Functional Testing


As the end-users’ expectations and demands continuously grow, the release of a new product without thorough testing phase can bring more risks now than ever before.
WinStream offers end-to-end functional testing services to ensure that your software behaves as it was intended, in compliance with all functional requirements and business needs.

Functional Testing Services We Provide :
  • Smoke testing
  • System testing
  • Unit testing / module testing
  • Regression / sanity testing
  • Integration testing
  • User acceptance testing

Our Approach to Functional Testing


We set off at the very beginning of the software development lifecycle.
The testing process covers 3 main stages:

Stage 1. Requirements analysis and clarification
Our specialists seamlessly integrate into your project team. The testing team works closely with BAs, developers and stakeholders to prevent unclear requirements in the specification.

Outcomes: the testing team dives into the project scope and specifics and drafts the test strategy.

Stage 2. Test planning and test design
  • Drafting test plan. The Test Lead drafts a detailed test plan that is reviewed by stakeholders and approved.
  • Test design. The testing team writes test cases/checklists according to the test plan and unite them into a test case document. Each requirement in the specification is transformed into a test case, so tests cover as much of specified behavior as possible.
  • Prep measures. WinStream testing team sets up a well-balanced strategy with an optimal mix of manual and automated testing.
Outcomes: the test plan, the test case document, the test environment and the test data are created and approved.

Stage 3. Stabilization
  • Test execution. Relying on the test case document and the test plan, our testing team tests the product using the prepared test data and test environment. For every build, the team runs testing according to the planned test level.
  • Defect reporting. Our testing team submits all the defects found to your preferred defect tracking system. Then we run exploratory testing powered by the team’s knowledge and experience to make sure no bug was missed.
  • Test reporting. Our testing team reports the results based on the agreed schedule. Test progress reports include:
      - Executed tests
      - Results
      - Defects found
  • Defect validation. When the defects are fixed, the testing team validates them to make sure they are gone.
  • Regression testing. When the defects are validated, the testing team runs regression testing to ensure that the adjacent areas of the application are fully functional. Usually a complete module or a functional block is retested.
Outcomes: the test summary report is prepared thus allowing you to get a full view of your product quality.
