To make high-quality software, the ideal software testing process is a whole-systems approach that combines different testing techniques. Any application’s testing can be broken down into two main categories: “Operability” and “Efficiency.” Functional testing takes care of “operationality,” and performance testing takes care of “efficiency.”
Functional Testing checks a software system’s individual functions and how they work together to see if they meet certain standards that have already been set. It checks for functional accuracy, subsystems’ ability to work together, and compliance with standards that have already been set, taking into account both functional and business requirements.
Performance testing services are a non-functional testing method that stresses a system and then checks its response time, stability, scalability, speed, and reliability in a production-like environment.
In this article, we’ll look at how Performance testing is different from Functional testing.
Why is the Performance Test useless?
Performance testing is an essential part of running a business well and making sure that end users are happy. If your websites, apps, and other systems aren’t reliable enough, people will notice, which could hurt your business goals in a big way.
Performance testing is done for three main reasons, which we’ll look at in more depth below:
- Keeping computers from crashing
- Getting response times that are good
- Mitigating scaling risks
- Keeping computers from crashing
Without a doubt, the worst thing that can happen to a business is when a lot of people use their systems at the same time.
Website downtime incidents are not only bad for customer trust and loyalty, but they can also be bad for your finances. Crashes are bad not only because they waste time and money, but also because they could hurt your company’s reputation.
Before a website goes live, good performance testing tries to find and fix problems that would otherwise cause it to crash.
- Getting response times that are good
Similarly, as technology standards continue to rise, users’ ability to wait for websites to load is getting much worse. According to research done by Google, if a website doesn’t load in 5 seconds on a mobile device, the chances of the user “bouncing,” or leaving the site to look for something else, go up by an average of 106%.
Again, good Performance Testing works to reduce this risk by making sure response times are fast, and the user experience is streamlined as a whole. In the end, this means more online traffic for your business and a higher chance that people will buy from you.
- Mitigating scaling risks
Lastly, as your business grows, new customizations and ways for systems to talk to each other could slow down performance. Applications should be able to grow, and their performance needs should be met for a long time. Manual regression testing is one way to solve this problem, but it is often slow and needs to be closely watched to make sure the results are useful.
When Performance Testing is set up as an automated solution, these problems are found as the application grows. This means that fixes can be made quickly and tests can be kept for future use. You don’t have to worry about the risks that come with growing your business, so you can focus on other parts of it.
WHY IS IT IMPORTANT TO TEST FUNCTIONALITY?
Functional testing services are an important part of any release, whether it’s a new website or an update to an app.
Simply put, functionality testing looks at how your application works to make sure it does everything it should.
Getting this test done is important to the success of your product as a whole. This is why:
- It makes sure a product works the way it’s supposed to.
When a customer gets a product, they expect it to work the way it was said it would. Functionality testing makes sure that a piece of software works as it should when it gets to the end-user by checking each of its functions.
- From the user’s point of view, a functionality test is done.
A program must be tested to see how it would work in the real world. This is done by testing from a customer or user’s point of view during functionality testing. This makes sure that customer needs, like buttons or links that work, are always met before an app is given to a customer.
- It looks at each part to make sure it works well with the others.
In any application, the weakest point is where different parts come together to do a certain task. By looking at each of these parts separately, functionality testing can find any weak spots in the integration points and fix them before the product goes out to customers.
