SpecFlow Interview Questions
Interviewing for a .NET role that uses SpecFlow (or its successor Reqnroll)? Practice with an AI that asks about Gherkin bindings, step definitions, hooks, scenario context, and how BDD fits a .NET test stack.

What do interviewers ask about SpecFlow?
SpecFlow interviews cover how Gherkin feature files bind to C# step definitions, the regex/expression matching that links steps to methods, and hooks (BeforeScenario, AfterScenario, BeforeFeature) for setup and teardown. Expect questions on passing state with ScenarioContext and dependency injection, data tables and step argument transformations, Scenario Outline with examples, and tags for filtering. You will also be asked how SpecFlow integrates with NUnit/xUnit/MSTest and Selenium, runs in CI, and, increasingly, about the move to Reqnroll after SpecFlow's end-of-life announcement.
What do SpecFlow interviewers ask at junior, mid and senior level?
The same tool, three different interviews. Find your row before you prepare.
| Level | What interviewers probe | Typical question |
|---|---|---|
| Junior | What interviewers probeGherkin in .NET, step bindings, hooks, and how a feature file connects to C# code. | Typical questionHow does SpecFlow match a Gherkin step to a C# method? |
| Mid-level | What interviewers probeContext injection for sharing state, scenario outlines with tables, tags, and living documentation. | Typical questionHow would you share state between steps without static variables? |
| Senior | What interviewers probeSpecFlow versus Reqnroll after the licence change, BDD adoption across teams, and step library governance. | Typical questionHow would you plan a migration from SpecFlow to Reqnroll for a suite of 300 features? |
Which SpecFlow topics come up most?
Key areas interviewers evaluate when asking about specflow.
Gherkin & Bindings
Feature files binding to C# steps, expression/regex matching, and keeping steps reusable.
Step Definitions
Writing Given/When/Then methods, parameters, and step argument transformations.
Hooks & Lifecycle
BeforeScenario/AfterScenario/BeforeFeature hooks for setup, teardown, and ordering.
Context & DI
Sharing state with ScenarioContext, context injection, and avoiding leaking state between scenarios.
Data Tables & Tags
Data tables, Scenario Outline examples, and tag-based filtering of scenarios.
Runners & CI
Integration with NUnit/xUnit/MSTest and Selenium, living documentation, and CI execution.

Frequently Asked Questions
What is SpecFlow?
SpecFlow is a BDD framework for .NET that binds Gherkin feature files to C# step definitions, the .NET equivalent of Cucumber. It lets teams write executable specifications in business-readable Given/When/Then language.
What is Reqnroll and why does it matter?
SpecFlow reached end of life, and Reqnroll is the open-source fork that continues it. Interviewers may ask whether you know about the transition, since many .NET teams are migrating from SpecFlow to Reqnroll.
How is SpecFlow different from Cucumber?
They are conceptually the same BDD approach with Gherkin. SpecFlow targets .NET and C# bindings and integrates with NUnit/xUnit/MSTest, while Cucumber targets the JVM, Ruby, and JavaScript ecosystems.
Can I practice SpecFlow questions on AssertHired?
Yes. The AI interviewer asks SpecFlow bindings, hooks, and BDD questions with follow-ups and scores you across four dimensions.
