Thanks for taking the time to help us build Solid 🎉
The most important part of our test suite is the directory test/cases.
Inside test/cases/ we have input.liquid files that are tested against Solid and against the Liquid gem.
Whenever possible we want to include a new test case that covers the new feature that was added or bug that has been fixed. So if it makes sense please include a new test case or change an existing one that makes sense.
