What is Test Methodology? (With 7 Methodologies)

By Shormistha Chatterjee, Community Contributor -

Testing goes hand-in-hand with preparation, designing, and executing the code; treating it as an isolated procedure would be wrong. 

  • It enhances software app performance, security, and quality assurance.
  • It boosts software efficiency and improves Test Automation ROI
  • On the flip side, not testing in the early hours results in poor software quality and exacerbates issues that aren’t only expensive and time-taking. 

However, it is not as easy as using a  testing tool and running the app to mitigate the errors. Following an effective test methodology early in the SDLC and adopting a testing infrastructure like Browserstack could help you identify and solve defects. 

So, what are different testing methodologies, and what distinctions does it make to your apps? This article focuses on the pioneer software development methodologies that are universally accepted and used by companies across the globe.

The Need for Software Testing Methodologies

Software testing methodologies forms the backbone of reducing testing cycle time in the following manner

  • Every testing methodology provides productive solutions that ensure a software project meets the business necessities and manages the user experience.  
  • QA testing methodologies are pivotal, giving a sense of direction of why and how testing should be executed.
  • Directs organizational structure, project management, and the implementation of testing techniques.
  • Software testing methodologies handle your project requirements, bugs, issues, and test cases in a sole integrated environment, with complete traceability throughout the test lifecycle.
  • It is an inclusive testing solution that counts requirements management, release management, test case designs, defect tracking, and many others from day one.

What is Test Methodology?

Software Testing methodologies are the approaches and strategies used for testing a precise product to make sure it is fit for purpose. It generally entails testing that the product functions along with its specification, has no unwanted side effects when used in modes outside of its design parameters, and the most horrible case, will fail safely.

Some well-accepted testing methodologies comprise – Waterfall model, Agile methodology, iterative model, verification and validation Methodology (V-Model), Spiral Model, Extreme Programming Model, RAD (Rapid Action Development) Methodology, and many others.

Let’s explore the different types of testing methodologies below. 

Waterfall Model

This model for testing works perfectly for small, less complicated projects and is built on a team’s step-by-step growth during the test procedure. As it has fewer players and procedures to tend with, this can result in speedy project completion. But, bugs are found at later phases, making them extremely costly. 

One of the key benefits of this methodology is that it is comparatively easy. The drawback is that the QA’s wouldn’t be able to make quick corrections to the test procedure, as it is regimented.


  • Used to plan & managing project requirements easily.
  • Speedy project implementation in QA testing methodologies.


  • This model is a predefined methodology and can’t be skipped.
  • Even a slight modification in the methodology can bear excessive expenses.

Use Cases

  • HRMS (Human Resource Management systems)
  • CRMS (Customer Relationship Management systems)
  • Point of Sale systems
  • IMS (Inventory Management systems)
  • Supply Chain Management systems

Agile Model

The Agile model is dissimilar from the waterfall methodology and is well-suited for big development projects. 

  • An agile test is an incremental model where tests are executed at the end of each iteration or increment. 
  • It can cover the sphere of tests and software development, and marketing.
  • The outcomes are better with agile methodology when an experienced and strong product manager can make rapid decisions. 

Besides, the complete app is ideally tested at the end of the project. There is a lesser threat in the development procedure with the agile technique as every team member understands what has not or has been completed.

You might also hear about a famous working model named Scrum. It is a part of the agile model and is also based on sprints. Every sprint in Scrum concludes with a review meeting wherein QA members examine progress and plan future test sprints.




  • Complicated app processes can be managed, changed, and tested without problems. 
  • Incremental testing reduces the cost and threats related to numerous changes.


  • An inferior planning priority can result in document inefficiencies. 
  • Increased to & fro with customers may result in extended delivery times.

Iterative Model

In the iterative methodology, software developers form basic versions of the software and review & enhance the app in iterations— smaller components or steps. Itl is data-driven, and all iteration is based on the outcomes of the previous test cycle. 

This is a perfect approach for large apps that must be finished rapidly. Errors can be noticed earlier, making them less expensive to resolve.




