Since now I finished migrating to Apollo 3 and started using data builders, I am running often into this issue where I forget specifying my custom FakeResolver, and the tests fail because the default FakeResolver doesn't know how to instantiate our custom scalars. Have you considered adding a mechanism that would allow specifying a global custom FakeResolver, so we don't have to pass the same custom one over and over again for each builder? 😄

Interesting question!

[mbonnin]

The more I think about this, the more I think there's something to be done around codegen for customscalars

[mbonnin]

For an example, having to pass CustomScalarAdapters during ApolloClient is a bit cumbersome

[mbonnin]

not to mention passing it around in ApolloStore (see this issue)

[mbonnin]

We could theorically make everything at compile time I guess, just change the entry point (ApolloClient would become abstract and we'd codegen MyServiceApolloClient preconfigured with the "good" custom scalars)

[mbonnin]

But short term I guess we could just make another codegen compiler option to replace DefaultFakeResolver with another symbol

[mbonnin]

In all cases, do you mind opening an issue so that we can keep track of this?

Sure thing, will do tomorrow! Thanks! 🙂
