+# For Developers
+
+> [!NOTE]
+
+> In this project, we manage such test code under the `testdata` directory to avoid adding dependencies  on libraries that are only needed for testing to the top `go.mod` file. Therefore, if you want to add test cases that use 3rd party libraries, please add the test code to the `testdata` directory.
