TestExecutionListener (junit-platform-launcher 1.0.1 API)

All Known Implementing Classes:

LoggingListener, SummaryGeneratingListener
```
@API(status=STABLE,
     since="1.0")
public interface TestExecutionListener
```
Register an instance of this class with a Launcher to be notified of events that occur during test execution.
All methods in this class have empty default implementations. Concrete implementations may therefore override one or more of these methods to be notified of the selected events.
JUnit provides two example implementations:
- LoggingListener
- SummaryGeneratingListener
Contrary to JUnit 4, test engines are supposed to report events not only for identifiers that represent executable leaves in the test plan but also for all intermediate containers. However, while both the JUnit Vintage and JUnit Jupiter engines comply with this contract, there is no way to guarantee this for third-party engines.
Since:

1.0

Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method and Description
`default void`	`dynamicTestRegistered(TestIdentifier testIdentifier)` Called when a new, dynamic `TestIdentifier` has been registered.
`default void`	`executionFinished(TestIdentifier testIdentifier, org.junit.platform.engine.TestExecutionResult testExecutionResult)` Called when the execution of a leaf or subtree of the `TestPlan` has finished, regardless of the outcome.
`default void`	`executionSkipped(TestIdentifier testIdentifier, java.lang.String reason)` Called when the execution of a leaf or subtree of the `TestPlan` has been skipped.
`default void`	`executionStarted(TestIdentifier testIdentifier)` Called when the execution of a leaf or subtree of the `TestPlan` is about to be started.
`default void`	`reportingEntryPublished(TestIdentifier testIdentifier, org.junit.platform.engine.reporting.ReportEntry entry)` Called when additional test reporting data has been published for the supplied `TestIdentifier`.
`default void`	`testPlanExecutionFinished(TestPlan testPlan)` Called when the execution of the `TestPlan` has finished, after all tests have been executed.
`default void`	`testPlanExecutionStarted(TestPlan testPlan)` Called when the execution of the `TestPlan` has started, before any test has been executed.

- Method Detail
  - testPlanExecutionStarted
```
default void testPlanExecutionStarted(TestPlan testPlan)
```
    Called when the execution of the TestPlan has started, before any test has been executed.
    
    Parameters:
    
    testPlan - describes the tree of tests about to be executed
  - testPlanExecutionFinished
```
default void testPlanExecutionFinished(TestPlan testPlan)
```
    Called when the execution of the TestPlan has finished, after all tests have been executed.
    
    Parameters:
    
    testPlan - describes the tree of tests that have been executed
  - dynamicTestRegistered
```
default void dynamicTestRegistered(TestIdentifier testIdentifier)
```
    Called when a new, dynamic TestIdentifier has been registered.
    A dynamic test is a test that is not known a-priori and therefore not contained in the original TestPlan.
    
    Parameters:
    
    testIdentifier - the identifier of the newly registered test or container
  - executionSkipped
```
default void executionSkipped(TestIdentifier testIdentifier,
                              java.lang.String reason)
```
    Called when the execution of a leaf or subtree of the TestPlan has been skipped.
    The TestIdentifier may represent a test or a container. In the case of a container, no listener methods will be called for any of its descendants.
    A skipped test or subtree of tests will never be reported as started or finished.
    
    Parameters:
    
    testIdentifier - the identifier of the skipped test or container
    
    reason - a human-readable message describing why the execution has been skipped
  - executionStarted
```
default void executionStarted(TestIdentifier testIdentifier)
```
    Called when the execution of a leaf or subtree of the TestPlan is about to be started.
    The TestIdentifier may represent a test or a container.
    This method will only be called if the test or container has not been skipped.
    This method will be called for a container TestIdentifier before starting or skipping any of its children.
    
    Parameters:
    
    testIdentifier - the identifier of the started test or container
  - executionFinished
```
default void executionFinished(TestIdentifier testIdentifier,
                               org.junit.platform.engine.TestExecutionResult testExecutionResult)
```
    Called when the execution of a leaf or subtree of the TestPlan has finished, regardless of the outcome.
    The TestIdentifier may represent a test or a container.
    This method will only be called if the test or container has not been skipped.
    This method will 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 TestIdentifier. The result does not include or aggregate the results of its children. For example, a container with a failing test will be reported as SUCCESSFUL even if one or more of its children are reported as FAILED.
    
    Parameters:
    
    testIdentifier - the identifier of the finished test or container
    
    testExecutionResult - the (unaggregated) result of the execution for the supplied TestIdentifier

    TestExecutionResult
  - reportingEntryPublished
```
default void reportingEntryPublished(TestIdentifier testIdentifier,
                                     org.junit.platform.engine.reporting.ReportEntry entry)
```
    Called when additional test reporting data has been published for the supplied TestIdentifier.
    Can be called at any time during the execution of a test plan.
    
    Parameters:
    
    testIdentifier - describes the test or container to which the entry pertains
    
    entry - the published ReportEntry
