# Zombienet tests

_The content of this directory is meant to be used by Parity's private CI/CD infrastructure with private tools. At the
moment those tools are still early stage of development and we don't know if / when they will available for public use._

## Contents of this directory

`parachains` At the moment this directory only have one test related to parachains: `/parachains-smoke-test`, that check
    the parachain registration and the block height.

## Running tests locally

To run any test locally use the native provider (`zombienet test -p native ...`) you need first build the binaries. They
are:

- `adder-collator` -> `polkadot/target/testnet/adder-collator`
- `malus` -> `polkadot/target/testnet/malus`
- `polkadot` -> `polkadot/target/testnet/polkadot`, `polkadot/target/testnet/polkadot-prepare-worker`,
  `polkadot/target/testnet/polkadot-execute-worker`
- `polkadot-collator` -> `cumulus/target/release/polkadot-parachain`
- `undying-collator` -> `polkadot/target/testnet/undying-collator`

To build them use:
- `adder-collator` -> `cargo build --profile testnet -p test-parachain-adder-collator`
- `undying-collator` -> `cargo build --profile testnet -p test-parachain-undying-collator`
- `malus` -> `cargo build --profile testnet -p polkadot-test-malus`
- `polkadot` (in the Polkadot repo) and `polkadot-collator` (in Cumulus repo) -> `cargo build --profile testnet`

One solution is to use the `.set_env` file (from this directory) and fill the `CUSTOM_PATHS` before _source_ it to patch
the PATH of your system to find the binaries you just built.

E.g.:
```
$ cat .set_env
(...)
# by the order of this array
CUSTOM_PATHS=(
  "~/polkadot/target/release"
  "~/polkadot/target/testnet"
  "~/cumulus/target/release"
)
(...)

source .set_env
```

Then you have your `PATH` customized and ready to run `zombienet`. **NOTE**: You should need to do this ones per
 terminal session, since we are patching the `PATH` and re-exporting. **Or** you can also `source` this file in your
 `.bashrc` file to get executed automatically in each new session.

Example:

You can run a test locally by executing:
```sh
zombienet test -p native 0001-parachains-pvf.zndsl
```

setup.
