Updated product schema:

extend schema

    import: [

Test data:

const user = {
  averageProductsCreatedPerYear: if (totalProductsCreated) { 
    Math.round(totalProductsCreated / yearsOfEmployment)
  } else { 
    null

  totalProductsCreated: 1337,
  yearsOfEmployment: 10
 };

New test requires extend type User and doesn't allow for type User @extends for libraries that don't support the extend keyword

[kdawgwilk]

Also looks like the ordering of the @key directives also can cause the test to fail. e.g. My code first SDL generates

type Product @key(fields: "sku variation { id }") @key(fields: "sku package") @key(fields: "id")

but the test is looking for

type Product @key(fields: "id") @key(fields: "sku package") @key(fields: "sku variation { id }")

and so it fails even though these are syntactically equivalent

Thanks for catching those! I fixed the tests in #169 and #170 (you might need to rebase the PR).
