Wrapping a spec with a behavior

One very common use for a behavior is to wrap a spec in a transaction scope. This way, any changes the spec makes can be rolled back once the spec executes. First, let's register the behavior: [block:code] { "codes": [ { "code": "WhenTesting<INeedATransaction>().EnrichWith<TransactionScopeWrapperBehavior>();\n", "language": "csharp" } ] } [/block] Now we just need the behavior and the marker interface: [block:code] { "codes": [ { "code": " public interface INeedATransaction : ISpecs\n {\n }\n\n public class TransactionScopeWrapperBehavior : Behavior<INeedATransaction>\n {\n private TransactionScope _scope;\n\n public override void SpecInit(INeedATransaction instance)\n {\n _scope = new TransactionScope();\n }\n\n public override void AfterSpec(INeedATransaction instance)\n {\n _scope.Dispose();\n }\n }", "language": "csharp" } ] } [/block] Any spec can now automatically wrap itself in a transaction scope just by implementing the INeedATransaction interface.
