We've been using (abusing?) Netlify for testing building example sites as integration tests.

This has a few problems:

• Netlify logs aren't easily accessible to people other than me
• Netlify limits how fast we can build sites
• It's not obvious if a site fails because Netlify adding a comment on every site build got super noisy so I had to turn it off. So sites can stop building and we won't notice it for a while.
• There's a lot of manual work to setup each new site — would much prefer it's automatic — just build every site in the examples directory
• We can't extend what we're testing e.g. would be nice to calculate hash of every generated file and warn if things change.
• Also really want to add build & client performance testing — track build length, max-memory used, various frontend performance metrics on e.g. webpagetest
• Also would like to add automated client testing w/ Chrome Puppeteer. Much easier to do this if we control the infrastructure
