ClasspathRootSelector

- org.junit.platform.engine.discovery.ClasspathRootSelector

All Implemented Interfaces:

DiscoverySelector
```
@API(status=STABLE,
     since="1.0")
public class ClasspathRootSelector
extends java.lang.Object
implements DiscoverySelector
```
A DiscoverySelector that selects a classpath root so that TestEngines can search for class files or resources within the physical classpath — for example, to scan for test classes.
Since engines are not expected to modify the classpath, the classpath root represented by this selector must be on the classpath of the context class loader of the thread that uses this selector.

Since:

1.0

    Description copied from interface: DiscoverySelector
    
    Return the identifier of this selector.
    The returned identifier must be parsable by a corresponding DiscoverySelectorIdentifierParser.
    The default implementation returns Optional.empty(). Can be overridden by concrete implementations.
    
    Specified by:
    
    toIdentifier in interface DiscoverySelector
    
    Returns:
    
    an Optional containing the identifier of this selector; never null but potentially empty if the selector does not support identifiers
