Our Functional Testing Approach

We begin testing at the earliest stage of the software development lifecycle. Our process includes three key phases:

  • Requirement Analysis & Clarification

    • Our testing experts collaborate closely with your business analysts, developers, and stakeholders to ensure a clear and shared understanding of requirements.
    • Outcome: A well-defined test strategy aligned with the project scope and objectives.
  • Test Planning and Design

    • Test Plan Creation: A comprehensive test plan is developed and approved by stakeholders, detailing the testing scope, strategy, schedule, and resources.
    • Test Case Development: Based on the plan, test cases and checklists are written to cover all functional requirements.
    • Preparation: We establish a balanced manual and automated testing approach and configure the necessary test environment and data.
    • Outcome: Approved test plan, test cases, test data, and testing environment are in place.
  • Stabilization & Execution

    • Test Execution: Functional tests are performed using the prepared cases and data for each build.
    • Defect Submission: All identified bugs are logged in your preferred defect tracking tool. Exploratory testing ensures no issue is overlooked.
    • Progress Reporting: Regular test reports highlight executed tests, results, and defects discovered.
    • Defect Revalidation: Fixed issues are retested to ensure resolution.
    • Regression Testing: Additional testing verifies that recent changes haven’t impacted existing functionality.
    • Outcome: A detailed summary report providing a clear picture of product quality and test coverage.
