Comment 4 for bug 1619776

Tested in an up-to-date xenial virtual machine with kvm.

 * Installed snapcraft, snapcraft-examples and snapcraft-parser
 * Enabled -proposed
 * Updated snapcraft, snapcraft-examples and snapcraft-parser to 2.16.

I ran the following tests:

Variables:

  Build and run a snap using snapcraft variables in the build.
  Build a snap using snapcraft variables in the yaml.

Plugins:

  Build python2 and python3 snaps and check that they include no .pyc, .pth nor pycache.
  Build a nodejs snap in arm64.

Grade:

  Build snaps with grade devel and stable.
  Push the snaps to the store and release them.

Cleanbuild:

  Make a faulty snap and run cleanbuild with --debug.

Errors:

  Build a snap with file conflicts.

Store:

  Register a private snap.
  Push a private snap.
  Release a private snap.

I'm going to mark this as verified. Thanks Martin!
