- Use better error messages with more context. - Unify their validation logic and share tests. - Validate also type of the name. - Refactor node (Script/Category) parser tests for easier future changes and cleaner test code (using `TestBuilder` to do dirty work in unified way). - Add more tests. Custom `Error` properties are compared manually due to `chai` not supporting deep equality checks (chaijs/chai#1065, chaijs/chai#1405).
