RSpec::WithParams
Simple parameterized testing (a.k.a table tests) with RSpec.
RSpec.describe "my complex business logic" do
extend RSpec::WithParams::DSL
with_params(
[:today, :schedule, :expected_date],
["2019-06-05", "weekly", "2019-06-13"],
["2019-06-05", "bi-weekly", "2019-06-20"],
["2019-06-05", "monthly", "2019-07-13"],
) do
it "determines the next appointment date" do
result = NextAppointmentCalculator.new.process(today, schedule)
expect(result).to eq expected_date
end
end
endOutput (with --format documentation):
my complex business logic
given today -> "2019-06-05", schedule -> "weekly", expected_date -> "2019-06-13"
determines the next appointment date
given today -> "2019-06-05", schedule -> "monthly", expected_date -> "2019-06-20"
determines the next appointment date
given today -> "2019-06-05", schedule -> "bi-weekly", expected_date -> "2019-06-20"
