Add a new test suite for user data get/set operations on WrenVM, including a Wren script that validates default NULL userData, retrieval after VM creation, and mutation via wrenSetUserData. Also reorder the vm parameter in WrenErrorFn callback signature and all its call sites to match the convention used by other callback types, updating the typedef, the reportError implementation, and all invocations in the compiler and debug modules. Include the new source and header files in the Xcode project build configuration.
This contains the automated validation suite for the VM and built-in libraries.
-
benchmark/- Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself. -
core/- Tests for the built in core library, mainly methods on the core classes. If a bug is inwren_core.corwren_value.c, it will most likely break one of these tests. -
language/- Tests of the language itself, its grammar and runtime semantics. If a bug is inwren_compiler.corwren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes. -
limit/- Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
