Integration Tests

Integration tests are located in this crate. Each test group can be found under a different file in tests/.

Contracts for tests are found in contracts/.

The full integration tests flow can be executed with the run.sh script, which is used like this:

$ ./run.sh --help                
        Usage: ./run.sh [OPTIONS]
        Options:
          --sudo         Use sudo for docker compose commands.
          --steps ARG    Space separated list of steps to do.
                         Default: "setup gendata tests cleanup".
          --tests ARG    Space separated list of tests to run.
                         Default: "rpc".
          -h | --help    Show help

Steps

1. Setup: Start the docker container that runs a fresh geth in dev mode, via docker compose.
2. Gendata: Run the gen_blockchain_data binary found in src/bin/gen_blockchain_data.rs which compiles the contracts, deploys them, and executes transactions; in order to generate blocks with a variety of data and transactions to be used in the tests. The compiled output of the contracts will be written as json files in contracts next to the solidity source. After completion, gendata_output.json will be generated with details of the executed transactions to be used as input vectors for the tests.
3. Tests: Run the specified tests groups.
4. Cleanup: Remove the geth docker container.

By default the run.sh script runs all the steps. Specifying a smaller combination of steps can be very useful for development: you can run the setup and gendata once, and then iterate over the tests step to debug specific functions being tested.

Lib

Functions and constant parameters shared both in the gendata step and the tests themselves are defined in lib.rs.

Requirements

The following software needs to be installed to run the integration tests script:

• docker compose
• Rust toolchain
• solc version 0.7.x or 0.8.x
