testcontainers-iroha
Testcontainers image for single Iroha peer and iroha network.
Features
- run one or multiple independent iroha peers (not connected to a network) with
IrohaContainerclass. - run one or multiple independent iroha networks with
IrohaNetworkclass. All peers within a network are connected to a single network. - define custom genesis block or peer config for peer/network at run-time.
- select iroha or postgres version at run-time.

Usage
Single Peer
class SinglePeerTest {
IrohaContainer iroha = new IrohaContainer();
@BeforeAll
public void beforeAll(){
iroha.start(); // starts iroha and postgres
}
@AfterAll
public void afterAll(){
iroha.stop(); // stops iroha and postgres
}
@Test
public TestWithIroha (){
URI toriiAddr = iroha.getToriiAddress(); // iroha API host:port (torii)
IrohaAPI api = iroha.getApi(); // or use async Iroha API wrapper directly
// ...
}
}IrohaContainer starts Postgres and Iroha docker containers with given PeerConfig.
There is a default config for test purposes.
Configuration
- genesis block: see GenesisBlockBuilder.java.
- json config: see IrohaConfig.java.
- postgres config: see PostgresConfig.java.
To change default configuration:
IrohaContainer iroha = new IrohaContainer()
.withPeerConfig( /* pass config here */ );
iroha.start();
...
iroha.stop();Network Of Peers
class IrohaNetworkTest {
IrohaNetwork iroha = new IrohaNetwork(5 /* peers */);
// networks are completely independent
IrohaNetwork network2 = new IrohaNetwork(5 /* peers */)
.withNetworkName("someUniqueName");
@BeforeAll
public void beforeAll(){
iroha.start(); // starts all containers
}
@AfterAll
public void afterAll(){
iroha.stop(); // stops all containers
}
@Test
public TestWithIroha (){
List<URI> toriiAddr = iroha.getToriiAddress(); // list of iroha API host:port (torii)
List<IrohaAPI> apis = iroha.getApis(); // or list of async Iroha API wrappers, 1 per peer
// ...
}
}Configuration
To change default configuration:
IrohaNetwork network = new IrohaNetwork(5 /* peers */);
// setup shared iroha config
network.withIrohaConfig(IrohaConfig.builder()
.setMst_enable(true)
.build())
// to change genesis block (peers are added automatically)
network.addTransaction(tx);
network.start();
...
network.stop();Known Issues
If you get an Exception:
com.github.dockerjava.api.exception.DockerException: Mounts denied
You are probably on MAC and you need to add /var/folder to docker paths:
