Add value to the customer experience with manual software testing services

In our manual functional testing, we follow a 4 step plan that includes identifying test requirements, creating test design and test cases, logging defects, and keeping all the stakeholders apprised of the release health throughout. In all the stages of functional testing services, the user's perspective is at the heart of each test plan.

  • We start manual functional testing with a laser focus on the end customer’s needs and expectations
  • For software functional testing, we create a test strategy for the application outlining the ‘perceived quality’
  • Our manual testing services approach is based on the analysis of the impact of delta releases
  • Frequent interactions between product owners and the development team for improved software decisions

Steps of functional testing services to match your vision with the user’s expectations



Identifying testing requirements

We analyse the user journey, stakeholder needs, and the existing knowledge base to create the test plan for manual functional testing



Creating test designs and test cases

We identify test scenarios based on the variety of ways the system would be used by the user at the most granular level and design test cases for every unique scenario.



Identify and prioritise test cases

For manual software testing, we execute tests in 2 cycles, prioritise tests and make the requisite documentation in the requirement traceability matrix.



Identifying & resolving defects

We categorise defects based on their priority and severity and give a detailed walkthrough to our clients on release health. Based on defect resolution, adjustments are made in the RTM.
