 Reflective mocking libraries like [Foq](https://github.com/fsprojects/Foq) in my experience are a rich source of flaky tests.

 * You may supply an `isInternal : bool` argument to the attribute. By default, we make the resulting record type at most internal (never public), since this is intended only to be used in tests; but you can instead make it public with `[<GenerateMock false>]`.
 
+### Gotchas (GenerateCapturingMock)
+
+We use the same name for the record field as the implementing interface member:
+
+```fsharp
+type FooMock =
+    {
+        Field : string -> unit
+    }
+    interface IFoo with
+        member _.Field x = ...
+```
+
+If you have an object of type `FooMock` in scope, you'll get the *record field*, not the *interface member*.
+You need to cast it to `IFoo` before using it (or pass it into a function which takes an `IFoo`):
+
+```fsharp
+let thing = FooMock.Empty () // of type FooMock
+thing.Field "hello" // the wrong one! bypasses the IFoo implementation which captures calls
+
+// correct:
+let thing' = FooMock.Empty ()
+let thing = thing' :> IFoo
+thing.Field "hello" // the right one: this call does get recorded in the mock, because this is the interface member
+
+// also correct, but beware because it leaves the chance of the above footgun lying around for later:
+let thing = FooMock.Empty () // of type FooMock
+doTheThing thing // where doTheThing : IFoo -> unit
