#### integration testing

This repository contains integration tests that validate the argo stack.

It leverages the argopkgs repo, but overrides some sources in it with
their master branch counterparts. see file `default.nix` for details.

The intended usage is to override (some of) the source(s) with WIP
version(s), as part of development or continuous integration. This
gitlab CI snippets shows how to do this on a nix-enabled runner. Mind
that this setup tracks argotest master.

``` {.yml}
integration.test:
  stage: test
  script:
    - BUILD=$PWD
    - git clone https://xgitlab.cels.anl.gov/argo/argotest.git
    - cd argotest
    - nix-shell -A test --run "./argotk.hs helloworld" --arg nrm-src ../.
  artifacts:
    paths:
      - argotest/cmd_err.log
      - argotest/cmd_out.log
      - argotest/daemon_out.log
      - argotest/daemon_out.log
      - argotest/nrm.log
      - argotest/time.log
    expire_in: 1 week
  except:
    - /^wip\/.*/
    - /^WIP\/.*/
  tags:

```

Standalone usage: example with the nrm source in `../`.

``` {.bash}
nix-shell -A test --arg nrm-src ../nrm
nix-shell $ ./argotk.hs --help
```

Output:

``` {.txt}
