Class NestedClassSelector

java.lang.Object

org.junit.platform.engine.discovery.NestedClassSelector

All Implemented Interfaces:

DiscoverySelector

@API(status=STABLE,
     since="1.6")
public class NestedClassSelector
extends java.lang.Object
implements DiscoverySelector

A DiscoverySelector that selects a nested Class or class name enclosed in other classes so that TestEngines can discover tests or containers based on classes.

If Java Class references are provided for the nested class or the enclosing classes, the selector will return those classes and their class names accordingly. If class names are provided, the selector will only attempt to lazily load classes if getEnclosingClasses() or getNestedClass() is invoked.

In this context, Java Class means anything that can be referenced as a Class on the JVM — for example, classes from other JVM languages such Groovy, Scala, etc.

Since:

1.6

NestedClassSelector

NestedClassSelector(java.lang.ClassLoader classLoader,
                    java.util.List<java.lang.String> enclosingClassNames,
                    java.lang.String nestedClassName)

Method Detail

getClassLoader

@API(status=EXPERIMENTAL,
     since="1.10")
public java.lang.ClassLoader getClassLoader()

Get the ClassLoader used to load the selected nested class.

Returns:

the ClassLoader; potentially null

Since:

1.10

getEnclosingClassNames

public java.util.List<java.lang.String> getEnclosingClassNames()

Get the names of the classes enclosing the selected nested class.

getEnclosingClasses

public java.util.List<java.lang.Class<?>> getEnclosingClasses()

Get the list of Class enclosing the selected nested Class.

If the Class were not provided, but only the name of the nested class and its enclosing classes, this method attempts to lazily load the list of enclosing Class and throws a PreconditionViolationException if the classes cannot be loaded.

getNestedClassName

public java.lang.String getNestedClassName()

Get the name of the selected nested class.

getNestedClass

public java.lang.Class<?> getNestedClass()

Get the selected nested Class.

If the Class were not provided, but only the name of the nested class and its enclosing classes, this method attempts to lazily load the nested Class and throws a PreconditionViolationException if the class cannot be loaded.
