# Floppy
Library, that dumps your test to files on first run.
On second run test's result are compared with dumps.
# Where is it needed?
For example, if you have many tests, which are checking function result, API for example. You can use Floppy
# Usage example
```elixir
test "Returns list of Items in the Cart" do
cart = Cart.find_by(email: "some.richman@microsoft.com)
items = CartItems.find_by(cart: cart)
Floppy.assert(items)
end
```
`Floppy.assert` on first run generates file with extension `.floppy`, but on second run `items` are compared with previous result.
If results are equal, test passed. Otherwise you have to change test or accept new result by command `FLOPPY_MODE=rewrite mix test path_to_failed_test.exs`
## Installation
