This repo offers scripts to help quickly test code against any node-mapnik release.
Install a node-mapnik version:
./install.sh 3.4.11
Then test a given script using that version:
node runner.js mapnik-versions/v3.4.11 ./color.js
Current expectation of that test script, for example, is to throw an error like: Error: Failed to parse color: "#ffffff 50"
which did not happen with versions of node-mapnik before v3.4.8
