This scenario is very common, and inevitably will make the test harder to read, increasing the potential for misunderstanding the intent, which in turn will increase the likelihood of mistakes being made when the test or related code is changed. Before we see how to improve the test, we will learn about the let helper:
describe AddressValidator do
let(:address) { {street: "123 Any Street", city: "Anytown"} }
it "valid? returns false for incomplete address" do
expect(AddressValidator.valid?(address)).to eq(false)
end
it "missing_parts returns an array of missing required parts" do
expect(
AddressValidator.missing_parts(address)
).to eq([:region, :postal_code, :country])
end
context "invalid characters in value" do
let(:address){ {street: "123 Any Street", city: "Any$town%"} }
it "invalid_parts returns keys with invalid values" do
expect(
AddressValidator.invalid_parts(address)
).to eq([:city])
