 # reflex-test-host
 
-This library contains functionality for writing unit tests for the "model" portion of your reflex-frp apps. Please see "test/Reflex/Test/SimpleHostSpec.hs" for basic usage example. You can find more usage examples in [this project](https://github.com/pdlla/reflex-potatoes?files=1) and [this one](https://github.com/pdlla/reflex-todo-undo-mvc-model).

 Note that `TriggerEvent` class constraint is not supported. It could be added with some effort but breaks the "pureness" of the test (at least from its inputs) so I don't suggest it. You can still test parts of your network that don't require `TriggerEvent`.
