+# fast-fe-ut.sh — Fast FE unit test runner
+#
+# Usage:
+#   ./fast-fe-ut.sh                                         # Run all UT
+#   ./fast-fe-ut.sh org.apache.doris.utframe.Demo           # Run a specific test class
+#   ./fast-fe-ut.sh DemoTest#testMethod1+testMethod2         # Run specific test methods
+#   ./fast-fe-ut.sh org.apache.doris.Demo,org.apache.doris.Demo2  # Run multiple test classes
+#
+# How it works:
+#   1. Fast incremental compile (main + test) via tools/fast-compile-fe.sh
+#   2. If compilation succeeds → run tests via mvn surefire:test (skips Maven compile)
+#   3. If compilation fails   → fall back to run-fe-ut.sh --run <test_spec>
+#
+# Limitations:
+#   - EXTRA_FE_MODULES triggers automatic fallback (fast-compile-fe.sh only handles fe-core)
+#   - Compilation failure triggers automatic fallback
+#   - Changes outside fe-core/src/main/java (e.g. fe-common, test resources, Nereids
+#     pattern generation inputs) are NOT auto-detected.  Run a full Maven build first
+#     when making those kinds of changes.
