easygraphql-load-tester is the new version of easygraphql-load-tester; now the configuration is minimum, it only requires a JSON file.

It uses Artillery.io under the hood.

How to run it:

If you want do download the latest version of the GraphQL schema, run this command with out flag

$ npx easygraphql-lt <CONFIG_FILE>.json

Also, if you have a local copy of the schema to test, you can set the flag --localSchema and it'll display a list of files that might be the schema on the selected folder.

$ npx easygraphql-lt <CONFIG_FILE>.json --localSchema
