+# DynamoDB Enhanced Client Test Checklist
+
+Below is the checklist required for merging DynamoDB Enhanced Client test changes.
+Please complete this checklist when making any changes to Enhanced DDB.
+
+**Instructions:**
+- Mark completed tests with [x] (e.g., [x] instead of [ ])
+- For tests not completed, provide a reason in the "Comments" column
+- If your code changes are covered by existing tests, reference the test class and method name in the Comments column (e.g., `TableSchemaTest.testFromBean()`)
+- Please copy the markdown into your PR and update it in Testing section
+- [Reference for CRUD Operations test](https://github.com/aws/aws-sdk-java-v2/blob/master/services-custom/dynamodb-enhanced/src/test/java/software/amazon/awssdk/enhanced/dynamodb/functionaltests/BasicCrudTest.java)
+- [Reference for Data Types and Null Handling](https://github.com/aws/aws-sdk-java-v2/blob/master/services-custom/dynamodb-enhanced/src/test/java/software/amazon/awssdk/enhanced/dynamodb/document/EnhancedDocumentTestData.java)
