Our Functional Testing Methodologies

At BIT Studios, we tailor our functional testing services to match the unique requirements of each project, using a variety of proven methodologies:

Waterfall Model

This traditional approach to software development involves a linear sequence of distinct phases, with functional testing conducted after development is complete.

  • Supports extensive automated testing at each development stage
  • Allows comprehensive test automation, ensuring stage completion before next progression

Agile Software Development

A flexible approach where we perform functional testing concurrently with development, with a focus on user story validation.

  • Enables refined, iterative test cases and enhanced regression testing
  • Promotes ongoing improvements in exploratory testing with functional testing tools


This model treats development and testing as two separate but parallel streams, with each level of development corresponding to a specific level of testing.

  • Allows for early detection and resolution of defects or inconsistencies
  • Reinforces the importance of functional testing services

Spiral Model

A risk-driven approach where functional testing is performed based on the risk patterns identified in each iterative loop.

  • Focuses on mitigating risks with the use of test data, leading to more robust software
  • Encourages frequent project revisions, ensuring errors are caught and corrected early

DevOps Model

An integrated approach where testing and development activities occur concurrently, with continuous functional testing at its core.

  • Enables faster deployment cycles, leading to improved time-to-market
  • Encourages DevOps collaboration, fostering a culture of shared responsibility
