If you’re a QA, you’ve probably heard of a million different types of software testing. More than you could ever want to. There’s unit testing, integration testing, system testing, acceptance testing, performance testing, security testing… the list goes on and on (and on).
It’s enough to make your head spin. And with so many different types of software testing out there, it’s hard to know which ones you actually need to know.
Well, you’re in luck. In this post, we’re going to break down the types of software testing that QAs actually need to know. We’ll cover everything from the basics of functional and non-functional testing to the nitty-gritty of performance and security testing (plus the best ways to automate with ContextQA).

Functional vs. Non-Functional Testing: What’s the Difference?
Before we dive into the different types of software testing, it’s important to understand the difference between functional and non-functional testing.
Functional testing is all about making sure that your application does what it’s supposed to do. It’s about testing the features and functionality of your application to make sure that they work as expected.
Non-functional testing, on the other hand, is all about making sure that your application works well. It’s about testing the performance, security, and usability of your application to make sure that it’s fast, secure, and easy to use.
The Types of Software Testing You Actually Need to Know
Now that you know the difference between functional and non-functional testing, let’s dive into the different types of software testing that you actually need to know. Here’s a quick rundown:
| Type of Testing | What it is | What it’s good for |
|---|---|---|
| Unit Testing | Testing individual units of code | Making sure that your code is working as expected at the lowest level |
| Integration Testing | Testing how different units of code work together | Making sure that your application is working as expected at the component level |
| System Testing | Testing your entire application as a whole | Making sure that your application is working as expected from end to end |
| User Acceptance Testing (UAT) | Testing your application with real users | Making sure that your application is meeting the needs of your users |
| Performance Testing | Testing the speed, scalability, and stability of your application | Making sure that your application is fast, scalable, and stable |
| Security Testing | Testing the security of your application | Making sure that your application is secure from attack |
| Usability Testing | Testing the usability of your application | Making sure that your application is easy to use |

How to Choose the Right Type of Testing
So, how do you choose the right type of software testing for a given situation? Here are a few tips:
- Start with the basics. If you’re just getting started with testing, start with the basics: unit testing, integration testing, and system testing. These three types of software testing will give you a solid foundation to build on.
- Don’t forget about your users. Once you’ve got the basics down, don’t forget about your users. User acceptance testing is a great way to make sure that you’re building a product that your users will love.
- Think about your risks. What are the biggest risks to your application? Are you worried about performance? Security? Usability? Once you know what your biggest risks are, you can choose the types of software testing that will help you mitigate those risks.
