GTF configuration options

Greengrass Testing Framework (GTF) enables you to configure certain parameters during the launch of the end-to-end testing process to orchestrate the test flow. You can specify these configuration options as CLI arguments for the GTF standalone JAR.

  • csr-path – The path for the CSR using which the device certificate will be generated.

  • device-mode – The target device under test. Defaults to local device.

  • env-stage – Targets the deployment environment of Greengrass. Defaults to production.

  • existing-device-cert-arn – The arn of an existing certificate that you want to use as a device certificate for Greengrass.

  • feature-path – File or directory containing additional feature files. Default is no additional feature files are used.
