Integration Test

Clone the cronos repository

git clone https://github.com/crypto-org-chain/cronos.git

Install nix

https://nixos.org/download.html

Multi-user installation:

sh <(curl -L https://nixos.org/nix/install) --daemon

Make sure the following line has been added to your shell profile (e.g. ~/.profile):

source ~/.nix-profile/etc/profile.d/nix.sh

Then re-login shell, the nix installation is completed.

Install cachix

nix-env -iA cachix -f https://cachix.org/api/v1/install

Configure Binary Caches

Binary caches will save a lot of build times.

cachix use cronos
cachix use dapp  # it's necessary to use dapp's binary cache on new macos system.

Run All Integration Tests

make run-integration-tests

Customize The Test Runner

To customize the test runner, you can also issue commands separately.

Enter nix-shell

It'll prepare all dependencies.

$ nix-shell integration_tests/shell.nix
<nix-shell> $

Compile Test Contracts

$ cd integration_tests/contracts
$ HUSKY_SKIP_INSTALL=1 npm install
$ npm run typechain
$ cd ../../

Run pytest

We use pytest to discover the test cases and run them, follow pytest doc for more options.

You can invoke pytest after entering the nix shell:

$ cd integration_tests
$ pytest -s -vv

You can use -k to select test cases by patterns in name:

$ cd integration_tests
$ pytest -k test_basic

Some test cases will run on both geth and cronos, you can also select the platform to run using -k:

$ cd integration_tests
$ # run against cronos only
$ pytest -k cronos
$ # run against geth only
$ pytest -k geth

Print test config

$ jsonnet integration_tests/configs/default.jsonnet | yq -P
