Package rife.bld.extension.testing

Class RetryExtension

java.lang.Object

rife.bld.extension.testing.RetryExtension

All Implemented Interfaces:

Extension, TestTemplateInvocationContextProvider

public class RetryExtension
extends Object
implements TestTemplateInvocationContextProvider

JUnit extension that provides retry functionality for failing tests.

This extension implements TestTemplateInvocationContextProvider to create multiple invocations of a test method when failures occur.

The extension works by:

1. Detecting methods annotated with @RetryTest
2. Creating multiple test invocation contexts
3. Tracking failures and successes across invocations
4. Stopping retries when a test passes or max retries are reached

Usage: Apply the @RetryTest annotation to test methods that should be retried on failure.

Since:

1.0

supportsTestTemplate

public boolean supportsTestTemplate(ExtensionContext context)

Determines if this extension supports the given test context.

Returns true if the test method is annotated with @RetryTest.

Specified by:

supportsTestTemplate in interface TestTemplateInvocationContextProvider

Parameters:

context - the extension context for the test

Returns:

true if the test method is annotated with @RetryTest, false otherwise

provideTestTemplateInvocationContexts

public Stream<TestTemplateInvocationContext> provideTestTemplateInvocationContexts(ExtensionContext context)

Provides invocation contexts for retry attempts.

Creates a stream of invocation contexts based on the retry count specified in the @RetryTest annotation.

Specified by:

provideTestTemplateInvocationContexts in interface TestTemplateInvocationContextProvider

Parameters:

context - the extension context for the test

Returns:

a stream of TestTemplateInvocationContext for each retry attempt
