I also just switch the PATH.

I actually use Herbert's other wonderful tool: the Ubuntu PPAs for GHC. Then I just switch by PATH to point to whichever version of GHC I want to test at at that time.

Before I switched to the PPAs, I simply installed multiple versions of GHC in their own directories under /opt.

That is neat!

But I would rather have a solution that don't involve The Cloud, which I can run locally without setting up a local travis.

Seems like the time to learn docker have now come :-)

Common best practice seems to be to support the last two haskell platform releases, and that's pretty easy to test against.

Actually, how do you do that?

It's a shame that the platform is not a 'hackage' package, otherwise I could simply install it in a sandbox...
But how can I test my app for a specific platform without reinstalling my local/global DB?

For now I'm going on the platform github repo to get the versions, I put them as lower bound and then I use Omari's sunlight.
