+# csv_not_null.test - .test file for MySQL regression suite
+# Purpose:  To test the behavior of the CSV engine
+#           Bug#31473 resulted in strict enforcement of non-nullable
+#           columns in CSV engine.
+# NOTE:     Main functionality tested - NOT NULL restrictions on CSV tables
+#           CREATE, INSERT, and UPDATE statements 
+#           ALTER statements in separate file due to BUG#33696
