Solidity tests

Increasingly difficult tests are provided:

• Basic: simple Counter example, for basic calls, transactions, and events
• Initialize: initialization contract and tests from aragonOS
• Initialize (Buidler): initialization contract and tests from aragonOS, using buidler
• Proxy: depositable delegate proxy contract and tests from aragonOS
• Staking: Staking contracts and full test suite from aragon/staking

Quick start

Prerequisite: in the repo's root, run make install to install the ethermintd and ethermintd binaries. When done, come back to this directory.

Prerequisite: install the individual solidity packages. They're set up as individual reops in a yarn monorepo workspace. Install them all via yarn install.

To run the tests, you can use the test-helper.js utility to test all suites under ganache or ethermint network. The test-helper.js will help you spawn an ethermintd process before running the tests.

You can simply run yarn test --network ethermint to run all tests with ethermint network, or you can run yarn test --network ganache to use ganache shipped with truffle. In most cases, there two networks should produce identical test results.

If you only want to run a few test cases, append the name of tests following by the command line. For example, use yarn test --network ethermint basic to run the basic test under ethermint network.

If you need to take more control, you can also run ethermintd using:

./init-test-node.sh

You will now have three ethereum accounts unlocked in the test node:

• 0x3b7252d007059ffc82d16d022da3cbf9992d2f70 (Validator)
• 0xddd64b4712f7c8f1ace3c145c950339eddaf221d (User 1)
• 0x0f54f47bf9b8e317b214ccd6a7c3e38b893cd7f0 (user 2)

Keep the terminal window open, go into any of the tests and run yarn test-ethermint. You should see ethermintd accepting transactions and producing blocks. You should be able to query for any transaction via:

• ethermintd query tx <cosmos-sdk tx>
• curl localhost:8545 -H "Content-Type:application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_getTransactionByHash","params":["<ethereum tx>"],"id":1}'

From here, in your other available terminal, And obviously more, via the Ethereum JSON-RPC API).

When in doubt, you can also run the tests against a Ganache instance via yarn test-ganache, to make sure they are behaving correctly.

Test node

The init-test-node.sh script sets up ethermint with the following accounts:

• ethm10jmp6sgh4cc6zt3e8gw05wavvejgr5pwtu750w (Validator)
  • 0x7cB61D4117AE31a12E393a1Cfa3BaC666481D02E
• ethm1cml96vmptgw99syqrrz8az79xer2pcgp767p9e (User 1)
  • 0xC6Fe5D33615a1C52c08018c47E8Bc53646A0E101
• ethm1jcltmuhplrdcwp7stlr4hlhlhgd4htqhgjpff2 (user 2)
  • 0x963EBDf2e1f8DB8707D05FC75bfeFFBa1B5BaC17

Each with roughly 100 ETH available (1e18 photon).

Running ethermintd keys list --keyring-backend=test should output:

[
  {
    "name": "localkey",
    "type": "local",
    "address": "ethm18de995q8qk0leqk3d5pzmg7tlxvj6tmsku084d",
    "pubkey": "ethpub1pfqnmk6pq3ycjs34vv4n6rkty89f6m02qcsal3ecdzn7a3uunx0e5ly0846pzg903hxf2zp5gq4grh8jcatcemfrscdfl797zhg5crkcsx43gujzppge3n"
  },
  {
    "name": "user1",
    "type": "local",
    "address": "ethm1mhtyk3cj7ly0rt8rc9zuj5pnnmw67gsapygwyq",
    "pubkey": "ethpub1pfqnmk6pq3wrkx6lh7uug8ss0thggact3n49m5gkmpca4vylldpur5qrept57e0rrxfmeq5mp5xt3cyf4kys53qcv66qxttv970das69hlpkf8cnyd2a2x"

  }
]

And running:

curl localhost:8545 -H "Content-Type:application/json" -X POST --data '{"jsonrpc":"2.0","method":"eth_accounts","params":[],"id":1}'

Should output:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": [
    "0x3b7252d007059ffc82d16d022da3cbf9992d2f70",

    "0x0f54f47bf9b8e317b214ccd6a7c3e38b893cd7f0"
