Do we have (other) tests to ensure that extra spaces in situations like these,
etc. (e.g., no trailing commas in enum declarations) are parsed correctly?

Yes, the parser has tests that covers at least the two cases you mentioned here.

 module sample;
 
 const uint64 kLong = 4405;
 
 enum Enum {
-  VALUE
+  VALUE,
 };
 
 interface Provider {
   EchoString(string a) => (string a);
   EchoStrings(string a, string b) => (string a, string b);
   EchoMessagePipeHandle(handle<message_pipe> a) => (handle<message_pipe> a);
   EchoEnum(Enum a) => (Enum a);
   EchoInt(int32 a) => (int32 a);
 };
 
 interface IntegerAccessor {
   GetInteger() => (int64 data, [MinVersion=2] Enum type);
   [MinVersion=1]
   SetInteger(int64 data, [MinVersion=3] Enum type);
 };
 
 // Used for testing that structs are generated for request params and response
 // params.  Also used to test the generated method ordinals.
 interface SampleInterface {
   SampleMethod1@1(int32 in1, string? in2) => (string? out1, Enum out2);
   SampleMethod0@0();
   SampleMethod2@2();
 };
