containerExecuteStructureTests

In this step Container Structure Tests are executed.

Description

This testing framework allows you to execute different test types against a Docker container, for example: - Command tests (only if a Docker Deamon is available) - File existence tests - File content tests - Metadata test

Usage

We recommend to define values of step parameters via .pipeline/config.yml file.
In this case, calling the step is essentially reduced to defining the step name.
Calling the step can be done either in an orchestrator specific way (e.g. via a Jenkins library step) or on the command line.

library('piper-lib-os')

containerExecuteStructureTests script: this
piper containerExecuteStructureTests

Prerequisites

Test configuration is available.
