Specflow.StepInterceptor
Allows a collection of Actions to be invoked before or after a step type seamlessly.
E.g. Invoke .build() on a builder just before the first When step is called. Removing the need for a filler step to build the object.
Usage
- Build repo
- Add Specflow.StepInterceptor reference to your specs project
- Add library reference to your app.config
