Interoperability Tests for IPFS

Interoperability tests for IPFS Implementations

This repository will be used for interop tests. Please jump into the issues if you'd like to help out setting this up!

Usage

Install

$ npm install -g ipfs-interop

Run the tests

$ ipfs-interop

Run a particular test locally

$ node bin/ipfs-interop.js -- -t node --grep {substring-test-name}

Testing with different versions of go/js IPFS

As a project

This module declares peer dependencies of ipfs, ipfs-http-client and go-ipfs so if you have ipfs-interop as a dependecy of your project, simply add the extra IPFS dependencies:

{
  "name": "my-project",
  "scripts": {
    "interop": "ipfs-interop"
  },
  "dependencies": {
    "go-ipfs": "...",
    "ipfs": "...",
    "ipfs-http-client": "...",
    "ipfs-interop": "..."
  }
}

Then run:

$ npm run interop

As environmental variables

Specify the following environmental variables to control which versions of IPFS ipfs-interop uses when installed globally:

• IPFS_GO_EXEC A path to a go-IPFS binary
• IPFS_JS_EXEC A path to /src/cli.js inside a js-IPFS install
• IPFS_JS_MODULE A path to a js-IPFS install
• IPFS_JS_HTTP_MODULE A path to a ipfs-http-client install (optional)

Then run:

$ npm install -g ipfs-interop
$ IPFS_GO_EXEC=/path IPFS_JS_EXEC=/path IPFS_JS_MODULE=/path IPFS_JS_HTTP_MODULE=/path ipfs-interop

As a custom runtime

If you want to run interop on CI against specific repo and git revision of go-ipfs or js-ipfs* then set everything up in ./scripts/custom-runtime.sh and enable it by uncommenting env: IPFS_(..) definitions in .github/workflows/test.yml

If you want to test against unrelased things locally, make sure the same env variables are set on your machine.

For example, to run pubsub tests against go-ipfs and js-ipfs revision defined in ./scripts/custom-runtime.sh, one can:

export IPFS_GO_EXEC=/tmp/go-ipfs/cmd/ipfs/ipfs
export IPFS_JS_EXEC=/tmp/js-ipfs/packages/ipfs/src/cli.js
export IPFS_JS_MODULE=/tmp/js-ipfs/packages/ipfs/dist/cjs/src/index.js
export IPFS_JS_HTTP_MODULE=/tmp/js-ipfs/packages/ipfs-http-client/dist/cjs/src/index.js
./scripts/custom-runtime.sh
node bin/ipfs-interop.js -- -t node --grep "pubsub"

Releasing a new version

This repo does not use aegir for releases. Use npm directly and publish entire root (CI in go-ipfs requires it).

npm version [major|minor|patch]
npm publish
npm push origin && npm push origin v[N.N.N]

Interop release process for when breaking changes are introduced

1. Get branches of go-ipfs and js-ipfs working together in interop locally using environment variables to point at the local versions
2. In this repo make a branch containing the interop changes as well as setting the go/js-ipfs commit hashes to be used by CI. Merge to master.
3. Update go-ipfs and js-ipfs branches to use interop/master instead of whatever is released
4. Release go and js-ipfs (not necessarily together) and after each is released (or RC'd) bump interop to use the release instead of the commit hash
5. Release interop
6. Bump go and js-ipfs to use released interop instead of master
