Testing of any system is important. But when it comes to software, it’s utterly crucial. This is why so much time and effort gets spent on it. It’s much better to find a fault in Testing than it is to have it wreak massive damage once properly in action.

In this piece, we’ll look at 15 of the most important software testing statistics and explain why we believe they are so vital to your understanding of the field.

1. The Software Testing Market Was Worth $45 Billion in 2022

The world of software testing is truly massive and growing at a very steep incline. Research predicts a 5% increase every year until 2032.

This underlines the importance of testing in the software sector. Testing is a priority you shouldn’t ignore, whatever your business does, from online telephone provision to database management.

2. Many Developers Are Involved in Testing

Testing is an activity that an enormous number of developers are busy with. It’s actually reckoned that 43% of developers work in testing. That doesn’t mean that this is all they do. It just means that testing is one of the duties of almost half of all developers.

This means that developers should acknowledge that a degree of testing will form part of their work, and they may well already have completed some in a prior development role.

3. Testing Is an Integral Part of the Development Process

It’s sometimes tempting to think of testing as a separate, discrete process that deploys following development. However, 77% of developers carry out testing concurrently with development, often utilizing libraries like the react programming library to build responsive and interactive user interfaces for web applications. So, wherever development is taking place, testing should be inserted into the process.

And when testing is ongoing, don’t fail to factor in security. Especially when teams can be quite geographically widespread, it’s important to use secure remote access solutions when remote testing is undertaken.

4. Number of Testers

How many testers should your business have? Obviously, this will vary hugely from company to company, but if you have only one, then you’re definitely in the minority. According to Kobiton, 41.6% of companies have a testing team size of 2-10, while 40.2% have 11-25 testers on their books.  

If you’re a small remote team, communication solutions like Vonage telephone services for small business can keep your testing team connected and streamline the development process.

5. The Internet of Things Is Going to Be Huge

Any software testing approach needs to factor in the IoT, which is projected to grow to goliath proportions in the next few years. By 2030, it’s predicted that there will be almost 30 billion IoT devices in the world. That’s about four for every person on the planet. It makes sense to build an IoT focus with testing strategies into your development. 

6. Think Mobile

If IoT is going to be huge, mobile’s already so. This is why so many software testing businesses are directing their efforts with mobile devices in mind. 69.5% of software companies agree that mobile is a critical or at least very important part of their business model.

So, it’s clear that mobile app testing is a major component in the testing sphere and is likely to remain so.

7. Manual Testing Is a Drag

So, testing is a massive business. But it’s a sad truth that many developers find themselves committed to, at times, very slow and tedious manual processes.

This is why 36% of developers report that manual testing is the most time-consuming activity. It seems clear that we should be looking into introducing more automated testing. 

8. Why Pursue Automation?

Automated testing isn’t just about making developers’ lives a little more exciting. There are many benefits that automated testing can deliver. 55% of software companies cite quality of testing as the main reason they employ automation. Time-to-market reduction is also a consideration (30.2%). 

Most of us are familiar with the benefits of automation in general, and it’s no surprise that it can revolutionize testing. 

9. How Many Use Automation?

Here’s an amazing stat: 97% of developers use automation in their testing routines. So, although manual testing is a relatively rare activity, as we’ve seen, it accounts for a disproportionate amount of a tester’s time.

This shows just how potent an enemy of efficiency manual testing is.  

10. Automated Testing Is Set To Grow Hugely

So, given the time-sink that manual testing can be, it should come as no surprise that automated testing is on the up. The automation testing market is predicted to be worth $68 billion by 2025. 

Clearly, AI will be a significant component in automated testing. You can see this reflected in the increase in companies buying AI domain names and promoting the AI aspects of their offerings. So, if you’re not already, it’s time to start looking into what AI can do for your software development process. 

11. Automated Testing Can Be Expensive

OK, so here’s the bad news. Some development teams are shackled because not enough budget is devoted to automated testing. Most businesses are now spending between 10-49% of their testing budgets on automation. So, if you’re spending under that, then you’re likely to lag behind.

12. Automate Testing for Great ROI

But here’s the better news. RPA—Robotic Process Automation—typically gives a 250% ROI. This means, on top of bigger profits, that more resources become available for future development. This is good for team morale and the forward-thinking attitude of the business in general. 

Testing is still sometimes wrongly regarded as wasteful and unnecessary. Rise above these testing myths—testing is a positive investment.  

13. Which Test Automation Frameworks Are the Most Popular?

It might be most sensible to opt for the most widely used test automation frameworks. One study found that 41% of businesses used JUnit and 31% Selenium WebDriver.

14. Which Programming Languages Are the Most Popular in Automated Testing?

When it comes to testing, it’s good to use a language that most developers will know.

A recent study found that the most popular programming languages for test automation were as follows: Java 40%, JavaScript 37%, and Python 37%. No surprises there. 

15. Test or Face the Consequences

A Consortium for Information and Software Quality (CISQ) report found that $2.08 trillion was lost by US companies in 2020 due to poor software quality. Much of this loss could have been avoided with adequate testing. 

There are times when costs can be a special concern, such as when you’re in the initial stage of setting up an ecommerce business, for instance. 

Whether your business deals with ecommerce, mobile applications, IoT devices, or even hotel management software, the initial costs may seem daunting, but once the benefits of testing and early detection of bugs are clear.

Testing is Everything

Software testing statistics point to a number of conclusions. Here are two of them. To introduce a product or service to market without adequate testing is foolhardy, and not using a degree of automation is plain mystifying.

To put it another way: test, and you spot problems before your customer does; use automation, and you can do so with relatively little pain.
