Usage Example
The example below describes a feature containing a test scenario, borrowed from the Gherkin docs. The module goes inside the /test folder, just like any other ExUnit test.
defmodule ExunitGwtExample do
use ExUnit.Case
import ExUnitGWT
feature "Serve coffee: in order to earn money customers should be able to buy coffee at all times" do
scenario "Buy last coffee" do
given? "there are 1 coffees left in the machine" do
coffees_left = 1
coffee_price = 1
end
and? "I have deposited 1 dollar" do
dollars_deposited = 1
end
when? "I press the coffee button" do
coffees_received = coffee_price * dollars_deposited
coffees_left = coffees_left - coffees_received
end
then? "I should be served a coffee" do
assert coffees_received == 1
end
and? "There should be no coffees left in the machine" do
assert coffees_left == 0
end
end
end
end
