There are many methodologies and models to develop and test a software. The Digital Group implements the most efficient testing methodologies, in order to allow our clients to choose the most suitable models based on testing needs. They are as follows:

Agile methodology

Agile methodology testing model

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

  • Provide Continuous feedback
  • Communication
  • Keep it Simple
  • Have a Courage
  • Focus
  • Continuous advancement
  • Respond to change
  • Self-Organize
  • Deliver

Rapid Application Development (RAD)

Rapid Application Testing Model

The Digital Group's testing approach allows to create Zero Bug Defect software in fastest and efficient way. Generally, this is recommended in following factors:

  • Time Constraint of the Project
  • Unclear Requirements
  • Limited Budget to execute project
  • GUI factor

Traditional/Waterfall model

Waterfall testing model

We recommend Waterfall model for large projects where refined detail documentation is required. The sequence of phases are:

  • Gather and Analyze Requirements
  • Design
  • Implementation
  • Verification
  • Maintenance

Each of the above phases represent distinct stage of software development, and each stage generally finishes before the next stage begins.

Testing Process includes:

  • Inception
  • Elaboration
  • Construction
  • Transition

T/DG – Software Testing Philosophy


There may be some unavoidable risks during software testing like incomplete requirements, time allocations, delay in delivery, urgency from client, and defect leakage application due to size or complexity. To overcome mentioned challenges we do detail study of Risk Analysis where following activities are involved:

  • Conducting Risk Assessment review meeting with teams.
  • Profile for Risk coverage is created by mentioning the importance of each area.
  • Using maximum resources to work on High Risk areas like allocating more testers.
  • Creation of Risk assessment database for future maintenance and management review.
  • Identify and describe the risk magnitude indicators: High, Medium and Low.

Most organizations favor validation and ignore verification. Validation is actual testing in an executable mode and it mostly occurs once the software, or a "piece" of the software, is in a functional state. (Unit testing, regression testing, system testing, user acceptance testing, etc.)

Verification consists of those testing activities that occur during the 'building' phase of the software. (Walkthroughs, peer reviews, inspections, etc.)

Test Design and Execution are two core services of Testing. Test Design activities include review and analysis of testing goals and objectives, determination of Entry and Exit criteria, test conditions, creation of test cases, test procedures, test suites, identification and creation of necessary test data.

Test Execution means actual test activities which includes the execution of test cases or test scripts, manually or in an automated way, logging of test results, comparison of the expected and actual results, reporting the incidents and retesting the fixed bugs.
