specflow gives error after adding more string parameters

问题

Spec flow was working fine. I added some more string parameters in one of the Given statement and suddenly I start getting this error

Class Initialization method AutomatedRediTests.RediFeature.FeatureSetup threw exception. BoDi.ObjectContainerException: BoDi.ObjectContainerException: Primitive types or structs cannot be resolved: System.String.

How do I go about resolving this error? It asks to resolve System.String

EDIT:

looks like in specflow bindings I have a line someMachine abc = SomeControl.BeforeTestRun(); and I needed it to change so it passes a string like someMachine abc = SomeControl.BeforeTestRun("someString"); . When I pass this string , I get this error. No matter if I write the line inside a step definition method or just inside the class.

Is there a way to achieve this?

回答1:

You get this error, if you have a string parameter in the constructor of a class that you get via context injection.
