In IT industry, domain knowledge is considered as incredible value .Undoubtedly domain knowledge is a critical success factor for testers. Testing skill and technology/tool knowledge is our core capability and having domain awareness is like “icing on the cake” (something good is added to another good thing!). We seamlessly integrate domain and functional knowledge into our QA life cycle.
We strongly believe that quality assurance is directly related to business assurance and that mandatorily needs a strong understanding of the client domain and the ecosystem of the application under test. We train our testers in domain and for certain engagements include a subject matter specialist from the domain as part of the QA team.
Among software testing techniques, Domain and functional knowledge is probably most widely described and most widely practiced to shepherd domain expertise.
