Quality Assurance Testing Techniques

Waterfall Model

Software development and testing is approached using the standard, linear Waterfall Model. It is divided into phases in a sequential order, each requiring the completion of the preceding stage.


  • Meticulous and organized.
  • Clear requirements before the start of testing.
  • The requirements, design, implementation, testing, and deployment phases proceed linearly.


  • Explicit documentation at every stage.
  • Simple to comprehend and use.
  • Fit for projects with precise specifications.


  • Projects whose needs are constant and predictable.
  • Little to medium-sized projects in which adaptability is not the main issue.
  1. Agile Testing: 

Agile is a collective, iterative process that orders flexibility and customer input. Agile testing is a constant procedure at every stage of the development lifecycle.


  • Iterative sprints or cycles.
  • A focus on client cooperation.
  • Fast adjustment to shifting needs.
  • Testing at every stage of development.


  • Quick adaptability to changes.
  • Better inter-team communication.
  • Increased customer satisfaction with frequent and incremental updates.


  • Initiatives with changing or ambiguous specifications.
  • Sizable undertakings can be divided into more manageable, minor phases.
  1. DevOps Testing: 

DevOps is a method that unifies operations and development, highlighting teamwork and communication. Testing is easily integrated across the whole development lifecycle.


  • Cooperation amongst teams working on development, testing, and operations.
  • Practices for continuous delivery and integration (CI/CD).
  • Process automation for testing.


  • More dependable and quicker discharges.
  • Enhanced teamwork and communication.
  • The automated use of resources to maximize efficiency.


  • Tasks requiring constant and quick delivery.
  • Situations where cooperation between operations and development is essential.
  1. V-Model (Verification and Validation):


The V-Model emphasizes the relationship between each development stage and its matching testing phase. It is an extension of the Waterfall Model.


A testing phase corresponds to every step of development.

  • Verification is the main focus of early testing phases, and validation is the main focus of later stages.
  • Traceability between test cases and requirements.


  • A clear relationship between requirements and test cases.
  • Early defect identification by use of validation.
  • Strict testing at every turn.


  • Projects where early verification is essential;
  • Projects with clearly stated requirements.
  1. Exploratory Testing:

Testers create and carry out test cases in this unscripted method while concurrently learning about the application.


  • Examiners investigate the application without pre-established test scenarios.
  • At the moment, testers decide based on their observations.
  • During testing, I provide real-time feedback and modifications.


  • Effective in identifying intricate and unanticipated flaws.
  • Promotes innovation and adaptability in testing;
  • Emulates real-world user interactions.


  • Projects with ambiguous or changing criteria; • Projects that call for adaptability and inventiveness in testing.
