BigtableEmulatorRule (Google Cloud Bigtable Parent 2.27.2 API)

java.lang.Object
- org.junit.rules.ExternalResource
- - com.google.cloud.bigtable.emulator.v2.BigtableEmulatorRule

All Implemented Interfaces:

org.junit.rules.TestRule
```
@BetaApi("Surface for Bigtable emulator is not yet stable")
public class BigtableEmulatorRule
extends org.junit.rules.ExternalResource
```
The BigtableEmulatorRule manages the lifecycle of the Bigtable Emulator. Before the start of a test, the emulator will be started on a random port and will be shutdown after the test finishes.
Example usage: {@literal @RunWith(JUnit4.class)} public class MyTest { {@literal @Rule} public final BigtableEmulatorRule bigtableEmulator = BigtableEmulatorRule.create(); {@literal @Test} public void testUsingEmulator() { ManagedChannel adminChannel = bigtableEmulator.getAdminChannel(); // Do something with channel } }
