Method Detail

getId

public java.lang.String getId()

Description copied from interface: TestEngine

Get the ID that uniquely identifies this test engine.

Each test engine must provide a unique ID. For example, JUnit Vintage and JUnit Jupiter use "junit-vintage" and "junit-jupiter", respectively. When in doubt, you may use the fully qualified name of your custom TestEngine implementation class.

getGroupId

public java.util.Optional<java.lang.String> getGroupId()

Returns org.junit.jupiter as the group ID.

Returns:

an Optional containing the group ID; never null but potentially empty if the group ID is unknown

See Also:

TestEngine.getArtifactId(), TestEngine.getVersion()

getArtifactId

public java.util.Optional<java.lang.String> getArtifactId()

Returns junit-jupiter-engine as the artifact ID.

Returns:

an Optional containing the artifact ID; never null but potentially empty if the artifact ID is unknown

Class.getPackage(), Package.getImplementationTitle(), TestEngine.getGroupId(), TestEngine.getVersion()

discover

public TestDescriptor discover(EngineDiscoveryRequest discoveryRequest,
                               UniqueId uniqueId)

Description copied from interface: TestEngine

Discover tests according to the supplied EngineDiscoveryRequest.

The supplied UniqueId must be used as the unique ID of the returned root TestDescriptor. In addition, the UniqueId must be used to create unique IDs for children of the root's descriptor by calling UniqueId.append(java.lang.String, java.lang.String).

Parameters:

discoveryRequest - the discovery request; never null

uniqueId - the unique ID to be used for this test engine's TestDescriptor; never null

Returns:

the root TestDescriptor of this engine, typically an instance of EngineDescriptor

EngineDescriptor

createExecutionContext

protected JupiterEngineExecutionContext createExecutionContext(ExecutionRequest request)

Description copied from class: HierarchicalTestEngine

Create the initial execution context for executing the supplied request.

Specified by:

createExecutionContext in class HierarchicalTestEngine<JupiterEngineExecutionContext>

Parameters:

request - the request about to be executed

Returns:

the initial context that will be passed to nodes in the hierarchy
