Testing is a crucial factor in the software development life cycle to ensure the efficacy of an application. For that, companies embrace various software QA testing methodologies to check whether the application complies with end-user requirements or not.
As a project manager, you are always keen about the quality of the product and always leverage various QA testing methods to make sure that your product stands out in the marketplace.
As the cost of the development depends on the number of errors and timely completion of the project, you have to identify bugs and fix them according to their priority and severity. However, carrying out various testing methodologies remains a mounting challenge for companies with limited budgets and testing teams with lack of advanced skills.
Considering the software QA testing methods, we have manual and automation testing methodologies to verify an application’s performance under various scenarios. The right software application QA testing strategy allows you to identify and resolve bugs in the early stages before they become fatal and costly.
Here, we will discuss various software application testing strategies that promise you a better product with improved performance.
Software application QA testing methods:
Primarily, software testing is classified into two categories
- Manual software testing
- Automation software testing
They have a significant impact on application quality and improving productivity at different stages of application development.
1. Manual testing method:
Manual testing is a traditional software application QA testing methodology in which test cases are executed manually by a tester without any tools. For this, the testing engineer must have sound knowledge about how the application works, its scope, and the architecture.
It is the primitive step that any company follows to identify and fix errors in the application. Apart from resolving bugs, the manual testing methodology checks the feasibility of your application for automation testing. Despite its efficiency, manual testing is a time-consuming and resource-intensive approach that most SMEs can not afford.
2. Automation testing method:
Every process across the organization is undergoing automation to save time, cost and become productive. Testing is not an exception to it. With the advent of technology, companies are adopting automation testing methodologies to speed up product delivery.
In this approach, QA engineers conduct test cases, manage test data, and utilize it to improve the application’s performance
The problem is not that testing is the bottleneck. The problem is that you don’t know what’s in the bottle. That’s a problem that testing addresses.

Functional vs non-functional software testing:
Apart from manual and automation software testing methodologies, we have functional and non-functional software application testing types to ensure the developed software project is bug-free and easy to use. Let’s have a look at various models in these two testing methods.
Functional software application QA testing:
It involves testing every functionality of a software application. Here, the QA tester provides appropriate inputs and verifies the output against the functional requirements.
Here are the top 7 functional testing methodologies companies follow to identify and resolve bugs on the go.
1. Unit testing:
As the name suggests, unit testing is a way of verifying an individual or a group of connected units within the software. In this, the software project testing expert feeds with sample input and checks its corresponding output. Further, it helps in improving project performance at the unit level.
2. Integration testing
Enterprises run on various software applications, and they have dependencies to deliver a product. For that, organizations need to check the integration feasibility between software and hardware modules.
Integration testing is a process of testing interconnected modules to ensure everything is working synchronously to produce a combined output. This software application QA testing is a part of both black-box and white-box testing methods.
3. Sanity testing:
Software development is an evolving process. Therefore, it is essential to test every time you release a new version of the software. The sanity testing method checks whether the latest version is working or not. If it fails in the first stage, then the product is insufficiently reliable for later phases.
4. Smoke testing:
Smoke software testing methodology covers the most crucial functionality of the system. With smoke testing, you can verify whether the software is stable or not to proceed with further testing. It is also known as confidence testing, where you can verify whether the important features are working or not. This is helpful whenever the new functionalities are developed or integrated with the existing system.
5. System testing:
You can not restrict your application to a single platform until your users are limited. System testing is a kind of black-box testing where the entire software is tested for various platforms. It includes security testing, recovery, stress, and performance testing. Here testing experts check the software functionality for given inputs as mentioned in the requirements document.
6. Regression testing:
Software application development is a continuous process and needs regular testing. Regression testing ensures the software is compatible with new updates and there are no new vulnerabilities with modifications.
7. Acceptance testing:
Acceptance testing will be carried out at the client’s end to ensure the developed software comply with the market trends and meets customer requirements. The client accepts the software when it meets their business goals.
It’s hard enough to find an error in your code when you’re looking for it; it’s even harder when you’ve assumed your code is error-free.

Non-functional software application QA testing:
Non-functional software project testing is a method of checking how a system operates rather than its functional behavior. It includes stress, usability, performance, security, and load testing. Let’s have a look.
1. Performance testing:
After application development, performance testing is a must to check whether the application meets requirements or not. Performance testing ensures the functionality of the application under different loads using various tools.
2. Load testing:
This test helps to know how effectively the software can handle the load during extreme conditions. As your business scales, the software should be adaptable and ready to handle loads accordingly.
3. Stress testing:
Stress testing is used to verify the system’s stability and reliability. Especially it checks device robustness and error handling under extremely stressful circumstances.
4. Security testing:
Despite the project’s complexity and scalability, security is imperative to build trust among customers. Any vulnerabilities in the software lead to massive destruction and data loss. So, the security testing phase ensures your software is free from security threats and intrusions.
5. Usability test:
It is a part of black-box software application QA testing to test the customer’s performance competency. In this phase, you can test whether the GUI is user-friendly or not and the customer navigational experience.
No amount of testing can prove a software right, a single test can prove a software wrong.
Software testing is still a daunting task for many SMEs. There is always skepticism around QA testing. Download this free PDF to know the top myths and facts about software QA testing.