  • Smaller iterations for complicated software lessen development costs and time.
  • In contrast to the documentation, this methodology provides extra flexibility and concentrates on design.


  • General communication overheads significantly increase after every feedback iteration 
  • The iteration cycle is stiff and does not be overlapped.

Use Cases

Verification and Validation Methodology (V-Model)

The Verification and Validation method is considered an extension of the waterfall model. 

  • It is a step-by-step software test model for small projects with defined software necessities.
  • Follows a ‘V-shaped’ methodology categorized into coding, authentication, and validation. 
  • Every development stage goes hand-in-hand with testing, resulting in the early uncovering of bugs at every step. 

As soon as a specific phase of software development ends, the team begins testing a ready-made part of the product. This approach enables QAs to modify the product prematurely and save resources and time in the future.


  • Works perfectly for small projects when necessities are integrated & is much more cost-effective than the waterfall technique.
  • Every phase is well-tested and validated to discover errors early in the SDLC. 


  • No inherent capability to react to bugs during testing.
  • No pre-defined solution to eliminate the software flaw.

Use Cases

  • Commercial apps.
  • Defense projects & apps.
  • Government apps & software projects.
  • Medical devices & software apps.

Spiral Model

In this Quality Assurance technique, the spiral model, incorporates the waterfall and iterative development approaches. It is parallel to the incremental methodology with more concentration on threat analysis. The varied stages of the Spiral model comprise the planning stage, risk analysis, assessment, engineering stage, etc.


  • The time-box approach at every incremental phase reduces the overall threats in the software project. 
  • Has robust documentation support and functions well with bigger and more critical projects.


  • It is unsuitable and expensive for smaller projects. 
  • The method is difficult to use with legacy systems.

Use Cases

  • System modularization.
  • Enhancing app GUI (graphic user interface).
  • App prototypes (Design, Wireframe, & Clickable prototype).

Extreme Programming Model

In this Extreme Programming (XP) methodology, the programmer codes an easy code to obtain feedback on the user’s experience. This approach is based on an agile method that breaks the jobs into smaller sections. After every section is finished, the next section is operated on. This is used where the requirements of users are continuously evolving. 

Extreme Programming (XP) methodology is based on close collaboration between two teams. One team functions with the code, and another team instantly review it. Every phase of this testing technique can be considered finished once a code is excellently written and tested. This approach enables QAs to create superior-quality code as each line is scrutinized.



  • Customers with vague designs of software in mind could use excessive programming and scheduling.
  • Continuous testing, as well as integration of minor releases, makes sure top-quality software code.


  • There is a considerable time loss between the software development team and customers for brainstorming.
  • High volatile alterations could influence the productivity of apps.

Use Cases

  • Risk-related projects

Setting up Software Testing Methods

Software test methodologies should not be set up simply for testing product code. The broad picture must be considered, and the project’s primary objective must be satisfied with the test methodology.

  • Realistic Scheduling: Rational scheduling is the key to executing a successful testing methodology, and the agenda should meet the requirements of each team member.
  • Defined Deliverables: To keep all the team members on a similar page, well-defined deliverables ought to be offered. The deliverables must include direct content without any vagueness.
  • Testing Approach: Once scheduling and setting up are made and defined deliverables are accessible, the QA team should formulate the appropriate testing approach. Developer meetings and definite documents must indicate to the team the proper testing approach that can be utilized for the project.
  • Transparent Reporting: Clear reporting is very complex, but this step decides the effectiveness of the test approach used in the project.

Which Software Methodology to Choose?

The choice of any software methodology depends on manifold factors like the client requirements, the project nature, the project schedule, etc. In a few cases, development and testing go side by side, while others incorporate testing during later stages when the build is prepared.

  • As traditional software development methodologies like V-models, Waterfall, etc., are becoming outdated, many companies are adopting the agile software development model. 
  • Although the agile approach is renowned, it has several challenges that must be conquered. 
  • Some of the common challenges encountered in the agile method comprise slow feedback look, inadequate test coverage, deferring significant tests, etc.
