I am creating a schedule for the workflow in a testing environment, but I encountered the following error: “CreateSchedule is unimplemented.”  
Testing is essential, but I cannot create an external server.  
Is there any way to overcome this?  
For example, using testcontainers.

Most of our SDKs now make it very easy to start a Test Workflow Environment that uses the Temporal CLI’s builtin development server (which is using the very code as the official server), as an alternative to the time-skipping test server (which is a Java based implementation of the Temporal Server, providing limited feature support). Unfortunately, our Java SDK don’t yet provide this feature out of the box. See [this feature request ticket](https://github.com/temporalio/sdk-java/issues/1804).

In the mean time, you may simply [download Temporal CLI by yourself](https://github.com/temporalio/cli#install), and [run a local Dev Server](https://github.com/temporalio/cli#start-the-server). No external/persistant database is required (the CLI’s dev server use an in-memory sqlite database). Then, in your tests, make sure to set [the `useExternalService` property](https://github.com/temporalio/sdk-java/blob/15337d9a7cfd12ca1d3096034e017a82f167ea45/temporal-testing/src/main/java/io/temporal/testing/TestEnvironmentOptions.java#L132) to `true`.
