Package io.cloudstub.junit

Class FaultInjectionExtension

java.lang.Object
io.cloudstub.junit.FaultInjectionExtension
All Implemented Interfaces:
org.junit.jupiter.api.extension.AfterTestExecutionCallback, org.junit.jupiter.api.extension.BeforeTestExecutionCallback, org.junit.jupiter.api.extension.Extension
public final class FaultInjectionExtension extends Object implements org.junit.jupiter.api.extension.BeforeTestExecutionCallback, org.junit.jupiter.api.extension.AfterTestExecutionCallback
Standalone JUnit 6 extension that applies fault injection annotations to test methods.

Use this extension when you manage the CloudStub lifecycle yourself (e.g. via @BeforeAll / @AfterAll) rather than through CloudStubExtension. 

 static CloudStub cloudMock = new CloudStub();

 @BeforeAll
 static void start() { cloudMock.start(); }

 @AfterAll
 static void stop() { cloudMock.stop(); }

 @RegisterExtension
 FaultInjectionExtension faults = new FaultInjectionExtension(cloudMock);

 @SimulateThrottle(service = "sqs")
 @Test
 void throttleTest() { ... }

Fault state is always cleaned up after each test method, even if the test throws. If you use CloudStubExtension, fault annotation support is built in — you do not need this extension as well.
