Examples with BlockchainAccess org.eclipse.winery.accountability.blockchain.BlockchainAccess used on opensource projects

Example 1 with BlockchainAccess

use of org.eclipse.winery.accountability.blockchain.BlockchainAccess in project winery by eclipse.

the class AccountabilityManagerImplTest method setUp.

@BeforeEach
public void setUp() throws Exception {
    BlockchainAccess blockchainAccess = BlockchainFactory.getBlockchainAccess(BlockchainFactory.AvailableBlockchains.TEST, null);
    ImmutableStorageProvider storageProvider = ImmutableStorageProviderFactory.getStorageProvider(ImmutableStorageProviderFactory.AvailableImmutableStorages.TEST, null);
    this.provenance = new AccountabilityManagerImpl(blockchainAccess, storageProvider);
}

Example 2 with BlockchainAccess

use of org.eclipse.winery.accountability.blockchain.BlockchainAccess in project winery by eclipse.

the class AccountabilityManagerImplIntegrationTest method setUp.

@BeforeEach
public void setUp() {
    AccountabilityConfigurationManager.getInstance().setDefaultKeystore();
    Environments.getInstance().getAccountabilityConfig().setEthereumPassword("winery");
    Environments.getInstance().getAccountabilityConfig().setGethUrl("http://127.0.0.1:8545");

        Environments.getInstance().getAccountabilityConfig().setEthereumAuthorizationSmartContractAddress(deployer.deployAuthorization());
        // reset the contents of the accountability layer so older, possibly incompatible instances are nullified.
        BlockchainFactory.reset();
        ImmutableStorageProviderFactory.reset();
        // create new instances
        BlockchainAccess blockchainAccess = BlockchainFactory.getBlockchainAccess(BlockchainFactory.AvailableBlockchains.ETHEREUM, Environments.getInstance().getAccountabilityConfig());
