    It just just enough abstraction over the basics of converting your HTTP calls to GraphQL queries and mutations, but ALL of the parsing of responses is on you. I’m well versed in parsing JSON in Elm. I’m also familiar with the compiler errors as well as runtime errors you get with JSON that doesn’t match up to what you designed. At some point I’ll probably have to move beyond the unit tests and add contact tests, maybe via Pact.js.

    > I also wasn't aware that "unit" referred to an isolated test, not to the SUT.

    I'm with you. That claim is unsubstantiated. It seems to trace to the belief that the first unit tests were XUnit family, thus were SUnit for Scheme. But Kent Beck made it pretty clear that SUnit "units" were classes.

    https://web.archive.org/web/20150315073817/http://www.xprogr...

    There were unit tests before that. SUnit took its name from common parlance, not vice versa. It was a strange naming convention, given that the unit testing framework could be used to test anything and not just units. Much like the slightly older Test Anything Protocol (TAP) could.

    > [on unit tests] This does lead to a lot of work maintaining them whenever the implementation changes, but this is a necessary chore because of the value they provide.

    I disagree. Unit tests can still be behavioral. Then they change whenever the behavior changes. They should still work with a mere implementation change.

    > This is why I still think that the traditional test pyramid is the best model to follow.

    I'll disagree a little with that, too. I think a newer test pyramid that uses contract testing to verify integrations is better. The notion of contract tests is much newer than the pyramids and, properly applied, can speed up feedback by orders of magnitude while also cutting debugging time and maintenance by orders of magnitude.

    On that front, I love what Pact is doing and would like to see more competition in the area. Hottest thing in testing since Cypress/Playwright . . .

  • A response to James Shore's Nullable pattern
    1 project | news.ycombinator.com | 16 Jan 2023
    I'd never heard anyone call those "integrity tests" before. I think "contract test" is more common.

    Assuming I understood you, that is.

    I've been telling everyone to look at Pact to make contract testing easier to organize and maintain and to make it easier to trigger in the other tests in CI when an interface's behavior changes. They haven't offered me a commission yet. ;-)

    We use pact and since introducing it we have significantly increased velocity and reduced test cycles as it catches things very early. For system tests we hand write them using whatever test frameworks the team is used to.

    When you wish to focus on the contract ( which kind of field is required, ...), you shoud use contract testing frameworks. As you seem to leverage a microservices, a consumer driven contract testing approach with a framework like Pact.js is recommended.
