This PR looks good! The test name changes are consistent with the existing patterns in the codebase. I verified that:

✅ All 24 test functions have been properly renamed with the TestParser_ prefix
✅ Tests are passing (go test ./language/parser/ succeeds)
✅ This follows the established naming convention used by other packages in the language/ directory:

• lexer_test.go uses TestLexer_ prefix
• printer_test.go uses TestPrinter_ prefix
• visitor_test.go uses TestVisitor_ prefix
• schema_parser_test.go uses TestSchemaParser_ prefix

The changes are purely cosmetic and help maintain consistency across the codebase for compatibility with the GraphQL.js reference implementation.
