createTestModel

Callable

• createTestModel<TMachine>(machine: TMachine, options?: Partial<TestModelOptions<SnapshotFrom<TMachine>, ResolveEventType<TMachine>>>): TestModel<SnapshotFrom<TMachine>, EventFrom<TMachine>, unknown>

---

• Creates a test model that represents an abstract model of a system under test (SUT).

  The test model is used to generate test paths, which are used to verify that states in the machine are reachable in the SUT.

  @example

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

  Type parameters

  • TMachine: AnyStateMachine

  Parameters

  • machine: TMachine

    The state machine used to represent the abstract model.

  • optionaloptions: Partial<TestModelOptions<SnapshotFrom<TMachine>, ResolveEventType<TMachine>>>

    Options for the created test model:

    • events: an object mapping string event types (e.g., SUBMIT) to an event test config (e.g., {exec: () => {...}, cases: [...]})

  Returns TestModel<SnapshotFrom<TMachine>, EventFrom<TMachine>, unknown>
