# jest-gas-reporter

A simple jest reporter that reports the gas used by various calls to ethereum contracts.

It uses the `json` files compiled by truffle parse transactions that occured on `ganache` and show gas usage of different contract functions.

--------------------  --------------------------  -----  -------  -------  -----------
TestContract          deposit                     20     31032    46032    35532

```

## Configuration

Just add jest-gas-reporter to reporters in your jest config. By default `jest-gas-reporter` assume that contract json files are located in `./build/contracts`

```
 "reporters": ["default","jest-gas-reporter"]
```

If you want specify a folder where the contracts are located. `jest-gas-reporter` accepts a `contractArtifactFolder` option.

```
"reporters": ["default",
      ["jest-gas-reporter",
        { "contractArtifactFolder":"output/contract" }
      ]
    ]
```
