public <T extends TestDescriptor> Optional<T>
addToParent(Function<TestDescriptor, Optional<T>> creator)

Implements org.junit.platform.engine.support.discovery.SelectorResolver.Context.addToParent.

Add a TestDescriptor to an unspecified parent, usually the engine descriptor, by applying the supplied Function to the new parent.

public <T extends TestDescriptor> Optional<T>
addToParent(Supplier<DiscoverySelector> parentSelectorSupplier, Function<TestDescriptor, Optional<T>> creator)

Implements org.junit.platform.engine.support.discovery.SelectorResolver.Context.addToParent.

Add a TestDescriptor to a parent, specified by the DiscoverySelector returned by the supplied Supplier, by applying the supplied Function to the new parent.

createAndAdd(TestDescriptor parent, Function<TestDescriptor, Optional<T>> creator)

public Optional<TestDescriptor>
resolve(DiscoverySelector selector)

Implements org.junit.platform.engine.support.discovery.SelectorResolver.Context.resolve.

Resolve the supplied TestDescriptor, if possible.

Implements org.junit.platform.engine.support.discovery.SelectorResolver.Context.addToParent.

Doc from org.junit.platform.engine.support.discovery.SelectorResolver.Context.addToParent.

Add a TestDescriptor to an unspecified parent, usually the engine descriptor, by applying the supplied Function to the new parent.

The parent will be the engine descriptor unless another parent has already been determined, i.e. if the selector that is being resolved is the result of expanding a Match.

If the result of applying the Function is present, it will be added as a child of the parent TestDescriptor unless a descriptor with the same unique ID was added earlier.

Implements org.junit.platform.engine.support.discovery.SelectorResolver.Context.addToParent.

Doc from org.junit.platform.engine.support.discovery.SelectorResolver.Context.addToParent.

Add a TestDescriptor to a parent, specified by the DiscoverySelector returned by the supplied Supplier, by applying the supplied Function to the new parent.

Unless another parent has already been determined, i.e. if the selector that is being resolved is the result of expanding a Match, the DiscoverySelector returned by the supplied Supplier will be used to determine the parent. If no parent is found, the supplied Function will not be called. If there are multiple potential parents, an exception will be thrown. Otherwise, the resolved TestDescriptor will be used as the parent and passed to the supplied Function.

If the result of applying the Function is present, it will be added as a child of the parent TestDescriptor unless a descriptor with the same unique ID was added earlier.

public Optional<TestDescriptor> resolve(DiscoverySelector selector)

Implements org.junit.platform.engine.support.discovery.SelectorResolver.Context.resolve.

Doc from org.junit.platform.engine.support.discovery.SelectorResolver.Context.resolve.

Resolve the supplied TestDescriptor, if possible.

Calling this method has the same effect as returning a partial match from a SelectorResolver: the children of the resulting TestDescriptor will only be resolved if a subsequent resolution finds an exact match that contains a TestDescriptor with the same unique ID.
