# Datasource fixtures The file mockingbird-schema.json is a schema for generating fake data using the Mockingbird CLI. The CLI is installed via npm: ``` npm install -g @tinybirdco/mockingbird ``` The command I'm currently using to generate the data is: ``` mockingbird-cli tinybird --schema ghost/tinybird/datasources/fixtures/mockingbird-schema.json --endpoint gcp_europe_west3 --token xxxx --datasource analytics_events --eps 50 --limit 5000 ```
