Behind the scene specflow tests are just regular mstest unit tests. So you should be able to run them the same way using something like: To run a specific scenario: mstest /testcontainer:tests.dll /test:GivenMyScenarioWhenIDoSomeStuff To run a several specific scenario you can use the /test flag multiple times:

How to run SpecFlow tests across multiple test threads?
The SpecFlow binding registry (step definitions, hooks, etc.) and some other core services are shared across test threads. You have to use a test runner that supports in-process parallel execution (currently NUnit v3, xUnit v2, MSTest and SpecFlow+ Runner) You have to ensure that your code does not conflict on static state.
Can I use SpecFlow with NET Core?
Now that SpecFlow 3.0 has been released we can use SpecFlow with .NET Core. The CLI tool for .NET Core is dotnet and tests are run like this if you use MSTest (vstest): If the tests are in a specific project you can specify the project like this where TestProject is the name of the project.
Do I need a test runner to run SpecFlow scenarios?
In order to run the Specflow scenarios that we are going to create, we need a test runner. Specflow provides a runner out of the box called Specflow + Runner (which is a paid version and the free version introduces a delay). (Other runners are also available for NUnit and MsTest which we will see in the further articles in this series).

The Keywords – Given, When & Then
From the unit testing world, most of us are familiar with 3 A’s i.e. Arrange, Act and Assert. Now, Given, When and Then are the replacements for these in the BDD world.
The Feature File
The feature file is essentially a grouping of multiple scenarios for the application under development or test. It can also be simply thought of as different modules of the application by which the application can be logically separated.
What is Specflow?
Specflow is a tool supporting BDD practices in .NET framework. It’s an open source framework hosted on GitHub. It aids in using ATDD (Acceptance test driver development) for .NET Applications.
Specflow – Getting Started
In this section, we will explore installing specflow in the Visual Studio IDE and creating feature files for a simple String Utility Application.
Execution
As we have already added Specflow+ Runner in the above section, executing the Scenarios is pretty straightforward (since it’s an evaluation version of Specrun, it introduces a variable delay of 10-20s before the scenarios execute. , This delay is not present for registered variants and other flavors of Specrun runner like NUnit and MsTest).
Conclusion
Hope this article would have given you a basic understanding of what BDD is and what are the tools that support BDD for .NET where we covered Specflow.
What is SpecFlow hook?
SpecFlow comes with some predefined hooks that are executed after some events are fired during the tests’ execution. To make an analogy, think about TestInitialize and TestCleanup from MSTest framework.
What is hook in a scenario?
Definition. The hooks (event bindings) can be used to perform additional automation logic on specific events, such as before executing a scenario. Hooks are global but can be restricted to run only for features or scenarios with a particular tag (see below). The execution order of hooks for the same event is undefined.
