Our approach to functional testing

We set off at the very beginning of the software development lifecycle.  Testing process runs as follows: 

Testing process

Stage 1. Requirement analysis and clarification

Our specialists seamlessly integrate into your project team. The testing team work closely with BAs, developers and stakeholders to prevent unclear requirements in the specification.

Outcomes: The testing team dive into the Project scope and specifics and draft 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 write 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 set 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 test plan, our testing team test the product using the prepared test data and test environment. For every build, the team run testing according to the planned test level.
  • Defect reporting. Our testing teams submit 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 report 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 validate them to make sure they are gone.
  • Regression testing. When the defects are validated, the testing team run regression testing to ensure that the adjacent areas of the application are fully functionalUsually a complete module or a functional block is retested.

Outcomes:Outcomes of testing process

Reporting and bug tracking specifics

  • Once we have completed each test suite, we deliver a test report with all the quality issues we discovered. Each bug status is documented and is tracked throughout the life cycle.
  • Our team use 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 test automation.

...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.
