+## Testing
+
+The `ExpectThunk` helper, available as a CocoaPods subspec, allows for testing the order and contents of `dispatch` actions as well as the dependencies on `getState` contained within a thunk.
+
+```swift
+let expect = ExpectThunk(thunk)
+        .getsState(RequestState(loading: false))
+        // If the action is Equatable it will be asserted for equality with `dispatches`.
+        .dispatches(RequestStart())
+        .dispatches { action in
+            XCTAssert(action.something == expectedSomething)
