Our Approach to Functional Testing

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

Requirement analysis and clarification

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.

Test planning and test design

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. ScienceSoft’s 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.

Reporting and Bug Tracking Specifics

We ensure full transparency and control over the testing process delivering a comprehensive set of test documentation:

  • Checklists and test plan
  • Test cases
  • Test results report
  • Quality KPI describing the overall project quality and testing efficiency

Our team uses tried-and-true bug tracking and task management systems, such as:

  • Atlassian Jira
  • LogiGear TrackGear
  • HP Quality Center
  • Bugzilla
  • Rational ClearQuest

Always open to dialogue, we are ready to use bug tracking tools you prefer.

Actions Speak Louder

With our functional testing services, we have helped industry leaders, including IBM and Tieto, to get a top-quality product within time and budget in the following way:

Avoiding expensive rework (500 – 1000 man-hours) via detecting system bottlenecks at early project stages.

Reducing time between releases and developers’ idle time during testing by 15% - 20%.

Saving up to 700 man-hours per iteration thanks to automated testing.

...But Words Also Matter


We first turned to ScienceSoft in 2011 for testing our core application with many ERP and mobile elements. We have worked with the team in very close cooperation ever since and value professional as well as flexible attitude towards testing. We look forward to expanding our cooperation as our customer base also grows, which is a direct result of higher quality standards that ScienceSoft helps us to achieve.
