Usage

To use a test you just need to import the relevant test method and call it on a CRDT implementation. If you are testing against a specific CRDT (for example G-Counter) then you do not need to test against the general CRDT tests since those are included in the specific tests. The general tests are to assist with the creation of abitrary CRDTs that may not have a specific test ready for them.

Most of these tests are created for implementations that use arbitrary data types, if the implementation is for a specific data type then a specific test should also be created for it.

Tests

CRDT

import { createCRDTTest } from "@organicdesign/crdt-tests";

This test is a general CRDT test for CRDTs conforming to the CRDT interface. This will check that functionality of it works.

Sync

import { createSyncronizeTest } from "@organicdesign/crdt-tests";

This test checks that the synchronization functionality of a CRDT works.

Broadcast

import { createBroadcastTest } from "@organicdesign/crdt-tests";

This test checks that the broadcast functionality of a CRDT works, given that the CRDT implements this optional feature.

Serialize

import { createSerializeTest } from "@organicdesign/crdt-tests";

This test checks the the serialization functionality of a CRDT works give that the CRDT implements this optional feature.

G-Counter

Status: Basic

import { createGCounterTest } from "@organicdesign/crdt-tests";

This test is for a G-Counter CRDT that implements the CRDT & MCounter interfaces.

PN-Counter

Status: Basic

import { createPNCounterTest } from "@organicdesign/crdt-tests";

This test is for a PN-Counter CRDT that implements the CRDT & BCounter interfaces.

G-Set

Status: Incomplete

import { createGSetTest } from "@organicdesign/crdt-tests";

This test is for a G-Set CRDT that implements the CRDT & MSet interfaces.

MV-Register

Status: Incomplete

import { createMVRegisterTest } from "@organicdesign/crdt-tests";

This test is for a MV-Register CRDT that implements the CRDT & MVRegister interfaces.

LWW-Register

Status: Incomplete

import { createLWWRegisterTest } from "@organicdesign/crdt-tests";

This test is for a LWW-Register CRDT that implements the CRDT & BRegister interfaces.

LWW-Map

Status: Incomplete

import { createLWWMapTest } from "@organicdesign/crdt-tests";

This test is for a LWW-Map CRDT that implements the CRDT & BMap interfaces.

CRDT-Map

Status: Incomplete

import { createLWWMapTest } from "@organicdesign/crdt-tests";

This test is for a CRDT-Map CRDT that implements the CRDT & MMap interfaces.

To-Do

This package contains basic testing systems for CRDTs but there probably are better ways to setup the tests (espicially after the interfaces version 4.0.0 change), contribution would be most welcome to improve these tests.
