Does @xstate/test support xstate V5?

[iliasbhal]

👋 Hey Community!

I was starting a fresh project, so naturally I'm using xstate and nonetheless the V5.
I didn't have luck generating tests using @xstate/test.
I started by recreating the example in the docs but it didn't work 🥲

 const toggleMachine = x.createMachine({
    id: "toggle",
    initial: "inactive",
    states: {
      inactive: {
        on: {
          TOGGLE: "active",
        },
        meta: {
          test: async () => {
            console.log("TEST INACTIVE");
          },
        },
      },
      active: {
        on: {
          TOGGLE: "inactive",
        },
        meta: {
          test: async () => {
            console.log("TEST ACTIVE");
          },
        },
      },
    },
  });

  const toggleModel = xt.createModel<{}>(toggleMachine).withEvents({
    TOGGLE: {
      exec: async () => {
        // await page.click('input');
      },
    },
  });

  const testPlans = toggleModel.getShortestPathPlans();
  testPlans.forEach((plan) => {
    describe(plan.description, () => {
      plan.paths.forEach((path) => {
        it(path.description, async () => {
          await path.test({});
        });
      });
    });
  });

Hey! Have you tried @xstate/test@beta?

[davidkpiano]

Sorry, there was a typo. Try the same link again?

Hi David,

The link works! Thanks. Do you and the stately team have a timeline for releasing a stable version for the @xstate/test that is compatible with v5 of xstate? I too am a new comer to the xstate library but have been really enjoying modeling my application state using fsm.

I will try to get it to the finish line next week 🤞

Looking at the changelog I belive this is still in beta? We are also using and loving xstate5 and would love to test with a stable version. Thanks!

@cbishop-fv The plan is to release a major version of @xstate/graph, which includes everything from @xstate/test. It's being consolidated into one package since they are closely related, and I want to emphasize that @xstate/test is not for testing XState machines, it's for using XState machines to test anything.
