What Are Software Testing Methodologies and Main Types

This article describes different types of testing methods that can be used during the software testing phase.

What Are Software Testing Methodologies

Testing methods are the strategies and approaches used to test a particular product to ensure that it achieves its purpose. They typically include testing whether a product performs according to specifications, does not exhibit unwanted side effects when used outside of its design parameters, and fails, in the worst case, safely. 


On the other hand, Software testing methodologies especially refer to the various techniques and methods utilized to thoroughly test a software product. These include a range of testing practices, such as assessing the software's compliance with its specifications, evaluating its behavior under different conditions, and ensuring that it can safely handle worst-case scenarios. This encompasses a variety of testing practices, such as module-level unit testing, system-wide integration testing, and more specialized areas such as security or performance testing.

Why Software Testing Methodologies Important

With the increasing complexity of software applications and the need to test them on numerous platforms and devices, it is crucial to have a strong testing approach. This will ensure that the software products/systems meet their specific requirements, function effectively in all projected environments, and possesses the required usability and security. Failing to implement appropriate testing and development strategies for modern software can result in exceeding budget, unnecessary delays, and not meeting the needs of stakeholders.

Popular Software Testing Methodology Types

Waterfall Model

In the waterfall model, formal testing is performed in the testing phase that begins after the development phase is completed. The waterfall model for testing is suitable for smaller, less complex projects. However, if the requirements are not clearly defined at the beginning, it is very difficult to make changes again in a completed phase.

The waterfall model is one of the most popular software testing methodologies for smaller projects because it has fewer processes and actors to handle, allowing for faster project delivery. However, bugs are discovered late in development and are more expensive to fix.

Agile Model

The Agile model, unlike the Waterfall model, is best suited for large development projects. Agile testing is an incremental model, with tests running at the end of each increment or iteration. Additionally, the entire application is tested after the project is completed. Agile models reduce risk in the development process because each member of the team understands what has and has not been completed. If you have a strong and experienced project manager who can make decisions quickly, you usually get better results with Agile on your development projects.

Iterative Model

Other SDLC models include iterative and DevOps models. In the iterative model, the developer creates a base version of the software and iterates it in small steps to test and improve the application. This is a good approach for very large applications that need to complete quickly. Defects can be detected early and are therefore cheaper to fix.

DevOps approach and continuous testing

Using a DevOps approach to testing or continuous testing requires collaboration with the operations team throughout the product lifecycle. This collaboration eliminates the need for development and operations teams to wait until the software is built or near completion to conduct tests. This means a faster software delivery process, earlier detection of errors, and lower cost of remediation.

Continuous testing uses auto-testing and automation tools as components of the software development pipeline. Therefore, it can provide immediate feedback on any business risks that may exist.  


The article focuses on what are software testing methodologies and the main types of software testing methods. Generally speaking, Software testing is an extremely necessary part. It usually requires the time and energy of developers. However, People cannot escape from making mistakes. And any small mistake will make the software or application fail to work normally. To save time, an expert in software testing, WeTest, is highly recommended. It provides professional continuous testing tools to save your time and money.
