Tests ===== 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. .. code:: javascript # 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.
