Java or JavaScript: What to choose for QA Automation on AWS Projects

Today, almost all companies striving to achieve their desired success need to release high-quality software as quickly as possible. But can manual software testing be useful here? Unfortunately not. Test automation is something that can help organizations accelerate product release cycles in addition to improving software quality.

Amazon Web Service (AWS) supports several popular programming languages ​​such as Java, Python, Ruby, PHP, Node.js, JavaScript framework, and more. All of them ​​are useful and offer different features, communities, support, and ecosystems. So, if you need automated testing for your AWS product and want to choose between Java or JavaScript, keep reading for some important tips to help you make the right choice.

General Concepts About QA Automation

QA Automation provides:

  • Speeding up the process of checking and releasing large projects;
  • Detection of defects at earlier stages of the software development life cycle;
  • Reducing the risk of detecting software errors in the production environment;
  • Reducing the time and money spent on manual testers.

The software test automation market offers special tools and technologies that ensure fast product delivery. It includes performing static code analysis, functional testing, and performance testing using automated test scripts.

Also, by replacing manual work with automated tests, the total cost of software testing is reduced. Therefore, you will be able to obtain a high return on investment.

Automation Testing For AWS Project

It will be tough to perform automated testing without the necessary tools, so you should make an informed choice. Of course, changing one structure to another is very risky. However, you need to understand that each language has its syntax, error handling, and program execution. 

Java

Large companies highly regard Java from Oracle Corporation.

It’s one of the safe languages ​​designed for high performance and has a wide range of supported open source libraries and frameworks.

The perfect combination of Java Unit with Selenium WebDriver can enhance automatic browser testing capabilities for websites or web applications. Since there are many open-source frameworks developed using Java, this is one of the most suitable test scripting languages.

It’s also worth noting that Java applications on AWS have the following benefits:

  • Reliable and well-tested libraries

Almost all Java libraries are reliable for creating a supportive environment for users.

  • Platform independence

Java plays nicely with various tools like Eclipse, IntelliJ IDEA, Maven, and Gradle.

  • High performance

Thanks to the use of Just-In-Time compilers, the language provides fairly high performance. You can easily determine the amount of memory a program needs, making its performance predictable.

Java has unique characteristics such as multithreading, platform independence, security, and object orientation. These benefits help you run Java-based web apps on various AWS services such as Amazon Simple Storage Service (S3), and Amazon Elastic Compute Cloud (EC2).

JavaScript

One of the snags in JavaScript is its dynamic type. If you are used to coding in strongly typed languages, you might find it a little odd to see how these runtime values ​​get or change their type.

Another distinction is the language features. JavaScript uses functions instead of methods. There are anonymous (unnamed) and arrow functions (lambdas).

The third difference is that JavaScript has scope variables called var and block scope variables like let or const.

The last characteristic is the execution of the event loop and the Promise objects representing the final completion of the operation and its final value.

The advantages of cloud-hosted serverless apps are undeniable: less complexity, faster time-to-market, and more effortless scalability than traditional, server-dependent projects. And with JavaScript support in AWS Lambda and robust serverless API tools such as the Claudia.js library, you can continually create and deploy serverless applications without learning a new language.

But, if you still need more information, there are a considerable number of resources that can help you with JavaScript:

Learn JavaScript. A helpful resource for students and is translated into four languages. You might think the material is quite outdated, but it still gives you a valuable knowledge base.

GitHub. This site offers a large selection of e-books that describe non-standard solutions and interesting JavaScript approaches.

JavaScript. Everything is simple; this is the necessary language documentation.

The Right Choice

In most cases, companies tend to change tools, but the problem is often the teams and their skills. However, if the most experienced professionals assemble your business, the projects have a better chance of success.

Analytical thinking, quick adaptation to different types of technologies, and the ability to choose the right technology stack for a project make engineers and testers genuinely famous. Your automation professionals need to successfully support any scripting language and scale tests as efficiently as possible while developers integrate testing into the development process.
