The try-with-resources block is used to create a SpannerEmulatorContainer instance and start the container. The start() method of SpannerEmulatorContainer class is used to start the container. The start() method is automatically called when the SpannerEmulatorContainer instance is created, so we don’t need to call the start() method explicitly. The start() method is used to start the container if the container is not started. The start() method is idempotent, so it can be called multiple times without any side effects. The start() method is implemented by the GenericContainer
