# graph-node
## Test
1. Run `yarn` to install all dependencies.
2. Create .env file
```bash
$ cp .env.example .env
```
3. To deploy contract for example subgraph use https://github.com/deep-stack/eth-contract-tests
```bash
# In eth-contract-test repo.
$ yarn
$ yarn example:deploy
```
Use the address the contract got deployed to and set it to `EXAMPLE_CONTRACT_ADDRESS` in .env file.
3. To deploy contracts for eden subgraph use https://github.com/vulcanize/governance
4. Follow the steps in https://github.com/vulcanize/governance/tree/watcher-ts#instructions
5. Set the contract addresses for eden contracts in .env file from `deployments/localhost` directory in the governance repository.
Following are the contracts whose address needs to be set in .env file:
* EdenNetwork - EDEN_NETWORK_CONTRACT_ADDRESS
* MerkleDistributor - EDEN_NETWORK_DISTRIBUTION_CONTRACT_ADDRESS
* DistributorGovernance - EDEN_NETWORK_GOVERNANCE_CONTRACT_ADDRESS
6. Run `yarn build:example` to build the wasm files.
7. Run `yarn test`.
## Run
* Compare query results from two different GQL endpoints:
* In a config file (sample: `environments/compare-cli-config.toml`):
* Specify the two GQL endpoints in the endpoints config.
* Specify the query directory in queries config or pass as an arg. to the CLI.
* Example:
```
[endpoints]
gqlEndpoint1 = "http://localhost:8000/subgraphs/name/example1"
gqlEndpoint2 = "http://localhost:3008/graphql"
[queries]
queryDir = "../graph-test-watcher/src/gql/queries"
```
* Fire a query and get the diff of the results from the two GQL endpoints:
```bash
./bin/compare-entity --config-file <config-file-path> --query-dir [query-dir] --query-name <query-name> --block-hash <block-hash> --entity-id <entity-id> --raw-json [true | false]
```
* `config-file`(alias: `cf`): Configuration file path (toml) (required).
* `query-dir`(alias: `qf`): Path to queries directory (defualt: taken from the config file).
* `query-name`(alias: `q`): Query to be fired (required).
* `block-hash`(alias: `b`): Block hash (required).
* `entity-id`(alias: `i`): Entity Id (required).
* `raw-json`(alias: `j`): Whether to print out a raw diff object (default: `false`).
Example:
```bash
./bin/compare-entity --config-file environments/compare-cli-config.toml --query-name author --block-hash 0xceed7ee9d3de97c99db12e42433cae9115bb311c516558539fb7114fa17d545b --entity-id 0xdc7d7a8920c8eecc098da5b7522a5f31509b5bfc
```
* The program will exit with code `1` if the query results are not equal.
