Module org.junit.jupiter.engine

Package org.junit.jupiter.engine.extension

Class RepetitionExtension

java.lang.Object

org.junit.jupiter.engine.extension.RepetitionExtension

All Implemented Interfaces:

ExecutionCondition, Extension, ParameterResolver, TestWatcher

class RepetitionExtension
extends Object
implements ParameterResolver, TestWatcher, ExecutionCondition

RepetitionExtension implements the following extension APIs to support repetitions of a @RepeatedTest method.

• ParameterResolver to resolve RepetitionInfo arguments
• TestWatcher to track the failure count
• ExecutionCondition to disable the repetition if the failure threshold has been exceeded

Since:

5.0

Method Details

supportsParameter

public boolean supportsParameter(ParameterContext parameterContext,
 ExtensionContext extensionContext)

Description copied from interface: ParameterResolver

Determine if this resolver supports resolution of an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

The Method or Constructor in which the parameter is declared can be retrieved via ParameterContext.getDeclaringExecutable().

Specified by:

supportsParameter in interface ParameterResolver

Parameters:

parameterContext - the context for the parameter for which an argument should be resolved; never null

extensionContext - the extension context for the Executable about to be invoked; never null

Returns:

true if this resolver can resolve an argument for the parameter

• ParameterResolver.resolveParameter(org.junit.jupiter.api.extension.ParameterContext, org.junit.jupiter.api.extension.ExtensionContext)
• ParameterContext

resolveParameter

public RepetitionInfo resolveParameter(ParameterContext parameterContext,
 ExtensionContext extensionContext)

Description copied from interface: ParameterResolver

Resolve an argument for the Parameter in the supplied ParameterContext for the supplied ExtensionContext.

This method is only called by the framework if ParameterResolver.supportsParameter(org.junit.jupiter.api.extension.ParameterContext, org.junit.jupiter.api.extension.ExtensionContext) previously returned true for the same ParameterContext and ExtensionContext.

The Method or Constructor in which the parameter is declared can be retrieved via ParameterContext.getDeclaringExecutable().

Specified by:

resolveParameter in interface ParameterResolver

Parameters:

parameterContext - the context for the parameter for which an argument should be resolved; never null

extensionContext - the extension context for the Executable about to be invoked; never null

Returns:

the resolved argument for the parameter; may only be null if the parameter type is not a primitive

See Also:

• ParameterResolver.supportsParameter(org.junit.jupiter.api.extension.ParameterContext, org.junit.jupiter.api.extension.ExtensionContext)
• ParameterContext

testFailed

public void testFailed(ExtensionContext context,
 Throwable cause)

Description copied from interface: TestWatcher

Invoked after a test has failed.

The default implementation does nothing. Concrete implementations can override this method as appropriate.

Specified by:

testFailed in interface TestWatcher

Parameters:

context - the current extension context; never null

cause - the throwable that caused test failure; may be null

evaluateExecutionCondition

public ConditionEvaluationResult evaluateExecutionCondition(ExtensionContext context)

Description copied from interface: ExecutionCondition

Evaluate this condition for the supplied ExtensionContext.

An enabled result indicates that the container or test should be executed; whereas, a disabled result indicates that the container or test should not be executed.

Specified by:

evaluateExecutionCondition in interface ExecutionCondition

Parameters:

context - the current extension context; never null

Returns:

the result of evaluating this condition; never null
