1. BDD & Gherkin Fundamentals

Easy Very Common 1 minQ1 / 25

Q1.What is SpecFlow?

Asked byCognizantCapgeminiEYDeloitte
Why interviewers ask this

Interviewers open with "SpecFlow" to confirm you can define the concept in one crisp line before going deeper. In SpecFlow rounds this filters out candidates who only remember syntax and can't articulate the underlying idea to a non-expert teammate.

Detailed explanation

SpecFlow is the .NET port of Cucumber. It lets .NET developers write Gherkin feature files and bind them to C# step definitions. See our SpecFlow C# Automation Guide for a full walkthrough.

Tips to remember
  • Open with a one-sentence definition of SpecFlow, then a concrete SpecFlow example — never start with history or theory.
  • Keep the answer to 60–90 seconds; anything longer signals you can't summarise SpecFlow cleanly.
  • Speak in business language for Given-When-Then; SpecFlow panels flag developer-speak.

Q4.What's the difference between Given, When, and Then?

Asked byCapgeminiEYDeloitteMicrosoft
Why interviewers ask this

Comparison questions like this test whether you understand Given, When, vs Then at a design level — not just that both exist, but when to pick one over the other. Panels use it to see if you can defend a trade-off with a real project example.

Detailed explanation
  • Given — state before the action ("I am logged in").
  • When — the action ("I click submit").
  • Then — the expected outcome ("I should see…").
Tips to remember
  • Structure the answer as a small table in your head: dimension, option A, option B — and close with "I'd pick X when Y".
  • Group the Given, When, vs Then points into 2–3 buckets so you can recall them under pressure without missing one.
  • Speak in business language for Given-When-Then; SpecFlow panels flag developer-speak.

Q21.Can SpecFlow run scenarios in parallel?

Asked byMicrosoftPWCTCSAccenture
Why interviewers ask this

Scenario questions on Can SpecFlow run scenarios in parallel check whether you can turn SpecFlow knowledge into action inside a real team. Panels want a diagnosis, a first step, a validation plan, and a rollback — in that order.
