Testing Our Query
GraphiQL is a great tool to explore our API and when we’d like to manually run a query, but it’s not a replacement for a test suite. We’ll use ExUnit to add tests for our Absinthe schema to make sure our queries work now and later on to prevent regressions. Our future selves will appreciate the forethought.
ExUnit is bundled with Elixir, so no dependencies are required. Since our PlateSlate application is using Phoenix, ExUnit has already been set up with a preconfigured test harness that we can use.
Because we know our users are going to use the API by hitting /api, we can treat our API just as we would a Phoenix controller, using the PlateSlate.ConnCase helper module that Phoenix generously generated for us:
