@API(status=STABLE,
since="1.0")
public interface Launcher
Launcher
API is the main entry point for client code that
wishes to discover and execute tests using one or more
test engines.
Implementations of this interface are responsible for determining
the set of test engines to delegate to at runtime and for ensuring that
each test engine has an
ID that is unique
among the registered test engines. For example, the default implementation
returned by LauncherFactory.create()
dynamically discovers test engines via Java's ServiceLoader
mechanism.
Test discovery and execution require a LauncherDiscoveryRequest
that is passed to all registered engines. Each engine decides which tests it
can discover and execute according to the supplied request.
Prior to executing tests, clients of this interface should
register one or more
TestExecutionListener
instances in order to get feedback about the
progress and results of test execution. Listeners will be notified of events
in the order in which they were registered. The default implementation
returned by LauncherFactory.create()
dynamically discovers test execution listeners via Java's
ServiceLoader
mechanism.

execute(LauncherDiscoveryRequest launcherDiscoveryRequest,
TestExecutionListener... listeners)
Execute a
TestPlan which is built according to the supplied
LauncherDiscoveryRequest by querying all registered engines and
collecting their results, and notify
registered listeners about
the progress and results of the execution. |

Execute the supplied
TestPlan and notify
registered listeners about
the progress and results of the execution. |
