Field Detail

children

protected final Set<TestDescriptor> children

The synchronized set of children associated with this TestDescriptor.

This set is used in methods such as addChild(TestDescriptor), removeChild(TestDescriptor), removeFromHierarchy(), and findByUniqueId(UniqueId), and an immutable copy of this set is returned by getChildren().

If a subclass overrides any of the methods related to children, this set should be used instead of a set local to the subclass.

Constructor Detail

AbstractTestDescriptor

protected AbstractTestDescriptor(UniqueId uniqueId,
                                 String displayName)

Create a new AbstractTestDescriptor with the supplied UniqueId and display name.

Parameters:

uniqueId - the unique ID of this TestDescriptor; never null

displayName - the display name for this TestDescriptor; never null or blank

See Also:

AbstractTestDescriptor(UniqueId, String, TestSource)

AbstractTestDescriptor

protected AbstractTestDescriptor(UniqueId uniqueId,
                                 String displayName,
                                 TestSource source)

Create a new AbstractTestDescriptor with the supplied UniqueId, display name, and source.

Parameters:

uniqueId - the unique ID of this TestDescriptor; never null

displayName - the display name for this TestDescriptor; never null or blank

source - the source of the test or container described by this TestDescriptor; can be null

AbstractTestDescriptor(UniqueId, String)

Method Detail

getUniqueId

public final UniqueId getUniqueId()

Description copied from interface: TestDescriptor

Get the unique identifier (UID) for this descriptor.

Uniqueness must be guaranteed across an entire test plan, regardless of how many engines are used behind the scenes.

Specified by:

getUniqueId in interface TestDescriptor

Returns:

the UniqueId for this descriptor; never null

getDisplayName

public final String getDisplayName()

Description copied from interface: TestDescriptor

Get the display name for this descriptor.

A display name is a human-readable name for a test or container that is typically used for test reporting in IDEs and build tools. Display names may contain spaces, special characters, and emoji, and the format may be customized by TestEngines or potentially by end users as well. Consequently, display names should never be parsed; rather, they should be used for display purposes only.

Specified by:

getDisplayName in interface TestDescriptor

Returns:

the display name for this descriptor; never null or blank

See Also:

TestDescriptor.getSource()

getTags

public Set<TestTag> getTags()

Description copied from interface: TestDescriptor

Get the set of tags associated with this descriptor.

Specified by:

getTags in interface TestDescriptor

Returns:

the set of tags associated with this descriptor; never null but potentially empty

See Also:

TestTag

getSource

public Optional<TestSource> getSource()

Description copied from interface: TestDescriptor

Get the source of the test or container described by this descriptor, if available.

Specified by:

getSource in interface TestDescriptor

See Also:

TestSource

getParent

public final Optional<TestDescriptor> getParent()

Description copied from interface: TestDescriptor

Get the parent of this descriptor, if available.

Specified by:

getParent in interface TestDescriptor

setParent

public final void setParent(TestDescriptor parent)

Description copied from interface: TestDescriptor

Set the parent of this descriptor.

Specified by:

setParent in interface TestDescriptor

Parameters:

parent - the new parent of this descriptor; may be null.

getChildren

public final Set<? extends TestDescriptor> getChildren()

Description copied from interface: TestDescriptor

Get the immutable set of children of this descriptor.

Specified by:

getChildren in interface TestDescriptor

Returns:

the set of children of this descriptor; neither null nor mutable, but potentially empty

See Also:

TestDescriptor.getDescendants()

addChild

public void addChild(TestDescriptor child)

Description copied from interface: TestDescriptor

Add a child to this descriptor.

Specified by:

addChild in interface TestDescriptor

Parameters:

child - the child to add to this descriptor; never null

removeChild

public void removeChild(TestDescriptor child)

Description copied from interface: TestDescriptor

Remove a child from this descriptor.

Specified by:

removeChild in interface TestDescriptor

Parameters:

child - the child to remove from this descriptor; never null

removeFromHierarchy

public void removeFromHierarchy()

Description copied from interface: TestDescriptor

Remove this non-root descriptor from its parent and remove all the children from this descriptor.

If this method is invoked on a root descriptor, this method must throw a JUnitException explaining that a root cannot be removed from the hierarchy.

Specified by:

removeFromHierarchy in interface TestDescriptor

findByUniqueId

public Optional<? extends TestDescriptor> findByUniqueId(UniqueId uniqueId)

Description copied from interface: TestDescriptor

Find the descriptor with the supplied unique ID.

The search algorithm begins with this descriptor and then searches through its descendants.

Specified by:

findByUniqueId in interface TestDescriptor

Parameters:

uniqueId - the UniqueId to search for; never null

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

equals

public final boolean equals(Object other)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
