I have a similar issue with quantmod. I need API keys to test some
functionality and I would like the tests run regularly, so I can know
when something breaks without having to wait for a user to report the
I store the API keys in encrypted environment variable in TravisCI,
and I check for those environment variables before running the tests
that require them.
Then I added a cron job on TravisCI to run the build if there hasn't
been a build in the past 24 hours. That solves the problem adequately
for my purposes without adding any burden to CRAN. Hopefully it works
for your purposes too.
