Interface EngineExecutionListener

@API(value=Experimental)
public interface EngineExecutionListener

Listener to be notified of test execution events by test engines.

Contrary to JUnit 4, test engines must report events not only for test descriptors that represent executable leaves but also for all intermediate containers.

Since:

1.0

Method Summary

Modifier and Type	Method and Description
void	dynamicTestRegistered(TestDescriptor testDescriptor) Must be called when a new, dynamic TestDescriptor has been registered.
void	executionFinished(TestDescriptor testDescriptor, TestExecutionResult testExecutionResult) Must be called when the execution of a leaf or subtree of the test tree has finished, regardless of the outcome.
void	executionSkipped(TestDescriptor testDescriptor, java.lang.String reason) Must be called when the execution of a leaf or subtree of the test tree has been skipped.
void	executionStarted(TestDescriptor testDescriptor) Must be called when the execution of a leaf or subtree of the test tree is about to be started.
void	reportingEntryPublished(TestDescriptor testDescriptor, ReportEntry entry) Can be called for any testDescriptor in order to publish additional information, e.g.: Output that would otherwise go to System.out Information about test context or test data

Method Detail

dynamicTestRegistered

void dynamicTestRegistered(TestDescriptor testDescriptor)

Must be called when a new, dynamic TestDescriptor has been registered.

A dynamic test is a test that is not known a-priori and therefore was not present in the test tree when discovering tests.

Parameters:

testDescriptor - the descriptor of the newly registered test or container

executionSkipped

void executionSkipped(TestDescriptor testDescriptor,
                      java.lang.String reason)

Must be called when the execution of a leaf or subtree of the test tree has been skipped.

The TestDescriptor may represent a test or a container. In the case of a container, engines must not fire any additional events for its descendants.

A skipped test or subtree of tests must not be reported as started or finished.

Parameters:

testDescriptor - the descriptor of the skipped test or container

reason - a human-readable message describing why the execution has been skipped

executionStarted

void executionStarted(TestDescriptor testDescriptor)

Must be called when the execution of a leaf or subtree of the test tree is about to be started.

The TestDescriptor may represent a test or a container. In the case of a container, engines have to fire additional events for its children.

This method may only be called if the test or container has not been skipped.

This method must be called for a container TestDescriptor before starting or skipping any of its children.

Parameters:

testDescriptor - the descriptor of the started test or container

executionFinished

void executionFinished(TestDescriptor testDescriptor,
                       TestExecutionResult testExecutionResult)

Must be called when the execution of a leaf or subtree of the test tree has finished, regardless of the outcome.

The TestDescriptor may represent a test or a container.

This method may only be called if the test or container has not been skipped.

This method must be called for a container TestIdentifier after all of its children have been skipped or have finished.

The TestExecutionResult describes the result of the execution for the supplied testDescriptor. The result does not include or aggregate the results of its children. For example, a container with a failing test must be reported as SUCCESSFUL even if one or more of its children are reported as FAILED.

Parameters:

testDescriptor - the descriptor of the finished test or container

testExecutionResult - the (unaggregated) result of the execution for the supplied TestDescriptor

TestExecutionResult

reportingEntryPublished

void reportingEntryPublished(TestDescriptor testDescriptor,
                             ReportEntry entry)

Can be called for any testDescriptor in order to publish additional information, e.g.:

• Output that would otherwise go to System.out
• Information about test context or test data

The current lifecycle state of testDescriptor is not relevant; that means that reporting events can occur at all times.

Parameters:

testDescriptor - the descriptor of the test or container to which the entry belongs

entry - a ReportEntry instance to be published
