testCreateDeps - API reference

API reference › @evolu/common › Test › testCreateDeps

function testCreateDeps(options?: { seed?: string }): TestDeps;

Defined in: packages/common/src/Test.ts:77

Creates deterministic TestDeps.

Each call creates fresh instances, so tests don't share state.

Includes these deps:

console: TestConsole
random: Random
randomLib: seeded random package instance
randomBytes: RandomBytes
time: TestTime

Use this for synchronous code that accepts deps directly. For tests that run Tasks, use testCreateRun.

Example

test("Callbacks with no argument", () => {
  const deps = testCreateDeps();
  const callbacks = createCallbacks(deps);

  let called = false;
  const id = callbacks.register(() => {
    called = true;
  });

  callbacks.execute(id);
  expect(called).toBe(true);
});
