Embark 5.1

Interfaces & Libraries Configuration

Embark 5.1 adds two new configuration settings for Smart Contract configuration:

interfaces - Any Smart Contract that represent an interface or is used for inheritance libraries - Any Smart Contract that is used as a library

This makes the configuration less redundant in cases where otherwise the deploy property has been set to false, such as:

deploy: {
  Ownable: {
    deploy: false
  },
  ...
}

The above can now be done via:

interfaces: ['Ownable'],
deploy: {
  ...
}

Find the complete documentation here.

getEvmVersion for conditional tests

Embark tests now include a helper getEvmVersion that can be used to consult what EVM the tests are being run on. This is useful when you have certain tests that can only be run in a particular type of node, but you still want to be able to run tests everywhere without them breaking.

For example:

  it("cannot bid after 5 minutes", async () => {
    const evmVersion = await global.getEvmVersion();
    if (evmVersion.indexOf("TestRPC") === -1) return;

    increaseTime(5000)

    await assert.reverts(Auction.methods.bid(), {from: web3.eth.defaultAccount}, 'Returned error: VM Exception while processing transaction: cannot bid after auction expired');
  })

Nethermind plugin

Embark now comes with a Nethermind plugin. More info about the plugin can be found here
