Do you have a repo I can take a look at? I've working tests in a few public repos like https://github.com/Cherry/ShareX-R2-Cloudflare-Workers, https://github.com/Cherry/placeholders.dev, https://github.com/nodecraft/crafthead etc. if they're helpful.

thanks, i think i got closer and found out that it's related to the actual test. i was using UnstableWorker which seems to be deprecated. i'll gladly take a look at your repos, thank you!

Ahh yes

UnstableWorker

UnstableWorker

UnstableWorker

UnstableWorker was what was used before the direct vitest integration - there's no need to use that anymore

do you have any example using DOs?

E

else•12/27/24, 10:38 PM

yea the UnstableDevWorker stuff is linked here, so maybe it is actually still required for testing DOs? https://developers.cloudflare.com/durable-objects/examples/testing-with-durable-objects/

it's not - that's old

Check out https://github.com/cloudflare/workers-sdk/tree/main/fixtures/vitest-pool-workers-examples/durable-objects

runInDurableObject

runInDurableObject

runInDurableObject

runInDurableObject is the key part though

right, i was just checking this one: https://github.com/cloudflare/workers-sdk/blob/main/fixtures/vitest-pool-workers-examples/durable-objects/test/direct-access.test.ts

yet,

env.MYDO.get()

env.MYDO.get()

env.MYDO.get()

env.MYDO.get() returns undefined

even if you use that exact fixture's code? If you can create a minimal repro and open an issue at https://github.com/cloudflare/workers-sdk/issues, that would be ideal if there's a bug here

well i tried to minimize it to this:

import { env, runInDurableObject, SELF } from 'cloudflare:test';
import { expect, suite, test } from 'vitest';
import { CheckerDO } from '../src/checker';

suite('first test', () => {
    test('generate a CheckerDO', async () => {
        const id = env.CHECK.idFromName('test');
        expect(id).toBeDefined();
        const stub = env.CHECK.get(id);
        expect(stub).toBeDefined();
        await runInDurableObject(stub, (instance: CheckerDO) => {
            expect(instance).toBeInstanceOf(CheckerDO);
        });
    });
});

import { env, runInDurableObject, SELF } from 'cloudflare:test';
import { expect, suite, test } from 'vitest';
import { CheckerDO } from '../src/checker';

suite('first test', () => {
    test('generate a CheckerDO', async () => {
        const id = env.CHECK.idFromName('test');
        expect(id).toBeDefined();
        const stub = env.CHECK.get(id);
        expect(stub).toBeDefined();
        await runInDurableObject(stub, (instance: CheckerDO) => {
            expect(instance).toBeInstanceOf(CheckerDO);
        });
    });
});

import { env, runInDurableObject, SELF } from 'cloudflare:test';
import { expect, suite, test } from 'vitest';
import { CheckerDO } from '../src/checker';

suite('first test', () => {
    test('generate a CheckerDO', async () => {
        const id = env.CHECK.idFromName('test');
        expect(id).toBeDefined();
        const stub = env.CHECK.get(id);
        expect(stub).toBeDefined();
        await runInDurableObject(stub, (instance: CheckerDO) => {
            expect(instance).toBeInstanceOf(CheckerDO);
        });
    });
});

import { env, runInDurableObject, SELF } from 'cloudflare:test';
import { expect, suite, test } from 'vitest';
import { CheckerDO } from '../src/checker';

suite('first test', () => {
    test('generate a CheckerDO', async () => {
        const id = env.CHECK.idFromName('test');
        expect(id).toBeDefined();
        const stub = env.CHECK.get(id);
        expect(stub).toBeDefined();
        await runInDurableObject(stub, (instance: CheckerDO) => {
            expect(instance).toBeInstanceOf(CheckerDO);
        });
    });
});

wrangler.toml

wrangler.toml

contains the relevant definitions:

[[durable_objects.bindings]]
name = "CHECK"
class_name = "CheckerDO"

[[durable_objects.bindings]]
name = "CHECK"
class_name = "CheckerDO"

[[durable_objects.bindings]]
name = "CHECK"
class_name = "CheckerDO"
