How Has Software Testing Changed Over the Years

The IT infrastructure is a progressive industry and has evolved a great deal over the last decades. As software development, in particular, continues to evolve, sohave the tools, techniques and options for testing.

Unlike before, when developers did testing manually, automated testing has now made it increasingly easier to optimize applications and machines for your desired metrics even before launch. This has unlocked countless growth opportunities for businesses that depend largely on software development.

In this automation testing guide, we’ll explore some of the changes that software testing has experienced over the years and how they benefit the industry.

Mobile Applications Testing Has Changed a Great Deal

As of 2019, there were over 592 million daily app downloads. However, the user retention rate for mobile applications stood at around 30%.

If these figures are anything to go by, engaging and retaining users is even more important than getting your app downloaded. As such, software developers need to emphasize delivering in-app experiences that delight users consistently.

This is best achieved through software testing, which helps ensure that every element, page, or feature of your app aims to move the user down the conversion funnel. But this hasn’t been an easy feat for years when software testing was manual.

Today, it is possible to automate software testing with emulated or real devices. That means software developers can now deliver delightful in-app experiences in virtually all aspects of a mobile application. These include installation, functionality, performance, network usage, security, and battery usage. As a result, mobile applications can be optimized to fit users’ needs as it is now easy to figure out what works for your mobile app and what doesn’t, even before you launch the app.

Cloud Automated Testing

The transition to the cloud is another invention that has significantly affected how software testing is done. A few years back, software developers were confined to the scope and size of the development environment. It was not easy to get a real peak load before launching any new application. But that’s all in the past.

For instance, in a cloud environment, it is now easy to simulate a real-world scenario for better performance testing. This ability to scale the test environment as needed has also made it easy to execute testing throughout the software development lifecycle.

Besides, it’s now possible to test from any part of the world. This, in turn, gives you a sneak preview of how users in various locations will access and interact with the new application before launch.

Automated Web Services Testing

A few years back, it was not easy to verify that all Application Programming Interfaces (APIs) exposed by your web service operated as required. Even a large quality assurance team with an automation testing guide had a rough time performing a controlled web application test with just a few hundreds of users.

With the advent of automation testing tools that can simulate thousands of virtual users, that’s no longer the case. Today, it is quite easy to test various web services elements, including response data validation, response time, transaction volume, security, and scalability. Consequently, it has become easier to ensure acceptable performance, security, and scalability metrics between dependent software and web applications.


For years, bug problems have always been vague and insufficiently understood issues. That explains the reason why delivered software almost always had defects even after going through thorough manual tests.

But that’s now coming to an end with the advent of automated software testing. It is now easy to deliver optimized solutions that offer better user engagement, retention, and conversions.
