This is based off of the #206 PR, but it's not necessary. It's also not time sensitive, but a good to have...

Is there a reason why you opted to skip the GPG tests on Windows? There might be GPG behavior on Windows that we'd want to catch via these integration tests. It might be better to install GPG in Appveyor and not skip tests. We can look at how other projects make sure that a modern version of GPG is installed. See this appveyor config for an example. There is also a decent help page for installing GPG in Appveyor:

Note: This pull request contains commits for parameter substitution. It's hard to judge what's relevant to this pull request (GPG testing on Windows) and what should be ignored (parameter substitution).

Agreed. Will provide something soon.

I will clarify in the description, but it's not specific to windows, but rather installations that do not have windows installed and want to run the tests. This speeds up the suite execution.

Yes, I'll review this, although that may be more relevant for #207

Right. Now that ParamSubs is there, I'll rebase and re-push.

@awwad @trishankatdatadog could I get a review on this PR? I don't want it to grow stale...

[SantiagoTorres]

These tests will continue failing until we merge #211

I guess it's fine. Like @vladimir-v-diaz, I'm not a big fan of skipping GPG, but this should be fine.
