ComponentWalker
is a major part of the update schematics and we should verify that external resource files are resolved properly. All test-cases currently just use inline stylesheets or templates.color
helper function.StringLiteral
's text content.Note: Technically we could also create real files (like with the test-cases), but I don't see a reason why we need to save up dependencies if
mock-fs
