Testing `Option` Types with Custom Assertions

import * as Option from "effect/Option";
import { assert } from "@effect/vitest";

export const assertSome = <T>(
  option: Option.Option<T>,
  message: string = "Expected Some, got None"
): T => {
  return Option.match(option, {
    onNone: () => assert.fail(message),
    onSome: (value) => value,
  });
};

export const assertNone = <T>(
  option: Option.Option<T>,
  message: string = "Expected None, got Some"
): void => {
  Option.match(option, {
    onNone: () => {},
    onSome: () => assert.fail(message),
  });
};

  it.effect("setToken stores provided value", () =>
    Effect.gen(function* () {
      const store = yield* TokenStore;
      yield* store.setToken("abc");

      const token = yield* store.getToken;
      const value = assertSome(token);

      expect(value).toBe("abc");
    })
  );
