## Quick Summary:

Software testing methodologies play an essential part in the development cycle of software. Software testing methodologies are the strategies used to ensure that the software is running perfectly or not. This article focuses on mainly five methodologies that are widely used for software testing across the world.

The chances of doing or having an error are negligible in this modern world. So, in the whole software development cycle **software testing methodologies** plays an important role. This methodology gives the organization a direction about how to test software.

**Let's make this an example to indicate.**

In January 2016, the famous HSBC bank faced a big outage of IT. Because of this situation, millions of customers could not access their accounts for two days. The COO of the HSBC bank stated that it was because of a 'unique technological problem' within the internal system of the bank. 

So, with the help of this incident, we can understand that software development is a very delicate process and utmost care should be taken while developing as well as testing it with the help of different methodologies.

With the help of this article, I will explain to you the software testing methodologies along with their widely used types.

## Firstly, What is Software Testing Methodologies?

Software testing methodologies are the strategy of developing and testing software simultaneously per the client's requirements. It involves testing the product and its functionalities in accordance with its specifications.

## Software Testing Methodologies:

The following are the top five widely used software testing methodologies:

###(1) Waterfall Methodology: 

A waterfall methodology is an approach in which the focus is on the process of development and it follows the vertical path. In this approach, after the completion of one phase, the next phase of the development process would begin. 

This approach is divided into five phases and they are as follows:

- Requirement
- Design
- Implementation
- Verification
- Maintenance

###(2)Agile Methodology:

The agile methodology is a software testing methodology in which the whole project is divided into small phases and development is made in a fast incremental cycle. In agile methodology instead of testing the entire system at the end, every iteration is released after its successful testing. 

The following are the agile methodologies used for agile development:

- Scrum
- XP
- Crystal
- FDD
- DSDM
- Lean Software Development

###(3)Iterative Development Methodology:

In this methodology, a large project is broken down into small components and each component is tested thoroughly. Per iteration is founded on the outcomes of prior iterations because the model is data-driven.

The following are the stages of iterative development methodology:

- Planning Phase
- Requirements 
- Analysis & Design Phase
- Implementation Phase
- Testing
- Evaluation

###(4)Verification & Validation Methodology:

The Verification and Validation Methodology is considered an extension of the waterfall model and it is mainly used for small projects with specific and determined software requirements. It is a classified into Verification, coding, and validation. In this model, the coding is considered as the base of the model and each phase of the development goes collectively with testing and because of this, the error can be detected as early as possible. 

Verification and validation is the independent methodology used to find whether the product, service, system, or component fulfills its specified requirement and whether the predefined purpose is satisfied.

###(5)Rapid Action Development Methodology:

Rapid Application Development is a _Software testing Methodologies_ that focuses on developing applications with the help of continuous iterations and feedback. The RAD methodology consists of five phases. The first phase is business modeling which will identify the requirements of the business and this phase also determines the flow of the information toward other channels of the organization. 

After determining the information flow, the data modelling stage will examine all relevant data in accordance with the business model. The third phase is process modeling in which the data objects establish the flow of information in the business. In this phase, modification is done as per the client's feedback. The fourth stage is known as prototyping, and it is where the models are coded using automated tools. The final step is the testing and turnover phase, during which each prototype is tested individually and risks and errors in the overall software are reduced.

So, the above all were the five widely used phases of the software testing methodologies. 

## Conclusion:

In software development testing plays a key role in its life cycle. With the help of testing the performance of the software can be enhanced, security can be improved and quality assurance can be provided. It guides the software in such a way that it is developed as per the requirements of the client or not. So, software testing methodologies play an essential role in developing the software.
