How do you handle incomplete or ambiguous requirements during functional testing?<\/strong><\/li>\n<\/ol>\n\n\n\n\u201cI clarify requirements by discussing with business analysts, developers, and product owners. If details are still unclear, I create assumption-based test cases and seek validation from stakeholders. I also use exploratory testing to uncover unexpected issues.\u201d<\/em><\/p>\n\n\n\n\n- What are positive and negative test cases? Can you provide examples?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n- Positive test cases<\/strong> check if the system works as expected. Example: Entering valid login credentials should grant access.<\/li>\n\n\n\n
- Negative test cases<\/strong> check how the system handles invalid inputs. Example: Entering incorrect login details should show an error message.<\/li>\n<\/ul>\n\n\n\n
\n- How do you test an application when you have limited time?<\/strong><\/li>\n<\/ol>\n\n\n\n
\u201cI prioritize critical functionalities and high-risk areas first. I use risk-based testing, exploratory testing, and automation where possible. Smoke testing helps confirm basic stability before deeper testing.\u201d<\/em><\/p>\n\n\n\n\n- What challenges have you faced in functional testing, and how did you resolve them?<\/strong><\/li>\n<\/ol>\n\n\n\n
\u201cOne challenge I faced was testing a feature with vague requirements. I addressed it by collaborating with stakeholders, documenting assumptions, and refining test cases as feedback came in.\u201d<\/em><\/p>\n\n\n\n<\/span>Functional Testing Interview Questions for 3 Years\u2019 Experience<\/span><\/h3>\n\n\n\n\n- How has your approach to functional testing evolved over the last three years?<\/li>\n\n\n\n

<\/span>Manual Functional Testing Interview Questions<\/span><\/h2>\n\n\n\n\n- What are boundary value analysis and equivalence partitioning?<\/strong><\/li>\n<\/ol>\n\n\n\n
Boundary Value Analysis (BVA) tests edge cases by selecting values at the lower and upper limits. For example, if an input field accepts values from 1 to 100, test cases would include 0, 1, 100, and 101.
Equivalence Partitioning (EP) divides input data into valid and invalid groups, assuming all values within a partition behave similarly. For the same 1\u2013100 range, test cases might use 10, 50, and 90 for valid inputs and -5, 0, and 150 for invalid ones.<\/p>\n\n\n\n
\n- What factors determine the priority and severity of defects in manual testing?<\/strong><\/li>\n<\/ol>\n\n\n\n
\n- Severity<\/strong> depends on how much the defect impacts functionality. A system crash is high severity, while a minor UI misalignment is low.<\/li>\n\n\n\n
- Priority<\/strong> is based on how urgently the defect needs fixing. A bug blocking a major feature in production is high priority, while a spelling error in a rarely used screen is low.<\/li>\n<\/ul>\n\n\n\n
