Testing Ethereum ContractsΒΆ

You can run specs with embark test, it will run any test files under test/.

Embark includes a testing lib to fastly run & test your contracts in a EVM.

# test/simple_storage_spec.js

var assert = require('assert');
var Embark = require('embark');
var EmbarkSpec = Embark.initTests();
var web3 = EmbarkSpec.web3;

describe("SimpleStorage", function() {
  before(function(done) {
    var contractsConfig = {
      "SimpleStorage": {
        args: [100]
      }
    };
    EmbarkSpec.deployAll(contractsConfig, done);
  });

  it("should set constructor value", function(done) {
    SimpleStorage.storedData(function(err, result) {
      assert.equal(result.toNumber(), 100);
      done();
    });
  });

  it("set storage value", function(done) {
    SimpleStorage.set(150, function() {
      SimpleStorage.get(function(err, result) {
        assert.equal(result.toNumber(), 150);
        done();
      });
    });
  });

});

Embark uses Mocha by default, but you can use any testing framework you want.
