                NamespacedHierarchicalStore<Namespace> sessionLevelStore)

Construct a new DefaultLauncher with the supplied test engines.

Parameters:

testEngines - the test engines to delegate to; never null or empty

postDiscoveryFilters - the additional post discovery filters for discovery requests; never null

Method Detail

registerLauncherDiscoveryListeners

public void registerLauncherDiscoveryListeners(LauncherDiscoveryListener... listeners)

Description copied from interface: Launcher

Register one or more listeners for test discovery.

Specified by:

registerLauncherDiscoveryListeners in interface Launcher

Parameters:

listeners - the listeners to be notified of test discovery events; never null or empty

registerTestExecutionListeners

public void registerTestExecutionListeners(TestExecutionListener... listeners)

Description copied from interface: Launcher

Register one or more listeners for test execution.

Specified by:

registerTestExecutionListeners in interface Launcher

Parameters:

listeners - the listeners to be notified of test execution events; never null or empty

discover

public TestPlan discover(LauncherDiscoveryRequest discoveryRequest)

Description copied from interface: Launcher

Discover tests and build a TestPlan according to the supplied LauncherDiscoveryRequest by querying all registered engines and collecting their results.

Specified by:

discover in interface Launcher

Parameters:

discoveryRequest - the launcher discovery request; never null

Returns:

an unmodifiable TestPlan that contains all resolved identifiers from all registered engines

execute

public void execute(LauncherDiscoveryRequest discoveryRequest,
                    TestExecutionListener... listeners)

Description copied from interface: Launcher
