Singularity Container Testing Environment

This repo contains Singularity containers used for testing other Singularity containers.

Usage

NOTE: all scripts must be run with sudo

  1. Clone this repository
  2. Run build_full.sh

  • This will first build an image which contains Golang and Singularity, then build an image from that with the container-structure-test and singolang libraries installed. Note that this is a custom version of container-structure-test extended for use with Singularity.

  • If you need to update the libraries and already have the base container built, run build_partial.sh instead

  1. Run run.sh for a quick test run. All test case should pass.

Running tests on your own containers

The singularity_testenv.sif container runscript accepts arguments to run tests on any Singularity container. The first argument is the image file, and the second is the config file. For example, here is the command used in run.sh

sudo singularity run singularity_testenv.sif lolcow_latest.sif test_config.yaml

The config file must be a .yaml file formatted according to the documentation of Google's container-structure-test framework. Note that the Singularity driver does not yet support Metadata or License tests.
