:

1. App developers need to perform integration testing on their web applications. With this form of testing, the developers can verify how the application components interact with each other. The developers can also understand whether any element in the application is responsible for the downfall of the others.
2. Snapshot testing is another important form of application testing that helps developers to remove unintentional errors in the application. In this form of testing, the developers have to take a snapshot of the application at a certain stage of the development process. Then the app developers can compare the snapshot to any other stages of the process to find out any errors or changes. It can help the developers sort out critical bugs in the application that can arise due to unintentional code changes.
3. While working with JavaScript testing frameworks, the developers must perform performance testing on the application. With this form of testing, the developers can verify the performance of the application under various forms of use case scenarios. With this form of testing the developers can understand how the application reacts to various forms of user load, interactions, and traffic.
4. Other than verifying the combined performance of the application elements, the developer should also verify the proper performance of each element present in the application. This form of testing is covered by functional testing. It also helps the developers to find important bugs and errors that can be present in any specific part of the application.
5. While working with JavaScript-based test cases, the developer should also perform end-to-end testing on their web applications. This is because, with the help of end-to-end test cases, the developers can verify not only the individual performance of all the elements present in the application but also their combined performance. It is very important when the developers are working on applications that undergo a continuous updating process. It helps them to understand that none of the new features break the already existing features.
6. In the current state of the app development market, developers need to integrate automation testing with JavaScript testing frameworks. It can help them to eliminate the need for a manual test bench for conducting repetitive test cases. On the other hand, the developers can focus on other creative parts of the app development project. Automation testing also helps to reduce the overall expense of the application development stage.
7. After making any change in the core framework of the application, the app developers need to retest the stability of not only the new features but also the existing ones. This form of testing is often referred to as regression testing and is one of the most critical components of the app development process. The developers can also use automation testing to automate their recognition test cases in the application development process. It can save a lot of time and effort in the app development lifecycle.
8. While using JavaScript testing frameworks, the developer should also verify the security of the application. It is very important to ensure that all the sensitive customer details are in safe hands and there is no possibility of any data breach. It is essential for applications such as banking apps, health apps, and Ecommerce apps.
9. Executing usability testing helps developers to understand the simplicity of a web application. In simple terms, it means that with this form of testing, the developers can ensure that it is very easy to use the application and perform the basic tasks on it. With this form of testing, the developers can massively improve their target audience for the company. It also helps to create a positive image for the brand.
10. While using JavaScript testing frameworks, the developer should include continuous testing in their test bench. With the help of continuous testing, the developers can automatically initiate the test cases whenever there is a change in the code. It also helps to increase the synchronization between the testing and development teams of a company. So, we can say that continuous testing has an indirect role in reducing the development time for the application.

The Integration of Tools and Platforms in Automation Testing

As we already mentioned earlier, various platforms and tools can highly contribute to the simplicity of automation testing practices. Moreover, these tools are very easily available in the market and do not require complex sourcing processes. For instance, cloud platforms help developers to get rid of having an on-site physical device testing lab. On-site physical device testing labs are crucial to verify the influence of physical device parameters on the performance of an application. This is because simulation softwares cannot verify how the application behaves to user interaction errors, low battery, a broken display, or any other such parameters. However, it is a very expensive process to have such a device test bench. On the other hand, cloud platforms help developers to achieve similar test results while executing all the test cases over the Internet.

With the help of cloud platforms, the developers can also initiate and execute test cases from anywhere in the world and remove all forms of geolocation barriers. We can further elevate our knowledge of cloud platform-based app testing by considering LambdaTest as a benchmark:

For the core understanding, we can say that LambdaTest is a modern secure platform to execute cross-browser test cases on complex web apps. Cross-browser testing is the new standard of verifying the highest level of application performance in the modern generation. This is because, with cross-browser test cases, the developers can ensure the app’s stability irrespective of the end user’s change in browser version, operating system, or the complete device specification. This platform also uses parallel test execution to improve the efficiency of the test cases by almost fifteen times. LambdaTest can help developers to work with automation test files from multiple frameworks like Selenium, Playwright, and Cypress. While working with Selenium test cases, it is possible to execute it on more than 3000 unique browsers.

This platform also helps the app developer to verify the performance of locally hosted web apps for the internal operations of a company. Lastly, the integration of multiple real devices with the already present thousands of emulation software helps developers to improve the accuracy of the test results.

The Conclusion

With this article, we tried to spread adequate information about the proper use of JavaScript-based testing frameworks. This is because this information will help the application development companies to utilize the full potential of the testing process. We also discussed the importance of integrating these frameworks with automation testing. Many market experts believe that automation testing will completely dominate the app development industry in the coming years. So, the developers must keep themselves prepared to maintain their company’s position in this competitive market. They should also try their best to keep their knowledge up to date regarding all the new additions and trends in this segment. The app companies can also conduct frequent awareness campaigns to distribute the required knowledge regarding healthy app development practices.
