-=== JNDI
-
-The `org.springframework.mock.jndi` package contains a partial implementation of the JNDI
-SPI, which you can use to set up a simple JNDI environment for test suites or stand-alone
-applications. If, for example, JDBC `DataSource` instances get bound to the same JNDI
-names in test code as they do in a Jakarta EE container, you can reuse both application code
-and configuration in testing scenarios without modification.
-
-WARNING: The mock JNDI support in the `org.springframework.mock.jndi` package is
-officially deprecated as of Spring Framework 5.2 in favor of complete solutions from third
-parties such as https://github.com/h-thurow/Simple-JNDI[Simple-JNDI].
