When embark was running as module inside the dapp’s `node_modules`, the tests were failing due to several issues: 1. `web3` was not being set in the global namespace of vm2. `EmbarkJS.Blockchain.setProvider` was therefore failing because it relies on `global.web3` to be set. I guess somehow this works when the test app was running in a child tree of the executing program. maybe this is a security feature of vm2, but i’m not sure. 2. `embarkjs` provider code being injected to the vm twice. This really was the initial point of failure, as this piece of code is requiring embarkjs, so i’m assuming, but again not sure, that maybe it was getting a second instance of `EmbarkJS` which did not have it’s providers set up correctly (hence the error with `ENS provider not set`). Fixes for those issues in this PR: 1. To circumvent the web3 issue, we are now setting `global.web3` for tests only (the global web3 accessible in the tests), and `web3` is now explicitly passed in to `EmbarkJS.Blockchain.setProvider` 2. To fix the `embarkjs` code being called twice, we are not re-injecting this code to the VM during test initialisations
What is Embark
Embark is a framework that allows you to easily develop and deploy Decentralized Applications (DApps).
A Decentralized Application is a serverless html5 application that uses one or more decentralized technologies.
Embark currently integrates with EVM blockchains (Ethereum), Decentralized Storages (IPFS), and Decentralized communication platforms (Whisper and Orbit). Swarm is supported for deployment.
With Embark you can:
Blockchain (Ethereum)
- Automatically deploy contracts and make them available in your JS code. Embark watches for changes, and if you update a contract, Embark will automatically redeploy the contracts (if needed) and the dapp.
- Contracts are available in JS with Promises.
- Do Test Driven Development with Contracts using Javascript.
- Keep track of deployed contracts; deploy only when truly needed.
- Manage different chains (e.g testnet, private net, livenet)
- Easily manage complex systems of interdependent contracts.
Decentralized Storage (IPFS, Swarm)
- Easily Store & Retrieve Data on the DApp through EmbarkJS. Including uploading and retrieving files.
- Deploy the full application to IPFS or Swarm.
- Import and deploy contracts hosted on Swarm.
Decentralized Communication (Whisper, Orbit)
- Easily send/receive messages through channels in P2P through Whisper or Orbit.
Web Technologies
- Integrate with any web technology including React, Foundation, etc..
- Use any build pipeline or tool you wish, including grunt, gulp and webpack.
