Testing is an integral part of software development process but sometimes it is omitted because of tight budget or the lack of time. And that’s a mistake. While some software bugs may be harmless, other may turn out to be costly and have dangerous outcomes.
That’s why every product should be thoroughly checked before the final release and even after that. Software testing is an ongoing process that is a must in every product that brings value to its users.
What is software testing? Also, what are the types of testing commonly used in software development? What is the software testing life cycle? And lastly, what can you gain from such tests? Learn it all here.
Software testing is the process during which a product team check if the digital product fulfils the expected requirements in terms of security, accessibility, integrity, user experience, and more.
Testing is not only about whether the app is defect free. It’s also about software quality. So, the goal of software testing is to identify bugs, errors, gaps in the code as well as missing user flows. It involves various methods to test the product from different angles to prepare the product for the release.
It’s evaluating an object or system’s behaviour through validation and verification where different types of tests are involved (manual testing, automated testing).
In software engineering, testing can also help businesses assess risks associated with software application implementation in an objective way. It’s an efficient method for identifying and evaluating software quality and its risks and benefits to users.
A rigorous software testing process ensures robust and reliable software operations. Also, testing is essential because it discovers errors before the product is released to the market.
So the sooner you start testing your product, the better. Why? Because as you go on with the process, you’ll have fewer and fewer problems on the way as the process will be iterative.
So what do you get from a well-tested software? Let’s take a look.
Software testing can be used to strengthen the reputation of a business by providing a quality product to the customer. Because of this, software testing becomes an integral part of software development processes.
Probably the hardest test part. Nowadays, with all the sensitive data involved, the focus on app’s security is crucial. Software testing helps protect your products against malware attacks. It ensures their reliability and thus, it’ll be wanted by users since people are always looking for trusted solutions.
Performing tests from the very beginning of software development, helps you save money and time for the long run. Because the earlier you catch some software defects, the less costly it’ll be to fix them.
Thanks to usability tests, the solution is approved by its target audience and it meets their needs. So a well-tested product is a valuable product that users will appreciate and use of. All in all, you get the finest code which translates to a product that customers love. And happy customers mean increased sales.
Before we move on to the common types of software testing, let’s consider the basic levels of software quality – functional and non-functional aspects. So while in the first one it’s about user experience, the second one is more about the solution’s architecture (its portability, maintainability, performance and more).
More about this topic in my other article – How to take care of software quality – the process.
There are a number of ways in which tests can be categorised. I’d like to propose the following categories – code, performance, product and other tests.
In code testing we can enumerate tests such as:
Vercel‘s CEO Guillermo Rauch once wrote: “Write tests. Not too many. Mostly integration.”. This is really deep and really useful advice. And yet, sometimes, it’s neflected by developers.
For most projects you should write automated tests – especially when you value your time. It is better to catch and fix a bug locally that to break production.
When you thrive for 100% code coverage you spend time testing things that don’t need testing at all. The worst thing that can happen in this approach is testing implementation details. The key to good tests is the thought that you should very rarely have to change tests when you refactor code. As easy as that.
Integration tests are a great balance between confidence they bring and speed/expense. While end-to-end tests give you the most of confidence that your app works as intended, but are slow and expensive (to maintain and to run).
What you should think about during software testing is not the code itself but rather the use cases that the code supports. Thanks to this, you’re going to write tests just like your target audience uses the app.
Before you start testing you app, sit with your team, make a list of functionalities and prioritize them. Thanks to this, you’ll have a great base for all your tests. Start with end-to-end testing and cover the „happy path” (the path the majority of users face for a certain use case). And even though, the e2e tests won’t give you 100% use case overage, they’re great base for software testing process.
Design for lean testing. In other words, make your testing process easier by creating a short, simple and easy-to-work with code. The goal is to make the testing process as simple as possible so that the process wouldn’t be daunting for the team. Who has time for that? Testing code should be easy and efficient.
The perfect quality assurance process should be automated. Every change, every alteration made in the code is tested as an integral part of CI setup. Nothing untested goes into production.
And what is the best way to perfom automed tests? In the CI/CD pipeline. In fact, this is how we do it at Gorrion. We’re always include tests in CI/CD pipeline thanks to which we ensure the highest quality of the app at all times.
Software testing is an important part of every software development process. Because behind every good product stand multiple tests. These include usability tests and load tests that are a part of the application audits that we perform during our software development process. Apply for the audit and let’s get your app up and running in no time!
