Software TestingMethodologies

The Need for Software Testing Methodology Services

Software testing methodologies consist of steps and techniques that define the phases of the software testing process. Different types of methodologies are used in software testing and quality analysis. However, irrespective of the software testing methodology you choose, the goal is to make the software free of bugs, errors and defects.

Here are some of the common challenges that organizations face when it comes to software testing & quality assurance services.
  • Effective analysis of testing requirements.
  • Conducting testing at desired intervals during the software development life cycle.
  • Keeping a check on escalating costs due to the identification and removal of bugs at later stages of the software life cycle.
  • Regulating the time to market.
  • Preventing quality issues due to insufficient provision for quality testing.
  • Meeting regulatory standards.
  • Successfully covering the entire set of test objectives.

Helping you Discover the most Efficient Testing Methodology for your Testing Needs

We offer software testing as a service and implement the most efficient testing methodologies, in order to allow our clients to choose the most suitable models based on testing needs. Given below are 3 software testing models:

A form of incremental model, agile software testing model involves development of software in incremental, rapid cycles. So, you have small incremental releases of the software, each one building on previous functionalities. The fact that each release is thoroughly tested ensures delivery of high quality software every time. Agile methodology is based on the concept that the needs of the end users are ever-changing, and hence it allows for a lot of freedom for change. It facilitates the easy implementation of new changes, without losing on several days of developers’ work. This makes it a very cost-effective approach to software testing.

Agile uses iterative approach. While using this approach, software development has to be broken down into many short cycles that help to minimize risks. Agile methodology is based on the following principles:

  • Highest levels of customer satisfaction through continuous delivery of valuable software.
  • Accommodate for changes even late into the software development stages.
  • Priority to the motivation levels of the people working on a project.
  • Consider working software as the primary measure of progress
  • Promote sustainable development
  • Keep it simple.
  • Respond to change.

Another form of incremental model, Rapid Application Development (RAD) model is all about an adaptive approach that emphasizes more on adapting the software to cater to the user requirements. In rapid application development for enterprise, a prototype is created by assembling the different components of the software product that have been developed in parallel. The prototype is then used to gather feedback from the customer.

The RAD model is recommended when the product is required to be delivered within a short period of 2-3 months and there is a high availability of skilled resources.

Phases of the RAD Model:

  • Business Modelling
  • Data Modelling
  • Process Modelling
  • Application Generation
  • Testing and Turnover

Also known as a linear-sequential life cycle model, the traditional waterfall development approach is the first process model and is one of the least flexible models, offering very little scope for iteration. This model is highly simple and its basic principle is the completion of each phase before the next phase begins. In the waterfall model, testing can start only when the development is complete and hence, there is no overlapping of the phases.

The Waterfall Model is recommended for short projects when ample resources are available and the project requirements are clear and there is no ambiguity. However, the cost of fixing bugs and defects is very high in case of this model.

Given below are the phases of the Waterfall Model:

  • Requirement Gathering
  • System Design
  • Implementation
  • Testing
  • Deployment
  • Maintenance

We Ensure High Performance & Faster Time to Market for Your Software Applications

There are several challenges that come up during the software testing process, such as incomplete requirements, insufficient time allocations, delay in delivery, urgency from client, and defect leakage in applications due to size or complexity, among others. T/DG believes in a detailed study of Risk Analysis to overcome these challenges, which involves the following activities:

  • Conducting Risk Assessment review meeting with teams.
  • Creating profile for Risk coverage by mentioning the importance of each area.
  • Using maximum resources to work on High Risk areas.
  • Creating a Risk assessment database for future maintenance and management review.
  • Identifying and describing the risk magnitude indicators as High, Medium and Low.
