# Interop tests implementation

This folder defines the implementation for the interop tests.

# Running this test locally

You can run this test locally by having a local Redis instance and by having
another peer that this test can dial or listen for. For example to test that we
can dial/listen for ourselves we can do the following:

1. Start redis (needed by the tests): `docker run --rm -it -p 6379:6379
   redis/redis-stack`.
2. In one terminal run the dialer: `REDIS_ADDR=localhost:6379 ip="0.0.0.0"
   transport=quic-v1 security=quic muxer=quic is_dialer="true" cargo run --bin ping`
3. In another terminal, run the listener: `REDIS_ADDR=localhost:6379
   ip="0.0.0.0" transport=quic-v1 security=quic muxer=quic is_dialer="false" cargo run --bin ping`


To test the interop with other versions do something similar, except replace one
of these nodes with the other version's interop test.

# Running all interop tests locally with Compose

To run this test against all released libp2p versions you'll need to have the
(libp2p/test-plans)[https://github.com/libp2p/test-plans] checked out. Then do
the following (from the root directory of this repository):

1. Build the image: `docker build -t rust-libp2p-head . -f interop-tests/Dockerfile`.
1. Build the images for all released versions in `libp2p/test-plans`: `(cd <path to >/libp2p/test-plans/multidim-interop/ && make)`.
1. Run the test:
```
RUST_LIBP2P="$PWD"; (cd <path to >/libp2p/test-plans/multidim-interop/ && npm run test -- --extra-version=$RUST_LIBP2P/interop-tests/ping-version.json --name-filter="rust-libp2p-head")
```
